【中文标题】如何使用 nv-nsight-cu-cli 查找 gld_throughput 和 gst_throughput【英文标题】:How to find gld_throughput and gst_throughput using nv-nsight-cu-cli 【发布时间】:2020-05-01 09:13:21 【问题描述】:无法使其正常工作,并且文档阅读起来有些棘手。 在下面尝试并将输出视为 n/a。
root@teja:~/Projs/CUDA/05-Profiling# nv-nsight-cu-cli --device 0 --metrics gst_throughput,gld_throughput ./run 0

【问题讨论】:
【参考方案1】: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>
