Intel xeon phi ubuntu

Is there any way to make this card work on some publkick distributions like ubuntu or debian? 

I am a bioinformatic scientist, i dont know that much about programming, and each guides i found on the web failed. 

Is there any (easy) way to make this card work on the latest ubuntu LTS? 

MPI: polling 'passive' rma operations


lately I'm wondering if your implementation of the passive target communication was ever really ment for usage...

Despite the fact that it isn't really passive (since one has to call some mpi functions on the target to get the mpi_win_unlock ever to return), I couldn't even figure out which mpi functions exactly must/can be invoked to achieve the flushing. In the release notes is only written:

Can't attach Debug Engine for Intel MIC architecture

Hi, all:

I want to debug Intel Xeon phi application on VS2012, and I follow the file below:

But when I want to attach to process, it always fail.

Can anyone tell me what wrong is it?

Getting Started with the MPI Performance Snapshot

The MPI Performance Snapshot (MPS) is a scalable lightweight performance tool for MPI applications. It collects a variety of MPI application statistics (such as communication, activity, and load balance) and presents it in an easy-to-read format. The tool is not available separately but is provided as part of the Intel® Trace Analyzer and Collector installation.  This article will serve as a quick getting started guide.

  • Profiler for loops that make good candidates for offload.

    Hi all,

    I am running an application known as CESM.

    I tried various profiler Intel(itac and also Vtune) and non intel(TAU and others).

    However I have not found any suitable profiler which can suggest loops that make for good candidates for offload or vectorization.

    the --profile-loops options do not run on parallel application and CESM takes eternity to complete if I try to run it as MPI-serial.

    Any suggestions?

    thanks in advance.

    How to change mac address of each mic device?

    I'm using MPSS 3.4.3 on windows.
    I challenged to change  mac address of each mic device by modification of "micN.xml".
    But, it failed.

    I tried following step.
    1, Modify mac address term of "micN.xml".
    2, micctrl -r
    3, micctrl --start
    ( I also tried PC reboot. )

    How to change mac address of each mic device?


    Intel MPI, perhost, and SLURM: Can I override SLURM?


    (Note: I'm also asking this on the slurm-dev list.)

    I'm hoping you can help me with a question. Namely, I'm on a cluster that uses SLURM and lets say I ask for 2 28-core Haswell nodes to run interactively and I get them. Great, so my environment now has things like:


    Now, let's run a simple HelloWorld on, say, 48 processors (and pipe through sort to see things a bit better):
