speed issues with pgs-pythia

Asked by Baris Altunkaynak

Hello,

I've noticed that there is a big difference in speed when I run pythia+pgs (downloaded from Conway's webpage) on a LHE file generated by MG vs when I run pythia-pgs that comes with MG. I was wondering what might be the reason for that?

Thank you.

Hi Baris,

Since a year, we use a patch done by Junichi, wich provides a factor 10 speed-up compare to previous version PGS (which you might not have).
For pythia, I let Johan answer the potential difference in speed.

Cheers,

Olivier

Olivier,

Thank you for your response. I was worried that I was making a silly mistake but that makes sense.
