Check MPI Performance

(Host) This will run the ibtest mpiperf command to do a quick check of PCI
and MPI performance.
This displays the MPI latency and bandwidth between pairs of hosts (1-2, 3-4, 5-6,
etc). The results are also written to the test.res file which may be viewed via the
View ibtest result files. Refer to the section "Interpreting the ibtest log
files" on page 5-68 for more details.
The numbers reported should be checked against the practical PCI speeds in the
Performance Impact section. If any pairs are not in the expected performance range,
carefully examine the two hosts involved to verify that the PCI slot used, BIOS
settings and any motherboard jumpers related to devices on PCI buses or slot
speeds. Also verify HCA and riser cards are properly seated.
4.2.9

Generate all Hosts Problem Report Info

(Host) This will run the captureall command to collect configuration and status
information from all hosts and generate a single *.tgz file which can be sent to
the Support Representative.
4.2.10

Run a command on all hosts

(Linux) This will run the cmdall command. A Linux shell command (or sequence
of commands separated by semicolons) may be specified to be executed against
all selected hosts.
4.2.11

View ibtest result files

(All) This permits viewing of the test.log and test.res files which reflect the
results from ibtest runs (such as those for installing QuickSilver software or
rebooting all hosts per menu items above). The user is also given the option to
remove these files after viewing them.
If not removed, subsequent runs of ibtest from within the current directory will
continue to append to these files.
