Gromac cores

This new gromacs core allows the use of 3dnow instead of SSE for all those with XP's that seems to run unstable with -advmethods .
Problem is that frame times went from ~7 minutes to 9.30.
without 3dnow!
25 steps = 03:14:19
with 3dnow!
25 steps = 03:44:26
Running 3DNow is still much faster than standard loops.
In the Beta forum Vijay said he will give us a flag to do that in a few days after they see if this fixes the crashing and lockup problems with Gromacs wu's on AMD cpu's.

30 minutes longer on XP procs :swear:

What kind of Intel CPU is an 'XP' ? Never heered of that one:looney:

I thought Grow-Macs was an Apple fertilizer! :confused:

hehehehe, it just might be ;)

What's up? I can't get any GROMACs core WUs. :swear:

I either get Tinkers or G@H WUs, even though I'm config'd to only get f@h and -advmethods. This sux in the middle of a gauntlet.:bang:

We're all suffering from this.

Beware the bad G@H units. You don't want the "unrecognized atom" message.
My short term workaround was to reinvoke F@H without -advmethods, get a Tinker, and then reinvoke with -advmethods on. This way, if it clears up by the time the Tinker finishes, and I happen to be on-line, I should be back to all GROMACS again.

to get rid of the G@H units :
1) stop the client,
2) FAH3Console -queueinfo
3) FAH3Console -delete #of_WU
