[Trilinos-Users] [EXTERNAL] Re: Memory Profiling

[Frey Matthias (PSI)]

Hi Dmitry and Jason

Thanks. Yes, it works. After enabling KOKKOS_ENABLE_PROFILING and KOKKOS_ENABLE_PROFILE_LOAD_PRINT in the Trilinos
build, I could use the kokkos-tools.

Best,
Matthias

Hi,

There is a general approach for profiling memory usage by wrapping the standard *alloc/free functions using ld's wrap and/or LD_PRELOAD techniques. You can find further information in man. Kokkos' MemoryUsage is also doing something along these lines.

Kind regards,

Hi

I'd like to profile the memory usage of Tpetra. I found on the website of Kokkos

https://github.com/kokkos/kokkos-tools/wiki/MemoryUsage

that you can do memory analysis. Is this also possible in Trilinos?

Thanks,
Matthias
