Re: BOINC Points post in Member News

May I ask, how the scoring system will work when the BOINC version of HPF2 gets going again soon, when there is no quorum ? What method will be used to compare work done, if for instance a fast machine gets a very complex job and a slow machine gets a less complex job and the slow machine completes quicker than the fast one ?

I do understand why the quorum is not necessary to validate the science with HPF2 BTW.



We have not written the validation/credit granting code for HPF2 on BOINC yet. Until We do and make sure that what we are planning works then we will refrain from providing details lest those details change.

Understood. Thank you.

Re: BOINC Points post in Member News

We obviously have some rogues still getting through

Workunit Name Device Name Status Sent Time Time Due /
Return Time CPU Time (hours) Claimed/ Granted BOINC Credit
faah0895_ bdb370_ mx1ohr_ dry_ 04 p5ycho-77f4c849 Valid 11/15/2006 08:51:08 11/15/2006 15:00:35 3.30 65 / 154


This 'rogue' came thru because in fact 2 were in the quorum. The award system will take care of that in subsequent 'outlier' deductions, so that over a larger group of claims by the 'rogues' their net credit will end up substantially below the stock claimers.....they're not winning, they're loosing. As side effect, suppose carl.h had a temporary wide grin on his countenance.

Today i had same event of being a "low outlier"... my claim was excluded and got half of the 2 high claims was awarded. It will occur less and less. The noose is getting tighter.

Re: BOINC Points post in Member News

The changes were announced in the normal way.

laughing

The normal way to inform your SPONSORS (that's what we are, NOT part of your personal @home computer farm) is to send around an informative email and not post some side-remarks in some "never visited forum" (yes, I came here today for the first time after participating for > 1.5 years). This policy is ridiculous (one could say a slap in the face of your sponsors) and actually the only thing to (massively) complain about except for that I also wonder where the results of all these WCG projects have gone - the website does not seem to be informative in this respect at all (or I am too dumb to find it biggrin ).

But let me go a bit more into details with this entire credits issue, because it is an often debated topic. I am not a supporter of the optimized BOINC clients, rather I would prefer the DC project leaders to hand out fixed credits per each WU type (even this is not fair in all cases: Nano-Hive@home WUs of the same type must not necessarily "converge" to a result but in such cases the problem is solved because special credits are awarded). But here goes the story:

For a long, long time (I participate in DC projects since more than 6 years 24/7), I just used the official clients offered on the individual projects download pages - until I found out that people overtook my private >20 GHz computer farm using their single C64. biggrin I investigated the issue and found out that they were using these optimized BOINC clients. Well, since I do not give too much on credits (although sometimes it's fun to see what your machines can do while you are having a cup of coffee or two in the morning), I first kept on crunching using the standard clients (too lazy to reinstall for just the credits sake). But after a while I got a bit annoyed that stats handling became so inconsistent so I started using these clients, too. DC project leaders were not caring about the issue anyway, so why not keeping up with the others, I thought. You may therefore now call me a part-time cheater (although you never have officially set any relevant rules for participating such as not allowing modified clients that would justify such an attitude) but still I funded your research considerably for which you should rather be thankful. Instead, without a clean notice, you have adjusted your crediting system - as I understood it - such that people using the optimized clients now may get credits even lower than those they would have got using the standard clients. Are you cheating now? biggrin

And what about your cheating efforts performed on Linux users over all these years? Are you going to correct this, too? Or is this entire issue just a one-sided coin?

It is high-time that DC project leaders understand that DC participants are SPONSORS that donate a very expensive resource. We are giving it away for free but it would be nice if you guys wouldn't in return treat us as "computer cattle". biggrin

Best regards, hugs
Michael.

P.S.: Let me stress that my post is not at all about supporting optimized BOINC client usage (although for the Linux guys I would say using these is only fair) but rather the policy how contributers are treated in general.

And one more thing: If you wanted to do something REALLY useful, you would take care that your DC clients make the most of up-to-date hardware, i.e. that - where possible - your software uses certain optimizations (SSE, SSE2, SSE3, etc.) instead of hoovering around the state of the arts in programming of the year 2000. I am buying machines to EXCLUSIVELY hook them up to DC projects NOT hooking up DC projects just because I have machines and you could save your sponsor some money by just investing a bit more of your time in your own project. wink

Re: BOINC Points post in Member News

There are a few things to answer here:

Firstly, and most importantly, I want to address your last point about the relationship between WCG and their members. WCG have asked nobody to go out and buy computers. The whole idea is that grid computing uses spare capacity that already exists. It can be argued, in fact, that buying additional computers and running them 24/7 is not only uneconomical, it is also not energy efficient. So, exactly how much computer time you chose to donate, please remember that it is your decision, and WCG only ask for the capacity that would otherwise go to waste. WCG are grateful no matter how much or little you donate.

