It seems icc or icpc does not know about the option -mp, so "mpiCC -g -O2 -mp simple_mpi.c" complains about -mp. > mpicc -g -O2 -mp simple_mpi.c cc1: error: unrecognized command line option "-mp" > mpicxx -g -O2 -mp simple_mpi.c cc1plus: error: unrecognized command line option "-mp" I used mpi

Hi Have look at the Open MPI FAQ: http://www.open-mpi.org/faq/ It gives you all the information you need to start working with your cluster. Jody On Wed, Sep 30, 2009 at 8:25 AM, ankur pachauri wrote: > dear all, > > i am new to openmpi, all that i need is to set up the cluster of around 5

Re: [OMPI users] MPI_Comm_accept()/connect() errors

Thanks for your reply. I am running MPI 2.0 on Ubuntu 4.2.4, kernel version 2.6.24. I ran the server program as mpirun -np 1 server. This program gave me the output port as 0.1.0:2000. I used this port name value as the command line argument for the client program: mpirun -np 1 client 0.1.1:

[OMPI users] Openmpi setup with intel compiler.

Hi, I have a two nodes cluster with rocks 4.3 installed on it, with an intel roll. Due to some problem in MPICH and Torque tight integration, i planned to switch to Openmpi.1.3.3. The cluster is also installed with PGI cdk. I successfully setup openmpi with PGI, but during configuring with Intel

Re: [OMPI users] how to set up the cluster of 5 nodes in openmpi

Hi All of your questions are answered in the FAQ... If you have a TCP/IP connection between your machines so that each machine can reach every other one, that will be ok. First make sure you can get access from each machine to every other one using ssh without a password. See the FAQ: http://ww

Re: [OMPI users] how to set up the cluster of 5 nodes in openmpi

Hi Ankur Pachauri Besides what Jody already said. 1) Do these machines have Internet IP addresses and, say, corresponding Ethernet interfaces that you want to use for MPI? 2) Or are you planning to establish a private network only for using OpenMPI? I would suggest using #2. Typically this ca

Re: [OMPI users] Changing location where checkpoints are saved

Thanks for the reply! Concerning the mca options for checkpointing: - are verbosity options (e.g.: crs_base_verbose) limited to 0 and 1 values ? - in priority options (e.g.: crs_blcr_priority) do lower numbers indicate higher priority ? By searching in the archives of the mailing list I found

[OMPI users] openmpi still not works

Hi folks, I am misunderstanding with OpenMPI. I cannot run jobs compiled by OpenMPI on several nodes. It is running only on the one node. But also in this case jobs are not finished sometimes. Its make output and hang. But other MPI implementations (mpich, mpich2, mvapich1, mvapich2) work pe

One thing immediately stands out - you should never -enable-progress- threads. That is an experimental option that certainly does not work at this time. On Sep 30, 2009, at 1:27 PM, worl...@ukr.net wrote: Hi folks, I am misunderstanding with OpenMPI. I cannot run jobs compiled by OpenMP
