For some reason the SCIF interface in my compute nodes is refusing connections. Any ideas on what's wrong or where to start investigating:

The node has a Mellanox ConnectX-3 HCA with the latest Gold Update 2 MPSS and everything else set up "by the book". All the IB services and modules load nicely and seem to work and I can ssh into the MIC and run natively.

However, if I try to run an offload (LEO or OpenCL) application it hangs. Doing an strace reveals the following:

Hello,

I am writing this test code :

#include <stdio.h>

#include "offload.h"

int main()
{
char cdir[128];
int ndevices, devnum;

getcwd(cdir,sizeof(cdir));
ndevices = _Offload_number_of_devices();
devnum = _Offload_get_device_number();
printf("\n Hello...%s %d %d \n",cdir,ndevices,devnum);
return 0;
}

and compiling 

icc -o hello hello.c -loffload

compiles succesfully

However, when i am compiling as 

icc -o hello hello.c -loffload -mmic

Dear All,

I am facing problem in using _Cilk_shared key word. It does not work for bigger arrays. The same program works well when you have small array size/data.

I am getting either the following error or an error suggesting to increase memory map area.

CARD--ERROR:1 myoiPageFaultHandler: 0x7fffff22a788 Out of Range!
CARD--ERROR:1 _myoiPageFaultHandler: 0x7fffff22a788 switch to default signal handle
CARD--ERROR:1 Segment Fault!

What can we do so that we can use _Cilk_shared with big data (larger arrays).

Thanks,

Jesmin
