Gravitational Wave s6Bucket follow-up #2 - Progress seemingly stuck

(moderation:
I have one workunit that's been going for a whole day, and has for hours been stuck at 56.761% complete. I should add that the time remaining is blank (or rather "---").
For the moment I've suspended it, as I'm not certain it's going to finish. Should I abort it, or will it ever finish?

Have you tried stopping and restarting BOINC?
The "---" for remaining time would seem to indicate that the app has been 'spinning its wheels' for some time while the remaining time has counted down to zero. Stopping BOINC will terminate the app and after waiting a minute to be sure, restart BOINC which will cause the science app to restart from the last checkpoint saved (which should be at 56.761% or thereabouts).
If that doesn't work (no new progress in % completed after say 10-20 minutes) try rebooting the machine and then restart BOINC.
Good luck, and report back on how you go.
Cheers,
Gary.

Thank you! It took a couple of tries, and a little patience, but it now seems to be working. It's amazing that I neglected the number one diagnostic fix before calling for help.
No worries - glad you got it

My issue is slightly different . My system has a i7-4820K processor and two
R9 270X "crossfired" GPUs.
As far as the the GPUs are concerned everything is going smoothly but , a month ago ,you have altered the processor jobs from a single one to seven ! ( aiming
at its 8 cores ?? ) thence my average daily work dropped from 145000 to 50000
( and still decreasing ... ).
I don't know what you intend but "psychologically" the effect is appalling ! Could
you possibly go back to the old way or is that an inconvenience ?
Thanks in advance

Please look in BOINC at

Please look in BOINC at "Tools"->"Computing preferences".
There you'll find an option "On multiprocessor systems, use at most....
and set it to say 13. This will set BOINC to use only one core.
If you use GPU tasks than may be you'll have to rise this value to 24 and so on.

I'm sorry, but you are mistaken. The project staff haven't changed anything to do with the way things run on your machine. You need to look at changes you might have made in your local preferences or, failing that, changes you might have made to website preferences.
There must be some changes, because today, your BRP4G tasks are taking ~2.7ksecs. A day or two ago there are examples between ~5ksecs and ~19ksecs. About 4 days ago there are lots of examples where the time is between ~8ksecs and 20ksecs. Can you tell us what changes you were making to your setup to cause these big swings? It's certainly not the project doing this.
You have both BRP4G and BRP6 tasks in the mix - 146 BRP4G and only 18 BRP6. BRP4G tasks are not always available. I don't know how supply has been going lately but perhaps there were times when you couldn't get those tasks? I was surprised to see how few BRP6 you had. You falling RAC is being caused by lack of completed tasks and you will need to investigate why that is happening.
You have 138 FGRP4 tasks in the mix, many of which have been aborted. Ones that complete seem to take over 40ksecs in many cases which is far too long for an i7. Can you advise what settings you are using for GPU utilization factor and the percentage of CPU cores you are allowing BOINC to use. You have 8 cores available. You need to make sure you don't have all these crunching CPU tasks. That is under your control. Your GPUs are quite powerful and will be able to run concurrent tasks as long as you make sure you reserve enough CPU cores to support the GPU tasks.

Gary.
