Hello, I know this could be implemented into the other one.

but i saw some kind of reason for one kind of errors.

On my Computer i have an 4 core CPU and i give 3 for Boinc.

When "QuChemPedIA" is doing 2 threads at the same time one is doing fine and the other one is making only errors.

So the reason could be something arround the Virtual box that it only can handle 1 instance at the same time or something like this., actually i forced manually all other to stop and activace the one by one.


What is the error that you are seeing?
If it is this one: "Postponed: VM job unmanageable, restarting later." then you are trying to do too much at once for your machine.
Most Windows users can only use half their cores in this project. If you unhide your computers we could more easily help.

Hello! With the distributed part of SETI@home coming to an end, I've been looking for potential replacement BOINC projects and found this one. When I was a student, a long time ago, I worked in theoretical chemistry (on Gaussian95/Gaussian98 and a Valence Bond program called turtle, which, ahem, deserved its name).

Once the flow of WU from SETI@home dries out at the end of this month, I'll start crunching QuChemPedIA. :-)

There is plenty of work here, welcome aboard!

My little Windows machine happily crunches the short units without any issues we haven't discussed many times before. I was hoping the long ones might boost my RAC a little but they don't so I am happy taking whatever I get.

DavidBAM has computers with more than 1 thousand processors , so the default settings of the project have to be adapted for his profile.

2400 processors in a single pc!! How it is possible??


52 computers.

I come up with over 65,000 total processors on 52 machines.
If each core got one WU, that would be more than 10% of all the available work.

This Windows cruncher would be happy to work on some of those tasks, beta or otherwise.
7) Questions and Answers : Unix/Linux : Creating a dual boot system (Message 594)
Posted 18 Feb 2020 by swiftmallard
Post:
Does anyone have any advice on creating a dual boot system, Linux onto a Windows 10 machine? I'm looking for such info as which Linux version, partition size on a 256G SSD (125 GB free), and other options I don't even know enough to ask about yet.

My aim here is to be able to crunch more effectively for this project (read: without the encumbrances of VirtualBox), and use it as a vehicle to learn Linux in general.

I am seeing WUs that are marked as a validate error, but my wingman and I each received credit for them. I've never seen that before in any project.
Is this part of doing a re-validate on all the WUs?

Is there any advantage in creating a partition on my hard drive, installing Linux on it, and running Boinc from there?

Despite I prefer the "two app solution (big wus/small wus)", i voted for the choice 2 (only big simulation), because i think that admins (they are only 2, with a lot of other work commitments) cannot manage a too complex situation, with different apps, with different bugs, etc.

I agree completely

Abort it, the result will be invalid anyway. With the od9 WUs, I abort anything that takes longer than 8 hours.
But be aware that when the next batch of WUs begins, there will be changes in how we need to look at this issue. Hopefully, it will not exist!

Do we abort long running tasks stuck at 100% for 2 days?

Seems an absolute waste of time and electricity. Can this issue be fixed?

I abort any WU taking longer than 12 hours to complete. Haven't been sorry yet.

Needed to be clean up? I've never seen this message before. Is it distinct from unmanageable?

the record on the server for valid WU is more than 10 days. But aborting WU after 24h is a good rule of thumb in general !

With the od9 units, I abort anything running longer than 12 hours.

Post:
I have a work unit that has ran elapsed time of 23 days. I got to looking at the properties and it is just over 1 day of CPU time. However, it has locked down that CPU thread this entire time from other BOINC work. The progress kept going so I wanted to watch it for observation. Quite frankly one of the reasons I hate virtualbox projects.

That one would have been aborted 22 days ago, I've never had one complete successfully for longer than 21 hours.
