I wonder if there is a lack of units. The time for getting work is about 4 hours and then I don't get any work.

I seem to be fully stocked on several machines so I don't think it's on the server side.

I find it is often a challenge to answer the question "why is this happening".

The event log is the first place I start. Doing a project update then seeing what it says, may contain a hint or if you're lucky a meaningful message.

Post that and perhaps we can help.

Thanks for your answer. I

Thanks for your answer. I have two machines and I only run each for about an hour a day. I usually get 'short' units of about 3-9 hours. They may be verification units. It started about a week ago, so I was just curious. I will let it go another week and see what happens.

1 hour/day translates to approximately 4% of available time. BOINC will know this and will be very wary of downloading work. If a task takes 9 hours to run and you happened to download two (per core) at once, the 2nd task would miss the deadline. So it's not really surprising that BOINC is being stubborn about requesting work. You could always be a devil and run your machines for 5 hours a day and surprise the hell out of BOINC :-). Hit the update button in BOINC Manager a few times if needed and you should be able to coax some work.

There aren't any such beasts as 'verification units'. There are CPU tasks for three separate searches and these should take (for your hardware) about 3-4 hours for GW tasks, maybe 5 hours or so for FGRP1 tasks and maybe 9-10 hours for BRP4 tasks. The BRP4 tasks are also being processed (very much faster) by modern GPUs so it would probably be best if you set your preferences to avoid them for your machines with their 1hr/day run times. GW tasks actually process quite quickly and efficiently on your i7.

Exactly 'what' started about a week ago? And exactly what do you mean by "time for getting work is about 4 hours"? If you only run your machine for 1hr/day how do you see something that takes 4 hours? Can you explain the problem a bit more please?

Cheers,
Gary.

Let me explain my set up. I

Let me explain my set up. I have two 64 bit Windows 7 machines. Both are using Thermaltake Lan boxes with mATX mobos. So there is a heat problem, although with my updated cooling (air) it is much better than stock coolers. I have E@H set to 60% of cpu time. Both have 800mb ram disks. On this machine I have hyperthreading turned off because using '8' cores just created too much heat.

For the last few months, most of my work would be in the ( about ) 3-9 hours.

I looked at the data folder and it looked like there was data that the project didn't delete that was using too muck disk space. That was probably the reason for no new units.

I just reset the project and got two 11 hr. units and two 3 hr units.

Thanks for your help

Hello *, it's my first post

Hello *, it's my first post here.

The same happens to me since 2 or 3 days: "No tasks to be performed/Nothing to be done" (German message translated by me into English).

It happens on my most powerful workstation named "nan" (ID: 5797209), while the two others (ID: 5801218 and ID: 5798184) are working on Einstein@Home as expected and get new tasks, when they have finished one. All 3 computers are running night and day.

On "nan" I just hit the update button and sometimes it helped after doing it several times. But today it seems to be in vain.

What could I do? If you have some advice please describe it simple and detailed!

Best regards,
Rudolf

Your host 5797209 has 8 tasks

Your host 5797209 has 8 tasks in cache, according to the server here. Is that not true?

Indeed, 8 tasks in progress

Indeed, 8 tasks in progress for host 5797209. Apparently I got them by hitting the update button. But my host doesn't seem to work at any of them.

The boincmgr (simple view) still says "Keine Aufgaben zu bearbeiten" (No tasks to be performed/to work at).

In the mean time host 5797209

In the mean time host 5797209 got a new number: ID: 5886165.
I united the 2 numbers to the new one.

Nothing else changed: Still no tasks.

What is to do?

Solved: The whole project E@H

Solved: The whole project E@H was stopped for some reason. So no one of 8 tasks
on my workstation could run. I spent nearly a whole day to find the reason.

Sorry for bothering or annoying you!

Hello *, now my 8 tasks

Hello *,

now my 8 tasks have finished and are sent back to the server. But my host 5886165 doesn't get new tasks: "communication is delayed" the server says
after pressing the update button.

In "sched_reply_einstein.phys.uwm.edu.xml" is a message about missing disk space though I gave 10GB which should suffice IMO, but the project misses only some MB!

My question is now: Where does E@H look for sufficient disk space? On which
partition (/, /usr, /tmp, /home, ...) and in which directory? On my host there are Terabytes of free disk space at on-board or external disk drives.

Any ideas?

Greetings, Rudolf
