Charm++ parallel programming system

Hi Pavanakumar,

Can you provide more details on compilation issues that you are facing in building HDF5 with AMPI? I just tried building HDF5 with AMPI and could see some of the issues that you might have encountered; however, with some tweaks to the build script/Makefile of HDF5, I think one can build HDF5 with AMPI. 

At the very least, I will mention that AMPI ships with a version of ROMIO that can be built by passing 

--with-romio as a build flag. I just checked in a fix to handle a scenario that was earlier preventing this flag from being effective.

Hi

1) I am porting one of our in-house CFD solver (MPI based) to AMPI. 

2) The solver uses a single network mounted file for mesh and solution data

3) The individual MPI process (based on local decomposition information) read/write to this single file in parallel.

4) I am unable to successfully compile HDF5 library (v1.8.10-p1) using AMPI and hence cannot use the HDF5 file I/O

Can someone suggest a work around ?

Regards,
