High Performance Linux Kernel Project — LinuxDNA
Thaidog submits word of a high-performance Linux kernel project called "LinuxDNA," writing "I am heading up a project to get a current kernel version to compile with the Intel ICC compiler and we have finally had success in creating a kernel! All the instructions to compile the kernel are there (geared towards Gentoo, but obviously it can work on any Linux) and it is relatively easy for anyone with the skills to compile a kernel to get it working. We see this as a great project for high performance clusters, gaming and scientific computing. The hopes are to maintain a kernel source along side the current kernel ... the mirror has 2.6.22 on it currently, because there are a few changes after .22 that make compiling a little harder for the average Joe (but not impossible). Here is our first story in Linux Journal."
IMHO This is a great development, for one important reason.
Portability of the kernel.
GCC is a great compiler, but relying on it excessively is a bad thing for the quality of kernel code, the wider range of compilers used, the more portable and robust the code should become.
I know there will be the usual torrent of its-just-not-open-enough rants, but my reasoning has nothing to do with that, it is simply healthy for the kernel to be compilable across more compilers.
It also could have interesting implications with respect to the current GCC licensing 'changes' enforcing GPL on the new plugin structures, etc.
GCC is a wonderful compiler however it has in the past had problems with political motivations rather than technical, and moves like this could help protect against those in the future (some of us still remember the gcc->pgcc->egcs->gcc debarcle).
Of course no discussion of compilers should happen without also mentioning LLVM, another valuable project.
