nsight-compute - 如何使用 nv-nsight-cu-cli 查找 gld_throughput 和 gst_throughput

Question

无法让它工作，文档阅读起来有点棘手。
在下面尝试并将输出视为 n/a。

使用 Nsight Compute 工具更改了名称。

此表有助于获得新名称：https ://docs.nvidia.com/nsight-compute/2019.5/NsightComputeCli/index.html#nvprof-metric-comparison

使用以下 cmd 使其工作。

nv-nsight-cu-cli --metrics l1tex__t_bytes_pipe_lsu_mem_global_op_ld.sum.per_second,l1tex__t_sectors_pipe_lsu_mem_global_op_ld.sum,l1tex__t_bytes_pipe_lsu_mem_global_op_st.sum.per_second,l1tex__t_sectors_pipe_lsu_mem_global_op_st.sum, ./<program>
