On the potential advantages of making model-specific GPU kernels and their software to optimizing the usage of dynamically formed tensors
This put up continues a protracted sequence of posts on the subject of analyzing and optimizing the runtime efficiency of coaching AI/ML fashions. The put up may simply have been titled “PyTorch Mannequin Efficiency Evaluation and Optimization — Half 7”, however because of the weight of the subject at hand, we determined {that a} devoted put up (or sequence of posts) was warranted. In our earlier posts, we have now spoken at size in regards to the significance of analyzing and optimizing your AI/ML workloads and the possibly vital impression it may have on the velocity and prices of AI/ML mannequin growth. We have now advocated for having a number of instruments and strategies for profiling and optimizing coaching efficiency and have demonstrated many of those in follow. On this put up we are going to talk about one of many extra superior optimization strategies — one which units aside the true rock stars from the easy amateurs — making a customized PyTorch operator in C++ and CUDA.
Well-liked ML frameworks, corresponding to PyTorch, TensorFlow, and JAX are usually constructed utilizing SW elements which are optimized for the underlying {hardware} that the AI/ML workload is run on, be it a CPU, a GPU, or an AI-specific ASIC corresponding to a Google TPU. Nonetheless, inevitably, chances are you’ll discover the efficiency of sure computation blocks that comprise your mannequin to be unsatisfactory or in-optimal. Oftentimes, by tuning the low-level code blocks — sometimes called kernels — to the precise wants of the AI/ML mannequin, can lead to vital speed-ups to the runtime efficiency of mannequin coaching and inference. Such speed-ups will be completed by implementing functionalities that had been beforehand unsupported (e.g., a sophisticated consideration block), fusing collectively particular person operations (e.g., as in PyTorch’s tutorial on multiply-add fusion), and/or optimizing present kernels primarily based on the precise properties of the mannequin at hand. Importantly, the flexibility to carry out such customization relies on the help of each the AI HW and the ML framework. Though our deal with this put up can be on NVIDIA GPUs and the PyTorch framework, it needs to be famous that different AI ASICs and ML frameworks allow related capabilities for customized kernel customization. NVIDIA allows the event of customized kernels for its GPUs by means of its CUDA toolkit. And PyTorch contains devoted APIs and tutorials for exposing this performance and integrating it into the design of your mannequin.
Our intention on this put up is to attract consideration to the ability and potential of kernel customization and reveal its software to the distinctive problem of coaching fashions with dynamically formed tensors. Our intention isn’t — by any means — to switch the official documentation on growing customized operations. Moreover, the examples we are going to share had been chosen for demonstrative functions, solely. We have now made no effort to optimize these or confirm their robustness, sturdiness, or accuracy. If, primarily based on this put up, you select to put money into AI/ML optimization through customized CUDA kernel growth, it is best to make sure you endure the suitable coaching.
The prevalence of tensors with dynamic shapes in AI fashions can pose distinctive and thrilling challenges on the subject of efficiency optimization. We have now already seen one instance of this in a earlier put up during which we demonstrated how the usage of boolean masks can set off a undesired CPU-GPU sync occasion and advocated in opposition to their use. Typically talking, AI accelerators are likely to favor tensors with fastened shapes over ones with dynamic shapes. Not solely does it simplify the administration of reminiscence assets, nevertheless it additionally allows larger alternative for efficiency optimization (e.g., utilizing torch.compile). The toy instance that follows demonstrates this problem.
Suppose we’re tasked with making a face detection mannequin for a next-generation digital digicam. To coach, this mannequin, we’re supplied with a dataset of 1 million 256x256 grayscale pictures and related ground-truth bounding bins for every picture. Naturally, the variety of faces in every picture can differ enormously, with the overwhelming majority of pictures containing 5 or fewer faces, and only a few containing dozens and even a whole lot. The requirement from our mannequin is to help all variations. Particularly, our mannequin must help the detection of as much as 256 faces in a picture.
