Title: 2010.2 on Ubuntu
Post by: pippin on March 4, 2010, 18:18

I've run 2010.2 on Ubuntu9.10.  It seems to work fine except that it is running on only one core.  Both Ubuntu and VNL are the 64-bit version and I have Linux 2.6.31-19-generic kernel.  How can I run it on multiple cores?

Hey.

It can be controlled using environment variables. I found this section in the old manual.

The new ATK threads much more than the old one, so good luck with increasing the speed of your calculations.

Thanks!  Now it is using all cores.  Seems to run much faster than the Windows version.
