problem when multiple MPI versions installed

Dear all,

I have a problem to launch processes when multiple MPI versions installed. The processes work before I installed latest MPI

C:\Program Files (x86)\Intel\MPI\>mpiexec -wdir "Z:\test" -mapall -hosts 10 n01 6 n02 6 n03 6 n04 6 n05 6 n06 6 n07 6 n08 6 n09 6 n10 6 Z:\test

However, after I installed MPI, the following errors displayed when I launch mpiexec in the environment of

Aborting: unable to connect to N01, smpd version mismatch

  • Intel MPI and Supported OS and number of cores per machine

    Has intel made a statement as to the last know good version of Red Hat that supports Intel MPI  We have a new cluster with 20 cores/per node and have observed a fortran system call failing when more than 15 core per node are used.  This machine is running Red Hat 6.6 x86_64.

    Alternatively are their known conditions where Intel MPI will fail.

    Bug Report : MPI_IRECV invalid tag problem

    Hi, there,

    In MPI_5.0.3, the MPI_TAG_UB  is set to be 1681915906.  But internally, the  upper bound is  2^29 = 536870912, as tested out by the code attached.

    Same code will run just fine in MPI 4.0.3.

    Just to let you guys know the problem.

    Hope to see the fix soon. Thanks.



    2-1. Source Code

    !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! to build path automatically

    Looks like on Linux the intel MPI runtime hardcodes the path of, eg:
    I_MPI_ROOT=/opt/intel/impi/; export I_MPI_ROOT

    On windows on the other hand the path is dynamically generated:
    SET I_MPI_ROOT=%~dp0..\..

    Is there any reason to why the path cannot also be automatically generated on Linux?

    License File Activation

    I just received my serial number of single user Intel Cluster Studio 2015 (Linux).  I had done product registration and generated a license file.  However, the license file generation page didn't show any information or steps of "how to apply the license file"...

    I am using an evaluation version of Intel Cluster Studio 2015 in Linux workstation.   So, I want to use the above license file.  I copy the license file into /opt/intel/license folder.  Do I need to execute any command?  Is there any guidelines or info.


    MPI Library Link Error

    Hi, Everyone,

    Under Linux OS, I built my MPI application with Intel MPI  There is no error in compiling but there are following error in linking MPI library.

    I am using the Intel MPI's  libmpifort.a and libmpi_mt.a for linking my application.

    LIBS          = -L/opt/intel/composer_xe_2013_sp1.2.144/mkl/lib/intel64 -lmkl_intel_lp64 \
                    -lmkl_intel_thread -lmkl_core /net/rdnas/home/dingjun/intel/impi/ /net/rdnas/home/dingjun/intel/impi/

    Using Intel® Trace Analyzer and Collector Version 9 with Intel® MPI Library Version 4

    If you are compiling your program with Intel® MPI Library Version 4 and adding the Intel® Trace Analyzer and Collector Version 9 (Initial Release or Update 1 only) at compile or link time via the -trace option, you will encounter linkage problems, similar to the following:
