   Test: XI_case2_i - upc_all_alloc
   Purpose: Check the dynamic memory allocation functions
   Type: Positive.
   How : - every thread allocate memory with upc_all_alloc
         - All the thread initialize the buffer (in an interleaved fashion)
         - All the thread read all the allocated memory
