_Offload_shared_malloc errors

Hi,

I am trying to allocate a memory in MIC with _Cilk_shared_malloc. The following is the code, which raise some errors.

_Cilk_shared
void run(int _Cilk_shared *lTable, int _Cilk_shared *rTable, int size){
#ifdef __MIC__
        printf("Run on MIC\n");
        int i;
        for(i = 0; i < size; i++)
        {
                lTable = lTable + rTable;
        }
#else
        printf("Run on CPU\n");
#endif
}


int main(){

        int *ltable = (int *)malloc(sizeof(int) * LTABLESIZE);
        int *rtable = (int *)malloc(sizeof(int) * RTABLESIZE);

        int rows = 1024*1024*32;
        _Cilk_shared int microws = 1024*1024*32;
        micltable = _Offload_shared_malloc(sizeof(int) * rows);
        micrtable = _Offload_shared_malloc(sizeof(int) * rows);
        memcpy(micltable, ltable, rows * sizeof(int));
        memcpy(micrtable, rtable, rows * sizeof(int));

        _Cilk_offload run(micltable, micrtable, rows);
}

Errors:

Can anyone help me figure out this problem?

Thanks!

You are likely to be running out of memory.

The CIlk_shared model allows you to use only about 45% of the available memory on the card.

I was able to run your program (with some edits) on a smaller numbers of rows.
