[Gate-users] About the speed of the Gate

[张春晖]

Hello Simon:
      Thank you for your reply! When simulating our PET system, I
found that my Gate became slower and slower, Have you encountered
it？In addition, What is the meaning of  “parallelizing our
simulation”？ using the Cuda? or dividing our simulation into many
small tasks?

Looking forward to your reply, Thanks a lot!
Best.---Chunhui Zhang
