In the event of performance loss in multiprocessing applica-
tions, perform the following procedures:
1. Ensure that only one copy of multiprocessing plug-in (for appli-
cations which use plug-ins) is installed per application.
2. Quit current multiprocessing application and relaunch application.
3. Shut down system and cold boot machine.
4. Ensure hard drive is not overly fragmented.
5. Verify correct version of MP Library is installed.
6. Reinstall System Software (v7.5.2 or later).
7. Perform a clean install of System Software.
8. Clear parameter RAM (PRAM). Perform this task by simultane-
ously pressing <COMMAND> + <OPTION> + <P> + <R> during
startup. Wait for the second bong before releasing the keys.
9. Remove and test all DIMMs by replacing one at a time. Replace
any defective DIMMs.
10. Replace nPOWER card.
Display
In the event that the system provides the correct startup
sequence but no picture is apparent on the display, perform the
following procedures:
1. Remove and test all DIMMs by replacing one at a time. Replace
any defective DIMMs.
2. Remove and test the VRAM DIMMs. (If present in the 3 slot Genesis MP)
3. Remove and test the cache DIMM. (If present in the 3 slot Genesis MP)
4. Reseat the nPOWER card, display card, and ROM SIMM (if
present).*
*It is possible that the ROM socket will not be populated (ROM
will be soldered to the motherboard) and reseating the ROM
SIMM should be disregarded.
5. Reset the CUDA Chip (see section CUDA Chip in this chapter).
6. Replace the display card.
7. Replace the motherboard.
8. Replace the nPOWER Card.
