New project sightings

[Michael]

BOINCStats lists the following new projects:

APS@home

APS@home is a research project that uses Internet-connected computers to do research into the effects of atmospheric dispersion as it relates to the accuracy of measurements used in climate prediction. More details are in the Science message board, and we may be diversifying into other areas of atmospheric science soon. Watch this space!

Cosmology@home

The goal of Cosmology@Home is to search for the model that best describes our Universe and to find the range of models that agree with the available astronomical and particle physics data. In order to achieve this goal, participants in Cosmology@Home (i.e. you!) will compute the observable predictions of millions of theoretical models with different parameter combinations. We will use the results of your computations to compare all the available data with these models. In addition, the results from Cosmology@Home can help design future cosmological observations and experiments, and prepare for the analysis of future data sets, e.g. from the Planck spacecraft.

Hmmm....very interesting....I need some invitation codes....

Another one popped up:

BRaTS@Home

What this project does is various calculations in ray tracing and gravitational lensing. What that does is simulate the bending of light from distant source by massive object. General Relativity states that light paths are bent in gravitational fields, just like trajectories of objects with mass. What I am doing here is simulating that. The images you see at http://lensing.davecoss.com/ are some I've created already. There are two planes, image and source. A point on the image plane is chosen. Then the position on the source plane that that point would correspond to is calculated. This calculation is based on the mass in the image, or lens, plane. The images I've already produced were made on either my DELL or on our Beowulf cluster here at the University. The calculation is done brute force over a large grid (basically O(N^3)). That why it takes alot of computing power. So I moved to BOINC for that. The bulk of the calculations is figuring out the deflection angle. That what is being done now. Another part is flattening a 3 dimensional object(s) into a 2 dimensional density. So it's "spacy" in so much as it simulates things that happen in space (over many Mpc's).

August 7, 2007 Testing New CAMB App
We are going to start testing a new version of CAMB that does not require a wrapper application to run. This app should eventually fix a number of issues with progress indication and checkpointing. If you would like to help out, please enable the "Run Test Applications" option on your project preferences page. It should be noted that this test app is currently only working for Linux, finishes in about a minute, and will grant 0 credit upon completion.

August 14, 2007 New URL for the Project
The new URL for Cosmology@Home is http://www.cosmologyathome.org. The old URL will still work to ensure there aren't any problems.

It looks like I've finally got the stand-alone version of CAMB running on all of the platforms. Since our Beta release is fast approaching, we need to start testing this app immediately.

This app requires different result template files and I am not sure that it will work with the older template files. Therefore, I need to let the queue run down a bit before I hand out the new app version.

Therefore, I've canceled all unsent WUs (i.e. WUs that have not been committed to a platform yet) and turned off the WU generator. At around 5 PM CST tomorrow, I will cancel all outstanding WUs, hand out the new app version, and start creating the new work.

This should give people time to complete the result they are on and send back the result. If the result isn't back by 5 PM CST tomorrow, you will not receive credit, so make sure to manually sync with the server before then if you have to.

For now, I recommend that you cancel all WUs that you cannot complete by the aforementioned deadline. I realize that this will almost certainly cause people to lose credit, but it needs to be done.

Post here if you have any questions/concerns/comments.

Hi everyone -

This is our first day of beta testing! Scott's heroic efforts to get the new code version 2.0 operational have are bearing fruit as I write this.

I just wanted to give my heartfelt thanks to everyone who has contributed so generously during our alpha testing phase:

- first of all to our loyal participants whose CPU cycles are already contributing to ground-breaking science;

- to Scott who has done a tremendous job taking this project through its alpha testing phase;

- to the NSF for providing the seed funding to get Cosmology@Home going;

- and to the members of my research group who have shared my enthusiasm for this new venture and who continue to do wonderful work.

I look forward to the next stage in Cosmology@Home!

Yours -

Ben

December 3, 2007 First paper using Cosmology@Home submitted
Chad just submitted our first paper using results from Cosmology@Home. It will appear on the online astrophysics archive at astro-ph/0712.0194 and we will also submit it to the Astrophysical Journal. The paper describes Pico, a machine learning tool for cosmology. Pico is speed in a bottle. Pico extracts the essence of the quadrillions of CPU cycles of Cosmology@Home and enables other cosmologists to speed up their calculations by a factor of 250,000. You can have a sneak preview by clicking on papers on the new Pico homepage. You might like to have a look at the acknowledgement section at the end where we mention 5 crunchers from Cosmology@Home as representatives of all our users.

Jan 30, 2008 loadd 1.07 on Linux 64-bit
loadd for Linux 64-bit optimized.

[Desti]

Apr 14, 2008 Deadline, loadd v1.17 on Windows, pop-up dialogs, loadd on other platforms
Deadline extended to 48 hours; new version of loadd on Windows deployed (two major bugs fixed); pop-up dialogs (upon abort of WUs and, hopefully, everywhere else) suppressed; loadd on all other platforms upgraded accordingly.

Apr 9, 2008 New setup of wus
Workunits' names made shorter, the former long names caused lots of troubles on Windows machines, hopefully, this is resolved now.

Apr 8, 2008 Project update
First and foremost: our scientific discussion on genetic linkage analysis is revived. Recent news are here.
http://cbl-link02.cs.technion.ac.il/sup ... php?id=169
Other things: 1. Over 1ExaFLOPs, which is 1000 PFLOPs during the last month - it is about 385GFLOP/sec ( 385 modern CPUs working all the time). 2. A lot of interesting statistics were added and validated, such as average time it takes for a WU to complete (including all the restarts), the number of computers which we'd need to buy to get the same performance, and many others: click here to see more

Apr 20, 2009 Huge THANK YOU to all the participants
The last month marathon is over. About 5 mln jobs were crunched, with much success. In particular, the last batch was extremely successful and we owe a huge THANK YOU to all who participated. We reached the overall effective throughput equivalent to a dedicated cluster of 6,000 CPUs!!!!!! This is far beyond our previous result. Some of the scientific results of the last run are surprising. We will rerun a part of the experiment to make sure the results are correct, and if they are, these are very good news. We will disclose the details if the results are confirmed. We will also open another thread in our scientific forum to discuss the results of these batches. Stay tuned!.

Hi,

there seems to be a replacement project for 3x+1: Collatz Conjecture.

They have a cuda application too, but not for Linux ATM
