Hi @mrzv, There is some documentation here: https://github.com/LLNL/Caliper/blob/master/doc/sphinx/calql.rst - maybe that helps. Unfortunately there's currently no OR for filtering, though. For MPI specifically you can set CALI_MPI_WHITELIST when taking the...

That works for the gotcha build, but does this have additional effects? E.g. if you want to build Caliper statically? David From: David Poliakoff Reply-To: LLNL/GOTCHA Date: Monday, July 3,...

Essentially it shouldn't fail using a default config / build on Cray. I tried it on Cori.

Thanks! Simply doing this inside `dlsym_wrapper` seems to have the same effect: ``` if (handle==RTLD_NEXT || handle==RTLD_DEFAULT) { return orig_dlsym(handle, symbol_name); } ``` However, it would have been pretty easy...

Ok, thanks for the explanation. That's more complicated than I thought! Depending on how long it takes to implement option 3, I think we should in the meantime at least...

It's possible to work around this in Caliper, but it's pretty ugly. For example, in the MPI wrapper, we create the bindings list dynamically based on what the user wants...

Hi @aaroncblack, thanks for bringing this up. Shouldn't be a problem to change the exported paths, I'll look into it.

Hi @cielling, there is currently no append option unfortunately. You can however set a Caliper attribute and use that to create a new filename for every flush. That may be...