The issue of optimised clients is a complicated one, and one we have discussed at length before. The summary of the situation is this: some projects are able to optimise their science applications. Optimised clients match up with optimised science. WCG is not able to optimise the science more than the WCG grid techs already have (the code is closed source) so pairing WCG with an optimised client causes grossly inflated claims. Not just a little bit inflated - up to ten times what should be claimed. You can imagine - some people were unhappy about this.

Now, if WCG sent all updates, changes and project launches out by email, you would have floods of email from WCG. Frankly, I think WCG don't want the burden of managing a bulk email list. For every one person annoyed about missing a change without the list, a thousand would be annoyed by getting an update they didn't want. WCG compromise by announcing changes on the website, usually in the forum.

This particular change is one that made itself known fairly quickly to the kind of person that runs optimised clients 24/7 and keeps a close eye on their score. Installing the official client isn't so very burdensome.

Don't worry about the results. Academic research is a slow process, as all the facts need to be checked by many people. As a result, the results will only be published quite a few months after the project has finished running on the grid. Don't expect to see results from projects that are currently running on the grid (although there have been proposals to show work in progress).

How about expanding the 'Whats new'-section on the mainpage and adding your updates there?

Re: BOINC Points post in Member News

Firstly, and most importantly, I want to address your last point about the relationship between WCG and their members. WCG have asked nobody to go out and buy computers.

Have I said that? I know what I am doing (sometimes at least) and I buy these computers for the science sake. If you want, you can say I have made my profession a hobby by founding an officially registered association dedicated to DC together with a lot of friends. biggrin The way you answer my concerns (taking side remarks most serious and not really answering what I was talking about), indicates that you are in need of some information about your supporting community. We are not the little kids from the block that mainly like computer games (although these are well-appreciated, be the way... biggrin ). Instead we are a worldwide community of GENEROUS PEOPLE THAT KNOW VERY WELL WHAT THEY ARE DOING. It would be nice if you could simply accept that and treat us accordingly.

The whole idea is that grid computing uses spare capacity that already exists. It can be argued, in fact, that buying additional computers and running them 24/7 is not only uneconomical, it is also not energy efficient. So, exactly how much computer time you chose to donate, please remember that it is your decision, and WCG only ask for the capacity that would otherwise go to waste.

We are well aware of that. But you know, some people like to keep a dog spending a hell of money for that kind of hobby, others just set up computers to support (hopefully) useful science. It is that simple. We have an interest that you guys are successful because it is our effort, too. We have an interest, that our cycles are used most efficiently, because we pay the electricity bills. We have an interest that the data WE generate is made available to the public. That's why we are here. Because, we (the public) have generated that data. We give you the chance to put good scientific ideas into practise. We are not here because we like to check our current positions in an anyway doubtful ranking list every day. Still, it contributes to keeping the people interested by making tough science fun for those that simply cannot understand it. That's why stats are so important!
Talking about uneconomical / not energy efficient you know very well that most certainly NONE of the scientific projects currently running as DC projects would ever be put into practise if we weren't that uneconomical. The world does not spin around economics although a majority of people trys to make me believe that. wink

The issue of optimised clients is a complicated one, and one we have discussed at length before. The summary of the situation is this: some projects are able to optimise their science applications.

...others are not. That's why I said "- where possible -". biggrin

WCG is not able to optimise the science more than the WCG grid techs already have (the code is closed source)

...the rest of the sentence I could not follow, but a suggestion: Make it open source and we will see whether your claim holds true. wink

Now, if WCG sent all updates, changes and project launches out by email, you would have floods of email from WCG.

I did not ask for sending floods of email, but just one about an important topic (see above for why it is important even for those that don't really care about the stats).

This particular change is one that made itself known fairly quickly to the kind of person that runs optimized clients 24/7 and keeps a close eye on their score. Installing the official client isn't so very burdensome.

See, another one of your completely incorrect assumptions. I use the optimized client but never would have got to know about this stats change issue if a colleague had not told me. Simply because I do not have the time to keep up with such website changes of all the projects I support. And even if I would support WCG exclusively (which I will definetely not as long as it is closed source), I would not have known. I am not a stats analyzer. I just get informed as a side-effect when we are going for a fun race with another team.

Don't worry about the results.

