Compilation for non-AMD/Intel CPUs #141

Closed V-Z closed 2 years ago

V-Z commented 2 years ago

Hello, I'm packaging RAxML-NG for openSUSE GNU Linux and for "standard" architectures (AMD x86) it works fine, more or less, but for other architectures --- ARM, PowerPC and RISC-V I get various compilation errors. Do I get it right that RAxML-NG is not supposed to work on non-AMD x86 architectures? Or is this somehow (easily) fixable?

Hi, that's right, non-x86 architectures are generally not supported, and I'm not sure if this would be easily fixable. Maybe you could compile a non-vectorized version, but it would be rather slow. For ARM, there is an easy way to map its SIMD instructions to SSE: https://github.com/DLTcollab/sse2neon It works fine on Apple M1, however x86 emulation mode is also pretty fast there (~20% slower), so not sure if native compilation even worth the effort.

OK, thank You for clarification. Yeah, it doesn't seem to me that sse2neon would be worth of effort. So I'll focus only on packaging on x86 architectures.
