Hi Sainath,

The UPC spec states that M has to be a compile time constant if you
declare the array statically.  You should be able to accomplish this via
dynamic allocation using upc_all_alloc(N*M, M*sizeof(int)).  The first
parameter gives the number of blocks and the second, the block size.
Also, upc_all_alloc is collective.

Good luck,
 ~Jim.
