| dbo:abstract |
In scientific computing, OpenBLAS is an open-source implementation of the BLAS (Basic Linear Algebra Subprograms) and LAPACK APIs with many hand-crafted optimizations for specific processor types. It is developed at the Lab of Parallel Software and Computational Science, ISCAS. OpenBLAS adds optimized implementations of linear algebra kernels for several processor architectures, including Intel Sandy Bridgeand Loongson. It claims to achieve performance comparable to the Intel MKL: this mostly holds true on the BLAS part, while the LAPACK part falls behind. On machines that support the AVX2 instruction set, OpenBLAS can achieve similar performance to MKL, but there are currently almost no open source libraries comparable to MKL on CPUs with the AVX512 instruction set. OpenBLAS is a fork of GotoBLAS2, which was created by Kazushige Goto at the Texas Advanced Computing Center. (en) OpenBLAS（オープンブラス）とは、行列演算ライブラリで、BLAS のオープンソース実装である。様々なプロセッサ向けに、手作業で最適化している。以前より定評のあった、Texas Advanced Computing Center の後藤和茂による GotoBLAS（2010年を最後に更新なし）をベースに、2011年に GotoBLAS2 1.13 から派生して開発が続けられている。 Intel Sandy Bridgeマイクロアーキテクチャ や Loongson をはじめとして様々なプロセッサ向けに最適化していて、Intel Math Kernel Library に匹敵する速度で動いていると主張している。 (ja) |
