[mvapich-discuss] MVAPICH2 jobs hang up probably due to changes between, 2009-10-08 and 2009-10-28?

[Manhui Wang]

Hello,
     I built MVAPICH2 library using mvapich2-trunk-2009-10-08.tar.gz
with Intel v10 compilers last year. The following options are used:
nice -n +18 ./configure  --with-rdma=gen2
--with-ib-include=/usr/include/infiniband --with-ib-libpath=/usr/lib64
--prefix=/home/sacmw4/soft/mpich2-trunk-2009-10-08-install FC=ifort
--enable-f90 F90=ifort F77=ifort --enable-cc CC=icc --enable-cxx
CXX=icc 2>&1 | tee configure.log
nice -n +18 make 2>&1 | tee make.log
nice -n +18 make install 2>&1 | tee install.log

When I linked our Quantum Chemistry Program MOLPRO with this library,
all our testjobs worked fine and still work fine now.

I tried mvapich2-1.4 version later with the same compilers and options,
and linked it with our program as before. Some testjobs hang up. I have
built different versions of mvapich2 (mvapich2-1.2-2009-10-28.tar.gz
mvapich2-1.4.1.tgz  mvapich2-1.4-2010-04-07.tar.gz  mvapich2-1.4.tgz
 mvapich2-trunk-2009-10-08.tar.gz mvapich2-1.4-2010-01-02.tar.gz
mvapich2-1.5rc1.tgz) with the same compilers and options, and linked
them with the same program. The builds linked with
mvapich2-1.2-2009-10-28 and versions after 2009-10-28 have the same
problem (some jobs hang up). I am wondering whether there is something
wrong with the code changed between 2009-10-08 and 2009-10-28. Or have I
missed something? I have attached the compilation log files.

Thank you in advance.
Manhui
