一般而言:每个block里面包含的线程threads_per_block推荐值为128;所以,块的定义设计为:dim3 threads(32, 4) 也可以写成三维形式(32, 4,1)。计算时32个threads 处理一个/多个softmax计算数据。一个函数的调用,要完成batches * attn_heads * query_seq_len次softmax运算。

max_num_regs 和max_threads_per_sm 的关系可以用寄存器分配与线程数的权衡来解释。具体而言: 每个线程需要占用一定数量的寄存器。例如,如果每个线程使用了 32 个寄存器,而 max_num_regs 是65536(这是一个典型的值),则一个 SM 上能够支持的最大线程数量受到寄存器数的限制。 计算方式为: 实际最大线程数每线程...

Improved parameter block validation Localized names of ParamBlock2 (PB2) parameters are now tested to ensure they use resource ids instead of string literals. Using string literals instead of resource id generates the following error: This means that the definition for parameter 'Uuid' in ParamBlock...

With 20 registers per thread, if I only run about up to 192 threads per block, then 20 x 192 threads x 2 blocks are less than 8192 registers in a multiprocessor. So I thought a mutliprocessor will be able to run 2 blocks concurrently. With 16 mutliprocessors, total 32 blocks should ...
