10. HepNT - January 15, 1997 : PCSF Frederic Hemmer IT/PDP 10 Key Issues n FORTRAN Compiler, CERNLIB & Physics codes n CODE reintegration (Physics & CERNLIB) n Stability/Predictability/Resilience n RFIO in CERNLIB n Scalability & Management n “Shell” in batch n 3rd party tools (Samba, PCAnywhere)

11. HepNT - January 15, 1997 : PCSF Frederic Hemmer IT/PDP 11 Next Steps n Install LSF 3.1 n Use FlexLM licensing n Improve resilience n Increase number of users

12. HepNT - January 15, 1997 : PCSF Frederic Hemmer IT/PDP 12 Lessons n PCSF allow us (and others) learning about NT and PC’s n Porting SHIFT software was easier than integrating adapting its build mechanism n “Unix” tools very buggy (bash, imake, ls …)  maybe avoid them n Windows is fundamentally different than Unix  think differently n … but it’s there, it’s running, so use it !

13. HepNT - January 15, 1997 : PCSF Frederic Hemmer IT/PDP 13 Other PC Farms n PCRD A testbed to study performance for future experiments farms (NA48/NA45/Compass) Windows NT and Linux n LHC Trigger Farms A testbed to enable LHC experiments to test/measure/understand/build large scale farms n PC-NA49 A Windows NT implementation of Proof (Parallel root). 5 dual 300 MHz PC’s with 23 GB each. n PC-Nomad A production farm for Nomad's reconstruction. 4 dual 266 MHz PC now, will grow to 10.