To deal with this problem, we outline the next naïve mannequin that generates bounding bins and an accompanying loss operate. Particularly, we naïvely truncate the mannequin outputs primarily based on the variety of goal bins somewhat than carry out some type of task algorithm for matching between the bounding field predictions and floor fact targets. We (considerably arbitrarily) select the Generalized Intersection Over Union (GIOU) loss. An actual-world resolution would seemingly be way more subtle (e.g., it could embrace a loss element that features a penalizes for false positives).

def loss_fn(pred, targets_list):

sample_preds = pred[i, :num_targets]
total_boxes += num_targets
loss_sum += generalized_box_iou(sample_preds, targets).sum()
return loss_sum / max(total_boxes, 1)
Due the various variety of faces per picture, the loss is calculated individually for every particular person pattern somewhat than a single time (for your entire batch). Particularly, the CPU will launch every of the GPU kernels related to the loss operate B instances, the place B is the chosen batch dimension. Relying on the scale of the batch, this might entail a big overhead, as we are going to see under.
Within the following block we outline a dataset that generates random pictures and related bounding bins. Because the variety of faces varies per picture, we require a customized collate operate for grouping samples into batches:
from torch.utils.knowledge import Dataset, DataLoader
import numpy as np# A dataset with random pictures and gt bins
class FakeDataset(Dataset):
def __init__(self):
tremendous().__init__()
self.dimension = 256
self.img_size = [256, 256]
def __len__(self):
return 1000000
def __getitem__(self, index):
rand_image = torch.randint(low=0, excessive=256,
dimension=[1]+self.img_size,
dtype=torch.uint8)
# set the distribution over the variety of bins to mirror the actual fact
# that the overwhelming majority of pictures have fewer than 10 faces
n_boxes = np.clip(np.ground(np.abs(np.random.regular(0, 3)))
.astype(np.int32), 0, 255)
box_sizes = torch.randint(low=1, excessive=self.dimension, dimension=(n_boxes,2))
top_left = torch.randint(low=0, excessive=self.size-1, dimension=(n_boxes, 2))
bottom_right = torch.clamp(top_left + box_sizes, 0, self.dimension -1)
rand_boxes = torch.concat((top_left,bottom_right), dim = 1)
return rand_image, rand_boxes.to(torch.uint8)
def collate_fn(batch):
pictures = torch.stack([b[0] for b in batch],dim=0)
bins = [b[1] for b in batch]
return pictures, bins
train_loader = DataLoader(
dataset = FakeDataset(),
batch_size=1024,
pin_memory=True,
num_workers=16,
collate_fn=collate_fn
)
Usually, every coaching step begins with copying the coaching batch from the host (CPU) to the system (GPU). When our knowledge samples are of fastened sized, they’re copied in batches. Nonetheless, one of many implications of the various variety of faces per picture is that the bounding field targets of every pattern is copied individually requiring many extra particular person copy operations.
def data_to_device(knowledge, system):
if isinstance(knowledge, (record, tuple)):
return kind(knowledge)(
data_to_device(val, system) for val in knowledge
)
elif isinstance(knowledge, torch.Tensor):
return knowledge.to(system=system, non_blocking=True)
Lastly, we outline our coaching/analysis loop. For the needs of our dialogue, we have now chosen to focus simply on the ahead go of our coaching loop. Observe the inclusion of a PyTorch profiler object and our use of express synchronization occasions (to facilitate efficiency analysis of various parts of the ahead go).
