Is a way to dual boot Linux on Mac Pro M3.?

You will need an ARM version of Linux, and as I understand it, no one has an ARM Linux build that fully supports Apple Silicon features and peripherals, so your experience might be somewhere between lackluster and aggravating.

If it were me, I would install the free VMware Fusion client compatible with Sonoma and install the candidate ARM Linux distro into that as a guest. The VMware Fusion host software will fill in many of the deficiencies (networking/mouse/keyboard/display) that a standalone distro may present. There is no VirtualBox support for Apple Silicon at this time, and Parallels Desktop is a $120+/yr subscription.

If you insist on trying to install the Asahi Fedora Remix to bare metal, then install it onto an external USB drive so you don't have to touch the internal SSD (assuming it is possible to install to an external drive).

You will want to use the Asahi Fedora Remix since that is meant to be the OS to be used by users. The Asahi Linux OS, it not a full fledged OS, but only just a minimum OS used for testing the Linux drivers the Asahi Linux team are developing....there are very few apps on it....probably nothing really useful for an average user. Asahi Linux itself it not something for people to use.....best case is the Asahi Fedora Remix, but who knows how well that is since it was just released as @MrHoffman mentioned. I know that M3 support is lacking since it takes time to develop drivers for it especially when Apple doesn't provide any useful technical information. Even M1 & M2 Macs still do not have full support even after three years. I suggest you carefully read their website for what exactly works and what still does not work.

Installing Linux into a VM is usually the best option as others have already mentioned.

Asahi is the furthest along with native support.

The first Fedora Asahi Remix stable release was released in December 2023.

In addition to Asahi and the above reply, Parallels can provide various other options, as can UTM.

If you chose partitioning, you will absolutely want to have complete and current backups of everything and all partitions always, as recovery of a partitioning error or issue or corruption can mean re-partitioning and reinstalling everything.

You’ll want to have those backups anyway, of course.

I have already installed UTM but there is a great lose of functionality especially I want to use linux for CFD simulation and the available hardware available for working is limited, the question is " can I increase RAM and number of cores used by UTM?, and is parallel has more advandages than UTM?".

You’re not likely going to have a good performance experience running x86-64 Linux apps for Computational Fluid Dynamics in an emulated environment; via UTM.

You’ll need to find or build the CFD software for Linux on AArch64 Apple silicon. And that Linux availability is inherently early-stages available, too.

If the CFD app further requires a particular GPU or compute interface such as Vulkan, CUDA, or OpenGL as I would expect, that will be a further problem to get that working via Vulkan on Metal, or other such layering, too.

Pragmatically, you will need an Intel x86-64 computer whether Mac or otherwise here, preferably x86-64 with a supported GPU, if you don’t want to become much more familiar with how these pieces all fit together.

Or you’ll need a CFD app native to macOS with Apple silicon support. Preferably with Metal support for acceleration.
