I get the same error on a 32 bits architecture if I use the tuned
collectives.
mpirun -np 4 -mca btl tcp,self -mca coll tuned,basic
src/MPI_Allreduce_user_c
dump tons of MPITEST error (0): i=64, int value=4, expected 1
.
If I disable the tuned module:
> mpirun -np 4 -mca btl tcp,self -mca coll basic src/MPI_Allreduce_user_c
MPITEST info (0): Starting MPI_Allreduce_user() test
MPITEST_results: MPI_Allreduce_user() all tests PASSED (7076)
the test pass without errors.
