概要 SASS とは何か?SASSについて知って何の役に立つのかについて。 SASS とは何か PTXのさらに後ろにあるほぼネイティブアセンブリ。 PTX を ptxas に入れると、NVIDIA GPU用の機械語を含むcubinが出るが、 この cubin をcuobjdumpを使って逆アセンブルした結果として確認できる。 asfermi という非公式のツールを使えば SASS->cubin へのアセンブルもできる SASS が何の略かは公式にはわからないが、Shader ASSembly ではないかとの説が。 SASS の歴史(というほど大したものではないが) cuobjdump 以前 人が頑張って機械語を解析して、独自に作った decuda というツールがあった。 このdecudaを活用して書かれた "Micro-benchmarking the GT200" は全CUDAプログラマ

ViennaCL is a free open-source linear algebra library for computations on many-core architectures (GPUs, MIC) and multi-core CPUs. The library is written in C++ and supports CUDA, OpenCL, and OpenMP (including switches at runtime). The highlights of the latest 1.7.x release family are: Fast sparse matrix-matrix multiplications, outperforming CUBLAS and MKL.Fine-grained parallel algebraic multigrid

New: The I/O engine is now available! We have partially released the source code used in this work. You can find the user-level packet I/O engine for Intel 82598/82599 NICs here. We do not have a definite release plan for other parts of the PacketShader code not made available on the web as of today. What is PacketShader? PacketShader is a high-performance PC-based software router platform that ac

httpv://www.youtube.com/watch?v=t8bxkdpJ-NU In this video, Nvidia’s Ian Buck talks about how the Cuda parallel computing platform turned 5 years old recently. He also describes OpenACC, a new open parallel programming standard designed to enable the millions of scientific and technical programmers to easily take advantage of the transformative power of heterogeneous CPU/GPU computing systems. Reco

CUDPP is the CUDA Data Parallel Primitives Library. CUDPP is a library of data-parallel algorithm primitives such as parallel prefix-sum (“scan”), parallel sort and parallel reduction. Primitives such as these are important building blocks for a wide variety of data-parallel algorithms, including sorting, stream compaction, and building data structures such as trees and summed-area tables.
