1/16 of the PEs can be connected at any one time, so it takes 16
operations to complete.

Error message #14: This is the exclusive OR comparison of the data
sent over the router with the data received at the other end. 32 bits of
data were sent using one
rsend32
command. Any bit set in this word
indicates an erroneous bit in the data received.

Error message #15: This is the exclusive OR comparison of the
data fetched over the router with the data received. 32 bits of data
were fetched using one
rfetch32
command. Any bit set in this word
indicates an erroneous bit in the data received.
*
Error message #16: This is the exclusive OR comparison of the
expected flag bits with the actual flag bits set during the rsend and
the rfetch operations. The position of the bits in the word indicate
which flag is in question and when it was noted. This word does not
show the actual state of the flag bits, it only indicates which flags
were in error.
