How to read out the GPU DRAM Bandwidth with Nvidia Nsight system

[hank.fang.usa]

I am using the Nvidia Nsight Systems (nsys-ui) and profiling my application, after I capture the log,

from there, how do I get some direct reading of “CPU Read Throughput” and “CPU Write Throughput” in GB/s? more like this format here?

Hi,

It’s recommended to convert the data from MB/s to GB/s on your own.
Please let me know if we do not understand your question clearly.

Thanks.

Thank you for your response, it’s not about conversion from MB/s to GB/s, from captured nsys-ui report, I can only see information like: the duration (+10.464 us), Value: 1.0%. It’s not in a typical throughput format (MB/s or GB/s).

Hi,

Please find more info in our nsys document:
