I believe the C compilers have sizeof(int) = sizeof(short) = sizeof(long) == 46 or 64 bits, depending on a compile time flag (Crays can do 46 bit integer arithmetic using the vectorizing floating point processors, so that is the default). Binary communications between Crays and other computers is something I haven't done, mostly because Cray doesn't support IEEE floating point.
