Macro Gate
particles
10 jobs
20 jobs
We have tested the computing times on EGEE sites
(CCIN2P3 Lyon and LPC Clermont).
We divided a long simulation in a series of 10, 20, 50 and 100 simulations on multiple processors
50 jobs
Computing times are compared to user time
of initial GATE job
100 jobs
the jobs are submitted in sequential way, which implies an important launching time for a wide distribution of GATE job

24. Total Computing times of a set 100 jobs over a period of 22 days
CE_LPC Clermont
OpenGATE meeting, Grid tutorial,

25. Discussion
The computing time is not proportional with the number of jobs running in parallel. This is in part due to three parameters:
the launching time of the jobs,
the numbers of machines on the CE
CE load and performance
the RB managing of the jobs
Evolution of GATE evaluation on different infrastructures
GATE is now installed on:
EGEE nodes: LPC (France), CC-IN2P3 (France), CNB (Spain) & HG-01-GRNET (Greece)
CINES: SGI Origin 3800 (768 proc.), IBM SP Power 3 (452 proc.) & IBM P1600 Power 4+ (256 proc.)
IDRIS: IBM Regatta Power 4 ( X 384 proc.)
OpenGATE meeting, Grid tutorial,

26. Conclusion
The computing grids give promising results and meet a definite need:
reach acceptable computing time for a future use of GATE simulations for
treatment planning in brachytherapy and radiotherapy
Successful deployment of GATE on EGEE
Significant impact on computing time
These figures are good due to the fact clusters are in production mode
submission and repatriation times are very important using sequential submission (need to use multithreaded submission)
Test performance are ongoing at CINES and IDRIS sites
