Thanks for the file. Did the user experience slow-down while generating the profile (other than the slow-down by valgrind)?

Hi Ruopeng
All the boxes are fully upgraded. Some of them have an Nvidia GPU and some of them only have onboard video, but the problem is the same on all of them, so probably not that.
I sent you a callgrind file from one of my users, I hope that can provide some insigts.
Thanks,

We tested on our CentOS 8 machines as well as CentOS 8 VM but did not notice any slow-down. I personally run freeview remotely on a CentOS 8 machine occasionally and have never experience such an issue. I’m at a loss, too. :( I’m just shooting in the dark now - as I mentioned before, have you tried updating your graphics card driver? I remember quite a while ago we once had a slow-down issue on one of our machines. It turned out to be a conflict between the graphics card driver and the vtk engine we used (not sure whose fault it was). After updating the driver the problem went away.

Hi again
Also the same when run via X11 from a beastly compute node.
As it runs just fine on Ubuntu 16.04 with the very same NFS storage backend we are at a loss, but the finger points at something with CentOS Stream I guess.
Anyone using it on CentOS 8 Stream with success?
Mvh.

Hi again
The user reports freeview being unusable right off the bat this morning.
He left it running in that state, is there anything I can do to capture something that might provide insights?
Mvh.

Hi
We've moved to an environment modules setup for the new HPC installation and I've made modules for 5.3.0, 6.0.0 and 7.1.1, which all exhibit the same symptom.
I installed a dev build this morning and one heavy user reports the following from working with it:
" I used freeview heavily during the day and it worked fine.
Now logged on again (with the same viewer open) and it was impossible to work with.
Even killing it takes forever, and after the window disappears the terminal is still working on something.
Had to also kill the terminal. "
We run Thinlinc as thin client point of entry, freeview is run directly on the login nodes which are fairly beefy things with 256GB RAM.
Mvh.

Hello Torkil,
Not sure what version of Freesurfer you are using, but if it’s an older release, it could be interesting to compare the performance with one of the latest development builds (not a release) from *MailScanner has detected a possible fraud attempt from "secure-web.cisco.comhttp://secure-web.cisco.com/ [1]" claiming to be*

There’s an archive and RPM for CentOS7 and an archive for a CentOS8 build.

Hi Ruopeng
The users all agree it is GUI responsiveness. Everything else can run just stellar on the very same desktop, matlab etc, at the same time as freeview stalls.
Mvh.

Can you tell what part of the program slows down the most? Data loading? GUI responsiveness? Image/3D rendering? Or just in general? If it is the rendering, maybe try updating the graphics card driver to the latest?
Best, Ruopeng

Hi
We have an older Ubuntu 16.04 HPC installation on which Freeview runs just fine. We also have a brand new CentOS 8 Stream HPC installation with much better hardware on which Freeview slows to a crawl after a bit of use.
There's no error as such, it just slows to the point of being unusable.
Any suggestions on how to fix it, or pinpoint the cause?
Thanks,
Torkil
