Let me know when you have something that I can benchmark. I am eager
<br>
to see how the perf improves.<br>
<br>
I have put lmsensors on the dual Athlon and the I will try to heat them
up<br>
a bit to see if indicated temperatures make sense.<br>
<br>
<br>

Great, I noticed that you had been busy. I want to take that machine
up the the RH 3.0 ES
preview, but I will hold off until you are done/or get another machine
online so as not to interrupt
your work.When you have working binaries and/or beta test code, I would
like make it available
on our site for general download. I can give you access to a specific
directory to dump files.
Let me know when you have something you want me to test.
What were the problems you were having with Athlons. I have been trying
to run
benchmarks on the Dual MP ( fury ) and the case has been dying randomly
around
7000-8000 timesteps. This case used to work fine so I am assuming that
there may be
a library/hardware issue.
Regards
Mike

<pre wrap="">Hi Mike,
I just wanted to let you know that I've started to write x86-64
specific assembly loops - it's way easier than I first thought to
translate them.
I don't think the 64bit performance is going to be significantly higher
than 32bit compatibility mode(since the opteron isn't really emulating
32bits, but running it natively), but it will enable native compiles
and much larger systems.
It will appear in Gromacs 4 in a month or two...
I still haven't had time to check the problems we've had with previous
athlons, but I'll try to start that the next week...
Cheers,
Erik
