clpeak — "Compute Latency PEAK". A synthetic micro-benchmark that measures the peak achievable performance of GPU compute devices. It exercises tight vector / MAD / MMA loops and vendor-SDK GEMM libraries (cuBLASLt on NVIDIA, MPS on Apple) to expose what the hardware is capable of — from raw ALU peaks to near-vendor-advertised matrix throughput.
clpeak began as an OpenCL-only tool and is now a multi-backend benchmark — OpenCL, Vulkan, CUDA, ROCm/HIP, Metal, oneAPI/SYCL, plus a native CPU backend — run back-to-back on the same hardware, so cross-stack differences (driver lowering, instruction scheduling, extension exposure) surface alongside the raw peak numbers.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
If you’re running Ubuntu 16.04 LTS (Xenial Xerus) or later, including Ubuntu 18.04 LTS (Bionic Beaver) and Ubuntu 20.04 LTS (Focal Fossa), you don’t need to do anything. Snap is already installed and ready to go.
For versions of Ubuntu between 14.04 LTS (Trusty Tahr) and 15.10 (Wily Werewolf), as well as Ubuntu flavours that don’t include snap by default, snap can be installed from the Ubuntu Software Centre by searching for snapd.
Alternatively, snapd can be installed from the command line:
sudo apt update
sudo apt install snapd
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install clpeak, simply use the following command:
sudo snap install clpeak --classic
Browse and find snaps from the convenience of your desktop using the snap store snap.
