Different cores on different machines.

Hi all,

I have been noticing lately that some cores are faster than others on my machine. As you have probably noticed on some of my previous posts, I am running a 2 GHz laptop, and the current work unit that I am folding is using the Amber core. Whenever I run the Amber core, I seem to only be able fold at about 120 points per day. However, I've noticed that any work units that use the GROSIMT core allow my laptop to fold at about 300 points per day.

I'm just hoping that, from now on, I get given more work units on the faster cores so that I can make contributions faster.

Just wondering out of curiosity now, what cores the rest of you find the quickest on your machines.

Cheers,
Pete.

This is as expected. All types of Gromacs work units use SSE or SSE2 optimizations to fold a little faster on some processors. Amber work units do not use SSE, and fold at speeds relative to the GHz rating of your CPU.
