I tried to send the config.log ... but it seems to be too big, and the message bouces back. Anyway, I've discovered that configure searches for and does not find it. Installing valgrind-devel solves the problem ... but I didn't need it before (I mean I didn't need it before Open MPI 1.4.2). Bes

What is the output of ompi_info | grep memchecker? Can you also send the stdout from OMPI's configure where it is checking for valgrind compatibility? It should be fairly obvious, probably deep in the middle of the output of configure. Here's what mine looks like: +++ Configuring MCA framewor

Hi Michele, You may actually need to have gdb/valgrind installed before configuring and building OpenMPI with the --enable-memchecker option. Regards, Eloi On Tuesday 22 June 2010 10:44:16 Michele De Stefano wrote: > Good morning. > > I'm experiencing some problems with Open MPI 1.4.2, built

[OMPI users] Problems with memchecker in version 1.4.2

Good morning. I'm experiencing some problems with Open MPI 1.4.2, built on a CentOS 5.5, on a 32 bit machine. I've configured it with ./configure --prefix=/usr/local/openmpi --enable-debug --enable-memchecker --enable-heterogeneous When I run "/usr/local/openmpi/bin/mpiexec -np 3 ls", Open MPI
