通常认为GEMM是计算受限的算子,且当下大热的Transformer模型负载基本上都是GEMM,故GEMM测得的最优性能可以被当作GPU的实际峰值算力。从github上的CUTLASS仓库(GitHub - NVIDIA/cutlass: CUDA Templates for Linear Algebra Subroutines)克隆源码并且按照文档里的方法编译cutlass_profiler程序。使用方法见cutlass_profiler --...

I used CUDA 11.3 and NCCL 2.9.9 version ubuntu 20.04.5 server type machine and got a nccl-test results below. My CPU is "AMD EPYC 7543 32-Core" and main memory is enough I think. ./build/all_reduce_perf -b 8 -e 128M -f 2 -g 8 # nThread 1 nGpus 8 minBytes 8 maxBytes ...
Moving this code to the GPU involves handling how patches are organized. Blindly porting numerical integration operations to CUDA is simple enough as most of its algorithms are data-parallel. However, due to the focus on scalability, patches are too fine-grained to fully occupy GPUs with enough...
Multi-Instance GPU (MIG) is a new feature of the latest generation of NVIDIA GPUs, such as A100. It enables users to maximize the utilization of a single GPU by…
