Hello GPUGRID! We are deploying a new app "PYSCFbeta: Quantum chemistry calculations on GPU". It is currently in testing/beta stage. It is only on Linux at the moment. The app performs quantum chemistry calculations. At the moment we are using it specifically for Density Functional Theory calculations: http://en.wikipedia.org/wiki/Density_functional_theory These types of calculations allow us to accurately compute specific properties of small molecules. The current test work units have a runtime of the order 1hr (very much dependent on the GPU speed and size of molecule). Each work unit currently contains 1 molecule with ~10 configurations. The app will not work on GPUs with compute capability less than 6.0. It should not be sending them to these cards but I think at the moment this functionality is not working properly. The work-units require a lot of GPU memory. It works best if the work-unit is the only thing running on the GPU. If other programs are using significant GPU memory the work-unit might fail. Looking forward to hearing feedback from you. Steve

PPS Sieve will be suspended around February 7th. The exact date may vary a little. AP27, however, will be continuing. We've decided to continue searching for an AP28. More information can be found here.

The NFS@Home server was unexpectedly caught up in a campus network reorganization. That knocked us offline for a bit over a day. There may be brief outages over the next few days as we get everything settled again, but we are mostly back up with a new IP address. We apologize for the inconvenience.

Edit: The site came back up in the US on Friday afternoon PST, but because of a misconfigured firewall it wasn't available worldwide until Saturday afternoon. Again, we apologize for the issues.

With the new year we organized a new K-Tuple competition:

https://primesmagicgames.altervista.org/wp/primes-k-tuple-2/

The competition will last 3 months and is for finding new result about some k-tuple open problems (there are 7 tasks).

Unless this Boinc project were all contribute to find solutions in latin squares field donating CPU power, the competition is for people that like to code programs and experiment with mathematics to find new solution by them-self.

For this project instead, the DB with all the solutions will be available as soon as November and December months will be finished to being processed for dividing the solution by their ranks.

Thanks
