Hi Sergey,

I was able to recreate your error on two different systems I tried: my MacBook Pro with openmpi 1.5 and franklin at NERSC with Cray MPT (both with H5Part 1.6.2, HDF5 1.8.5-patch1). I wonder if it could be a bug in the SGI MPT stack, especially since the debug output you have points to ADIOI_Free? Is there anyway to open a bug report with SGI?

Hi Sergey, thanks for reported this bug, and the previous one with the testf program. I will take a look at fixing these this weekend. Mark

I am using fortran API of H5Part on HLRB-II supercomputer in Germany.

I found that H5Part fails if I have more then one processor with zero particles.

I can reproduce the error with a test case. Please find in the attachments

testfzero.F90: a test case I compile. (One can put
it in place of test/testf.F90 or modify test/
to have it as a new test case)

I compile  hdf5-1.8.5-patch1 with debug enabled and set environment variable
export HDF5_DEBUG="trace"
config.log.hdf5: logfile of hdf5 configuration

config.log.H5part: logfile of H5Part configuration

np.2: is an output of mpirun -prefix "%g: " -np 2 ./testf  (OK)
np.3: is an output of mpirun -prefix "%g: " -np 3 ./testf  (fails)

I use
> mpirun --version
MPI: 'SGI MPT 1.26  09/04/10 08:45:46'
