Debugging an offload application


I am trying to offload a function but I get the following error:

offload error: process on the device 0 was terminated by signal 11 (SIGSEGV)

Searching on the forum I found that there is no official support for debugging offload applications without using Eclipse (which I cannot use) but most of the related topics are not really recent. 

What would be a suggested way to debug my code?

Thank you in advance,

Single-Root Input/Output Virtualization (SR-IOV) with Linux* Containers

This paper is a result of a joint CERN openlab-Intel research activity with the aim to investigate whether Linux Containers can be used together with SR-IOV in conjunction and complementary to the existing virtualization infrastructure in the CERN Data Centre. This solution could be potentially applied to the storage nodes, which are principally used for Input/Output operations, while keeping the CPU mostly idle. CERN could benefit from LXC/SR-IOV by running both CPU-intensive and storage jobs in containers on one storage node, with full separation of both applications and control over consumed resources.

  • Asyncronous offload takes more time than expected

    Hi all,

    Here is a tricky issue i seem to be facing.

    The use of the signal for asynchronous offload is defined in intel website as "both asynchronous data copy and compute".

    That means the directive below must asynchronously copy and compute data.

        !dir$ offload begin target(mic:0)out(WORK4,WORK3,WORK,WORKF)signal(2)
        call my_state_advt(TRCR(:,:,:,1),TRCR(:,:,:,2),&
        !dir$ end offload

    Compiling source code for phi processor on remote machine


    I have a server machine(every machine we have is RHEL) which the Intel Parallel Studio XE 2015 is installed on. I also have a co-processor on a different machine, and I would like to compile my codes for the co-processor on my machine. I can compile using the intel compiler just fine, but I get this error when I build it on my machine.

    icpc: warning #10362: Environment configuration problem encountered.  Please check for proper MPSS installation and environment setup.

    MIC nic user login issue

    I've configured NIS in my cluster setup. and user root of the host and head node can loging into MIC without password. But when a user is trying to login from the host to mic it asks password. after giving password it goes through. Home directory is mounted properly. nad user can loging from head node to Host node without password.
