---- resource needed for reprocess 10% AuAu DST data

CPU time:

1000 J/Psi + AuAu mixing

pure dreco: AuAu data (6900 events) from DongJu Kim
user time = 4.5h/6900 = 16200/6900 = 234 Sec/100evts

HPSS:
20MB/sec * 3600 = 70G/hr

Disk:

DST file size = 2G
NEvents = 2G/250kB = 8000 events per file


MicorDST size: (from Jason Newby)

v03_DST_31058-0001.root => 1.8GBytes
uDST_31058-0001.root => 11 MBytes

Total Runs for AuAu:
911 runs / 13910 files

After MUID shield in: 29978
BField On runs = 391
Total files = 8046

golden runs = 196
goden files = ???

10% x391 = 40 runs
10%x 8046 = 800 files

--------- 10% AuAu project ---------------
CPU Time = 800 x 4.5 h = 3600 hr = 1.5 days with 100 CPUs

DISK:
- DST: 2G*800 = 1600 G 
- microDST: 11MB * 800 = 9 G

HPSS:
500G/day -> 3 days


----------- J/Psi expectation ---

MB AuAu events = 800files x 7k = 5.6 M

JPsi X  = 3.0 ub  for pp

Nbinary = 200 for AuAu M.B. collisions

total J/Psi = (3ub/30mb)*Nbin*5.6x10^6 events
            = 1.0x10^5 

BR(J/Psi->mumu) = 6%

s-muon acceptance: 8%

eff = 0.7x0.8x0.4 = 0.2
 
Total J/Psi detected = 100
