Error message #13: This is the number of operations before all PEs had
completed their router transfer using the 32-bit commands. Only 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.

Error message #17: This is the number of operations before all PEs had
completed their router transfer using the 64-bit commands. Only 1/16 of
the PEs can be connected at any one time, so it takes 16 operations to
complete.
Error message #18: This is the exclusive OR comparison of the data sent
over the router with the data received at the other end. 64 bits of data
were sent using one
rsend64
command. Any bit set in this word indicates
an erroneous bit in the data received. This word represents bits 0-31 of
the 64-bit word.
Error message #19: This word represents bits 32–63 of the 64-bit word
discussed in message #18.
