[Gate-users] What is the advantage of the cluster tools and ROOT file size

[Varsha Viswanath]

Hello GATE users,

I am a new GATE user working on PET simulations and I wanted to know what
the advantage of the cluster tools are, and whether they are worth
installing. I am currently running multiple GATE runs on the cluster (1 or
2 runs per core) but after about 12 - 18 hours, I have the issue where all
instances of GATE are trying to write at the same time (similar to the
issue described here:
http://gate-users.healthgrid.narkive.com/j9rEt4LS/gate-on-cluster). The
site does include a very useful command, but I wanted to know if the job
splitter coordinates when multiple instances of GATE are running and when
they're writing so it doesn't overload the cluster - which is the issue I
run into now.

In addition, I also notice that writing to my root files after they become
somewhat large gets slower and slower. Is there a way to define a maximum
file size in GATE?

Thank you!
Varsha
