Steve Wood update code in the CTP and CODA directories
so that the Analyzer can be compiled and run on the
new 64 bit JLab farm machines. The modified files are
Analyzer/CODA evio.c
Analyzer/CTP thTestParse.c
Analyzer/CTP thTestExecute.c
Analyzer/CTP thParm.c
Analyzer/CTP thClient.c
Before compiling on the JLab 64 bit machines
use command
setup cernlib/2005
to get the right cern environment variables.
When submitting jobs to the JLab farm for
now you need to have the line
OS: linux64
in the jsub file.
Below is the message from the computer center
in case you did not see 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.
