Q
If any hosts fail to be updated, use the View ibtest result files option to
review the result files from the update. For more details, see “Interpreting the ibtest
log files” on page 5-68.
4.1.8
Configure IPoIB IP Address
(Host) This will run the ibtest configipoib command to create the ifcfg-ib1 files
on each host. The file will be created with a statically assigned IP address. The
IPoIB IP address for each host will be determined by the resolver (Linux host
command). If not found via the resolver, /etc/hosts on the given host will be
checked.
4.1.9
Build MPI Test Apps and Copy to Hosts
(Host) This will build the MPI sample benchmarks on the IB Management Node
and copy the resulting object files to all the hosts. This is in preparation for execution
of MPI performance tests and benchmarks in a later step.
4.1.10
Reboot Hosts
(Linux) This will run the ibtest reboot command to reboot all the selected hosts
and ensure they go down and come back up (as verified via ping over the
management network). When the hosts come back up, they will be running the IB
software installed.
4.1.11
Refresh SSH Known Hosts
(Linux) This will run the setup_ssh -C -i"" command to refresh the ssh known
hosts list on this server for the Management Network. This may be used to update
security for this host if hosts are replaced, reinstalled, renamed, or repaired.
4.1.12
Rebuild MPI Library and Tools
(Host) This will rebuild the InfiniServ MPI Library itself and related tools (such as
mpirun). This will be performed via the dobuild tool supplied with the InfiniServ MPI
Source. Consult the QuickSilver Fabric Access Software Users Guide for more
information.
