Escali Escali, LLC Network Router 4.4 User Manual

Section:  

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 

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.

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).

-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.
