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); }

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.
