在NVIDIA Triton编译器中,properties["max_num_regs"]和properties["max_threads_per_sm"]这两个属性都与 GPU 的资源限制有关,它们关系到每个Streaming Multiprocessor(SM)能够有效支持的线程数量。以下是它们的定义和相互关系: 1.properties["max_num_regs"] 含义:max_num_regs是每个 SM 的寄存器总数,表示在每个...
BLOCK_SIZE = triton.next_power_of_2(n_cols) # Another trick we can use is to ask the compiler to use more threads per row by # increasing the number of warps (`num_warps`) over which each row is distributed. # 另一个技巧是通过增加每行分配的线程数来要求编译器使用更多的线程块 (`n...
# MAX_NUM_THREADS represents maximum number of resident threads per multi-processor. # When we divide this number with WARP_SIZE we get maximum number of waves that can # execute on a CU (multi-processor) in parallel. MAX_NUM_THREADS = properties["max_threads_per_sm"] max_num_waves = ...

Ultimately, there are 8 streaming processors per multiprocessor. But, instructions are pipelined and thread-switching is used to hide latency. For example, going from 32 to 768 active threads per multiprocessor results in a 7x speedup for a kernel that reads, increments, and writes back to ...
max number of resident threads per SM: ? max number of registers per SM: ? limited by use of shared memory: ? What does “resident” mean? Are all threads/blocks in a kernel launch resident? Thanks. resident means all threads/block at one time on a multiprocessor. If you have more bl...
