Escali 4.4 사용자 설명서

Section:  

-n <hostname> - Specify hostname of Scali license server

This option tells the software which host to contact to check out a license. This can also be 
manually edited by modifying the scalm_net_server parameter in
/opt/scali/etc/scalm.conf.

-l - Creates a license request to be sent to license@scali.com. Host information from the 
license server must be included in the license request.
 
Scali MPI Connect is licensed software. You need a license from Scali to be able to run an MPI 
application using the mpirun or mpimon program launcher. Usually Scali will provide a time-
limited demo license to be used for installation and system test. Then a permanent license 
request is sent to license@scali.com by the user. Scali will process the license request and reply 
with a permanent license file. This file must be installed as /opt/scali/etc/license.dat on 

the license server using the following command (as described above):
 
root# /opt/scali/sbin/smcinstall -u <licfile> 

Scali MPI Connect contains proprietary kernel mode drivers which are loaded into the kernel. 
The drivers (ScaKal, ScaDET and ScaSCI) will automatically build to fit the running kernel, 
provided that a fully configured kernel source tree is installed. This is provided by the kernel-
source RPM on SUSE and RedHat distributions, however SUSE might require some manual 
configuration.

If the automatic build process fails, the drivers must be built manually using the script
/opt/scali/libexec/rebuild_module.sh in the following way :

root# /opt/scali/libexec/rebuild_module.sh scakal <path to your linux kernel source> 

optionally : 

root# /opt/scali/libexec/rebuild_module.sh scadet <path to your linux kernel source>

if Scali MPI Connect for Direct Ethernet is installed, and :

root# /opt/scali/libexec/rebuild_module.sh ssci <path to your linux kernel source>

if Scali MPI Connect for SCI is installed. To complete the process, re-run the smcinstall script 

with the same options as previously used.

To remove Scali MPI Connect, use the script : 
 
root# /opt/scali/sbin/smcunistall

The Scali MPI Connect now uses DAT as its API to connect to drivers for different interconnects. 
In DAT terminology the drivers are called provider libraries, or dapl’s.
