I started learning GPU programming through AMDs CPU-only beta runtime for OpenCL 1.0, wrote my BSc thesis using it and inserted actual GPU runtimes somewhere halfway through writing up the actual document. It was a true testament to how awesome OpenCL is. (I still pat myself on the back...

第一章 GPU计算与OpenCL 什么是OpenCL OpenCL全称OpenComputingLanguage即开放计算语言。OpenCL为异构平台提供了一个编写程序,尤其是并行程序的开放的框架标准。OpenCL所支持的异构平台可由多核CPU、GPU或其他类型的处理器组成。OpenCL由两部分组成,一是用于编写内核程序(在OpenCL设备上运行的代码)的语言,二是定义并...
Another assembly snippet is https://github.com/RadeonOpenCompute/ROCm-OpenCL-Runtime/blob/12d926d06d36fe74876a82f8f8e1ce8ce7902728/amdocl/glibc_functions.cpp#L30 which seems to be requiring the memcpy ABI from a particular version of Glibc, with no explanation as to why that particular ...
我的计算平台有两个AGENT,分别是CPU和GPU,CPU是通用算例,有12个compute unit,对应的是6核12线程SMT。 GPU Agent信息,计算单元数量,计算最大的TENSOR维数信息,QUEUE数量,WAVE(Warpper)大小等信息: opencl支持信息 ROCm不直接支持CUDA,但是 support another GPU programming mode opencl,通过clinfo查看: /opt/rocm/op...
My OpenCL platform identifies itself as "OpenCL 2.1 AMD-APP (2671.3)", GPU as "OpenCL 1.2 AMD-APP(2671.3)" (this is strange that it also does not report OpenCL 2.1 compatibility ...), It is expected one. Currently OpenCL runtime under AMDGPU-Pro supports OpenCL 1.2 only, so it ...

Gpu不同传统cpu只拥有栈和global的内存空间,至少还引入了shared memory这种可以再程序语言中声明的,程序员控制的memory,本质上好像就是使用的硬件cache,抛转引玉,分析shared memory的变化过程。 1.amd source code #include <hip/hip_runtime.h> __global__ void kernel_func(int* input, int* output, int n...
This is set by the OpenCL runtime when the user calls an clEnqueue* function. • CL_PROFILING_COMMAND_SUBMIT - Indicates when the command is submitted to the device. For AMD GPU devices, this time is only approximately defined and is not detailed in this section. • CL_PROFILING_...
