cudaHostAlloc因为使用了page-locked memory,所以速度会更快 chap10.4 介绍了stream, cudaMemcpyAsync()可以实现异步进行数据传输,能够保证下次调用该stream时,数据传输已经完成,数据依赖关系也都是nvcc或者GPU保证的。 cudaStreamSynchronize( stream )能够保证stream中所有任务已经完成。 10.5 介绍了double stream, 把原始数...

Build DPC++ & OpenMPI internally, and remove SYCL-For-CUDA-Examples (#4) April 18, 2022 10:06 README.md DPCPP for CUDA Image This docker image provides the DPC++ compiler with CUDA backend support, and a CUDA-aware OpenMPI stack. The docker image is based on nvidia/cuda:latest, an...
编译cuda Examples 时出现错误:/bin/ld cannot find -lglut ,可以先找找是否缺少库,有时候可能是symbolic link不正确,没有链接到正确位置,导致找不到库: 其命名规则是:lib+库名(即xxx)+.so。 1、可以先看看是否存在库: ls /usr/lib64 |grep glut 2、如果不存在则安装: yum install glut-devel 安装之后...
Hi! After manually installing CUDA (see below) I have trouble linking programs that use dynamic parallelism, i. e. from the CUDA examples I can build all except the following: 0_Simple/cdpSimpleQuicksort 0_Simple/cdpS…
I am really new to the GPU programming. I just set up my Nvidia driver and installed everything about cuda. so you can assume that I installed every thing necessary. I downloaded examples provided online, for example: …
