[dna] new DNA@Home runs up and going Nové okno
Then you're missing the context.

Hehe, no, I simply interpreted it a bit on my own view to fit my need. ;-)
but are choosing not to because Travis doesn't jump at your command. There must be a lot of live, active projects that you refuse to run.

LOL, a funny nice jump to conclusions and a perfect reversion of what I really said.

MilkyWay@home Down Nové okno
Hey everyone,

Looks like the database has been down for a little over 30 hours and the boinc daemons are still struggling. Not entirely sure what happened, but I'm working through trying to fix it. I apologize for the slow progress being made, all of the major MilkyWay@home scientists, including myself are visiting collaborators in Canada and have been quite busy. I will try to get things fixed over night.



Everything seems to be working now. I'll check back in the morning to make sure everything is still working.

Project News Sep 23, 2016 Nové okno
Some good news! We recently published an article in Nature titled "Accurate de novo design of hyperstable constrained peptides". We would like to thank all Rosetta@Home participants for their help with this work. In the paper, we present computational methods for designing small stapled peptides with exceptional stabilities. These methods and designed peptides provide a platform for rational design of new peptide-based therapeutics. Constrained (stapled) peptides combine the stability of conventional small-molecule drugs with the selectivity and potency of antibody therapeutics. The ability to precisely design these peptides in custom shapes and sizes opens up possibilities for "on-demand" design of peptide-based therapeutics. Other developments described in the paper: We can now accurately design 18-47 amino acid peptides that incorporate multiple cross-links. We can now design peptides that incorporate unnatural amino acids. Specifically, we designed peptides with a mix of natural L-amino amino acids and D-amino acids (mirror images of L-amino acids). D-amino acids tend to provide better protease resistance and lower immunogenicity; both of which are desired properties in a therapeutic peptide. Unnatural amino acids also let us sample much more diverse shapes and functions. We can now design peptides that are cyclized via a peptide bond between their N- and C-terminus. Cyclic peptides provide increased resistance against exopeptidases as they have no free ends, and thus are ideal candidates for engineering peptide therapeutics. We are now working to use these computational methods for designing peptides that target therapeutically relevant targets, such as, enzymes that impart antibiotic resistance in pathogenic bacteria. Structure prediction runs on Rosetta@Home for these designed peptide models played a key role in selection of good designs that were experimentally synthesized and characterized. Thank you all for your help in making this work possible! -- Gaurav B. For more information: IPD News. Nature paper "Accurate de novo design of hyperstable constrained peptides".

Some security and cosmetic upgades Nové okno
We have added the option to access the C@H website more securely via "https", if you'd like to do so, you can update your bookmarks to use https://www.cosmologyathome.org. For now this remains purely optional (for example, if you don't know what https is, you can ignore this). At some point in the future, we will likely move to requiring this, but we'll give warning and post more details then.

Also, I've fixed a number of minor cosmic things about the site, most notably 1) the BBCode buttons when posting to the forums now work 2) a number of pages which were rendered too wide should now correctly fit the screen. If, as you're using the site, you find any other glitches, please don't hesitate to take a screenshot and post on the forums so we can fix things! Thanks all! (Edit: ha, oops meant to say *cosmetic* things above, although I'll leave in the somewhat appropriate typo)

SSL connection option Nové okno
For those with BOINC clients above version 7.2, there is now an option to connect with SSL on the URL:


This server runs a web-front end and scheduler for this project. To use it, please detach fron the project, and re-attach using the new HTTPS URL.

The other project daemons still run on the same server as before. The old server and URL will remain in place until further notice.

So far our tests of this distributed server setup works fine, and we would appreciate feedback in case of problems.

World Record Twin Primes Found! Nové okno
On 14 September 2016 04:24:46 UTC, PrimeGrid’s Sophie Germain Prime Search found World Record twin primes: 2996863034895*2^1290000±1 The twin primes are 388,342 digits long, eclipsing the previous record of 200,700 digits. They will enter Chris Caldwell's The Largest Known Primes Database ranked 1st for twins, and each entered individually ranked 4180th overall. The discovery was made by Tom Greer (tng*) of the United States using an Intel(R) Xeon(R) CPU E5-2623 v3 @ 3GHz with 32 GB RAM running Windows 10 Professional. This computer, using LLR, took approximately 23 minutes to complete the primality tests of both primes. Tom is a member of the Sicituradastra. team. The prime was verified on 15 September 2016 01:32:51 UTC, by Don Palmer (Don Palmer) of Canada using an Intel(R) Core(TM)2 Duo CPU E7600 @ 3.06GHz with 4 GB RAM running OS X 10.11.6. This computer, using LLR, took approximately 1 hour 37 minutes to complete the primality tests of both primes. Don is a member of the Team Canada team. For more details, please see the official announcement.

MilkyWay@home Version 1.38 Released Nové okno
Hello Everyone,

I just released the newest version of the MilkyWay@home application (1.38). The only major change to this version is an inclusion of the newest BOINC libraries in an attempt to improve compatibility with the new graphics cards.

Mac users will still receive the 1.36 application version for the time being while we work on securing a new Mac computer to build and test on for the future.

If you notice any issues with this application please post them here.

Happy Crunching,

Changes to the multicore app configuration Nové okno
After analysis of results from the multicore app (see this thread) we have made the following changes

- Minimum VirtualBox version required is 5.0.0
- Maximum cores reduced from 12 to 8 (this can be overridden in app_config.xml but we have seen severe performance issues above 8 cores)
- Enforced that hardware acceleration is enabled on the host. This should stop the -148 ERR_EXEC errors because WU will not be sent to these hosts.

Please continue to provide your feedback on changes we make.

Project News Sep 12, 2016 Nové okno
In the last few weeks our project has experienced significant issues resulting in slower than usual work unit distribution, result processing, and credit granting. The cause of this was due to the increasingly large number of new hosts causing our database server to become very sluggish and eventually run out of disk space. Our short term solution was to reconfigure and optimize the project configuration and existing database server, purge old data quicker than usual, and temporarily stop resource intense database queries. This recovery mode will continue until the project stabilizes which may take a few days to a week. An interim solution will be to temporarily upgrade our database server and thanks to our sys admins, we already have a machine ready to go that has plenty of disk space and double the memory. The upgrade will require a day of downtime which is planned to happen early this week. The long term solution will be a complete system hardware upgrade to all our servers. The BOINC server software will also be upgraded. We are in the process of ordering these machines and hope to have them running within the next few months. The project is somewhat stable now and clients should be getting work as usual. However, result processing and credit granting may still be slow and our status information/page may not be up to date as we are in recovery mode and our servers continue to catch up on things. Work history will also be shortened to temporarily save space. We expect things to be back to normal in a few days to a week. Sorry for any inconvenience and thank you for your continued contributions!


Thanks to David Vignoni for graphics and inspiration.
