A100 no metrics

[gmfricke]

Hello,

When running tau version 2.31 compiled with gcc 8.5.0 running on Rocky 8 the tau_cupti_avail command lists the expected counter when run on a compute node with a V100 GPU. On the same cluster with an identical compute node setup but with an A100 card the list of available metrics is empty.

Any advice you could provide would be much appreciated.

All the best,

Matthew

Hi Matthew, Would you please try with TAU 2.32? I am wondering if it requires sm=70 vs 80 in the compiler flags. Thanks, - Sameer

Hello,

Thank you for the reply.

We tried compiling tau 2.32 with spack and by hand and each time got

"... undefined symbol: _Z17write_sass_outputv" at runtime

We tried gcc 12 and 8.5.

2.31 compiles without issue.

All the best,

Matthew
