[Gate-users] Job splitter etc. on vGate

Thu Nov 18 14:04:12 CET 2021

Hi everyone

I have a macro up and running using vGate 9.0 which imports PET and CT data to generate a dose distribution. It seems to be working fine, but only uses one CPU core (which I believe is a known "feature" of Gate). My computer has 8 cores acting as 16 logical processors and Oracle VM currently has access to 8 cores. I'm not sure if this is the full 8 physical (one logical from each core) or 4 physical (two logical from each). An obvious speeding up of the process would be to use the jobsplitter and filemerger in order to utilise more cores, but I'm not sure if this is a possibility within vGate 9.0.

In the ReadTheDocs documentation, there is a section on using job splitter etc. on a cluster but this requires additional installation, plus a "cluster aware version of Gate". My gut instinct is that vGate 9.0 isn't one of those versions but I was wondering if anyone had been successful or has any other tips on getting vGate to utilise my cpu power more effectively?

Thank you
