Troubleshooting HOWTO: Bad hardware? MPSS? Configuration?

Are you having problems with your hardware (Cannot see your Intel(R) Xeon Phi(tm) coprocessor?  Sporadic accessibility?) or with the Intel(R) Manycore Platform Software Stack (Intel(R) MPSS) running reliably?

Attached to this post are PDF "flowcharts" that explain how you can troubleshoot the problem (note:  Both Linux and Windows flowcharts are available), and shows what information you will want to collect if you need to escalate your issue to your OEM provider or Intel.

What collateral/documentation do you want to see?

Do you have questions that you are not finding the answers for in our documentation?  Need more training, source code examples, on what specifically?   Help us understand what's missing so that we can make sure we develop documentation you care about (what is important, and what is nice to have)!   Thank you

FAQS: Compilers, Libraries, Performance, Profiling and Optimization.

In the period prior to the launch of Intel® Xeon Phi™ coprocessor, Intel collected questions from developers who had been involved in pilot testing. This document contains some of the most common questions asked. Additional information and Best-Known-Methods for the Intel Xeon Phi coprocessor can be found here.

The Intel® Compiler reference guides can be found at:

Advanced Computer Concepts For The (Not So) Common Chef: Terminology Pt 1

Before we start, I will use the next two blogs to clear up some terminology. If you are familiar with these concepts, I give you permission to jump to the next section.  I suggest any software readers still check out the other blog about threads. There is a lot of confusion, even among us software professionals.

something wrong with the offload out?

when I us offload like this

#pragma offload target(mic:0)           \
out(curdata2:length(1000)alloc_if(0)free_if(0))
{
        gettimeofday(&tv,NULL);
        L2 = tv.tv_sec*1000*1000 + tv.tv_usec;

                sleep(1);

        gettimeofday(&tv,NULL);
        L2couple = tv.tv_sec*1000*1000 + tv.tv_usec;
}

there will be an error report below:

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

and sometime the error report will be another different one
