[Gate-users] gate on cluster: speedup

[G Tom]

Hi all,
I just had a question about running gate on a cluster.
I used gjs to split my simulation into 40 macros. I was simulating 1e8
particles for a radiotherapy application.
Now I thought the 40 jobs will each run 1e8/40 particles but  I am seeing
instead that each is running 1e8 macros ?

 I took a look at the simulations
statistics output and indeed each job runs 1e8 particles:

==============
# NumberOfRun    = 1
# NumberOfEvents = 100000000
# NumberOfTracks = 1754799115
# NumberOfSteps  = 5139294665
# NumberOfGeometricalSteps  = 330040574
# NumberOfPhysicalSteps     = 4809254091
# ElapsedTime           = 69568.3
# ElapsedTimeWoInit     = 69559.5
# StartDate             = Wed May 10 00:20:45 2017
# EndDate               = Wed May 10 19:40:14 2017
# StartSimulationTime        = 0
# StopSimulationTime         = 1
# CurrentSimulationTime      = 1.2
# VirtualStartSimulationTime = 0.2
# VirtualStopSimulationTime  = 0.225
# ElapsedSimulationTime      = 1
# PPS (Primary per sec)      = 1437.62
# TPS (Track per sec)        = 25227.3
# SPS (Step per sec)         = 73883.4


examples of split macro files are :
..
/gate/application/setTotalNumberOfPrimaries 1e8
/gate/random/setEngineSeed 1683838443918737612
/gate/application/setTimeStart 0. s
/gate/application/addSlice     1. s
/gate/application/startDAQCluster 0.975 1 0 s

.....
/gate/application/setTotalNumberOfPrimaries 1e8
/gate/random/setEngineSeed 313149272728410404
/gate/application/setTimeStart 0. s
/gate/application/addSlice     1. s
/gate/application/startDAQCluster 0.95 0.975 0 s


I am not sure I fully understand how to obtain speedup by actually
splitting the
number of simulated particles using gjs,

Thanks
