NCSA - Monte Carlo Run

[Bernhard Lauss <lauss@berkeley.edu>]

Dear Peter,

What is the status of your NCSA accounts and granted CPU time?
Can we run the 10^9 events from GEANT Monte Carlo there ?

Estimate for  1x10^9 events

Time:	   4000 CPU hours

Necessary Storage Space:

Intermediate for input/output processing of files

total of 2000 files each 500 k events =  6.5 TByte


after processing we can keep the GEANT output, and  gzip it
which will result in = 1.1 TByte  needed permanent storage space
+
the midas data files = 0.3 TByte  permanent storage space.

As I will leave for 2 weeks holidays on Aug.20, it would
be great if we can start such a production before that.

The production would be pure mu-p events with an
average mu_p diffusion speed now 0.26 cm / us
or any more precise value after your simulation.

The GEANT code is ready to do that.
Running of 45 CPUs for 2 weeks would do the job,
assuming getting on average 25% of the CPU time.

I will also check together with Fred to run on the PSI cluster.

			Best regards

				Bernhard
