New project - Amicable Numbers

Post by UBT - Timbo »

Hi all

Another new BOINC project is now available:

Add Project URL:
Apparently, the WU's require 800 Mb each, so be careful trying to run multiple tasks !!

The Team page is here:

We're off the ground now :)

Each WU takes about 6ix hours for 3,500 credits on a 3.4GHz i7, pays quite well!

It took just over 700Mb of RAM and tries to grab all the cores if you'll let it.

Creat an app_config.xml in the project directory and add:

Code: Select all

<app_config>
 <app>
  <name>amicable_2_64</name>
  <max_concurrent>1</max_concurrent>
 </app>
 <app_version>
  <app_name>amicable_2_64</app_name>
  <plan_class>mt</plan_class>
  <cmdline>--nthreads 1</cmdline>
  <avg_ncpus>1.000000</avg_ncpus>
 </app_version>
</app_config>
to limit it to one WU at a time running on one core.

Change the <max_concurrent>1</max_concurrent> to run more than one at a time, change both the <cmdline>--nthreads 1</cmdline> AND the <avg_ncpus>1.000000</avg_ncpus> to run it on more cores at a time.

Allowing two WUs and two cores DOESN'T mean you'll get two WUs running on a core each, you'll get two WUs claiming two cores each! It also didn't appear to work too well as a multicore programme although that might only be me. I had one WU running using 8 cores and another seven WUs from other projects also running. Not bad for only eight cores :D

Hi Mark

Thanks for the tips and well done on getting some points on the board. :-)

I'm still waiting for my first task... :-(

The memory requirement isn't that bad as long as you have enough RAM in the first place...OTOH, the VGTU project requires very little RAM, so 1x Amicable, plus a few VGTU seems like a good idea ;-)

EDIT (abt 10:35pm):

So I checked the Amicable project website and it says:
Work
Tasks ready to send 3766
Tasks in progress 1651
but when I try an update (with all CPU work suspended) to get some tasks it says:
212775 Amicable Numbers 2/1/2017 10:40:11 PM No tasks sent
212774 Amicable Numbers 2/1/2017 10:40:11 PM Scheduler request completed: got 0 new tasks
212773 Amicable Numbers 2/1/2017 10:40:08 PM Requesting new tasks for CPU
212772 Amicable Numbers 2/1/2017 10:40:08 PM Sending scheduler request: To fetch work.
Oh well...none for me then !!

EDIT: (abt 10:50pm)

Perhaps, now I know why - the applications are for:
Microsoft Windows running on an AMD x86_64 or Intel EM64T CPU
Linux running on an AMD x86_64 or Intel EM64T CPU
So, even though I have a 64bit CPU, I've only tried this on a WIndows XP x32 OS....so, maybe that's why I have no tasks?

Hi all

I've now had some GPU tasks from Amicable on my Win 7 x64 box.

Tasks didn't take too long and credit is good too.

However, from what I've read on the Amicable message boards, there is a limit to the number of tasks that will be available (in this batch?) so they will run out by mid-June.

So, if you want to make an impression on this project, then I suggest you join up.

Badges will be available for total credit scores in excess of 1 million.

regards
Tim

Hi

I was just about to mention this but you beat me to it. Credits appear to be about ⅓ the value of Moo! or 3 times the time taken for similar credit.

Hi all,

New GPU tasks are now available from Amicable.

Be sure to have the latest drivers plus the GPU must have at least 2Gb of RAM.
