Fortran OpenMP on Intel Xeon Phi

 

My questions are very simple. We have intel visual fortran 2015 and fortran subroutines parallelized with OpenMP directives. Is the compiled code be capable of using all the available threads on the Intel Xeon Phi? Would it be required to modify the code to make it compliant with these new processors?

Our intention is to use already-parallelized code on Intel Xeon Phi or a similar MIC processor. Any suggestions or links on how to do this?

Thanks,

Supplied binary does not match the Intel(R) Xeon Phi(TM) coprocessor that is installed.

I've been using an Intel Xeon Phi A3102 coprocessor with no issues for about 9 months now, but I recently started having issues running code natively on the device. When attempting to run a program via micnativeloadex I get the error message "Supplied binary does not match the Intel(R) Xeon Phi(TM) coprocessor that is installed", which I've never seen before. I updated the software on my (composer, etc) which does not seem to have solved the problem. For reference, I'm using RHEL 6.6. Some system information collected with micinfo:

MPSS 3.5.1, Centos 7.1 x86_64-k1om-linux-ld: relocation error

Updated my mmic system to Centos 7.1, and when trying to compile hello_world with

ifort -mmic hello_world.f90 -o hello_world.f90

get a link error:

x86_64-k1om-linux-ld: relocation error: /usr/lib64/libc.so.6: symbol _dl_starting_up, version GLIBC_PRIVATE not defined in file ld-linux-x86-64.so.2 with link time reference

Any suggestions?

 

Thanks!

How to achieve an Intel® Cluster Ready Certification with Intel® Cluster Checker v3.0 on a Cluster using Mellanox InfiniBand HCAs

This article describes the steps that are necessary to achieve an Intel® Cluster Ready Certification using Intel® Cluster Checker v3.0 on a cluster using the Mellanox InfiniBand cluster interconnect.
For general information about the Intel Cluster Ready certification instructions, please refer to the Intel Cluster Ready Certification Instructions with Intel Cluster Checker v3.0 document.

  • How to handle mismatched InfiniBand HCA and switch speed with Intel® Cluster Checker v3.0

    Intel® Cluster Checker v3.0 can detect the type of the InfiniBand Host Channel Adapter (HCA) that is installed in a cluster node. It can also determine what the expected performance for a given HCA is and use that performance to compare measured performance values with.

    Intel® Cluster Checker v3.0 does not have the ability to detect the InfiniBand switch type and can, therefore, not determine what the maximum possible performance of the overall InfiniBand fabric can be.

  • How to achieve an Intel® Cluster Ready Certification with Intel® Cluster Checker v3.0 on clusters with non-identical configuration of head and compute nodes

    This article describes the steps that are necessary to achieve an Intel® Cluster Ready Certification using Intel® Cluster Checker v3.0 on a cluster where the head node and compute nodes are using different hardware or software configurations. The compute nodes use identical hardware and software configurations. A separate article describes how to handle heterogeneous clusters, where the configuration of the compute nodes differs.

  • How do I get ITAC to show routine names from my code?

    By default ITAC only displays "MPI" and "APPLICATION" in the event display.

     

    • I've set VT_PCTRACE, but that only seems to allow me to pop up a source dialog, and even that does not show a back trace so that's fairly useless.
    • I put VT_initialize/VT_finalize in my code, and create a bunch of state handles which as pass to VT_begin / VT_end.

    None to any avail. What am I missing? What file should contain my routine names?

     

    Victor.

  • Trying to make MPI work in a QuickWin application

    Hi,

    This is my first try to enter MPI into a simple QuickWin program under Visual Studio 2010

    I first installed Cluster Studio 2015 update 4 on my i7 4910MQ Dell laptop as an x64 project. The simple code compiled, linked and run directly.

    Then I just added INCLUDE *mpif.h' on a new line after the IMPLICIT NONE line and got the compiler message error #5102 cannot open include file

    'mpif.h'.

    I then tried a number of ways to inform the compiler about the location of the mpif.h file but instead got a number of warnings and errors.
