Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.
Messages are "chained" if there are only replies at the first level, i.e. 1/1.html, 1/1/1.html etc. In case of "chained" messages the message number is replaced by the icon and there is no indentation.

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.
