Its README describes a full BLAS level 1, 2, and 3 implementation that generates and enqueues optimized OpenCL kernels while leaving OpenCL state management under user control. ### Project history The repository changelog carries AMD copyright from 2013 and records version 1.0 as the initial release, initially Linux64-only. Version 1.10 in April 2013 expanded level-1 coverage and tested against AMD APP SDK and runtime driver versions. The modern README says the repository houses the OpenCL BLAS portion of clMath and that APPML 1.12 was the current generally available pre-packaged binary release for Linux and Windows. A January 2017 update note identifies v2.12 as a bugfix rollup from the develop branch. ### Adoption history clBLAS became a packaged OpenCL numerical library for developers targeting heterogeneous computing before vendor-neutral GPU math stacks consolidated. The batch metadata lists Homebrew, MacPorts, Nix, Ubuntu, and openSUSE packaging, with related client/development package names. Its upstream release train appears to have slowed after the 2.12 bugfix rollup, but the package remains historically important as one of the recognizable OpenCL BLAS implementations available through Unix package managers. ### How it is used Developers use clBLAS by creating OpenCL contexts, queues, and buffers, calling clblasSetup, invoking BLAS routines such as clblasSgemm, waiting for events, reading buffers, and finally calling clblasTeardown. The README example shows this explicit OpenCL-buffer style. ### Why package nerds care clBLAS matters to package nerds because it packages GPU math as a shared library plus tooling in a way that depends on OpenCL ICDs, driver quality, CPU/GPU device behavior, and architecture-specific correctness. Its changelog is full of driver, GPU-family, and routine-specific caveats, the kind of details that make numerical GPU libraries unusually packaging-sensitive. ### Timeline - 2013: Version 1.0 is recorded as the initial release. - 2013: Version 1.10 is released in April with additional level-1 routines. - 2017: Version 2.12 is described as a bugfix rollup from the develop branch. - 2017: v2.12 tags are present in the official Git repository. ### Related projects - clMath is the broader AMD library family named by the README. - OpenCL is the compute API used directly by clBLAS callers. - Netlib BLAS is the routine model referenced by the README. - clMAGMA appears in the changelog as a test/compatibility consumer. - CLBlast is a later tunable OpenCL BLAS library that explicitly compares itself with clBLAS. ### Sources - - - ## Security Notes library-like package without higher-risk signals. - **Geiger risk:** green / low -
