Einstein@Home Beta Testing

• published 2008-12-18
• new BOINC API code should fix communication with graphics on Win98/ME
• should fix incorrect checkpointing introduced with previous Apps (even on Win98)
• should fix crash when App ist restarted after writing the last checkpoint
• compiled with MinGW's gcc
• 'triple switching' app package (x87/SSE/SSE2)
• override cpu detection by placing a file CPU_TYPE_0 in BOINC directory e.g. if you get 'signal 4' errors
• immediately syncs checkpoint to disk, opt out by file EAH_NO_SYNC

1. You may want to set the E@H project to get "No new work" and finish the pending work first to be on the safer side when switching platforms. You may also want to manually abort the Tasks that have not yet been started to immediately start running tasks with the new Application.
2. Exit the BOINC client.
3. Download the following file. On modern Windows systems it should open the archive automatically or after double-clicking the downloaded file, on older versions you may need to explicitly expand it e.g. using WinZip.
   • einstein_S5R4_6.10_windows_intelx86.zip
     md5sum: 93dc3c4f4980e441fe82b0acaee46b1e
4. Locate the einstein project directory. If you installed everything with default settings, it should be "C:\Program Files\BOINC\projects\einstein.phys.uwm.edu\"
   Put the files from the zip archive into there.
5. Start the BOINC client (again). "Allow more work" to the project if you had disabled that before.
   In the message tab you should see a message saying "Found app_info.xml; using anonymous platform".
   Allow work for the project if you disbaled it previously.
   New work should get assigned to the new App einstein_S5R4_6.10.
6. Keep a close eye on the results of the application.
   If the application returns erroneous results, invalid results, or produces client errors, then please rename or move the app_info.xml file in order to stop using the beta version of the application.
7. Please report any problems you may have or success using this test version on this thread.
   We encourage beta testers to subscribe to this thread as new versions of the application will be announced there.
