Thank you Sir, I was just able to log-in now, don't know what happened before. :)

Onward with Panic Mode, ha ha.

Is this necessary with the low CPU CUDA80 apps?


. . That depends on whether you run with blocking sync on or off. With it on then you can get away with just the one free CPU core per 2 or 3 GPU tasks, with it off you will need 1 CPU core per GPU task plus one more CPU core free. With all the high thread count CPUs out there that should not be a problem. Even on my core 2 Duo that means no crunching at all on the CPU, but it works well. This is much the same as having sleep on or off running SoG. It is purely up to you, but there is a speed gain with it off.

Thanks to all for the help! Wish there was a wiki for this info!

I applied for an account over at Crunchers Anonymous a few weeks ago, but so far nobody has approved my request. :(

I am still unable to get any new files to work on. Is there still a problem or is it on my end??


There is still a problem, no news on what or how long.

Actually, Seti@Home is not much fun any more, with the outages, droughts, problems, speculations...and CreditScrew.
Sorry about being so pessimistic, folks.... ;-)

I reluctantly admit to similar feelings.

Though I'm not quite ready to jump ship yet, any other Space/SciFi/Alien projects that more or less provide 24-7 work with an interactive project staff? (and Linux GPU support)

The other benefit to this, it's a modern/cheap card at 30 watts that increases your WU cache by 100.

Said in the most humble method possible:

If the WU cache/deadline scenario was revamped most of us could easily ride out these issues, my fast GPU boxes run out of work fast!

Being able to sustain my 1080/1070 boxes for 2 days would capture 95%+ of the server issues I'd bet.

In any case, big thanks to the guys banging their heads against the table trying to get all of this fixed up.

AMD patch is now in:

Looks like pretty much no gaming hit, so probably the same for us.

Phoronix has an initial bench set, with I/O getting hit pretty hard, might be some rough times ahead for Intel. The bug doesn't affect AMD but the initial patch hit all 64bit systems regardless of maker, I suspect AMD will submit a patch in the next day or two to fix that, if they've not already.

In any case if one wishes to continue on anyhow (on Linux), the nopti kernel parameter will revert the patch at boot. Windows details won't be out for a couple more weeks.

I attempted to suspend a few ready to report tasks (hoping a to trickle a few in), and my entire backlog disappeared. :(

It always takes a few hours until the servers catch up with demand.


Check out the Database/file status, As of. Servers might be up, or at least showing up, but the project is still down/stuck/messed up.

Post:
So I ran across this post:

https://setiathome.berkeley.edu/forum_thread.php?id=82127&postid=1899214

That mentioned tweaking the sbs value to 1024 and got me poking around. I'm running Tbars special app and noticed that I only have a single .txt config file:

ap_cmdline_7.08_x86_64-pc-linux-gnu__opencl_nvidia_100.txt

With the following contents:

-unroll 12 -sbs 256 -ffa_block 3072 -ffa_block_fetch 1536

So I take that (new to this please bare with me) that I'm running no special options except for the Astropulse Nvidia WUs. Is this because Tbar has already built the options into the binaries, or do I have some optimizations still left on the table? Could I benefit from changing the sbs value above or additional config options?

Many thanks for the help.

Which, again, is in fact not the science database that runs informix .


Is this along with each's systems OS and primary DB documented anywhere?

Eric mentioned Informix, which I suspect is IBM's Informix DB, probably waiting on a new build from them. Or at minimum awaiting an undocumented config switch as a temp work-a-round. There was some backend working happening last night, perhaps they gave it a go and ran into further issues.

It is that and last I heard we are on an older version of it.
I would hope it is a well know issue they ran into and time, because of the large size of the db, is the only factor.


Having worked with IBM in the past, I further feel for Eric's sanity.

If it has a full length PCIe slot a Nvidia 1060 3Gb is a good value. However depending on it's age it might have an AGP slot, too far back for me to recall what would be best, if anything.
