Running applications (I)
• Ion Kinetic Transport (ISDEP)
Following independent particle orbits
in a fixed plasma background.
(106 orbits=jobs)x10 - 20 min
Based on gLite scripts.
Random parameters for every orbit.
No matter if some jobs are missed
• Massive Ray Tracing (MaRaTra).
Simulating microwave beams by rays (105 rays=jobs) x 40 min
No jobs can be lost. Gridway is used to distribute the jobs.
