The second adds device timing histograms. This is useful to understand how a workload executes at a high level, across all kernels. It is especially useful to identify outliers if the execution time for some kernels varies based on kernel inputs or other factors.

The first adds conditional profiling. This is useful to restrict profiling to the specific regions of an application that you care about, while minimizing overhead and ignoring profiling data for unimportant regions. The conditional profiling is controlled by an environment variable so it can easily be used by many programming languages.

I need to get better about announcing improvements to the OpenCL Intercept Layer, so: I merged two new features this week that I think are pretty neat. As a reminder, the OpenCL Intercept Layer is an open source tool for debugging and profiling OpenCL applications. It works with most OpenCL implementations and requires no application modifications. #OpenCL

I got an Arc Pro B50 for testing, and it's really smoll. Same chip as the B580, but cut down from 2560 to 2048 cores, and the memory bus reduced from 192 to 128-bit. But VRAM is increased from 12 to 16GB. And with only 70W TDP it's super efficient and doesn't need external power. 🖖😋

Also tested 4x Arc Pro B60 24GB in mutli-GPU. 🖖🤪
