我想知道在发布过程中在CUDA内核中执行了多少个FP32和INT32说明。有什么方法可以通过Nvidia Nsight Compute对其进行介绍？

是否有任何方法可以通过Nvidia Nsight Compute进行介绍？

对于Nsight Compute，

fp32 instructions executed:    smsp__sass_thread_inst_executed_op_fp32_pred_on.sum
integer instructions executed: smsp__sass_thread_inst_executed_op_integer_pred_on.sum

示例：

$ ncu --metrics smsp__sass_thread_inst_executed_op_fp32_pred_on.sum ./t2003
...

请注意，Nsight Compute的最新版本为较新的（计算能力7.0及更高）GPU。

Is there any way to profile it via Nvidia Nsight Compute?

For nsight compute, the relevant metrics are as follows:

fp32 instructions executed:    smsp__sass_thread_inst_executed_op_fp32_pred_on.sum
integer instructions executed: smsp__sass_thread_inst_executed_op_integer_pred_on.sum

Example:

$ ncu --metrics smsp__sass_thread_inst_executed_op_fp32_pred_on.sum ./t2003
...

Note that recent versions of Nsight Compute are intended to be used on Volta and newer (compute capability 7.0 and higher) GPUs only.
