Dear All,

We would like to announce some kind of reincarnation of VTU@Home project. Some of you may remember that project, which was created in 2006 by Aurimas Norkevičius (VGTU postgraduate student at that time). Over that time, several different applications in various fields were developed in VGTU Department of Mathematical Modelling. They have gained significant attention from BOINC volunteers. Project had almost 3.500 users, which was actually on the top of capabilities of available server. However, in late 2009 due to hard drive failure, all project data were unrecoverably lost… and we had no technical and human resources to continue.

However, after two years, we have decided to recreate our BOINC project. We believe that in volunteer computing there is a place for true Olympic principles and spirit, and so we hope to find a place for our small academic project among the others. We start with cryptographic applications and hope to find scientists from our university and other Lithuanian academic institutions interested in solving their problems using this computational platform. In any case we believe that our project can contribute to popularization of ideas of volunteer computing in VGTU community.

At this point, we would like to thank the users of VTU@Home for their contribution and apologize for the possibly lost work due to hardware crash. Old project’s database is lost. Therefore we do not announce the return of VTU@Home, but the start of “VGTU project@Home”. Furthermore, this project name indicates correctly the name of hosting institution, which was changed some time ago.

With best regards,
The Project Team.

Hi,

I've read the description of your application which says "This application is solving DES Challenge problem", I was wondering what's the difference between what your doing now and what has been done in the late 90? DES is now obsolete so are you working with one of its derivatives?

Hi, nice to see you back. Just thought I'd mention that your joining url still states http://boinc.vgtu.lt/vtuathome/. ie vtuathome!

We start with classical DES, as is stated in the description. But it is just a first target, which we use to develop our tools and to see, whether we will collect computing capabilities exceeding our cluster. Next, we intend to move further to study other encryption standards.

Yes. We had hot internal discussions whether we should keep the project’s name and project’s url. Some of them are reflected in the news above. We hoped that keeping that url will help our previous users to find us. We were getting regular e-mails about the state of the project during all this two years.

May be this was a mistake to keep this url… I will look at the feedback.

Doing computation on something that has already been done might not be the best choice to create the envy of participating in your project and so really appreciate the computing capabilities that lies in BOINC. You say you want to see if it's going to exceed the computing capabilities of your cluster, some might fear that if the result isn't conclusive enough you might not continue the project and therefore they have participated for nothing. Making tests on an other encryption standard (still used or under research), no one asks for an application that works perfectly from the beginning of the project, in my point of view, would be something better for appeciating the real potencial of BOINC.

Keeping the url is confusing some stats sites. I had 10k+ in vtu@home and now that total has been reset to what I have in this one. Or, at least it has at All Project Stats.

Trust me in this; even if you don't want to be found, there are crunchers that will find you.

I'd suggest changing the URL ASAP, before too many stats sites pick it up and potentially get confused. I think only allprojectstats has picked it up so far, and apparently that's reset the old project stats :(

I've recommended the project to Free-DC and Neil's Mundayweb site, but with a note about the URL being the same. I'm sure they'll be able to work around it, but if you change the URL now nobody will get confused!

Oh, you needn't have worried about people finding you, many of us go to great lengths to keep track of 'dead' projects and find new ones. You can run, but you can't hide :)

Cheers,

Al.

BOINCstats had no problems with same URL, they preserved points and record of OLD project and added new project separately. Example here.

I think, it was good decision to use OLD url in this project and I think, admins of some stats websites can solve this problem as it solved Willy from BOINCstats.

We (Free-DC) still have all your old totals here
http://stats.free-dc.org/stats.php?page=proj&proj=vtu
why Not just start from there
Are all your old supporters that unimportant to you that you just delete them ?

Free-DC is now carrying the correct stats without losing the old project stats.

I guess you might as well leave it as it is :)

The Data was lost but not the account of the people that produced it
And with this point reset we all have lost millions of points from our combined totals
Again I implore you not to reset but to restore the total and go forward from there

The stats sites still have the old totals, so nobody has lost any credit. The old VTU is just an archived project, the new VGTU is a new project. Check out your stats at Free-DC, you'll still have your old credit :)

On the bright side, it's a new project, with that 'new project smell'. Plenty of the little milestones to pick up :)

Cheers,

Al.

Maybe this will sound selfish and unprofessional, but I don’t see the easy way to restore the user’s accounts with the VTU@Home credits from BOINC stats sites. How will we get registration passwords?

Assign VTU@Home credits only upon new registration at “VGTU project@Home”? Well, painful, but possible. But what about the users who will never register again?

So the preferable solution for us would be for BOINC stats sites to keep VTU@Home statistics (to preserve credit totals for all previous users), set VTU@Home status as permanently retired, and register “VGTU project@Home” as a new project.

Automatic reset is definitely our fault. However, I don’t know whether it’s reasonable to change the url now, because as I see some of the BOINC stats sites managed to solve the issue. Please, inform us about the problems with the stats sites. We will try to contact their admins directly.

Regards,
V.

Well, I agree with all your points. We honestly try not to mislead or create false expectations. It is small academic project with no direct funding. It is difficult to expect world changing / life saving discoveries from it. We want the volunteers to understand that and use their time on other projects if they don’t like it.

At the moment the goals are more educational and promotional. We want to present the project and ideas of BOINC computing to our students and scientists, hoping to find students interested in doing some projects with BOINC, scientists interested in porting or developing their applications for BOINC. At least some of them may join volunteer computing community and contribute to major BOINC projects.

And going back to the current application, we wanted to start with application, which raises the awareness of important problem and which we would hopefully be able to solve… Although we will not change the world and break any Olympic record with it. :-)

Regards,
V.

I see you have a GPU link •Top GPU models*
Are you working toward that

That is a new "stock" stat. Nothing to do with the apps offered.

Yes, many things changed in 2 years without VTU project. Now BOINC is full compatible with most NVIDIA and ATI GPU models, also GPU computing is at least 10x faster as CPU. Maybe You planning to build GPU application in future?

I know, many work, lack of knowledge and human resources, but...
