#1 New to PrimeGrid

Unread post by poppageek » Thu Mar 07, 2019 4:47 am

New to Primegrid and a bit confused by all the sub-projects. From what I read PPS seive is the best paying. I am using a R9 280x and trying out a GTX 1080. Would like to get badges but a GFN 22 ran for over 66 hours and sits in "Inconclusive" along with wingmen who it errored out or was also inconclusive. Work units that take that long make me nervous. Any advise or input more than welcomed.

Cheers!

I am 67 and getting more and more of an airhead. Wish I could say I was getting used to it. :-(

Thanks for the help!

Don't worry Poppageeks, I am 77 and am having similar problems to you, not that's much comfort.

Poppa, when you get a little older, like me, you'll wake up in a brand new world everyday and then it won't bother you anymore :lol:

The memory problems are a real nuisance. But what drives me nuts is not knowing what I just did or even why and missing things that are obvious. Like the BIG red button that says "CLICK HERE". And I am sitting there getting mad because I do not know what to do. lol

Hey Bryan! Hi Peter! :hello2:

Run your R9 280X on Genefer 22 and GTX 1080 on PPS Sieve.

Try this app_config.xml...
<app_config>
<app>
<name>genefer</name>
<max_concurrent>1</max_concurrent>
<gpu_versions>
<gpu_usage>1</gpu_usage>
<cpu_usage>1</cpu_usage>
</gpu_versions>
</app>
<app>
<name>pps_sr2sieve</name>
<max_concurrent>2</max_concurrent>
<gpu_versions>
<gpu_usage>.5</gpu_usage>
<cpu_usage>.2</cpu_usage>
</gpu_versions>

Thanks I'll give them a try.

Those GFN 22 scare me. Ran one and it went 66 hours and has sat in pending as inconclusive along with 2 others who errored out and one other inconclusive.

I stick with GFN 19 and less for the badge hunting. PPS sieve for the points. That said, someone has to wear the big boy pants for the glory. p5

Well let's hope the big boy pants aren't too big. Seems I checked too many check boxes and the 1080 has a "You feel lucky?" work unit. Boinc says 10d. Lets hope it's a wee bit shorter than that. :confused1:

That 'someday' was yesterday as far as I am concerned.

BTW - I run 1080s as well. I really like them as they score well and cope (just about) with air-only cooling

OK talk about big boy pants. One of the XS guys just got this work unit. I gotta ask; would you run this work unit? Look at some of the run times!

The 280x for some reason has a high error rate on e@h so I had it on MW@H but they have been so unreliable I decided to try PG. Do not really care about primes but the project itself is interesting and seemingly well run. The 1080 always did well on E@H. Since I passed 1 billion on E@H I am more interested in trying new things. I appreciated a well managed and reliable project. So I am thinking I may stick with PG for whatever time I have before I have to shut down GPUs due to heat. I am hoping for a cool spring and early summer.

The rest of my GPUs are 3 AMD 7870, R9 270, RX 560 and RX 570, 750TI and 660TI. Last 2 on MW@H and seti. Rest still on E@H.

We have benchmarking software if you are interested e.g. https://tsbt.co.uk/forum/viewtopic.php? ... 083#p69083

Just post a copy/paste of 20 validate WU from ONE computer into that topic and I'll do the rest. Would need to know which GPU and O/S you were using too please

Run it! RNA World WUs are difficult to get. They do run a long, along time...month or more. But you can suspend them if needed to run other projects. They are very forgiving too. Even it it errors out or you abort it, you will get credit for time worked on. It wouldn't take that many RNA WUs to get in the FB standings on that project.
