Which vmware for multiple-cores
(This is a continuation of this thread on OF & vmware)
I am a bewildered by the choices on the vmware site.
I have an eight-core laptop running 64-bit windows 7.
I would like to install an OF friendly linux -- Debian most likely.
Can I run an OF simulation on multiple cores on vmWare player?
If not, is my other choice VmWare workstation?
You could have still used the other thread ;)
OK, I use VMplayer 3.1.4 and it provides up to 8 cores (1,2,4 and 8), so at least in theory it should work!
Now, whether it's worth it or not, that's a whole other aspect, even in real machines! I suggest that you do some tests running with 1, 2, 4 and 8 cores to solve one of your cases, so you can get a feel if using 8 cores will be worth it or not. You can see this blog post of mine: Notes about running OpenFOAM in parallel - and sort through the ideas there to figure out what you can do to improve parallelization.
Usually I use 4 cores on the VM and it does seem to be worth it, at least when I have to do parallel builds of OpenFOAM source. As for running cases in parallel, I'm never able to get linear scale up, not even in a real machine :(
Best regards and good luck!
Going back to the original question (and returning to thread topic ;)), first thank you.
I will first do an experiment. Following OF's suggestion, I will try out OF on the VirtualBox. I will let you know how it goes.
I installed VirtualBox and OF on my laptop a few weeks ago using instructions on the openfoam website. The only problem I encountered is file sharing between Ubuntu and the underlying Windows 7. I will take that up on the VirtualBox forum.
I have not yet tried running Ubuntu & OF on multiple cores.
But, what joy having OF on the laptop, and showing it off. It was a big hit at a recent trip :-)
