cilk runtime error

[chavhan__hitesh]

I am using MYO model for offloading my code to MIC but it I am getting some sort of runtime errors .Is this errors are code related or some system issues.

CARD--ERROR:1 _myoiPageFaultHandler: 0x44108b068 switch to default signal handle
CARD--ERROR:1 Segment Fault!
HOST--ERROR:myoiScifGetRecvId: Call recv() Header Failed ! for source: 1, errno = 104
HOST--ERROR:myoiScifSend: Call send() Failed! errno = 104
HOST--ERROR:myoiSend: Fail to send message!
HOST--ERROR:_myoiWatchdogDaemon: could not send to target: 1
offload error: process on the device 0 unexpectedly exited with code 1

It does not necessarily imply a system error. There are two examples noted below exhibiting some of the same messages where the fault was associated with variables used within the offloaded code. One example is not using the _Cilk_shared/_Cilk_offload method, one is.

If you can provide a reproducing example of your code then we would be able to help pinpoint the cause.
