[Gate-users] how long I should set for ECAT HR+

[ljlubme]

Hi user,
I want to use the 'PET_Ecat_system.mac ' to run in single ring,
and set the sources as follows:
/gate/source/addSource F18CylinderSource
/gate/source/F18CylinderSource/setActivity 10000. becquerel 
/gate/source/F18CylinderSource/gps/particle e+
/gate/source/F18CylinderSource/setForcedUnstableFlag true
/gate/source/F18CylinderSource/setForcedHalfLife 6586 s
/gate/source/F18CylinderSource/gps/energytype Fluor18
/gate/source/F18CylinderSource/gps/type Volume
/gate/source/F18CylinderSource/gps/shape Cylinder
/gate/source/F18CylinderSource/gps/radius 50.0 mm
/gate/source/F18CylinderSource/gps/halfz 2.0 mm
/gate/source/F18CylinderSource/gps/angtype iso
/gate/source/F18CylinderSource/gps/mintheta 90. deg
/gate/source/F18CylinderSource/gps/maxtheta 90. deg
/gate/source/F18CylinderSource/gps/minphi 0. deg
/gate/source/F18CylinderSource/gps/minphi 360. deg
/gate/source/F18CylinderSource/gps/centre 6.5 0.0 0. cm
if I want the count up to 100000,how long I should set for 
the timeslice?
I set the timeslice to 1800s,but it seems need more than ten hours to finish all the count.My computer frequency is 3.0Ghz,is there some problem ?

Last,Is there anyone who has done the cluster computing to Gate ?
Thankyou!
