Clpeak: OpenCL Device Profiling On Linux

Comment On This Article

Clpeak is a relatively new open-source tool for querying the peak capabilities of OpenCL devices under Linux.

Clpeak is a tool to profile OpenCL devices to find their peak capabilities, such as the global memory bandwidth, single-precision compute, double-precision compute, and transfer bandwidth. The device works with the binary NVIDIA/AMD drivers as well as the open-source Gallium3D Clover stack and the ARM OpenCL Linux drivers.

The clpeak code is released into the public domain. The code has actually been in development for a few months and is hosted on GitHub. The code is just being brought up now since it's on its way to landing within Fedora Linux. Per this blog post, clpeak builds are within updates-testing right now on Fedora 20 and newer. The clinfo command is also already present in Fedora for displaying OpenCL device/driver information.

The new packages are part of the plans for Fedora 21 to ship great open-source OpenCL support within this next major Fedora Linux release, which will include shipping the Gallium3D-based "Clover" state tracker, Intel Beignet, and other open-source OpenCL code that's ready in time for the F21 debut late in the year.
