Thx

Just for info: 1080ti (one of those "old cards" which has to use NO_ASM) startet with 2d14h, after nearly 11h runtime it is now at 1d18h left.

This way everyone can guess what to expect from pre-rtx nvidia cards:
1050ti 5 days+
1070 my guess 3 1/2 days
1080ti, titan 2 1/2 days
1660 my guess 3+ days

Good thing: after first completion BOINC will know how long ll_dc runs. When asking for more work (let's guess your settings are 1day work + 1day addition) it will ask for only one more, which will perfectly fit into deadline, even for slow machines.

I received a task for the RX 560 card. It seems to be working, but it needs more time to complete.

Could you please extend the deadline?

20260812 18:57:18 81866857 44300000 ca8b28a17eb9e041 7003 ETA 3d 01:05

Perhaps + 2-3 days will be more than enough.

Thank you.

Checked the FAQ on runtimes, so I'm posting here for more information:

stderr.txt:
...
No FFTs found in tune.txt that can handle 83750453. Consider tuning with -tune
...
last 2 entries in stderr.txt:
20260831 06:33:57 83750453 2160000 bea6193ead41f6ee 494.4 ETA 11:12

WU has been running for 1d 21:43:00 on a 4070 Super. This seems inordinately long. (A 2nd WU is also running on a 2nd 4070 Super; 1d 11:41:00. It's stderr.txt entry has the same "No FFTs..." and what looks to be an abbreviated last entry similar to above).

Are these WUs "bad" or did something happen running these that I should abort them after this long? (Like the stderr.txt file reached a limit of some kind?)

Ok, reb. Just an FYI, though. Since I posted this, that last entry hasn't changed and there is no newer entry in the file that over wrote a previous entry.

How long does it take until an ETA will be shown in the stderr.txt ?

After 16 minutes it is just:
2026-09-03 21:40:29 (44045): wrapper (8.3.26019): starting
2026-09-03 21:40:29 (44045): wrapper: running ./prpll (-d 0)
2026-09-03 21:40:29 (44045): wrapper: created child process 44047

Even no checkpoint after 18 minutes. FAQ tells me that checkpoint is 2 minutes.

GPU is RTX4070
OS is Ubuntu24

Now the file is filled more.
...
20260903 22:18:11 83816141 2120000 0ba2356936afc753 1071 ETA 1d 00:18
20260903 22:18:32 83816141 2140000 700738507bafd62c 1059 ETA 1d 00:02

Boinc still shows no checkpoint. Or is every new line in the stderr.txt a checkpoint? That would be 20 seconds.
But the file itself is updated only every ~10 minutes.

I have the first WU running. It's been running for 7 hours and 40 minutes, but it's been showing 100% the whole time. I'm using GTX 4070 Ti + win11

My nvidia cards are crunching the llr tasks ok, however my rx7900gre failed on four in a row. Errored out quick. Will try on a rx9070xt I have.
