MATLAB code that follows these steps might look something like this: % 1. Compile a PTX file. mexcuda -ptx myfun.cu % 2. Create CUDAKernel object. k = parallel.gpu.CUDAKernel("myfun.ptx","myfun.cu"); % 3. Set object properties. k.GridSize = [8 1]; k.ThreadBlockSize = [16 ...

右边我们举了一个Triton的例子,也是OpenAI在主推的一个跨平台编程语言。它也是通过不断地编译和语言的转化,最终在调用底层英伟达硬件的时候,通过PTX code来调用的。所以简单来说,PTX的这一层是通过和硬件的直接交互,使得可以控制硬件更多的细节。 这件事为什么重要呢?我认为它一共有两大类优化。第一大类优化是底...
This chapter explains how to create an executable kernel for a CUDA C code or PTX code and run that kernel on a GPU by calling it through MATLAB. Moreover, a brief introduction of CUDA C is presented. Furthermore, two classic examples, vector addition and matrix multiplication, are ...
fread(ptx_code, 1, ptx_size, ptx_file); ptx_code[ptx_size] = '\0'; fclose(ptx_file); // 创建CUDA上下文 cudaDeviceProp prop; int device; cudaGetDevice(&device); cudaGetDeviceProperties(&prop, device); // 创建CUDA模块和函数句柄 ...
Hi Skybuck, Thanks for your reply. I created the filter.ptx file and the main.cu file. I wrote the filter.ptx file putting inside it address_size 64. I used two comands to compile the files: nvcc -fatbin -arch=compute_20 -code=sm_20 -m=32 filter.ptx ...
PTX has an .address_size directive that specifies the address size used throughout the PTX code. The size of pointers is 32 bits on a 32-bit host or 64 bits on a 64-bit host. However, addresses of the local and shared memory spaces are always 32 bits in size. During separate ...
(JIT) at application runtime. As shown in Figure 1, the executable for an application can embed both GPU binaries (cubins) and PTX code. Embedding the PTX in the executable enables CUDA to JIT compile the PTX to the appropriate cubin at application runtime. The JIT compiler for PTX is ...
