This might be of interest to other users on here. I wasn't even aware of the OS's existence until earlier today.


It integrates a number of useful packages into the release:

- Code Aster: An FEA package
- Gmsh: Meshing tool
- Salome: CAD/Meshing/Post processing tool
- Code Saturne: CFD solver
- OpenFOAM: CFD solver
- Gerris: CFD solver
- Paraview: Post processing tool
- Elmer: Multiphysics finite element
- Calculix: FEA

and much, much more.

It is based on ubuntu 8.04, and needs a 64bit CPU.


I haven't installed it yet, but will do so very shortly. I'll report back on my findings later.

I'm running version 9.10 (recently upgraded from 9.0.4) but it's on my 32-bit laptop. I'll install it on my 64-bit 8-core cpu desktop this weekend and try out the software package you mention.
Thanks Kilcoo

If only these softwares would pick up on the GPGPU acceleration for paralell processing of the Multi-physics, I would co-install Ubuntu with Win 7, so I could harness the 3200 paralell processors in my desktop...

Though, AMD did just send me an invite to a new "meet the AMD people" webcast, where they are expected to debut their first Asymetrical CPU/GPU AM3 chip, the Magny-Cours. It is said to have 4 64bit CPU cores, and 8 GPU 800 stream processor cores, all on the same die!

When the software catches up, and Open CL launches (beyond CPU test phase), we are going to see software like these start competing with supercomputers...

PS: With the 5800 series ATi cards, My computer can now hold 12800 GPU Stream processors... I think that is something like 18Tflops in a desktop...


If only the software was there to use it!

Just incase I was being vague, its not a software pack, it is an OS with the software "pre-installed".


I think its running on 8.04 (Hardy).


From initial impressions, it seems to function reasonably well. Its also the first time I've been exposed to OpenFOAM, so I'll be reporting back on that in due course.

Magny cours is a 12 core CPU based on two Istanbul dies. In a 2 socket server you'd then have access to 24 core.


They are not asymmetric cores, and are all based on the Barcelona/Shanghai architecture.


Asymmetry will come with Bobcat and Bulldozer in 2011.

If the software is out there as part of a distro, they'll all be available for the Parent OS : such is the beauty of open source software. I'm going to be taking a look at these packages on my GF's 64 bit machine, as my own hardware is a bit behind the times.

Thanks for the link though : I've been looking for decent meshing software for Ubuntu, but haven't really known which way to go!

Oh, I see. So no one know if the software is in Ubuntu 9.10 (Karmic Koala, gotta love the names they give the releases)? I wonder if even though perhaps they're not pre-loaded, you could probably install them with the package manager. Anyway, I'll check this weekend and let you all know.
If not, i'll just use an old 300 Gig HD to install Hardy.

Some of it is available in the repos, others need to be installed manually.

It's a little bit of extra legwork, but well worth it for the speed increase that Karmic Koala offers over Hardy Heron (or even Jaunty Jackalope) ...

Kilcoo, I don't understand why the AMD "fusion.partner" email would state differently then... I checked their site, and your info is correct, but their email says otherwise...


Also,

I installed the CAE-Linux about 5 times now in a virtual machine, and every single time, it gets to the user/password screen, and rejects any name/pass I use. I have obviously set up these fields during installation, but it rejects my pass, and it also will not accept the Root/Root if I run the live disk...

I'm thinking of re-downloading the file, but I have spent so much time with this download for absolutely nothing but frustration at being allowed to go through the entire install process, just to be rejected at the fricken OS logon...

I had the same problem - I thought it was something I was doing. Anyway, luckily I happened to notice a stray line or two about it on the caelinux website.

To get in:

username: caelinux
password: caelinux


That'll get you in, you can then setup your own account from the admin toolbar, and delete user caelinux (however, there are cases where it still runs to that password - weird!)

Karmic isn't cooperating with me, so I'll stick to Hardy for the moment.


(Is it much faster?)

Karmic has been good to me at least. I am not sure it's faster than Jaunty, but certainly better than Hardy.
oh, and my sister started using the comp for fun. For some reason she started messing up with the network connections and screwed everything up. LOL. Now I got to reinstall the wireless drivers. Oh sister, sister.

THANKS!

I'll try that. In all of the documentation that I read, I only found the root/root name/pass combo listed. I find it odd that I cannot use the user/pass that I use when installing it tho...

It has been significantly faster (for varying reasons) on all three architectures that I've installed it on : i386, AMD64 and PPC ...

Admittedly, on the AMD64 machine this is mainly noticable due to the updated GRUB 2.0 boot system (which is an update that most people won't even get if they choose to do an install from the repos rather than a clean install from disc) but they all now seem mighty quick by comparison.

Kilcoo, beware of the speed claims. In my experience, it is generally faster, but there are a couple of things that are actually slower in Karmic. For example, SQL performance when using ext4 basically sucks in both Jaunty and Karmic. This is a Kernel bug and won't be addressed until the next release.

The included mesa build in ubuntu also includes the new code path for ATi cards (the memory manager, some gallium stuff, the 3D rewrite...). While this will pay off in terms of performance and bugs for Lucid (10.04), the current 3D performance in ATi cards not supported by fglrx (Radeon X1950 an earlier) is in general slower than in Jaunty.

Finally, updating from Jaunty produces a considerably slower boot in systems using conventional hard drives. At least that's what I've seen in three different laptops. It is possible to mitigate this and even turn it around by enabling the karmic-proposed updates and installing ureadahead, though.

EDIT: If you compile your software, Karmic comes with gcc 4.4. GCC keeps getting stricter every day, and you may need some source code wizardry if the code you are interested in isn't totally ISO compliant.
