This week we're attending the ai.engineer conference in San Francisco.
We are thrilled to have a booth! Please join us at S18.
By adding more metrics, our continuous profiling for GPUs product now includes detailed clock speed, PCIe throughput data, and temperature, providing deeper contextual insights into performance and potential bottlenecks.
Expanded Metric Collection
Clock Speed Metrics
GPUs aggressively throttle when hitting temperature limits (typically 83-87°C). You'll see clock speeds drop in steps, sometimes losing 200-300MHz, directly impacting frame rates and rendering performance.
Temperature Metrics
Modern GPUs operate safely up to specific temperature limits, typically 83-87°C for most consumer cards. Understanding these thresholds helps you recognize when your card approaches dangerous territory.
PCIe Throughput Metrics
Modern high-end GPUs can saturate PCIe bandwidth during specific scenarios. Monitoring reveals when the PCIe bus becomes the limiting factor rather than GPU processing power.
Per-Process Utilization Metrics
Process-level GPU utilization tracking in PyTorch environments provides granular visibility into how individual training processes, data loaders, and model components consume GPU resources, enabling precise optimization of machine learning workflows.
Drill down into a node, GPU, and process by process ID (pid).
On-GPU-Time profiles for CUDA
We’ll show off a sneak peek of a feature that’s coming soon: GPU time profiles. These show the time taken on the GPU for each CUDA kernel, as well as a flame graph of the associated CPU stack traces that led to their launch.
This allows engineers working on GPU-bound workflows to easily identify at a glance which kernels they should focus their optimization efforts on for maximum impact.
In the coming weeks, we will blog about this new feature in more detail. Stay tuned!
