[OMPI users] Double free or corruption with OpenMPI 2.0
Hello, I am using OpenMPI 2.0.0 with a computational fluid dynamics software and I am encountering a series of errors when running this with mpirun. This is my lscpu output CPU(s):4 On-line CPU(s) list: 0-3 Thread(s) per core:2 Core(s) per socket:2 Socket(s): 1 and I am running OpenMPI's mpirun in the following way mpirun -np 4 cfd_software and I get double free or corruption every single time. I have two questions - 1) I am unable to capture the standard error that mpirun throws in a file How can I go about capturing the standard error of mpirun ? 2) Has this error i.e. double free or corruption been reported by others ? Is there a Is a bug fix available ? Regards, Ashwin. ___ users mailing list users@lists.open-mpi.org https://rfd.newmexicoconsortium.org/mailman/listinfo/users

Also when I try to build and run a make check I get these errors - Am I clear to proceed or is my installation broken ?

Re: [OMPI users] Double free or corruption with OpenMPI 2.0
If you are not using external32 in datatypes code, this issue doesn't matter. I don't think most implementations support external32... Double free indicates application error. Such errors are possible but extremely rare inside of MPI libraries. The incidence of applications corrupting memory is about a million times higher than MPI libraries in my experience.

Re: [OMPI users] OMPI users] Double free or corruption with OpenMPI 2.0
Hi Can you please post your configure command line for 2.1.1 ? On which architecture are you running? x86_64 ?
