GPU version 1.12 bug
This version had a bug, so I had to cancel all work which was in progress for this version and then reissue all work units which were processed with this version only, i.e. all work units that have two results with GPU version 1.12 in "completed and validated" state. 16433 work units have been reissued, it's approximately 1 day of calculations.
The project is back to using version 1.11 for now. I'll release a proper fixed version later today.

Update on project progress and badges
227,482 amicable pairs have been found so far, ~340,000 are yet to be found according to my estimations. Due to the way this search is organized and how amicable numbers are distributed, I expect almost all of those ~340k pairs to be found before the search reaches 50% in a couple of weeks, and only a few thousand of new pairs will be found after 50%. So if your target is to get some of the discoverer badges, now is the time to crunch with everything you've got.
Since there will be only a few new pairs after 50%, this is when I'll introduce credit badges.

Project status update
After the recent fix for the very short work units issue I had to regenerate remaining work units using the new code. Of course there are fewer work units left now because they are not "very short" anymore, and the server status page says that ETA for current goal is June 18th, 2017. This is correct and it means that the next goal will be to find all amicable numbers < 10^20 and it will start in the summer. 10^20 is ~5.42 times larger than 2^64 and the new application will be slower because it will have to deal with numbers that don't fit in 64 bits. So the next goal will take 8-10 times more time.

TEAM CHALLENGE starts soon!
The first team challenge starts on March 1st, so I've temporarily increased task-in-progress limits: it's 4 tasks per CPU core + 100 tasks per GPU now. You can use the time left before the challenge to bunker more tasks.

GPU application version
GPU application version is
available for beta-testing now released as of February 28th. Both AMD (HD 5xxx or newer) and NVIDIA GPUs are supported. 1 GB of video RAM is required. To test it, enable "Run test applications" in project preferences here: https://sech.me/boinc/Amicable/prefs.php?subset=project

-------=======> Challenge standings <=======-------
SUSA has issued a Team Challenge starting 0000 UTC March 1.
Unfortunately, there was a bug in the challenge sign up SW that wouldn't allow the name Amicable Numbers to be shown in the project field. The bug was reported and has been corrected by Willy @ Bstats but he said it would take a while for project name to show up.
You can sign up your team HERE

For all Gridcoin users: whitelist poll
A poll has been created to whitelist Amicable Numbers:
Whitelist Poll : Should Amicable Numbers Be Whitelisted?

Project is to be launched on January 30th!
Since everything is running smooth, I've decided to open the project for public tomorrow, on January 30th.
All participants will be able to choose/create teams then.

Attention! There are very huge work units on the project now
Application is not hung if it's running the same task for many hours.
You don't need to abort it as long as you're able to finish the task within
2 days 9 days.
My work generator is certainly not perfect, and I'll improve it before generating new work units. It was supposed to generate work units that would take no more than 2 hours on a typical 4-core Core i7 PC.
All completed huge work units will be eventually awarded with appropriate credits when they're validated.
UPDATE: I've extended deadlines for all pending tasks from 2 days to 9 days. If you have a long running task, you should check progress after 24 hours, and if it's more than 13-14%, you should be safe to finish in time.
UPDATE 2 (2017-01-25, 13:18 UTC): Work generator is now improved. New work units will be much more uniform. All work units starting with WU#4001 should have run time of no more than a few hours on 4-core processors.

First amicable pairs found on the project
There are already 15 new amicable pairs found so far after just 12 hours of crunching!
Here is the list of new pairs: https://sech.me/ap/log/2017/2017-01-23/VOLUNTEERS%40BOINC.txt
Volunteers that found each pair are shown in the order they found this pair.
Congratulations to the people involved!

The project is currently in beta-testing phase: account creation is limited, expect bugs/instability. Once all obvious hiccups are fixed, the project will be open for public.
ETA for public launch: February 1st, 2017
