• Version 2.81 of the GPU application is rolling out. It fixes the tasks that crawled for hours near 98%: when progress almost stops, or when the final part takes more than an hour, the last tickets are handed to CPU tasks and the GPU task ends normally (and is credited).
• Bigger tasks for the RTX 4090 and RTX 5090: we measured that a 65,536-ticket task only filled about 60% of an RTX 5090 (it runs about 109,000 tickets at once) and 80% of an RTX 4090. These cards now get a new, bigger GPU application (up to 131,072 tickets per task, often 85,000 to 110,000 depending on the search lane). Credit stays the same per ticket, so a bigger task pays proportionally more. First results are validated.
• New option in your project preferences: "GPU: also accept the next bigger task size than the one chosen for my card". Off by default. If you tick it, your card also gets the next size up (one step only). Useful if you want longer tasks or hours on a second GPU application (WUProp).
• Shorter tasks for the RTX 5070 and RTX 5060 Ti: they now get 32,768-ticket tasks instead of 65,536, about twice as short, for the same amount of work per hour.
• CPU cores for GPU tasks: each GPU task reserves 2 CPU cores by default. If you prefer another value, set in an app_config.xml in the Eternity project folder (BOINC Manager → Options → Read config files). We are also testing 1 core on a few card families before deciding a new default.

Thanks to pututu, Dargo75, mmonnin, Michael H.W. Weber and everyone who measured and reported!

My 5070 ran 8 tasks of the 131.000v now in 2-3 hours. I guess it could still deal with a bigger version yet. Let a alone a 5090! So I guess...

WE NEED MORE POWER, AL!! Hough hough hough! :-)

Good morning Benjamin!

Eternity II NVIDIA GPU (131,072-ticket tasks) is out of stock, refill needed 😉

@Hans Sveen: you're right, thanks for the warning! A big batch of work finished overnight and the next one only started early this afternoon. The GPU queues, including the 131,072-ticket tasks, are filling again now.

@Dargo75: 8 tasks in 2-3 hours, nice! For now, 131,072 is the biggest size.
