Thank you for your answer. It doesn't seem like a common case...

I tried formatting, just in case, but still the same symptom.

Even later, if you have a solution, please share. :)

CMS Simulation error

hello. I have a question.

During the LHC project, nothing else is wrong, but only the CMS Simulation gives an operation error.

What are the causes and solutions?

I do not know.

I went to the file path you mentioned and deleted all folders and subfolders.

But I still get the error.

No... I opened up my virtual box and checked the status of the virtual machines.

However, there is no box marked with a yellow triangle (warning).

Any other solutions?

hello. After installing the latest version of Windows 11 built at the end of September 22, an error occurs.

Other operations are fine, but only the atlas gives a calculation error.

Is this related to windows 11 update?

Oh, the problem has been solved.
I didn't take any separate action.
It is currently operating normally.
Thank you, everyone. :)

I don't use the xml file.

We only use the environment setting of the LHC project.

2. No, there are no other projects. (Using the box)

Um... There's no virtual machine.
The vmbox opens, but there is nothing.

Thank you. I recently formatted my computer.

That's why I'm confused. :)

First, thank you for your answer.

I have two computers.

One computer uses 5950x/1050ti.

One computer uses 5950x/3080 gpu.

The computer that I had a problem with is the 5950x/3080 gpu computer.

You can't receive your work from that computer...

==

I think maybe,

In adding/removing programs in Windows 11.

Virtual desktop and sandbox functions.
When you activate it,

It seems that the virtual box is not working and that the operation is not received.

I deleted the function and restored it to its original state.

But I still don't receive the work.

I run four Atlas with 32 gigabytes of memory.

However, there is no problem if one core is assigned to the task.

When allocating two cores, the task cannot be received.

What's the problem?

I have read your link carefully.

1. There is no difference between running ATLAS directly on Linux OS or simulating ATLAS on Windows.

2. Formula for memory required for Atlas project (except Hyper-Threading)

5950x = 3000 + 14400MB (16core) = 17400MB

+@ 3GB of extra memory per vbox


3. Using as few cores as possible reduces overhead and increases efficiency (but ends faster with more cores)

Did I understand correctly?


p.s: AMD virtualization problem has already been solved :)

Hi, I'm running 10 ATLAS simulations using 5950X on one computer.

The current state uses three threads. Allocate unlimited memory and disks.

If you increase the number of cores allocated per thread to more than 3 cores, is there a difference in processing time?

and

ATLAS is using too much memory.

Does it benefit from memory usage or work efficiency if you install Linux with vmware on your computer and run ATLAS in it?
