— DECmpp Sx indirect load/store tests
Syntax
pe_memdiag [-bqt]
Description
The pe_memdiag command loads and runs a back-end program which does the
following operations:
1. Has each processor element (PE) do 1000 (hex) indirect stores followed by
1000 indirect loads; checks for error
2. Has each PE do 1000 direct loads of the same data; checks for error
3. Has each PE do 1000 indirect stores followed by 1000 inverted indirect loads;
checks for error
4. Has each PE do 1000 inverted direct loads of the the same data; checks for
error
If there are no errors, the program returns a success code and halts. If there are
errors, the program returns the following:
• Operation type (1–4 above)
• Direct address involved with the error
• GOR of indirect address involved with the error
• Operation type (Report on individual PE)
• PE number
• Indirect address
• Data received
• Data expected
The program checks all PEs and returns a separate report for each one found to
be in error.
Options
-b
Use this option to specify the burn-in test; runs the diagnostic repetitively,
reporting the error count at the end of each pass.
-t
Use this option to specify terse message style; prints only the most essential
messages.
