Hi all 

I've set the nessecary LSF environment variable in the login scripts: 

  /brahms/u/brahmlib/etc/brahms.login 
  /brahms/u/brahmlib/etc/brahms.profile 

I highly recommend that you source the appropiate script in your
~/.login or ~/.profile on RCF.  

CSH, TCSH or similar 

  # Uncomment if you want to use the `new' software tree 
  # setenv BRAHMS_NEW 1
  if ( -f /brahms/u/brahmlib/etc/brahms.login ) \ 
    source brahms/u/brahmlib/etc/brahms.login 

SH, BASH, or similar 

  # Uncomment if you want to use the `new' software tree 
  # export BRAHMS_NEW=1
  if test -f /brahms/u/brahmlib/etc/brahms.login ; then 
    . brahms/u/brahmlib/etc/brahms.profile
  fi 

About LSF:  LSF is a system that allows you to submit batch jobs to
the CAS Linux farm.  For example, you can have a shell script like 


  prompt% cat myanalysis.sh 
  #!/bin/sh 
  #BSUB -J myanalysis
  run=$1
  bratmain MyAnalysis.C -r $run \
	     -i ~/data/rdo/run00$run.root 
	     -o ~/data/analysis/run00$run.root 
	     -H ~/data/analysis/hist00$run.root 
	     -v 5 

which you can use to submit batch jobs to the farm, like 

  prompt% bsub -q brahms_cas myanalysis.sh <runno>

Your analysis job will then be executed on some machine in the CAS
cluster, and an email will be sent to you on complesion.  See also
man(1) pages 

  bsub(1), bqueues(1), bjobs(1), bkill(1), and bhosts(1) 

as well as the documentation on the web [1].  There's a `Quickstart'
guide too [2], and an overview page [3]. 

The advantage of using LSF, is that you don't have to care for which
machines has a high load - that is done for you by the load balancing
software of LSF.  You could in principle sink data files from HPSS
onto local disk, and then process these as you see fit.
