Another Dist. Comp. App - Fight Cancer!

[Nuno]

Just a question: I cannot finish my working unit, because every time I turn off UD agent, it restarts at 98%, 6h27m cpu time. Last time it was at ~9h cpu time, and I lost it. That didn´t hapenned before, it resarted at he point is was turned off...

Why?

[Pneumatic]

It restarts at the beginning of the molecule that it was working on when you shut down. Last time you shut down you may have been at the beginning of a molecule so you didn't realize that it started over. Some of the molecules take more "conformers" than others, so it varies on the time that they take to finish. I had one molecule that froze me at 15% for 12 hours. It had over 500 Million conformers. If I had shut it down at 499,999,999 conformers, it would have started at the beginning of that molecule when I restarted and I would have lost 12 hours of work.

The best bet is to wait untill you have a relatively low number of conformers to restart. I usually feel ok about restarting if I am at less than 1 million. If I look and I have 50 Million I wait till it gets done with that molecule.

good points everybody i tried using just mux as the site name but homestead already had another site named that and I just didnt think of it when i listed it at UD ....oops , i am working on the site and will be putting up the links tonight, that darn sitebuilder crashed my comp when i choose to install it on my own comp so im doing it online
and it does seem to go faster when you just leave it alone because im coming up on 13 hours and it was stuck on 11 for 3 of those hours im at 95% now so in the morning i guess
go for it kindness we need people!!

Hey...

I have G@H and UD running at the same time it takes a bit longer for G@H to run and it slows down UD maybe 60%... but I still have them both running.. if I can get more systems for G@H I will run UD exclusively on this system...

Oh and Staples here near when I live had 256MB of PC133 SDRAM for 100 Bucks Canadian (About 65 Dollars American I think)

I went to pick some up but they were sold out.. they are supposed to get more soon.. but I couldn't reserve any...

Oh well.. I have a nice new printer (HP 842C) not the greatest but only 30 Dollars more than it would have cost me to replace all the cartidges for my old Canon BJC 4300 and it came with a set of cartidges...

OK that works.

Windigo, I think that you should put the goal of the UD Agent on the front page. If we direct people there they won't know what the program does and they shouldn't have to go figure it out. Here is the way they describe it on their website:

-----------------------------------------------------
"Download the UD Agent and truly be a part of a world-changing project. The National Foundation for Cancer Research (NFCR) Centre for Drug Discovery in the Department of Chemistry at the University of Oxford, England, is working with United Devices and our Member Community in the search for new drugs in the treatment of cancer. Don't just make a donation. Make a difference.

Volunteer Your PC
By combining thousands of ordinary PCs to work on extremely large computational projects, problems can be solved more quickly and less expensively than by conventional methods. Now regular people can help fuel research and projects that previously may have required a bank of supercomputers or a hundred years to complete. Plus, they can help the Make-A-Wish Foundation and have the chance of winning great prizes."
-----------------------------------------------------

The site looks GREAT. You obviously have a talent for that stuff (I envy that).
Take it for what it's worth, just a suggestion.

[windigo]

excellent suggestion LOL i totally forgot!! i got so busy making the site i forgot what it was for hehehe ill do that right away

Great work Windogo.

I just joined up.

Device info:

Overall: 26
Processor: 30 Intel P3-450
Memory: 34 128 Mb
Storage: 30 1.00 GB
Network: 17 Dial-Up Adapter, Realt... (What does this mean?) I'm on a 384/128 ADSL line. It's not Dial-up, it's "always-on".

How's about you other member post your device info for comparison.

Regards,

Jake

[Jake]

Where I heard about you?

I read the boards sometimes....

And thank you for welcoming me. It's nice to be "onboard".

One question: If you reboot or shut down he comp while it is working on a task, does it restart? The reason I ask is, that I had to reboot at 20% and now it does not seem to increase any more, like it did earlier today. It has stayed at 20% for 4 hours now...

Let's fight the cancer! (Cough! Where did I leave my zigies?)

Well, I just uploaded my second result, and my network jumped from 5 to 1753, giving 601 as overall. Anyone better?

For hd, I just talked it up to 9,77 GB. Since the hd is larger than this, it should have used 10GB.

I don't understand that 3 MB hd-usage and 12-16 KB downloaded has to do with the systems performance. This is 0,03% hd, and worst-case 0,1% of the time to network.

Apart from this, the "points" is also based on "cpu-time". Now, since UD uses run-time, this can really screw up the points.

UD's other problems is this:
Don't work alongside seti@home or genome@home. The only way to get UD to do anything is set the priority to "real".
Uses only one cpu in multi-cpu. Can't run multiple instances of UD.
No caching of wu/results.
Needs 800x600 screen-resolution to work correctly.
Auto-updates executable every time getting wu.

It saves the current status after every molecule.
Since one mulecule can have anything from a couple of conformers to over 500 millions, you should check before exiting the status. You should not exit if it's above 10 millions, and especially above 100 millions. Then it re-starts, it then must re-do the 10 or 100 millions it's already done in the molecule.

My wee bit of input

Is noone else worried about Erik's post?

I'd prefer a different group name too! Is it possible to change?

Cool site - but would you want to integrate them?

And unless anyone disagrees, Matrox Users Resource Centre has a much nicer acronym than Matrox Users Group! It's bad enough having a few mates going on about LUGs, without being becoming a bloke in a MUG!

From what I have read, each molecule is actually represented by one percentage point. You get 100 molecules per work unit. However, each molecule can have many different variations and that it represented by the last 2 numbers in the molecules name. The one I am working on right now is "CGX5#33941-99". That means that it is the 99th version of the molecule. Each version of the molecule starts over at 0 conformers. I am up to 184,500,000 conformers on this version of the molecule. If I were to restart now, I would not only lose that 184 million conformers but all of the ones that were in the other versions of this molecule since it starts over at the beginning of the molecule you were working on when you shut down.

This whole scenario is why you will seem to get stuck at a percentage for hours at a time. It just means that you had a molecule with many different versions and many conformers per version.

So, actually you need to look at more than just the conformer count. You also need to look at what version of the molecule you are on. If you only have 10,000 conformers, but your on the 79th version of the molecule you may lose a lot of work since the 50th version may have had 1 Billion conformers.

UD is working on a fix. They are going to give us the ability to save our work in the middle of a molecule so that we can restart without losing hours of work.

Hope this wasn't too confusing.

I am Pneumatic on the team board.
My sysstem has gotten as high as a 63, but right now it is down to a 52.

Processor (P3 500) = 34
Memory (128MB) = 34
Storage (10GB) = 196
Network = 68

The network is the one that fluctuates. Yesterday I was rated as 100, but today it was down. I thing that when it reports it rates your connection, so if there is a lot of net congestion it assumes you have a slower connection. Not real sure about that one though.

Welcome to the team! Glad you could join us.

BTW: How did you hear about us?

Well, that molecule finally finished at 1.1 Billion conformers!
