[M3devel] C backend -- mode or call quake?

[Daniel Alejandro Benavides D.]

Hi all:
Some parallelized RT environments gave in DEC-SRC times degradation when N ~ 3 of processors than when it was > 10 in any particular program not only compilers.
SO, I'm not so optimistic in general about that N growing too much.
This is about what SPWM3 said succinctly I don't remember the quote.
Hopefully research in other architectures like Message Passing could make the case for better compiler technology.
I don't know what else you could make with those extra N < 10 cores, I believe there should be something but in those architectures, not emulating DEC architectures like currently amd tries to do, but other new approaches, but DEC is over
Thanks in advance

I didn't know that.  Any experience on how stable it is?  Time compiling
isn't a huge issue for me either, but now that we all have n cores on a
chip, for growing n, and little way to utilize them, that would indeed
be cool.
