See the CUDA C Programming Guide for more information." PTX ISA Version 6.3 update info 开始支持整数的wmma Support for sm_75 target architecture. The wmma instructions are extended to support multiplicand matrices of type .s8, .u8, .s4, .u4, .b1 and accumulator matrices of type .s32. ...
instructions are usually translated into one or more actual SASS hardware instructions. SASS is hardcore assembly. It is what the GPU actually runs and is directly translated into machine code. Viewing SASS code is more difficult but it does show exactly what the GPU will do. As mentioned, ...
There is no constraint letter for 8-bit wide PTX registers. PTX instructions types accepting 8-bit wide typespermit operands to be wider than the instruction-type size. Example: __device__voidcopy_u8(char* in,char* out) {intd; asm("ld.u8 %0, [%1];":"=r"(d) :"l"(in)); *...
