pe_rtdiag
— DECmpp Sx processor element (PE) router diagnostic
Syntax
pe_rtdiag [-t]
Description
The
pe_rtdiag
command uses a back-end program controlled by an HDB script.
It performs three test routines:
•
Identity pattern: Using the router, each PE shifts data to itself
•
Multiplex pattern: Using the router, PE #0 shifts data to all PEs one at a
time
•
Demultiplex pattern: Using the router, all PEs shift data to PE #0 one at a
time
After each shift, the back-end program checks that the source T-bit is no longer
set, that the destination R-bit is set and that the correct data was received at the
destination.
If an error occurs, the HDB script prints the board, chip and cluster information
of the offending PE. It also prints the state of the applicable error bits in the HSR
and PPSW registers.
Options
-t
Use this option to specify terse message style; prints only the most essential
messages.