system = torch.system("cuda:0")
mannequin = torch.compile(Web()).to(system).prepare()# ahead portion of coaching loop wrapped with profiler object
with torch.profiler.profile(
schedule=torch.profiler.schedule(wait=5, warmup=5, lively=10, repeat=1),
on_trace_ready=torch.profiler.tensorboard_trace_handler('/tmp/perf/'),
profile_memory=True
) as prof:
for step, knowledge in enumerate(train_loader):
with torch.profiler.record_function('copy knowledge'):
pictures, bins = data_to_device(knowledge, system)
torch.cuda.synchronize(system)
with torch.profiler.record_function('ahead'):
with torch.autocast(device_type='cuda', dtype=torch.bfloat16):
outputs = mannequin(pictures)
torch.cuda.synchronize(system)
with torch.profiler.record_function('calc loss'):
loss = loss_fn(outputs, bins)
torch.cuda.synchronize(system)
prof.step()
if step > 30:
break
# filter and print profiler outcomes
event_list = prof.key_averages()
for i in vary(len(event_list) - 1, -1, -1):
if event_list[i].key not in ['forward', 'calc loss', 'copy data']:
del event_list[i]
print(event_list.desk())
Efficiency Evaluation
Working our script on a Google Cloud g2-standard-16 VM (with a single L4 GPU), a devoted deep studying VM picture, and PyTorch 2.4.0, generates the output under (which we trimmed for readability).
------------- ------------ ------------

copy knowledge 288.164ms 28.816ms

calc loss 9.381s 938.067ms
------------- ------------ ------------
Self CPU time complete: 4.018s
Self CUDA time complete: 10.107s
Even though the loss operate accommodates far fewer operations, it utterly dominates the general step time. The overhead of the repeated invocations of the underlying GPU kernels (for every pattern within the batch) is clearly evident within the Hint view in TensorBoard:
Optimization By Concatenation
One option to scale back the variety of calls to the loss operate is to mix collectively the entire legitimate bins every batch utilizing concatenation, as proven within the following block.
def loss_with_concat(pred, targets_list):
bs = len(targets_list)
all_targets = torch.concat(targets_list, dim = 0)
num_boxes = [targets_list[i].form[0] for i in vary(bs)]
all_preds = torch.concat([pred[i,: num_boxes[i]] for i in vary(bs)],
dim=0)
total_boxes = sum(num_boxes)
loss_sum = generalized_box_iou(all_targets, all_preds).sum()
return loss_sum/max(total_boxes, 1)
The outcomes of this optimization are captured under.

calc loss 254.047ms 25.405ms
------------- ------------ ------------
Self CPU time complete: 396.674ms
Self CUDA time complete: 1.871s
The concatenation optimization resulted in a 37X (!!) speed-up of the loss operate. Observe, nevertheless, that it didn’t tackle the overhead of the person host-to-device copies of the pattern ground-truth knowledge. This overhead is captured within the screenshot under from TensorBoard’s Hint view:
Optimization By Padding
A typical method to avoiding the usage of dynamically formed tensors is padding. Within the following code block, we modify the collate operate to pad (with zeros) the ground-truth bounding-boxes of every knowledge pattern to the utmost variety of supported bins, 256. (Observe, that the padding may even have been carried out within the Dataset class.)
def collate_with_padding(batch):
pictures = torch.stack([b[0] for b in batch],dim=0)
padded_boxes = []
for b in batch:
p = torch.nn.practical.pad(
b[1], (0, 0, 0, 256 - b[1].form[0]), worth = 0)
padded_boxes.append(p)
bins = torch.stack(padded_boxes,dim=0)
return pictures, bins
Padding the samples to fastened sized tensors allows us to repeat the bottom fact of the batch with a single name. It additionally permits us to compute the loss with a single invocation of the loss operate. Observe, that this technique requires masking the resultant loss, as proven under, in order that solely the legitimate bins are considered.
def loss_with_padding(pred, targets):
masks = (targets[...,3] > 0).to(pred.dtype)
total_boxes = masks.sum()
loss = generalized_box_iou(targets, pred)
masked_loss = loss*masks
loss_sum = masked_loss.sum()
return loss_sum/torch.clamp(total_boxes, 1)
The resultant runtime efficiency is captured under:
------------- ------------ ------------
Identify CPU complete CPU time avg
------------- ------------ ------------
copy knowledge 57.125ms 5.713ms
ahead 1.315s 131.503ms
calc loss 18.438ms 1.844ms
------------- ------------ ------------
Self CPU time complete: 11.723ms
Self CUDA time complete: 1.378s
Observe the practically 10X enhance within the knowledge copy and the extra 14X enhance within the loss operate efficiency. Remember that padding could enhance the usage of the GPU reminiscence. In our case, this enhance is lower than 1%.
