(A Bit) Beyond B0rkley....The Wider World of BOINC


Thanks for all the positive comments about Issue 1 of the BOINC newsletter. It’s very much appreciated. I’ve decided to start Issue 2 with a quick catch up on what’s happening over at the first and mightiest of BOINC projects – Seti@Home…

Seti@Home

For a while it seemed like the whole point of SETI – Searching for Extra Terrestrial Intelligence – had been forgotten, as the team spent all their time fighting bugs and crashes in barely sufficient hardware and trying to supply the vocal hordes of rabid crunchers with enough work to keep them satisfied. I admit I became so despondant with the lack of progress on the search (or at least news of it) that I’ve directed most of my flops towards more deserving (IMO, of couse) projects.

Things have changed a bit since the new year though. There are new, more modern servers:
- sidious: Intel Server (3 x dual core 3GHz Xeon, 16 GB RAM)
- thumper: Sun Fire X4500 (2 dual-core 2.6GHz Opteron, 8 GB RAM)
- bruno: Intel Server (2 x 2.8GHz Xeon, 12 GB RAM)

Which are helping to keep work flowing well enough (still problems a plenty that can be read about in the Technical News, which now has it’s own message board) that there are some updates on progress in the search for possible alien signals.
Firstly there is the science status page. which keeps a total of spikes, gaussians, pulses and triplets recorded as well as the number of WU’s and results held in the master science DB. It also shows the status of the data collection hardware at the Arecibo radio telescope.
A note at the top proclaims that the science status page is still ‘vastly under contruction’ and links to Future Plans. I suggest everyone reads it (it’s short after all) but here’s the gist. There’s a brief description of the more sensitive Seti Enhanced app, a description of the multibeam recorder which will ‘listen’ to more channels simultaneously and a bit about Astropulse (yes it still might happen), a project which interrogates Seti data in a different way to look for evidence of natural phenomena such as pulsars. The really crucial section in my opinion is in the Neartime Persistency Checking paragraph, namely:
For the first time since its inception, SETI@home has the potential for finding the most interesting repeating signals soon after these singals enter the database. We hope to have daily reports updated with the current "best" results when this system in put into place.
Hell, if it works I might even start crunching SETI seriously again.

Finally a word on The Planetary Society (TPS). There is lots of SETI information on this site (in the early days they provided most of the funding), including the progress of Optical SETI. This article on searching skies in the southern hemisphere using clouds of gas that act as natural ‘MASERS’ (I’m not convinced this is technically the correct term) is well worth a read too.

Rosetta@Home

Recent updates mean new screensaver graphics (See screenies below) and added support for predicting RNA structures. There are also plans for using the algorithm to design molecules for use in carbon sequestration. I believe this is called thinking outside of the box by our transatlantic chums and British upper management.

Take a look at the short video made by the R@H team on Youtube. It contains a nice description of the transcription process (which is of course entirely relevant to Folding, Predictor and other protein structure prediction projects) and description of the Rosetta screensaver.


Predictor@Home

Three batches of test units are being crunched to test whether the new dTasser app will require homogenous redundancy or not. ie WU's being sent out more than once and a quorum reached by validation. One set requires 512MB of RAM, the second requires 1GB and the third requires 1.5GB :eek: I assume such beefy requirements will be rewarded with equally beefy credit awards, but this won't be confirmed until dTasser is out of Beta.

Leiden Classical

The new app with the crlib library (5.42) has been declared stable and it looks as if the validation problem has been laid to rest. :) Maybe with the guarantee of credits at the end we'll see more of the dedicated credit chasers joining up.

Also a Java app has been released allowing anyone to construct and release their own work for crunching. The biggest bug in it so far?.....doesn't work with Vista.:rolleyes:

WEP M+2

Do you like new projects? Do you like to search for big numbers that mathematicians think are special in some way? Well here’s good news for you then. You can sign up to WEP M+2.
OK, so what does it do?

There is very little information on the project’s BOINC portal apart from that the project is in alpha and account creation is enabled. There are no forums or FAQ and it looks like there are only Mac and Linux clients for now.

A bit of clicking about turned up this page with a bit more info, including:

Mersenneplustwo numbers are those integers that are two more than a Mersenne prime. Mersenne primes are of the form 2^p-1 (http://www.mersenne.org/). This makes Mersenneplustwo numbers of the form 2^p+1. This project aims to find the factors (ie integer divisors) of Mersenneplustwo numbers.

That explains the M+2. I’m guessing WEP isn’t Wireless Encryption Protocol in this instance, but then again it might be. Very cryptic.

Team Progress:
12/03/07 to 23/03/07

SIMAP AND QMC are missing from the graphic because the team name is slightly different. If Chrislip, who founded those teams, could synch them up our overall total will get a nice little boost. If anyone spots any others that are missing shout below.

Any and all comments, suggestions and feedback are eagerly received, so remember to hit reply and add to any discussion below.
Happy crunching everyone.

Honwards and Hupwards,
Stew

Rosetta 5.48 (above) and 5.51 (below):




EDIT: Added a cap of the flash new RNA prediction routine :cool:

Thanks Stew,

Rosetta looks like a very worthwhile project & a nice vid.

I think I'll support it when my BBC climate change models have finnished.

Keep up the good work. :D
 
A quick SIMAP update that I left out above.

Project status
The project has currently no work.
The similarity matrix of the SIMAP project is currently up to date. All workunits from the march calculation period are distributed, thanks to all users for chrunchig them.
The calculation of new simap workunits containing the novel proteins from march 2007 (simap app) and their domains (hmmer app) will start around april 1st.

The number of HMMER WU's generated increases with the size of the protein matrix already SIMAPped, so in the next few months we should start to see a continuous stream of work without any project downtime. :)

Mersenne primes? Is this anything related to a program that's a lot more famous here, albeit for different reasons?

It's a completely different project to GIMPS from the look of things.

These maths projects always seem like crunching for the sake of it to me. From what I can tell only Rectilinear Crossing Number has given any potential applications for the solutions it will generate. (Printing and AI pathfinding, in case you were interested).
