AFNI Message Board

Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

https://discuss.afni.nimh.nih.gov

Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.

Sincerely, AFNI HQ

I have run AFNI on a Xeon processor system before. It should compile and run fine. To get the best speed, you'll want to compile it yourself. You should use gcc 3.x, since that can produce faster code than gcc 2.x. You can then use some extra command line options to target the binary to the SSE instruction set on the more advanced Intel processors.

However, my experience with Xeon (3-4 years ago) was not very impressive. For the cost differential vs. Pentiums, at that time the speed improvement was marginal: 50% cost increase, 10% speed increase. What the situation is now, I have no idea.
