Project abstract

Radio Network Design (RND) is a telecommunication problem which consists in covering a geographic area with radio signal using the fewer number of transmitters that cover the maximum area. Therefore, it is an important topic to solve nowadays, for example in the mobile wireless technology domain, mobile telephony,... Bio-inspired algorithms are a good choice to solve the RND problem, because this is an NP-hard optimization problem which fits bio-inspired algorithms very well. In this project it is used the PBIL (Population-Based Incremental Learning) algorithm. This is a modern algorithm, and we hope to get good results with it. PBIL is based on genetic algorithms and competitive learning (typical in neural networks).

Hello Uwe:

First of all, thanks for your interest in RND@home.

I answer your doubts:

* Is your project indented to be open?

Yes, it is an open project. This is our first experience with BOINC projects and we did not know what steps to follow in order to diffuse the project. For this reason, initially, only 7 crunchers were present.

* Have I invaded a private project?

No. Don't worry. It is not a private project.

* Do you plan to open up the forum?

Yes, we have planned several improvements in our project (including to open up the forum). We need some time (this is our first experience with BOINC).

* Is there a way to look at the results?

This is other planned improvement: the development of screensaver graphics in order to show to each cruncher his/her achievements in the RND@home project. Anyway, I attach you a scientific paper showing some of the most important scientific results of this BOINC project. This paper was published in the Spanish Conference on e-Science Grid Computing 2007, as you can see in http://webrt.ciemat.es:8000/e-science/program.html (look for "Vega&quot.

* Will you put the credits in better relation to other projects?

You have reason. We have multiplied the credits by 100. We did that because our WU are very heavy/hard (from 1 hour to 12 hours, that is, they are difficult to complete succesfully), and this is a way to give our crunchers many credits for few WUs. We have to reward their fidelity in some way. Anyway, all the crunchers in our BOINC project obtain the same benefits.

Best regards, and again, thanks for your interest in RND@home.

Miguel.-

Unfortunately I can't see the result, but I can see the granted credit in my account. They are plain absurd, even without the proper knowledge of the real runtimes. It was about 10% for the first hour, it ran 5:46:23 in clock time on my puter from start until upload and generated 12,335.37 credits, that's about 100 times the usual amount.

What the... 1 hour to 12 hours is "very heavy/hard" in comparison to WHAT? And anyway, there is no reason to multiply the credits. BOINC has always given more credits to longer workunits. Not crunching until their credit matches other projects; it's just not fair.

I just downloaded about 10 WUs on my single, modest, host, should have been about 4 hours work. But each WU downloaded looks like coming in at 72 hours! No way am I going to complete that workload. Thankfully I didn't take a full days worth ;-)

I may let one WU run for a day or so, but that's all. I run a semi-random mix of projects and don't want to be hijacked by crazy WU runtimes. Maybe that's why the credit is so high - To get some half decent credit from a tiny WU that takes days to run?

Yowza. A P4 with a RAC of over 11,000.

Hey Zombie, lets see what you can get on this. 500k rac?

I have an Account at the Project but pulled my PC's from it once I found out the Credit Situation, anybody that Processes WU's for the Project is basically Cheating knowing the Credits are completely ludicrous.

Yes it's the Project giving the Credit but everybody knows it's not right so to go and capitalize on the Credits is wrong. One of the French Team Members has put up close to 240,000 Credits from 1 8 Core PC in less than 3 days Time and other people will probably do the same trying to leapfrog ahead of people in the Stats.

All the Stats Sites need to take a stand against this Project and make an Announcement that their Stats will not be put up until the Project rectifies the Credits since they have admitted to increasing them 100 Fold.

Hi poorboy , that's why I ve put this project in NMW, because I don't want to be consider as a cheater !

So have I, along with ABC due to their 1k wu's

Would be curious to see this project here.

It's because the project administrator are cheating.

Currently many people choose their project for credit and not for the matter of the project and it's not good.

And how are you determining these facts?

I crunch one of the projects mentioned because I think it's worth doing.

The gap is due to the increase of credit on Riesel Sieve + people attract with easy credit

Hello Uwe,

Thanks for your e-mail.

We have already corrected the credit system of RND@home:
1. Since all the credits were multiplied by 100, we have divided the current credits of all our crunchers by 100.
2. We have fixed the problem. Now, the credits are not multiplied by 100, so we give credits in the same way as other BOINC projects.

Please, if it is possible for you, check all this by crunching a WU. Also, please, inform all the people that now our credit system is OK. Thanks in advance.

Another important issue. In the last days we have observed that the WUs of RND@home works very fine under Linux, but they are very slow under Windows (of course, thanks to Windows ), and for this reason, many WUs executed under Windows have problems with the deadlines. Please, if it is possible, inform all the people that in order to crunch our WUs it is better to use a Linux BOINC client (of course, if it is possible).

Best regards, and again, thanks for all your help.

Miguel.-
