Presumably it works on the real server, right? I think one of the things I did on dev messed up one of the files. I wouldn't worry about it too much as long as it works on the real system.

Yes, works on the real server.

check out this post by Rafael. He posted a good example on how to set it up for SoB:

http://www.primegrid.com/forum_thread.php?id=7695&nowrap=true#111434

You'll have to create an app_config.xml file, move it to your BOINC folder and specify the number of cpu threads you want to allocate.

+1 very nice addition and very convenient to have it at one glance!

Posted 1204 days ago by pabliedung

Hi, you're looking for the “Seventeen or Bust LLR (SOB)” project. You can select it in Your account under PrimeGrid preferences.

Currently, all tasks are double checking previous work. Odds are very low you would find a prime until the double check is completed… but you never know. Max n in progress is currently around 18.6 Million… once n reaches 31.6 Million and beyond new and completely unchecked tasks will be sent out.

Check the progress here:

6) Message boards : Number crunching : Google Cloud Platform (Message 101968)
Posted 1544 days ago by pabliedung

I am wondering if anyone is running on Google Cloud Platform. They offer a 60 day free trial and I have set up a compute engine with 4 virtual CPUs to try it out. It's fairly simple to setup to run BOINC and PrimeGrid.

I've used Google Cloud (60 day trial and beyond) for BOINC and PRPNet on different gmail accounts. It works well and as you said it's easy to set up.

This link should have what you are looking for. Currently there are about 636 GFN-18 units completed per day.

Thanks for all the test results so far. If anyone has SSE2/SSE4.1 linux machines or SSE2/AVX Macs please connect and try some tests!

Iain, I ran a couple tests on my 2012 iMac. So far all workunits for CPU (i7 with AVX) and GPU (GTX 680MX) are validating just fine. Below are a few links to CPU and GPU tests:

Base 64 should never have been on the server. See this page: http://guenter.loeh.name/gc/status.html

Alright, that makes sense now. Thanks!

I see that work was loaded for base 69 skipping base 64 as the next base without a prime.

Given the upcoming GCW challenge will base 64 be included in the challenge or is the plan to move on to higher b values for now?
