Hello, I often saw that some Rosetta jobs did not start (0.00%).
In the status column: Waiting for memory
and the CPU is also underutilized (10% overall)

how it is possible for the manager to download jobs when there is not enough memory available to run the job.

In the past I canceled many jobs, also other jobs like SIDOC, Milkyway or LHC, because the Rosetta job worked 0% and all other jobs were blocked so that they passed the expiry date.

I don't think it's right that one job blocks all the others because nothing is calculated!

Hello, I often saw that some Rosetta jobs did not start (0.00%).
In the status column: Waiting for memory
and the CPU is also underutilized (10% overall)

how it is possible for the manager to download jobs when there is not enough memory available to run the job.

This has nothing to do with Rosetta.
How much memory are you letting boinc use? That is what determines whether or not you are going to get this message. Check Options/Computing Preferences/Disk and Memory to find out.
On my system, I let boinc have up to 90% of system memory, regardless of what else the computer might be doing. Yes, that does mean that sometimes some things have to be swapped to the swap partition, but it is necessary to make sure that boinc tasks do not get stopped because they can't have enough memory.

I don't have very many other things running, so I can set these values that high. If you do have other memory-hungry tasks running on your system, and must allot less to boinc, then I think your only options are:
a) add more system memory if you can, or
b) set boinc to run fewer simultaneous tasks.

in my preferences i have

Use RAM:

when in Use 80%
When not in Use 90% of Memmory

installed is 4GB
aktually in use .... then when i see there ist a Job from Rosetta Aktiv less then 10% cpu usage, less then 1GB Ram in use.
the Job is aktiv and after 60 minutes there will no job cange be done, the system still waiting for this Job but nothing will be done


the next JOB on what the problem is

but in the manager ist the Rosetta jab (see abobe) aktive!

[/img]

in my preferences i have

Use RAM:

when in Use 80%
When not in Use 90% of Memmory

installed is 4GB
aktually in use .... then when i see there ist a Job from Rosetta Aktiv less then 10% cpu usage, less then 1GB Ram in use.
the Job is aktiv and after 60 minutes there will no job cange be done, the system still waiting for this Job but nothing will be done

You are running boinc tasks on a system with only 4GB installed?? Amazing. If you can you might try adding more RAM to the system. I'd suggest a minimum of 16GB, but on the computer you are talking about here, you might be able to do with only 8.

You can (should?) set both of those RAM settings to 100%. Boinc runs at a very low priority, so if the system needs memory to do something else, it will swap out a boinc task to do that. Adding more system memory will reduce the chances of this ever happening.

whith oher projects like LHC, Sidock, Einstein, Climateprediction, Milkyway, yoyo, or TN-Grid i dont have such a problem only with Rosetta since beginning of this Year.
and if the Rosetta is waiting for Memory no other Project will be Crunched.

i will add some more RAM, but the chips (Sticks) are sold out, and the delivery time is currently 14 weeks :-( before next year I will not get any additional RAM :-(

ok with RAM Setting to 100% it is now crunching.

and... there are suddenly 3 Jobs of Rosetta are running, bevor were two jobs "Wating for Memory", one job "displaced".

2066 /3808 MiB are now in USE of system RAM. outsourcing: 74MiB.

:Thinking: 3 Jobs are using ~2GB RAM,
but not one Job can Start, if the are 90% of 3.8GB (3427MiB) are free??

Thanks for the help
