C-5 Install Scali MPI Connect for Infiniband
When installing for InfiniBand you must obtain a software stack from your vendor. The different
vendors provide stacks that differs. If you got a binary release, install it before SMC and give
the path to the infiniband software to the -b option to smcinstall.
Example:
root# ./smcinstall -b /opt/Infinicon
It is no problem if you install the InfiniBand software after SMC, you only need to modify
/opt/scali/etc/ScaMPI.conf to have the line:
networks = smp,ib0,tcp
and ensure that the VAPI library (libvapi.so) is in a directory listed in /etc/ld.so.conf.
If you're using the Mellanox source distribution you can give the path to the tarball directly and
smcinstall will compile, make a rpm and install it for you.
Example:
root# ./smcinstall -b /tmp/mellanox_sdk.tar.gz
C-6 Install Scali MPI Connect for SCI
To install Scali MPI Connect for SCI, please specify the -s option to smcinstall. When this option
is selected, SMC will default to SCI as the default transport device .If this is not desired, modify
the networks line in the global /opt/scali/etc/ScaMPI.conf configuration file. See “SMC
network devices” on page 12 for more information regarding network selection.
C-7 Install and configure SCI management software
This option must be used separately, and is needed when you are installing Scali MPI Connect
for SCI. It must be installed on only one node in your system, and it doesn’t have to be one of
the nodes you’re installing the other MPI software on, i.e it can be an management only node,
the only requirement is that this node must be connected and on the same TCP/IP subnet as
the others.
When using this option you are asked for the names of the other nodes in your cluster, and
also the topology of your SCI network (ring, 2D torus or 3D torus).
C-8 License options
-u <licensefile> - Install/upgrade license file and software.
If not specified during install, only the license manager software is installed. Without a license
file (license.dat), the software expects a centralized license scheme and looks for a license
server (specified in /opt/scali/etc/scalm.conf)
If smcinstall is run as:
root# /opt/scali/sbin/smcinstall -u <licfile>
the specified license file is installed and the Scali license manager software (scalm) is installed.
