[Hallcsw] Update to the Analyzer CVS for new JLab 64bit farm machines

Hello all,

With the move at JLAb CC to exclusively use 64 bit machines on the farm,
the Analyzer needed to be slightly updated.
Steve Wood updated code in the CTP and CODA directories.
The code is :
Analyzer/CTP/thParm.c
Analyzer/CTP/thTestParse.c
Analyzer/CTP/thTestExecute.c
Analyzer/CTP/thClient.c
Analyzer/CODA/evio.c

The CVS has been updated on the main trunk.
This should be good for Baryon (E01-002), Fpi2,
Spring03 and Mduality experiments. For
experiments on branches online04, online07, gep
and sane , I have added the new versions of
the files to the branches.

When compiling the Analyzer at JLab use:
setup cernlib/2005

to set the correct CERN environmental variables.

If anyone has problems let me know, I will help.

It is probably worthwhile to make comparisons between
your present version and one compiled
on the 64bit machines before March 14.
Below is the message from the CC in case
you missed it.


                      Cheers,

                               Mark



**********************************
Jefferson Lab's experimental physics data analysis cluster has recently 
been upgraded with the FY11 Physics farm node procurement.  The new 
systems are all configured with 64-bit CentOS 5.3.

The interactive systems will gain an AMD Opteron 32-core node named 
ifarm11001 ("interactive farm, FY11 system 001") on Monday, March 7. 
The new system is currently available as ifarmltest ("interactive farm, 
linux test"), with 64GB RAM and a 1TB disk including local /scratch. 
This node is being added to the current ifarml64 pool, consisting of 
ifarml1 and ifarml6,  two 8-core hyperthreaded Nehalem systems.

The batch farm is already running 22 additional nodes, farm11001-022. 
These include 18 Nehalem 8-core hyperthreaded systems with 24GB RAM and 
1TB disk, and 4 AMD Opteron 32-core systems with 64GB RAM and 1TB disk, 
for a total of 272 additional cores.  The 32-core AMD systems are being 
configured to run multithreaded jobs, rather than 32+ single core jobs. 
  Multithreaded jobs are identified by the cpu: n tag in the job 
submission.  This addition brings the total number of 64-bit cores in 
the farm to just over 700.

With this addition the 32-bit end-of-life Fedora nodes are in the 
process of decommissioning as planned. These include the interactive 
nodes ifarml3, ifarml4, ifarml5, and the last batch of 25 dual core farm 
systems.  ifarml2, an even older system, will also be decommissioned. 
These old nodes will all be shut down on Monday March 14.
