Did you mean mpich-3.1.2, instead of 1.3.2? Also, if it is syntax error, could you post the error message?

Yeah, Will meant 3.1.2 (to confirm 'bigio' was first in the 3.1.2 release).

the 'bigio' failure is when an i/o request overflows an integer type. Going to be a bit of work to fix that one because the integer type array is passed to MPI_TYPE_CREATE_HINDEXED and a few other function expecting "array of pointer to ints".

OK, bigtype is fixed now and is under code review. Jeff, I cribbed mightily from your BigMPI code, so thanks for putting it on github. ==rob -- Rob Latham Mathematics and Computer Science Division Argonne National Lab, IL USA
