Hi Eugene
Thank you for answering one of my original questions.
However, there seems to be a problem with the syntax.
Is it really "-mca btl btl_sm_num_fifos=some_number"?
No. Try "--mca btl_sm_num_fifos 4". Or,
% setenv OMPI_MCA_btl_sm_num_fifos 4
% ompi_info -a | grep btl_sm_num_fifos # check that things were set
correctly
% mpirun -n 4 a.out
When I grep any component starting with btl_sm I get nothing:
ompi_info --all | grep btl_sm
(No output)
I'm no guru, but I think the reason has something to do with dynamically
loaded somethings. E.g.,
% /home/eugene/ompi/bin/ompi_info --all | grep btl_sm_num_fifos
(no output)
% setenv OPAL_PREFIX /home/eugene/ompi
% set path = ( $OPAL_PREFIX/bin $path )
% ompi_info --all | grep btl_sm_num_fifos
MCA btl: parameter "btl_sm_num_fifos" (current value:
"1", data source: default value)
