Einstein@Home GPU Application for ATI/AMD Graphics Cards
After more than a year of work by Oliver Bock, Bernd Machenschalk, Heinz-Bernd Eggenstein and other developers, we are pleased to announce the release of the first Einstein@Home application for ATI/AMD Graphics Cards.

This OpenCL application, which searches Arecibo data for new radio pulsars, is about a factor of ten faster than the same search running on a typical CPU. The application is currently available for Windows and Linux computers with Radeon HD 5000 or better graphics cards. We hope to have a version for Macintosh (Apple OS X 10.8, Mountain Lion) sometime this summer, but there are still some problems that need to be fixed or worked around.

Volunteers who wish to run this application will need to install version 7.0.27 or later of the BOINC client. Please see this thread for more information, or if you want to ask questions.

Many thanks to the AMD/ATI team for their support in the OpenCL software development effort.

Einstein@Home volunteers discover three new radio pulsars in Arecibo data
Einstein@Home volunteers have discovered three new radio pulsars (J1901+0510, J1858+0319, and J1857+0259) in Arecibo PALFA data! Congratulations to:

• John A. Lorimer Jr. (USA)
  
• Ugur Munir Kir, Guzel Sanatlar Saatchi & Saatchi (Turkey)
  
• Philipp Kählitz (Germany)
  
• Termit (Russia)
  
• Philemon1752 (Switzerland)
  
• edgen (Russia)
  

Further details about these and our other newly-discovered pulsars can be found on this web page, and will be published in due course.

Application changes
Our Gravitational Wave search "S6Bucket" is nearing its end. As usual while processing the last tasks of a run, locality scheduling isn't very effective, and the download volume increases. People with a slow (or expensive) internet connection may want to back off from Einstein@Home for a few days.

The next Gravitational Wave search "S6LV1" is already set up, we expect to ship the first tasks of that search in the next few days.

In the past days we also started shipping a new version of the Radio Pulsar search application (BRP4). This is in preparation for using a new data file format which should reduce the data (download) volume of a BRP4 task to about a half.

Participants using 'anonymous platform' (app_info.xml) need to update their application setup.

Please refer to our Technical News message board for details and updates about these applications. 5 Mar 2012 12:07:53 UTC · Comment

Three new pulsars found in Parkes Multi-Beam Pulsar Survey (PMPS) data!
Einstein@Home volunteers have discovered three more new radio pulsars in data from the Parkes Multi-Beam Pulsar Survey (PMPS). Congratulations to:

• Rolf Schuster, Neu-Isenburg, Germany
  
• Rudzik Boguslaw Sobczak, Krakow, Poland
  
• Sirko Rosenberg, Bautzen, Germany
  
• Steve Mellor, Perth WA, Australia
  
• Ton van Born, Amsterdam, the Netherlands
  
• Darren Chase, Adelaide, South Australia
  

Further details about these new discoveries can be found on this web page and will be published in due course. These discoveries bring the Einstein@Home discovery total to 9 new radio pulsars in the first two months of 2012!
