Main Memory Sharing Test
This test is launched by the BUMP and performed by all configured processors. It has a
sub-test to check the capability of all the processors to access the main memory. The
following hardware parts are checked during the process:
1. DCB ASICs
2. IONIAN ASICs
3. SSGA ASIC
4. SMC ASIC.
BUMP displays the overall test results.
Multi Resource Sharing Test
BUMP launches and manages the test results. All configured processors perform this test. It
has one sub-test, which checks the capability of all the processors to access the following
I/O resources simultaneously:
1. Main Memory
2. NVRAM
3. Async Lines.
The following hardware parts are checked during the process:
1. DCB ASICs
2. IONIAN ASICs
3. SSGA ASIC
4. SMC ASIC.
Multi Resources Full Test
This test is the hardest test performed by the machine. To be fully efficient, it must be:
•
launched on three processors at least (one of them is used as a de-synchronize
processor).
•
performed during thirty seconds at least. Its main characteristic is to perform random
accesses into main memory, with a very high implication of L1 and L2 caches.
