Module mic not found in Fedora 20

I'm trying to install MPSS on Fedora 20 but I get this error when run the command " modprobe mic":

modprobe: FATAL: Module mic not found

In some forums, it is stated that this problem occurs because the present version of the kernel version is not compatible with MPSS version but I have tried different versions of MPSS including MPSS-3.3.5, MPSS-3.4.5 and MPSS-3.5.1 and none of them works. My linux version is 3.11.10-301.fc20.x86_64.

Does anybody has any idea?

Thank you

Is it possible to us Intel MPI 5.1.0.038 with TCP over ethernet?

I have just installed Intel 5.1.0.038 into a shared NFS space meant for use by my team who share four machines connected by Ethernet.  I have a machines.LINIX file listing the hostname of each machine that I saved into the NFS space.  My intention is for us to use the library over the Ethernet connection, but I am not sure that I have configured it correctly to do this.  I am not the administrator of the machines and so I do not have explicit root access.  However, I am in the sudoer group.  During the installation, I was not able to install using the "Run using sudo privileges and password

OpenMP 4 nested parallelism thread placement

I have a question to ask about some of the environment variables to get thread placement working properly on the phi with nested parallelism. I've looked around the Intel website and various other sources, and talked to some people at Intel, but I can't quite get it working properly.

Essentially, I want to run my code using only 3 threads per core (assuming 60 cores) because testing has shown that it gets the best performance. Without nested parallelism I could get 3 threads per core with these variables:

uOS Build

Hello!

During OS programming for the PHI, the need exists to permanently install RPM's.

Is there a systematic solution for determining and generating changes required to the uOS on a per RPM basis?

Seems like the process would involve an initial analysis of the RPM for contents.

Then the appropriate modifications to the PHI filelist need implemented.

Any thoughts on additional requirements?

 

 

One option that I've overlooked is to use an NFS share as the root for the PHI.

To Intel: How to run Phi 5110p with host and Cluster Studio under Windows?

Hi,

I bought a Phi 5110p and Cluster Studio under Windows in an Intel campaign in order to use MPI to feed the Phi card. Hardwarewise I understand the major issues but softwarewise it is still unclear to me what the right way forward is, Can I work with W7 or should I use some other Windows product? The reason for clinging to Windows is that I have a lot of QuckWin based graphics that keep me informed what is going on during the computations.

Performance issues with Intel MPI (RMA Put/Get) on Xeon Phi

I'm getting bad performance with MPI_Put (and MPI_Get) in IMB-RMA All_put_all microbenchmark on this system configuration:

  • Single and multiple Xeon Phi coprocessors
  • Intel MPSS 3.5.1 (June 2015), Linux
  • Intel MPI Library 5.1.0.079
  • OFED-3.12-1 or OFED-3.18-rc3 (It doesn't really matter.)

Intel MPI runtime environment variables:

Where is uninstall.sh file in the MPI 5.1 distribution?

I installed MPI 5.1.0.38 on July 16 this year, but I did not install it correctly.  I want to uninstall it, but I can't find the uninstall.sh script referenced in the Intel® MPI Library for Linux* OS Installation Guide: "To uninstall the Intel® MPI Library, go to the Intel MPI Library installation directory and run the
uninstall. sh script."  I am not sure how to uninstall the software without the script. I will appreciate any assistance in helping me find this script.

Thank you,

offload error: cannot release buffer memory on device 0 (error code 14)

I need your help. 

I tried to run K-means algorithm on Xeon Phi by using offload mode.

But when i tried to get into offload region with the clause '#pragma offload ~~ (as attached pic 1) ' ,

i got an erorr 'offload error: cannot release buffer memory on device 0 (error code 14)' .

I have no idea to solve this problem, and i even cannot find any previous example similar to my problem on google.

I saw offload report by using 'export OFFLOAD_REPORT=3', but i couldn't get any hints. 

plz help me !

regards