Whereas the runtime of our loss operate has improved dramatically, we observe that the overwhelming majority of the calculations which are carried out within the loss features are instantly masked away. We will’t assist however ponder whether there’s a option to additional enhance the efficiency by avoiding these redundant operations. Within the subsequent part, we are going to discover the alternatives offered through the use of customized CUDA kernels.
Many tutorials will spotlight the problem of making CUDA kernels and the excessive entrance barrier. Whereas mastering CUDA growth and tuning kernels to maximise the utilization of the GPU may, certainly, require years of expertise in addition to an intimate understanding of the GPU structure, we strongly imagine that even a novice (however bold) CUDA fanatic/ML developer can succeed at — and enormously profit from — constructing customized CUDA kernels. On this part we are going to take PyTorch’s (comparatively easy) instance of a C++/CUDA extension for PyTorch and improve it with a GIOU kernel. We are going to do that in two phases: First we are going to naïvely carry over the entire GIOU logic to C++/CUDA to evaluate the efficiency impression of kernel fusion. Then, we are going to benefit from our new-found low-level management so as to add conditional logic and scale back unneeded arithmetic operations.
Creating CUDA kernels permits you to decide the core logic that’s carried out in every of the GPU threads and the way these are distributed onto the underlying GPU streaming multiprocessors (SMs). Doing this in probably the most optimum method requires an professional understanding of the GPU structure together with the completely different ranges of GPU reminiscence, reminiscence bandwidth, the on-chip acceleration engines (e.g., TensorCores), the supported variety of concurrent threads per SM and the way they’re scheduled, and far rather more. What makes issues much more sophisticated is that these properties can differ between GPU generations and flavors. See this weblog for a really primary, however very simple, introduction to CUDA.
Step 1 — Kernel Fusion
Trying again on the Hint view of our final experiment, chances are you’ll discover that the ahead go of our loss calculation contains roughly thirty impartial arithmetic operations which of which translate to launching and operating an impartial CUDA kernel (as will be seen by merely counting the variety of cudaLaunchKernel occasions). This may negatively impression efficiency in numerous methods. For instance:
- Every kernel launch requires devoted communication between the CPU and GPU — one thing we all the time attempt to decrease.
- Every kernel wants to attend for the earlier kernel to be accomplished earlier than operating. Generally, this will’t be averted, however in some instances, corresponding to ours — the place many of the operations are carried out “per-pixel”, it may.
- The usage of many impartial kernels can have implications on how the GPU reminiscence is used.
Optimization by means of kernel fusion makes an attempt to cut back this overhead by combining these operations right into a decrease variety of kernels in order to cut back the overhead of a number of kernels.
Within the code block under, we outline a kernel that performs our GIOU on a single bounding-box prediction-target pair. We use a 1-D grid to allocate thread blocks of dimension 256 every the place every block corresponds one pattern within the coaching batch and every thread corresponds to at least one bounding field within the pattern. Thus, every thread — uniquely recognized by a mixture of the block and thread IDs — receives the predictions (boxes1) and targets(boxes2) and performs the GIOU calculation on the one bounding field decided by the IDs. As earlier than, the “validity” of the bounding field is managed by the worth of the goal bins. Particularly, the GIOU is explicitly zeroed wherever the corresponding field is invalid.

}
// Registers CUDA implementations for giou_loss
TORCH_LIBRARY_IMPL(extension_cpp, CUDA, m) {
m.impl("giou_loss", &giou_loss_cuda);
}
}
To finish the kernel creation, we have to add the suitable C++ and Python operator definitions (see muladd.cpp and ops.py)
// Add the C++ definition
m.def(“giou_loss(Tensor a, Tensor b) -> Tensor”);
# outline the Python operator
def giou_loss(a: Tensor, b: Tensor) -> Tensor:
return torch.ops.extension_cpp.giou_loss.default(a, b)
To compile our kernel run the set up script (pip set up .) from the bottom listing.
