Today
Upgrade Analysis Farm
Today
- Upgrade MonteCarlo Farm has been moved June 15th from Caspur to INFN (Rome)
The Analysis Farm is still at Caspur. Contract expires in November.
Caspur is relocating this fall.
Move the analysis farm to CNAF (Bologna)
The farm can remain for a while in Rome until CNAF is ready
