[Darshan-users] Trouble building shared parallel hdf5 library on BGQ, trying to use w Darshan

[Hedges, Richard M.]

I am trying to apply Darshan to a dynamically linked executable on a BGQ system with shared parallel hdf5 library.  I have tried several Darshan versions, several hdf5 versions, and am using the gcc C and fortran compilers (with mlicc and mpif90 wrappers)

Without Darshan, the code will execute, but when set LD_PRELOAD, the code aborts.  My suspicion is that there is a problem with my hdf5 library build.

Has anyone encountered this?

Does anyone have a good (and current)recipe for building parallel hdf5 on BGQ?

Thanks,
- Richard
