After the beta, the OpenCL application is now available to all volunteers:
• AMD Radeon and Intel Arc (A and B series), on Windows and Linux. On Linux, AMD needs the official ROCm OpenCL driver (Mesa "radeonsi" is not supported).

Task sizes
Until tomorrow, AMD and Intel cards get 16,384-ticket tasks. Older AMD cards (RX 460 to 590, Vega 56/64, Radeon VII) get smaller 8,192-ticket tasks. Tomorrow we will adjust the size for each card model to get the best out of it. To do that well we need your results first, so every task you run tonight really helps!

How to get GPU work
• Use the official drivers: AMD Adrenalin on Windows, Intel compute runtime on Linux. OpenCL 2.0 is required.
• In your Eternity@Home project preferences ( https://boinc.eternityathome.org/eternity/prefs.php?subset=project ), check that "Use AMD GPU" or "Use Intel GPU" is set to yes, and that the applications "Eternity II GPU (16,384-ticket tasks)" and "Eternity II GPU (8,192-ticket tasks)" are selected.
• In BOINC Manager, select Eternity@Home in the Projects tab and click Update. Your computer will ask for GPU work right away instead of waiting for its next scheduled contact.
• A newly attached computer may need a few minutes before it gets GPU work.

Not supported: integrated graphics (AMD Radeon Graphics, 610M/680M/780M, Intel UHD/Iris/Arc integrated) and older cards without OpenCL 2.0. They would be far too slow.

A big thank you to all the beta testers who made this possible!
