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.
* Error message #20: This is the exclusive OR comparison of the
data fetched over the router with the data received. 64 bits of data
were fetched using one
rfetch64
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 #21: This word represents bits 32–63 of the 64-bit
word discussed in message #20.
* Error message #22: 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.
