[mpich-discuss] Problem using MPICH 3.2 compiled with --with-device=ch3:sock

[Anatoly G]

Dear MPICH,

I downloaded a MPICH 3.2 package.

When I configure it using:
*./configure --prefix=/space/mpich3.2 --enable-error-checking=runtime
--enable-g=dbg CFLAGS=-fPIC CXXFLAGS=-fPIC FFLAGS=-fpic --enable-totalview
--enable-static --disable-f77 --disable-fc --enable-shared=no
--disable-fortran*

My test program (simple send/receive) works fine on single & multiple
computers. But each process activates "busy wait on each receive".

I'd like to get program without busy wait.

Than, I configured MPICH 3.2 with following:

*./configure
--prefix=/space/mpich3.2_no_busy_wait --enable-error-checking=runtime
--enable-g=dbg CFLAGS=-fPIC CXXFLAGS=-fPIC FFLAGS=-fpic --enable-totalview
--enable-static --disable-f77 --disable-fc --enable-shared=no
--disable-fortran --with-device=ch3:sock*

After build my test program with this mpi, my test works fine on single
computer two processes, but doesn't work on two computers (process per
computer) with same configuration.

Can you please advice?

Thank you,
Anatoly.
