My sysadmin used official IBM Spectrum packages to install MPI, so It's
quite strange that there are some components missing (pami). Any help?

/a.out a b "c d"
Argument parsing doesn't work well. Arguments passed are:
a b c d
and not
a b "c d"
I think there is an issue in parsing the arguments invoking Totalview. Is
this a bug into mpirun or i need to do it in other way?
Thanks in forward.

The problem is how mpirun scan input parameters when Totalview is invoked.

btl = ^tcp
btl_tcp_if_exclude = eth0,ib0,ib1
oob_tcp_include = eth1,lo

The same using other Bcast algorithm. Disabling dynamic rules, it works