The next block makes use of our newly outlined GIOU CUDA kernel:
def loss_with_kernel(pred, targets):
pred = pred.to(torch.float32)
targets = targets.to(torch.float32)
import extension_cpp
return extension_cpp.ops.giou_loss(pred, targets)
Observe the express casting to torch.float32. It is a somewhat costly operation that could possibly be simply averted by enhancing our CUDA kernel help. We go away this as an train to the reader :).
The outcomes of operating our script with our customized kernel are displayed under.

------------- ------------ ------------
Self CPU time complete: 6.907ms
Self CUDA time complete: 1.380s
Regardless of the naïveté of our kernel (and our inexperience at CUDA), we have now boosted the loss operate efficiency by an extra ~3X over our earlier experiment (628 microseconds evaluate to 1.8 milliseconds). With some extra. As famous above, this may be improved even additional with out a lot effort.
Step 2 — Conditional Execution
The thread-level management that CUDA gives us permits us so as to add a conditional assertion that avoids computation on the invalid bounding bins:
__global__ void giou_kernel(const float* boxes1,
const float* boxes2,
float* giou,
bool* masks) {
int idx = blockIdx.x * blockDim.x + threadIdx.x;
bool legitimate = boxes2[4*idx+3] != 0;
masks[idx] = legitimate;
if (legitimate)
{
const float* box1 = &boxes1[idx * 4];
const float* box2 = &boxes2[idx * 4];
giou[idx] = compute_giou(box1, box2);
}
else
{
giou[idx] = 0;
}
}
Within the case of our kernel, the impression on runtime efficiency is negligible. The explanation for this (presumably) is that our kernel is comparatively small to the purpose that its runtime is negligible in comparison with the time require to load and instantiate it. The impression of our conditional execution may solely change into obvious for bigger kernels. (The impression, as a operate of the kernel dimension will be assessed by making our GIOU output depending on a for loop that we run for a various variety of fastened steps. This, too, we go away as an train :).) It is usually necessary to consider how a conditional execution flows behave on CUDA’s SIMT structure, significantly, the potential efficiency penalty when threads belonging to the identical warp diverge.

We summarize the outcomes of our experiments within the desk under.
Importantly, our work isn’t achieved. Admittedly, we have now taken some shortcuts within the instance we have now shared:
- With a purpose to use our customized kernel for coaching, we would wish to implement the backward go. Usually, this is usually a bit extra sophisticated than the ahead go.
- We have now fastened each the tensor sorts (to float32) and tensor shapes (to 256 bins per pattern). Ideally, a extra strong resolution is desired that helps various enter sorts and shapes.
- We restricted our experiments to a single GPU kind. In actuality, we’d need our implementation to help (and be examined on) a number of GPUs.
- We have now utterly uncared for alternatives for kernel optimization — a few of which can require larger CUDA experience than we have now demonstrated right here.
On this put up we demonstrated the potential of the usage of a customized CUDA kernel on the runtime efficiency of AI/ML functions. We tried, specifically, to make the most of the low-level management enabled by CUDA to introduce a conditional movement to restrict the variety of redundant arithmetic operations within the case of dynamically formed inputs. Whereas the efficiency enhance ensuing from the fusion of a number of kernel operations was vital, we discovered the scale of our kernel to be too small to learn from the conditional execution movement.
All through lots of our posts we have now emphasised the significance of getting a number of instruments and strategies for optimizing ML and decreasing its prices. Customized kernel growth is likely one of the strongest strategies at our disposal. Nonetheless, for a lot of AI/ML engineers, additionally it is probably the most intimidating strategies. We hope that we have now succeeded in convincing you that this chance is inside attain of any ML developer and that it doesn’t require main specialization in CUDA.
Lately, new frameworks have been launched with the aim of creating customized kernel growth and optimization extra accessible to AI/ML builders. Probably the most standard of those frameworks is Triton. In our subsequent put up we are going to proceed our exploration of the subject of customized kernel growth by assessing the capabilities and potential impression of growing Triton kernels.
