how is houdini 13 running on redhat/rhel/centos 7? is it pretty stable?

Yeah.

i've noticed that centos 7 gets real clunky when under load (simming, compiling, etc)

sometimes the UI freezes for 3 seconds. video that i'm streaming is choppy.centos 6 wasn't bad like this. i haven't tested it as extensively, but ubunutu had similar issues.

anyone else having this issue in centos 7 or ubuntu?

im very sad about centOS 7. To me they went the wrong direction, but this is another discussion. I would stay with 6.5 or get another distro. But dunno which one.

I'm really happy with CentOS 6 and Houdini, runs great on it. very stable!

the only reason why i'm using centos 7 and not staying with 6 is because of google chrome.

happy with fedora 20 and mint also

It's working perfectly on Ubuntu and Mint too 8)

great to hear about houdini running well, but how is your experience with the operating system while you are running houdini sims?

have you guys experienced the OS slowdowns i've described?

Forgot to mention also on centos 6 for 1.5 years and no problems.

Maybe freezes got something to do with all these GUI olverlays and pretty GUI stuff, I never had any of these problems on Ubuntu , but on Fedora I am on Mate, which I beleive makes Houdini run more smooth in my experience.

The only reason I can think of any OS to slow down during simming is because you must be simply running out of ram. I don`t think there is any other reason to this, I am actually pretty sure that thats the reason.

H13 came with a new memory allocation tool,this new memory allocation thingy would make use of all your ram after a while running your simulation. It was told that ``it was fragmenting the memory but it is not a memory leak``.
Meaning task manager may tell you that you are using all of your ram after a while you ran a flip simulation, which should not fill up your ram. But the computer would keep responding unlike when the OS uses swap due to not enough memory, which makes a pc unusable.

This issue have been fixed long time ago as I don`t experience it at my workstation anymore.

I hope I managed to answer your question

This only affected Windows. The memory allocator in Linux is jemalloc.

I tested simulation on Mint and Windows7 , In my experience , Linux use less RAM , for example I made a simple Flip Simulation , Memory Usage on linux was 6 GB , But on the Win7 was 9 GB.

Of course this is should be different on different projects and setup.
Also I think allocation memory on Windows 8 is better and use different method versus Windows 7.

Also I used a SSD drive with EX4 format for caching simulation on the Disk.
And I used another SSD drive with ntfs format too.
Saving and Reading time for large cache files from EX4 partition was 1.5 ~ 2 times faster that ntfs ! :wink:

I didn't test on Mac ,But I think because of same care structure for Mac and Linux , they are should be same for this tests .:?

Should have mentioned that, you are right, thanks for correcting

I'm using it since 2 years now and all is fine. A very good distro.
