upc_affinitysize function
#include <upc.h>
size_t upc_affinitysize(size_t totalsize,
size_t nbytes,
size_t threadid);
The upc_affinitysize function is a convenience function which calculates the exact size
of the local portion of the data in a shared object with affinity to threadid.
In the case of a dynamically allocated shared object, the totalsize argument
shall be nbytes*nblocks and the nbytes argument shall be nbytes,
where nblocks and nbytes are exactly as passed to upc_global_alloc or
upc_all_alloc when the object was allocated.
In the case of a statically allocated shared object with declaration:
shared [b] t d[s];the
totalsize argument shall be s * sizeof(t) and the nbytes argument
shall be b * sizeof(t). If the block size is indefinite, nbytes shall be 0.
threadid shall be a value in 0..(THREADS-1).
