What specific Bonic (or other) task do I use just specifically for this search?

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:

Pabliedung pretty much answered your question, but I'd like to make one comment about the likelihood of us finding a prime during the double check.

As was mentioned, we're currently double checking old work that was only single checked originally. Does this make it more or less likely to find a prime? it's hard to say. On the one hand, computers have already checked these numbers, so you would think it's less likely to find a prime now. On the other hand, these numbers are smaller, and thus more likely to be prime, and there's no way of knowing how reliable the original computers were. Seventeen or Bust already had found two primes while double checking old work -- which means that the original computers were making mistakes the first time around.

Please do not PM me with support questions. Ask on the forums instead. Thank you!

The odd's are not very high for finding a prime on your first task. AKA almost 0% but many tasks can be run, each one will make us closer to finding another prime. The Double Check part I don't think makes much differences in odds.

Thank you, everyone, for the responses and information!

I do have a technical question, I'm not sure if this is the right place to ask...?

I have a 72 thread PC (36 core) Xeon running all Seventeen or Bust units. Only the first couple of units say 1-2 days remaining. However, all the remaining units are showing 20, 30 and even 52 days left?!

My work PC is an i7 4 core that is showing just 1-day remaining on all cores.

Any reason why this would be?

Also, should I turn off Hyperthreading for this project?

Thanks!

BOINC is notoriously bad at estimating stuff. Even if everything is working properly, it still has a bad habit of making bad estimates. Just ignore it, you'll most likely be fine.

Also, should I turn off Hyperthreading for this project?

If possible, turn HT off.

At any rate, I'd suggest you play with app_config to make use of multithreading, given that you have cores to spare (and a serious lack of cache and RAM bandwidth, relatively speaking). On a default BOINC instalation, create a file named app_config.xml on C:\ProgramData\BOINC\projects\www.primegrid.com and put this in it:
<app_config> <app> <name>llrSOB</name> <fraction_done_exact/> </app> <app_version> <app_name>llrSOB</app_name> <cmdline>-t 4</cmdline> <avg_ncpus>4</avg_ncpus> </app_version> </app_config>


*The -t 4 is a command for the app to use 4 cores per task, rather than the default 1. And the avg_ncpus is a tag to let boinc know that each task is taking 4 cores.

Once you've done that, go to Boinc -> Options -> Read config files for the settings to apply.


As a final note, you can try playing with these values to see what works best, but I'd suggest this as a starting point. 4 cores per task should strike a good balance between easing the insane RAM requirements while not wasting too much potential due to multithreading inefficiencies. But of course, by all means try 3 or 6 if you want. Or perhaps even 5 so that you have 7 tasks on the CPU and a full core for something else (say, a GPU), that's what I do on my quad core: I run with -t 3 to leave a free core for the GPU.
