Running speed and energy range

Hi there, I have recently found out of the existence of this tool from a paper borrowed from a friend (Popescu). The paper introduced the idea of fake linac. I was trying to locate at the time a phase space file for TB 18X (looks like it doesn't exist anywhere).
I'm an old timer, many years ago I have started MC by using EGS3 and coding in Fortran iodin seeds 🙂
I would appreciate answers to a couple questions I have and could not find answers so far. I have used the contact form on the site to begin with, but haven't heard back in a long time. Here we go:
1. How much time (roughly & typically) takes a dose calculation for a Varian TB plan (e.g. VMAT, one arc) using the patient's CT. I realize it depends on the hardware used (among other things) therefore an example of such a system would be great as part of the answer. Related to this, it'd be awesome to know if the software can take advantage of multiple cores and/or can be used with clusters.
2. Is it possible to use the same system for lower energy machine? For instance Ortho (100 kV up to 210 kV) & CBCT (50 kV - 150 kV)?
I though of asking first and then dive deeper into literature and start experimenting with the software. I'm kind of into a similar position in relation to TOPAS/Geant, trying to decide which one I should invest time and effort into mastering.
Thank you so much,
Iulian 🙂
