Was just looking through my PC's that doing F@H that i cannot acess through FahMon.

I noticed one (a 1800 XP 512MB PC2100) is taking ages to complete a WU, the WU is a 2381, 677 pointer. loaded up FahMon locally on it and It says it was downloaded 11th Feb and still has 4 days, 7hrs (57%)

I'm thinking that there is something ell wrong with that and i need to spend some time having a look. There is nothing else other than Zonealarm running (doing a virus scan once a week) on it.

It is on 24/7. CPU is at 36c
Is this about right or is this PC well off the mark.. any advice?

yeah it doesn't sound too far off i'm afraid - i'm thinking of switching some of my slower machines over to deadlineless WUs as they seem to really struggle with these Double Gromacs WUs and the nice big Tinker WUs will likely bring more PPD with them

might be worth a try
 
Good point, Rich. Athlon XP CPUs love Tinker core WUs. Cou can get mostly Tinkers by requesting timeless/deadlineless WUs.

After thinking about it a bit more I see this:
The benchmark is 110 ppd on a 2.8 GHz P4 with no SSE2. The AXP has no SSE2 so it sees no benefit there. It took the benchmark machine 6.16 days (677 points / 110 points/day = 6.16 days) to crunch it. That P4 a a lot faster than your 2100+ so it'll take you a lot longer to crunch it.

What ppd are you getting? How does it compare to other WUs you've gotten? Just becasue it takes a long time to crunch doesn't mean that it is a bad WU. Ask the CPDN fellows about that.

that's about 7 days for a 689 point Double Gromacs WU

It's only about halfway through that one, i'll probably wait till the next WU starts incase changing the options upsets the WU and it restarts - however I'm sure a deadlineless Tinker can give me better PPD

Major, that fahlog.txt looks just fine to me. Look through your benchmarks and tell us which projects give you the best ppd. I'm willing to bet that they'll all be Tinkers.

It doesn't seem that PC has done any tinkers, so what i do to get that PC on Tinkers?

Who on earth came up with the name "tinkers" :p

When I had my old 1200 Duron on the go (no SSE) it used to take ages to do normal Gromacs - I got about 25-30 PPD.
I switched it over to do deadlineless WUs and it was getting 75-80 PPD on Tinkers - nearly treble the output.

Stop the console (probably better let the current WU finish first since it's past halfway).
Run the console with the -configonly switch, when you get to the bit where it says "Request work units without deadlines" type yes and continue as you normally would for setup :)

Stan :)
 
Cheers BigStan,

Really need to gut it and install a better CPU & Motherboard combo. This is the slowest machine in my collection. Bit skint at the mo though

argggghhhhh - i've just seen that they've released a whole load of crappy Gromacs deadlineless WUs :(

which is about half the PPD that she's had from the 240ish point Tinker WUs before - this just plain sucks :(
edit: hers isn't set to get deadlienless work - it must have just been what was available at the time, there are still Tinkers available but if these Gromacs are new they'll likely be pushing them more than the Tinkers :mad:
