The new BOINC project μFluids is attracting some interest in the DC community so its time to create a forum thread for it.

Come and join us and make sure you grab an account at www.ufluids.net ASAP as the initial account limit is 100 participants and there are only 18 spots remaining (at time of writing).

The AMD Users team account for you to join is here:

Signed up. I'm account # 95. So 5 more spots I assume.

How's long are the WUs?

EDIT: Found this on the Distributed Computing site:


μFluids a BOINC-based science project, will simulate "two-phase fluid behavior in microgravity and microfluidics problems" in order to "design better satellite propellant management devices and address two-phase flow in microchannel and MEMS devices." The project is currently in a pre-alpha stage, but work units are often available and participants can contribute useful results. The project is limiting its total participants to 100 until the project software is upgraded some time in January.

The project uses the BOINC computing platform to run various applications. See the BOINC platform information for the latest version of the BOINC client. Version 4.01 of the project's evolver software application is available for Windows as of September 19, 2005. Note that this version of the client does not update the progress indicator. The next release of the client, which should be available in the next few weeks, will update the progress indicator. Note also that a single work unit can take anywhere from 30 minutes to several days to complete, with an average completion time of 8 hours. The client currently does not support the BOINC suspend/resume function, but may in a future release. If you have to exit the BOINC manager, or if your computer shuts down, while BOINC is processing a uFluids work unit, BOINC will restart the work unit at the beginning. The client is currently only available for Windows, but the project owners will develop a Linux client in the near future, followed by a Mac OSX client.

I don't care about completion time, but the restarting of WU when BOINC is suspended is what I don't like. While I signed up, I think I'll wait for a bit before attaching.

Those big ones were tests they were doing some time ago. They ended up being canceled by the project admin because few people could finish them.
Got some workunits here that took between 1 and 3 hours only.

I guess they haven't fully perfected the workunits yet, but at least it's only one in many.

And Robert implemented what I had asked about in the project forums. A limit in case the workunits go on and on indefinetly! Your workunit shut itself down after 50800 seconds of cpu work.

In uFluids forum they have begin to secure members. They doesn’t respect what I have written and I think we could do the same. Implement our logo as other have done or paste and qute a link to our website.

To all Teams!

It isn’t fair play to use this forum to secure members. Fair play is when all are respecting this. Members can be secured on your own homepage!

The new application with progress percentage showing was already launched and there's plenty of work for it. I haven't seen it yet because I still have a handfull of workunits of the old application to crunch.

Also, I noticed we got a quiet member crunching uFluids with us. :)

I have 2 WUs whish have a limit set to 11.47.30 on my AMD 3200+ and 2 limited to 11.59. But I will see if it takes this time or if the task will be longer or shorter. Sometimes a limit is set but the task is done earlier if there not is any fault on my eyes.
I ran a benchmark yesterday because I don´t receive a work. The server got new information.

Measured Floating Point Speed: 2.032.53 million ops/ sec.
Measured Integer Speed: 3.867.97 million ops/sec.

I think this Benchmark should be a little better yet if I should close ZoneAlarm and Panda antivirus program.

I´m surpriced that Vaughan´s Intel need 48 hour. Thank God I have an AMD. There we can se the differense between Intel and AMDs arcitecture and philosophy.

I should watch uFluids ”Top participants” and check after WU´s as I have done and these who was pending. I found 8 tasks worth 460 points who was pending. I have computer-id 24. I have run 40 tasks so far.
Clicked on computer-id to see whish other was running the same task. There was other, one with computer-ID 11. Clicked on this a new page opened and the owner is Jeffrey Robinson. He has done 428 work units. How the hell has he done that I think. Clicking on that number a page opened who show all his 428 works had erroded out as far he begins to crunch them. No points there. He have run the same work unit as me whish now is pending. In the stats page that guy have 3.697.15 in “Total credits” and 70.71 in “Recent average credits”. It is a little smaller than me and Vaughan together! I wonder where/how he has got all credits. All 428 WU´s, use zero CPU-usage.
I also noticed computer-ID 27 had got more points for the same WU as me:
Computer-ID 24: Claimed credits=94.91, Granted credits=94.91 CPU-time=27.480.91
Computer-ID 27: Claimed credits=142.59, Granted credits=94.91, CPU-time=31.436.53.

Have he got better claimed credits because he have crunch this WU longer than me?
I think he has over clocked his CPU because of higher Integer speed. But this seems not to be to any advantage because he use longer time to crunch this WU.

I don’t know how they calculate the points but it seems not to be fair. It should be much better if we all got the same points and not need to wait for other to done the same work units. If any stop runs this project any can lose CPU-hours to no use. If I run a task and got say 100 points immediately and the other 100 if they should run the task to the end.

Have you any comments to above?

The computer id 11 problem was already reported in the uFluids forums, and a few others like it were also found. It's not a problem for us if they turn back errors on the workunits because the boinc scheduler resends that same workunit to someone else.
And the differences in claimed credit for more or less equal machines sometimes have to do with different boinc versions. I heard that boinc v5 claims more credits per workunit than v4. In this project it could be good for us to use boinc v5, as the lowest claimed credit seems to always be the chosen value for granting. If we claim more, we got a better chance to get more.

Hello

I’ve been busy but now I have time to write a message about uFluid. It has been a little silent and I wish to ask which as actually running this project every day or 7/24. I am running this project day and night all days and only this project on a dedicated computer. I don’t chare this computer between other projects because it should decrease the results. uFluid is hard enough to run when a WU´s takes 6-7 hours. If I should chare this between another WU I should fall back in the rank and our team too. There is enough hard concurrence.

There are some members as seems as they first have been crunching uFluid for a little while but lather disappeared from it.

Actually of 11 participants there are Vaughan, I myself, NeoGen, Mihost, Havayoth (another Swede and participant) and Ototero, as have joined this project and make a contribution to our results as no 4 in Teams stats. We have an average of 760.87 points and our complete points are 17.814.98 in this time when I’m writing this message.
Our nearest concurrent is The Mannings who is 3.621.96 points far from us. They are only 3 participants there. But, what happen if they got 5 more?

I think it is good to keep uFluid running more or less so we can hold our rank. Until now all in the team have done great results so long all have crunched the WU´s.
How about our members as joined after the 100 first participants: Have they never got a work unit :?:

Cheers

I have not been running it 24/7 lately. I've been having some stability issues on windows, which is bad because this project can't make suspend/resume.
So I've been making batches of 4 or 5 workunits and then a pause to reboot, check the machine, and make a few other works on it, and the next day I get another half dozen workunits and let it crunch for a couple of days again.

Still we are doing very well at this project, given our small number of participants. Very good to see us up there and fighting! We probably can't win dedicated teams like boinc synergy, but we sure can put up a fight! :)

I'd like to help but I have a few personal gauntlets underway:

1. Chaz has his farm crunching Seventeen or Bust again.

2. Bruce has his farm crunching DPAD / Muon1 again.

3. DMMc is keeping me honest in eOn still. One day 72CJ5 and AMDave will threaten in eOn too looking at current production rates.

4. I'd like to lift my ranks in several other BOINC projects such as Einstein where 59th is not good enough, LHC where Heitor is pushing me, PrimeGrid where NeoGen is lonely way out in front and so deserves waking up, Sztaki where there is too much gap between me and Empty_5oul.

5. In Non BOINC I want to improve in WCG where my old friend Kamaleigh (from Entropia Fight AIDS at Home) has broken into the team top 100 and yet I trail at 115th.

I had a nasty shock the other day when I noticed I lost a million DIMES points. Stats corrected over the next few days but it made me check that every PC possible was running this critter.

I have now analysed all contributors in our team in uFluids. There are 4 who are active of 17 members. Me, NeoGen, AMD-USR_JL (1 AMD 64x2 Dual Core 4800+) and guatzacoalt (1 AMD 3500+) The 2 last is new to this project. Guatzacoalt had added a computer more (A MAC powerbook 5.9, OP Darwin) but this computer isn’t active. I don’t know why, if this computer is too weak for this job.

I wonder where all the other who join this project are? SETI.Germany has only 2.779.36 points to catch us and they are 34 members there. What is your option? Will we accept a 7th rank? I myself have fallen apart to 20th rank totally and it is difficult to hold that rank. I can see other get higher claimed points for same WU. I don’t know why it is so. Is this depending of which version of Boinc I have? I use not a optimised one.

I wish to thank our new members for their contribution :D

I think it is that they used an optimised client.

Lagu I just sent in 2 work units. One took 17 hours and the other 12 hours 20 minutes. This is on an hyperthreaded P4 3.2GHz which is also running SOB.

BOINC sees the P4 as having 2 cpus so allows two work units to run.

The P4 shares 50% cpu on SOB and 25% each on the BOINC work units.

Do you know if there is any progress on either Checkpointing or Suspend/Resume work in uFluids?

In uFluid are we 12 members with together 27 computers joined but only one is active and who is this person: Yes me. Why add so many computers and not use these? One thing is clear: We will be stomped today and go from 6th to 7th rank. It is scandal! Newer can I be happy, only sad. Is the word “fail” unknown for all?
We can talk we will add a computer or help crunch but when it is seriously where are all at that time? I think everyone may stop a moment and think about the consequences. I will ask everyone: Will we be satisfied when we lose a rank? Yes, I know there are more important projects and we have too little power. uFluid is not as important as other projects?

I apologise for my words, but something is wrong when we from time to time fail. And I’m a spontaneous person who can express both joy and grief. I will always be glad when other is glad but it is not always so easy and smile every day.

It should be grateful if we together could pull yourselves together. I hope all will understand what I really mean so there not will be any misunderstood.

Thank you for signing up. Be care to pause the WU because it begin from start again. If you need to stop the WU, wait to it have begin to crunch and then pause it. If you only have chrunch 1 minutes it is ideally for a restart. Don´t forgit to click on "No more job". Otherwise a new WU will be downloaded and chrunched.
