I've got 2 E@H CPU tasks that have been "waiting to run" since 7/28. Several other E@H tasks (GPU & CPU) have run since then although none are currently running. Several CPU & GPU E@H tasks are "ready to start".

The "waiting" tasks are both Gamma Ray Pulsar Search #2 1.10.

I'm running BOINC version 7.0.64 (x64) under Win 7 Pro SP1. Been running for about a year with no issues. Rosetta and Climate Prediction are running normally.

Any hints or relevant questions?

A Reset seems to have started the GPU tasks and resent the two tasks mentioned above and described as 'lost' in the log. No CPU tasks running yet.

E@H Tasks "Waiting to Run"

Back to my problem of yesterday.

Having reset the task, I saw log messages reporting the resending of lost jobs followed by what appears to be downloads of all the apps plus several GPU and CPU WUs. The GPU WUs (BRP5) have been processing and reporting fine, but the CPU WUs have not been allocated any processing time for over 24 hours. The first in queue 'Ready to Start' tasks are again Gamma Ray Pulsar Search #2 1.10 and there is a casA S6 task later in the queue.

Again, any thoughts or suggestions?

My hardware is i7-3770 with 32GB of memory. Lots of disk space

Hi, I had a quick look on

Hi,

I had a quick look on your tasks list for that PC. It seems like it only crunches GPU workunits. Although you downloaded CPU workunits there are no finished, pending or errored out. For some reason your PC downloads tasks, but does not start crunching them. I think there is something wrong with your settings. Maybe you can tell us something about the settings for that PC. How many cores is it allowed to use? How many GPU tasks is it running? ...

I think this has to do with

I think this has to do with resource share between projects.
You said that you run 3 projects (Einstein, Rosetta and Climate Prediction), what are the resource share for each project?

Neither Rosetta nor Climate Prediction has any GPU app so I think that Boinc is trying to honor resource share by mainly running Rosetta and Climate Prediction on your CPU and Einstein on the GPU.

My advice is to be patient and let things run, the tasks here have a 14 day deadline and if they don't start for a few days that shouldn't be a problem. Boinc do monitor things and will do whatever it takes to not miss a deadline.

I also run a i7-3770 and the Gamma Rays take about a day to complete and the S6 CasA about 8.5 hours, so if your tasks waits in cache for a few days they should still have plenty of time to finish before their deadline.

Local prefs for this machine

Local prefs for this machine are set for use of 3 cores (6 CPU tasks) out of 4. One GPU task operates, but that is not set anyware that I am aware, I simply have one video card. It can use 60-80% of 32GB of memory, depending on activity and up to 40GB of disk space. Most of the time, little foreground activity is occurring and mostly the standard Windows tasks plus an HP printer task are running in background. There are no obvious disk or memory constraints.

Hopefully, this is helps.

You may have something with

You may have something with the resource share if the GPU tasks are now considered to be part of the overall calculation. I believe that previously, scheduling ignored them for CPU tasks.

The tasks are scheduled as CPDN 200, Einstein 100, Rosetta 100.

No sign yet of any Einstein CPU task running. :(
