Are you sure that you have exactly the same version of Open MPI on all your nodes? On May 14, 2013, at 11:39 AM, Hayato KUNIIE wrote: > Hello I'm kuni255 > > I build bewulf type PC Cluster (Cent OS release 6.4). And I studing > about MPI.(Open MPI Ver.1.6.4) I tried

I proclaimed implicit definition of type to add 'implicit node'. And I change include 'mpif.h' to use mpi. But Unfortunately I couldn't get more information. Error occuring on only slave node is to feel uneasy. But I have no idea except this. (2013/05/15 1:11), Andrea Negri wrote: I'm not an

Problem is that comm_accept isn't thread safe in 1.6 series - we have a devel branch that might solve it, but is still under evaluation On May 14, 2013, at 11:15 AM, Damien Kick wrote: > I'm been playing with come code to try and become familiar with > MPI_Comm_accept and

[OMPI users] Unexpected behavior: MPI_Comm_accept, MPI_Comm_connect, and MPI_THREAD_MULTIPLE

I'm been playing with come code to try and become familiar with MPI_Comm_accept and MPI_Comm_connect to implement an MPI client/server. The code that I have simply sends a single MPI_INT, the client process pid, to the server and then disconnects. The code that I have works for a few test runs

I'm not an expert of MPI, but I stronly encourage you to use use mpi implicit none This can save a LOT of time in the debug. On 14 May 2013 18:00, wrote: > Send users mailing list submissions to > us...@open-mpi.org > > To subscribe or unsubscribe via the

[OMPI users] MPI_SUM is not defined on the MPI_INTEGER datatype

Hello I'm kuni255 I build bewulf type PC Cluster (Cent OS release 6.4). And I studing about MPI.(Open MPI Ver.1.6.4) I tried following sample which using MPI_REDUCE. Then, Error occured. This cluster system consist of one head node and 2 slave nodes. And sharing home directory in head node by
