[mvapich-discuss] mvapich thread multiple problem

[Devendar Bureddy]

Hi Marcin

Can you try with simple configuration with out
 "--enable-thread-cs=per-object --enable-refcount=lock-free
--enable-handle-allocation=tls --with-atomic-primitives" to see if that
have any effect? library should support thread multiple by default.
 --enable-hybrid do not have any effect with psm interface. You can remove
that one also.
