Colfax Research is the company blog at colfaxresearch.com, writing about programming and hardware. Since 2016, 7 different Hacker News readers have linked it 8 times, most often “A Performance-Based Comparison of C/C++ Compilers”. The last post was in 2019, but the archive is still widely read.
Too few sampled comments (3) to say how often HN recommends it.?
Why HN links it
HN readers cite Colfax Research's technical pages, such as a post on Knights Landing MCDRAM and NUMA layout, and mention its free online Xeon Phi courses. The comments do not judge the writing.
Summarised by Claude from a sample of 3 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?
You got me there. I think conventionally each cpu is a child of one NUMA node so in this case they had to make a NUMA node with no cpus, which isn't quite correct. https://colfaxresearch.com/knl-mcdram/#fig-3

HN discussionThe answer is obviously "no" because there's no such thing as "the set of all x86 instructions." Every vendor has many vendor-specific x86 extensions inside their microcode, some of which end up being adopted by all other vendors (essentially becoming "canonized" as x86 proper). In some cases, these extensions are widely accepted (like x86-64, which was initially developed by AMD, hence its amd64 moniker). In other…

HN discussionI agree with you completely. One other thing that I think Intel could/should do is to cooperate with one of the major cloud providers to offer reasonably priced by-the-hour remote access. There is one wonderful opportunity, though, that deserves to be better known. Intel has sponsored Colfax Research to offer free online introductory courses, which include two weeks of remote access. The next session begins August 2…
