hi,
i suspect you have not enabled the epel repo (extra packages for enterprise linux). epel is required. arnem ________________________________ Fra: Opm <opm-boun...@opm-project.org> på vegne av sindimo <sind...@gmail.com> Sendt: mandag 7. mai 2018 01.56.37 Til: Alf Birger Rustad; Arne Morten Kvarving; opm@opm-project.org Emne: Re: [Opm] OPM Flow RedHat 7 Binary Package Build with MPI Support Dear Arne and Alf, Thank you for the clarifications. I am using the below yum repo found on the OPM website when doing the installation. When installing the opm-simulators-openmpi-bin package to get the mpi binaries it fails to install with the below errors related to dependencies of trilinos. Is there another missing yum repo that I need to add to resolve these broken dependencies?

The way this is done is by first making the module command available. You achieve this by the following command: . /usr/share/Modules/init/bash Now you can query for installed modules with: module avail Lastly, you can tell it to use openmpi with: module add mpi/openmpi-x86_64 On ubuntu, you do not need to do anything. If openmpi is installed, mpirun just works.

I have updated to the latest OPM release of Flow 2018.04 and tested again on RedHat 7. I still don't see any performance improvement with the new RedHat 7 binaries as if MPI was still not working. On Ubuntu it works fine. For example I ran the Norne model once on 1 processor and once on 2 processors on the RedHat 7 machine and the Ubuntu machine (identical machines on Amazon AWS m4.2xlarge instances) and these are the timings I get: Norne on RedHat: 1 processor: 769.437 seconds 2 processors: 839.285 seconds Norne on Ubuntu: 1 processor: 889.158 seconds 2 processors: 585 seconds If I do "top" command on RedHat while job is launched on 2 processors, I can see 2 processors running. However it doesn't seem that they are running in parallel, it seems as if each process is running a separate serial copy of flow, hence the run on 2 processors is even slower than the serial run. Also a quick check using "ldd" on the flow binaries on both Ubuntu and RedHat shows that the Ubuntu executable is indeed linked to the MPI library, while the RedHat binary still doesn't show any linked MPI libraries: On Ubuntu: ubuntu@ip-172-31-15-200:~$ ldd /usr/bin/flow | grep -i mpi libmpi_cxx.so.1 => /usr/lib/libmpi_cxx.so.1 (0x00007f350423c000) libmpi.so.12 => /usr/lib/libmpi.so.12 (0x00007f3503f66000) On RedHat: [ec2-user@ip-172-31-15-201 ~]$ ldd /usr/bin/flow | grep mpi [ec2-user@ip-172-31-15-201 ~]$ [ec2-user@ip-172-31-15-201 ~]$ rpm -qa | grep opm libopm-common1-2018.04-0.x86_64 opm-upscaling-devel-2018.04-0.x86_64 opm-simulators-bin-2018.04-0.x86_64 libopm-grid1-2018.04-0.x86_64 libopm-upscaling1-2018.04-0.x86_64 libopm-simulators1-2018.04-0.x86_64 opm-upscaling-2018.04-0.x86_64 I would appreciate any help with this please to get the parallel version of Flow working on RedHat. Thank you for all of your help.

I've installed the binary packages on 2 different machines, one with RedHat 7 and the other with Ubuntu 16.04 using these instructions: https://opm-project.org/?page_id=245 The Ubuntu packages ran fine with MPI and I can see performance improvement when running some of the SPE models, however the RedHat 7 version doesn't seem to have been built with MPI support. RedHat 7 currently has native mpi package that can be easily installed by yum (based on mpich-3): sudo yum -y install mpich-devel Would someone be able please to build the Flow binaries for RedHat 7 with MPI support, or perhaps if they already exist can you please point me to where to get them? I attempted building from source code but the Flow third party library prerequisite installation seems overwhelming. If anyone already has their RedHat 7 build environment setup and would be able to help I would truly appreciate it. From the instructions on the website, it says to enable MPI support you just need to pass this option to cmake during the build “-DUSE_MPI=1” . Thank you for all of your help, I really appreciate it.
