Problem when running the intel optimized MP LINPACK Benchmark

Hi, I'm running  intel optimized MP LINPACK Benchmark on one node with two Intel Xeon Phi coprocessers. I use "make arch=intel64 verson=offload" to compile the code, and in bin/intel64 I use "./xhpl" to run, and it has no problem. Then I change P,Q from 1,1 to 1,16 because I have 16 cores on the node, and I change N from 1000 to 30000. Then I use "mpirun -np 16 ./xhpl" to run xhpl, but it has an error and stopped, it shows:

"Error in scif_send 104


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

I am new to Xeon Phi coding. I am getting "offload error: process on the device 0 was terminated by signal 11 (SIGSEGV)" if my array size is greater than "500000". Following is the code I am trying to run.

If I change my array size to 600000 it throws the error.

#include <iostream>
#include <omp.h>
#include <stdlib.h>
#include <sys/time.h>
#include <stdio.h>

using namespace std;

#define  MAXIMUM_VALUE   1000000

prefetch keyword misnomer?

Dear forum,

Looking at the assembly code, the prefetch intrinsics function with _MM_HINT_T2 hint is compiled to vprefetch2, which, according to MIC instruction set manual, is a non-temporal L2 prefetch. This seems to contradict the temporal nature implied in "T". Or did I miss anything?

MIC Fortran Error : could not find 'k1om-mpss-linux-ld.exe'

I am using the 64 bit Intel Visual Fortran compiler through visual studio 2013 and Windows 7 professional and am encountering an error which prevents compilation. I stepped back to the beginning Xeon Phi labs and used the provided code as a simplest case which I knew should work and the error was still present (Code used included for reference).
