valgrind is indicating problems in MPICH2 when using the MPE library
by John Michael Alex Grime 15 Feb '13

15 Feb '13

Hello all, If I compile an MPI code using the "-llmpe" and "-lmpe" options to enable MPI tracing, running the resultant code through valgrind ( "mpiexec -np X valgrind --track-origins=yes ./program ..." ) produces several instances of the following type of message: ==459== Conditional jump or move depends on uninitialised value(s) ==459== at 0x10001C949: MPE_Req_wait_test (in ./program) ==459== by 0x10001D4B0: MPI_Waitall (in ./program) ==459== by 0x100047FE1: AtomShare::Reset(std::map<int, std::map<int, int, std::less<int>, std::allocator<std::pair<int const, int> > >, std::less<int>, std::allocator<std::pair<int const, std::map<int, int, std::less<int>, std::allocator<std::pair<int const, int> > > > > >&, int) (in ./program) ==459== by 0x100051DD5: test(int, char**) (in ./program) ==459== by 0x100052FED: main (in ./program) ==459== Uninitialised value was created by a stack allocation ==459== at 0x10001D53D: MPI_Waitall (in ./program) ... whereas compiling and running the same code without the "-llmpe" and "-lmpe" options does not trigger this warning. I've checked to make sure the MPI_Request arrays used in the MPI_Waitall() calls are indeed allocated and set to valid requests (from MPI_Isend() and MPI_Irecv()). Has anyone else noticed any problems with MPE using uninitialized stack variables? For what it's worth, running mpiexec -info gives: HYDRA build details: Version: 1.4.1p1 Release Date: Thu Sep 1 13:53:02 CDT 2011 CC: /usr/bin/gcc-4.2 -I/opt/local/include -pipe -O2 -arch x86_64 -L/opt/local/lib -arch x86_64 CXX: /usr/bin/g++-4.2 -I/opt/local/include -pipe -O2 -arch x86_64 -L/opt/local/lib -arch x86_64 F77: F90: Configure options: '--prefix=/opt/local' '--with-thread-package=posix' '--enable-timer-type=mach_absolute_time' '--enable-cxx' '--mandir=/opt/local/share/man' '--docdir=/opt/local/share/doc/mpich2' '--htmldir=/opt/local/share/doc/mpich2' '--includedir=/opt/local/include/mpich2' '--disable-f77' '--disable-fc' '--with-mpe' '--with-device=ch3:nemesis' 'F90FLAGS=' 'F90=' '--with-pm=hydra' '--enable-shared' '--enable-cache' '--enable-smpcoll' '--enable-base-cache' '--enable-sharedlibs=osx-gcc' 'CC=/usr/bin/gcc-4.2' 'LDFLAGS=-L/opt/local/lib -arch x86_64 -Wl,-flat_namespace' 'CPPFLAGS=-I/opt/local/include -I/opt/local/var/macports/build/_Volumes_work_mports_dports_science_mpich2/mpich2/work/mpich2-1.4.1p1/src/mpl/include -I/opt/local/var/macports/build/_Volumes_work_mports_dports_science_mpich2/mpich2/work/mpich2-1.4.1p1/src/mpl/include -I/opt/local/var/macports/build/_Volumes_work_mports_dports_science_mpich2/mpich2/work/mpich2-1.4.1p1/src/openpa/src -I/opt/local/var/macports/build/_Volumes_work_mports_dports_science_mpich2/mpich2/work/mpich2-1.4.1p1/src/openpa/src -I/opt/local/var/macports/build/_Volumes_work_mports_dports_science_mpich2/mpich2/work/mpich2-1.4.1p1/src/mpid/ch3/include -I/opt/local/var/macports/build/_Volumes_work_mports_dports_science_mpich2/mpich2/work/mpich2-1.4.1p1/src/mpid/ch3/include -I/opt/local/var/macports/build/_Volumes_work_mports_dports_science_mpich2/mpich2/work/mpich2-1.4.1p1/src/mpid/common/datatype -I/opt/local/var/macports/build/_Volumes_work_mports_dports_science_mpich2/mpich2/work/mpich2-1.4.1p1/src/mpid/common/datatype -I/opt/local/var/macports/build/_Volumes_work_mports_dports_science_mpich2/mpich2/work/mpich2-1.4.1p1/src/mpid/common/locks -I/opt/local/var/macports/build/_Volumes_work_mports_dports_science_mpich2/mpich2/work/mpich2-1.4.1p1/src/mpid/common/locks -I/opt/local/var/macports/build/_Volumes_work_mports_dports_science_mpich2/mpich2/work/mpich2-1.4.1p1/src/mpid/ch3/channels/nemesis/include -I/opt/local/var/macports/build/_Volumes_work_mports_dports_science_mpich2/mpich2/work/mpich2-1.4.1p1/src/mpid/ch3/channels/nemesis/include -I/opt/local/var/macports/build/_Volumes_work_mports_dports_science_mpich2/mpich2/work/mpich2-1.4.1p1/src/mpid/ch3/channels/nemesis/nemesis/include -I/opt/local/var/macports/build/_Volumes_work_mports_dports_science_mpich2/mpich2/work/mpich2-1.4.1p1/src/mpid/ch3/channels/nemesis/nemesis/include -I/opt/local/var/macports/build/_Volumes_work_mports_dports_science_mpich2/mpich2/work/mpich2-1.4.1p1/src/mpid/ch3/channels/nemesis/nemesis/utils/monitor -I/opt/local/var/macports/build/_Volumes_work_mports_dports_science_mpich2/mpich2/work/mpich2-1.4.1p1/src/mpid/ch3/channels/nemesis/nemesis/utils/monitor -I/opt/local/var/macports/build/_Volumes_work_mports_dports_science_mpich2/mpich2/work/mpich2-1.4.1p1/src/util/wrappers -I/opt/local/var/macports/build/_Volumes_work_mports_dports_science_mpich2/mpich2/work/mpich2-1.4.1p1/src/util/wrappers' 'FFLAGS=-pipe -O2 -m64 ' 'CFLAGS=-pipe -O2 -arch x86_64 -O2' 'CXX=/usr/bin/g++-4.2' 'CXXFLAGS=-pipe -O2 -arch x86_64 -O2' '--disable-option-checking' 'LIBS=-lpthread ' Process Manager: pmi Launchers available: ssh rsh fork slurm ll lsf sge manual persist Topology libraries available: hwloc Resource management kernels available: user slurm ll lsf sge pbs Checkpointing libraries available: Demux engines available: poll select Cheers, J.

Hello all and Jayesh, I also work with both Linux and Windows. I am currently upgrading the Linux version but my Windows version will be outdated. It is completely understandable/acceptable the limitation you have and your development priorities. I just wanted to let you know that I would like to add a "+1" request on the upgrade of the distribution of Windows version. Only few people use the Windows version or are there more people that might be also interested on this upgrade? Maybe, depending on the the number of requests, this upgrade can become more important. It's worth a shot.

Hi, Good to know MPICH is working for you. Are the hostnames of the two ec2 instances the same? If you try to use ssm/shm with 1.4.1p1 mpiexec should abort with an error message.
