Here's what you need to set in project preferences:Īccept work from other applications = yes
BOINC PROJECTS THAT USE GPU PC
Note that you can run "Amicable Numbers up to 2^64" on CPU and "Amicable Numbers up to 10^20" on GPU on the same PC at the same time! It's sad to see everyone leave the old (and unfinished) application "Amicable Numbers up to 2^64" so I decided to double credit points for it.Įveryone can switch their CPUs back to gain some more credits. And don't forget to edit your preferences and check that you're all set up to run the current search up to 10^20.Ĭredits for the old application (search up to 2^64) doubled BOINC volunteers found 552,874 new amicable pairs below 2^64Ī more detailed analysis of amicable pairs distribution will follow later this month. There are 2,390,655 amicable pairs with smaller member below 2^64 in total Older MacOS versions have poor OpenCL support and may fail to run the GPU version.Ĭongratulations to everyone who took part in this search! The MacOS GPU version has been confirmed to work on OS X El Capitan and MacOS Sierra.
BOINC PROJECTS THAT USE GPU WINDOWS
GPU requirements are the same as for Windows and Linux versions: AMD (HD 5xxx or newer) or NVIDIA (GTX 4xx or newer) GPU with OpenCL support and at least 2 GB of video memory. Sorry for the mess, but it's good that the bug is fixed relatively early, because it was hard to notice. The GPU versions for all platforms are already updated. I'll have to reissue all such work units to cover everything missed. Unfortunately, it skipped some numbers in an unpredictable way for "large primes" work units for the last 20 days 9 days. Everything should be up and running again now. The server was down today between 11:04 and 14:20 (CEST) because of a major power outage in Hetzner datacenter. GPU versions for all platforms were updated to fix "Error -58" computation error when resuming stopped task. Note that system memory requirements are higher now because all prime numbers < 10 11 need to be stored in memory for the search. I expect that this will find 2-3 million new amicable pairs in a year or so.
The search up to 10 21 has started! Over 50,000 new amicable pairs have been found in the first few days.ĭue to the huge size of search space, first stage of the search will only look for all amicable pairs where smaller number is of the form 3 N*.*p where N > 0 and p < 10 11.
