Hello!

I've started a new BOINC project: Amicable Numbers

URL of the project: https://sech.me/boinc/Amicable/

Please add it to the list of projects.

Thanks in advance!

so what is the invitation code please

thank you

Invitation code: mersenneforum

thank you

Unable to create team and cannot edit Profile. Possibly a lot more work to do?

Invitation Code to setup the account. (mersenneforum)

I get an Error trying to create a Team.

Unable to handle request
Could not create team - please try later.


Account setup was fine.

Teams will be enabled when the project goes public = on February 1st.

Thank you I will be ready. I know also that we are still in Beta-testing state as well.
I am testing this now so I can do a write up for our team.

I get this error today on my Rig with only 16GB of memory.
1/26/2017 13:52:27 | Amicable Numbers | Message from server: Amicable Numbers up to 2^64 needs 33792.00 MB RAM but only 15489.51 MB is available for use.

I am now seeing this same error on a computer that has 32GB of memory and I just completed a task.

If in error ok but if not will this program require 32GB or more of memory to run?

Thanks,

It's not an error, rather than a manual hotfix for some work units. The program always uses around 800 MB when running.

Some of early work units took very long time to complete (a few days to complete, but still 800 MB of memory), so I manually set them to 33 GB to allow only very powerful PCs to handle them.

So then a computer with 64GB would be needed them.
i7-3970X 4 Cores Run time 3,309.16 CPU time 12,970.13 is in pending status ATM this rig cannot get any more tasks then.
My Servers with 96GB and 128GB are slower CPU's then this rig My i7-5960X is still running a 6 Cores task at it has 64GB of memory and is my fasted CPU ATM.
Thank,

PS
Today Most of the Powerful PCs only have 16GB of memory for an FYI.
Very few with 32GB and uncommon for home users to have 64GB of memory.

Setting to 24GB may be a better amount this way computers with 32GB of memory can run this project.

There are currently a dozen PCs on the project with 56-72 cores and >= 64 GB of memory, that's what I count for. PCs with less memory will just skip these work units and pick up normal ones.

So it is not really the amount of memory you need for this Project but the number of Cores or Threads?
Should HT be Enabled or Disabled for this Project?

Thanks,

The amount of memory required is 800 MB, and at least 2 CPU cores needed to run a work unit. I've reverted all WUs back to requiring 800 MB of memory because all PCs with 32 GB of memory or less just got stuck this night

Enabling HT gives ~20% speedup for my program, so yes, it's definitely better to enable it.

Amicable Numbers is an independent research project that uses Internet-connected computers to find new amicable pairs. You can contribute to our research by running a free program on your computer.

Current goal of the project is to find all amicable pairs with smallest member < 264.
All new findings are published regularly on the Amicable pairs list page.

Amicable numbers are two different numbers so related that the sum of the proper divisors of each is equal to the other number. (A proper divisor of a number is a positive factor of that number other than the number itself. For example, the proper divisors of 6 are 1, 2, and 3.)
