Comment Re: I'd like to use Linux, but I can't due to syst (Score 0) 27

I've been running Debian 8.2 without any problems on a wide range of computers, from desktops to my latest Skylake-based laptop. I haven't had any software issues at all. I'm curious what kind of problems you're having? And it's not like Mac OS X doesn't use something similar to systemd (they do, called launchd).

Comment Re:The Intel compiler still anti-competitive (Score 1) 225

I've tested version 13 of ICC using Povray on several of my AMD and Intel systems. I can tell you that the dispatch code works as you would expect: AVX (but not AVX2) code path does work on the FX8350, does not work on Phenom II x6 1090T so switched to SSE2 path. Of course, compiling without dispatch will cause seg faults on processors that don't support AVX or AVX2. But that doesn't necessarily mean ICC is the fastest compiler for AMD. For Povray at least that would be GCC.

Comment Re: Who is buying the FX-8370? (Score 1) 119

Depends on program actually and what version of ICC. What you're describing was old ICC behavior before they were sued. My own tests compiling Povray with ICC 13 I've found that the ICC dispatch code does work properly on my FX 8350. In other words, compile with AVX dispatch support and the program will choose the AVX code path, which gives the same performance as compiling with only AVX support (the dispatched program also runs on my PhenomII 1090T, but the AVX exclusive program doesn't). But that doesn't necessarily mean the ICC code is always faster. Sometimes GCC code is faster because GCC can explicitly order instructions for Bulldozer, but it doesn't do autodispatch. That has to be coded separatley by the programmer.