Actually, that's all I worry about! That's what I am here for! Generating results! Somehow, you must really believe, we are just the "WCG-stats-gazer", right? Unbelievable!

Academic research is a slow process, as all the facts need to be checked by many people. As a result, the results will only be published quite a few months after the project has finished running on the grid. Don't expect to see results from projects that are currently running on the grid (although there have been proposals to show work in progress).

Well, I am a chemist and therefore I know very well what science is all about. Where are the results of the finished projects? Closed source?

hugs
Michael.

Re: BOINC Points post in Member News

Wow, you seem unhappy.

As a chemist, you will then be able to understand when I tell you that the first HPF paper is in peer review (I believe a draft is available) and the results database will be made public when the paper is published.

I'm afraid you seem to have completely missed my point about "supercrunchers" like yourself. I'm just a volunteer, like you, and I have to confess I run my computers longer and harder than I should in a good cause. But there is a point where doing so becomes uneconomical - not for the project, because they get free computeing however it is derived - but for you. Supercomputers are far more cost efficient in terms of putting together new, dedicated computing resources. So instead of buying dozens of computers, you could donate the money to charities that will spend the money on research.

I'm not telling you that this is what you ought to do, or trying to belittle what you do in any way. I'm just trying to give you some perspective.

The vast majority of WCG members (hundreds of thousands of them!) are average computer users, donating a few spare cycles. Obviously, WCG would like to do everything they can to keep the supercrunchers like yourself happy, but their main focus, and the reasoning behind their policies, must always be dictated by that silent majority.

I think what it comes down to is this: if you are going to go to the effort and expense of donating a large computing resource, you must put that little bit of extra effort in to keep yourself up to date with what is going on, and all your computing resource running smoothly. That makes perfect sense to me. There's no point in half-measures if you are going to invest so much in the project.

Lastly, the source would be open if that were possible. Sadly, the code is usually owned by some scientific institution or other, and it takes a complicated three-way legal agreement just to let WCG optimise and board it for the WCG grid. Making it open source is just too much to ask (but we live in hope).

Re: BOINC Points post in Member News

Herr Michael H.W. Weber,

Sie dürfen Ihren fruste auch auf Deutsch ausdrucken.... verstehe es wunderbar. Wenn Sie viel rechenkraft zu Verfügung haben könnten sie ein Partnerschaft eingehen. WCG hat fast dreihundert solche Verträge.

öfter übersetzt eine Fremdsprache auf Englisch etwas zu direkt, da diese Missverständnisse. Es gibt viele Kulturen im Beteiligung auf unserem Forum, aber das brauch Ich Ihnen nicht zu erklären.... 'Lost in Translation' wie mann sagt.

Grüsse und auf wiederhören

That is indeed VERY good news at least. smile

But there is a point where doing so becomes uneconomical - not for the project, because they get free computeing however it is derived - but for you. Supercomputers are far more cost efficient in terms of putting together new, dedicated computing resources. So instead of buying dozens of computers, you could donate the money to charities that will spend the money on research.

Firstly, a hobby rarely is uneconomical. biggrin Secondly, I get the feeling that you are not really employed somewhere in academics, right? If you were you would know that you will hardly receive a grant for spending it on supercomputer cycles - but maybe in America this is different...

The vast majority of WCG members (hundreds of thousands of them!) are average computer users, donating a few spare cycles. Obviously, WCG would like to do everything they can to keep the supercrunchers like yourself happy, but their main focus, and the reasoning behind their policies, must always be dictated by that silent majority.

Another misjudgement? Volunteers not active in your forum are e.g. even more active in ours. There is no such thing like "that silent majority" just because you don't hear from them. Also, if "they" were silent all the time, there would not be a need for you to act on the stats, right? Hence, a somehow inconsistent argumentation you come up with here, I think.
It is simply time - just to say it once again - that you change your attitude towards your supporting community. wink

I think what it comes down to is this: if you are going to go to the effort and expense of donating a large computing resource, you must put that little bit of extra effort in to keep yourself up to date with what is going on, and all your computing resource running smoothly.

Let me give you a small advise on what a really good DC project takes utmost care of: Never disturb the sysadmin in his/her cycles, i.e.: construct a client that after installation never requires tweaks. Else your client won't survive for long in his/her farm. laughing

Lastly, the source would be open if that were possible. Sadly, the code is usually owned by some scientific institution or other, and it takes a complicated three-way legal agreement just to let WCG optimise and board it for the WCG grid. Making it open source is just too much to ask (but we live in hope).

That's a result of American standard policy. Fortunately, this is different elsewhere...

Michael.
