The geometry is a pencil beam impacting a sheet of material and a sheet of material as a detector. The energy is around 30keV.

I had noticed, from using intel's Vtune that there was a considerable amount of time spent in the SetSeed method. I attach a summary of the results from Vtune before and after your suggestion.

After applying your suggestion the performance for 1 billion events was

CPU: 24 minutes

MIC: 19 minutes

Is there any place in documentation that is relevant to this problem that you would recommend?

Is the method


related to this? After noticing the time spend in the SetSeed I tried to use this but it did not improve the runtime.

Many thanks for your help.
