Why HN links it

HN readers link this blog for its detailed posts on HPC networking, such as an FDR InfiniBand comparison covering throughput and latency. It is cited as a source for further detail on cluster interconnects.

Summarised by Claude from a sample of 1 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

    For a relatively modern cluster the standard is FDR Infiniband, which gives you 56 Gbit/s throughput. The latency for a small (< 32 kbytes) packet is less than 10 microseconds, down towards 1 microsecond for a 8 byte packet. Glenn Lockwood has a nice blogpost with much more detail: http://glennklockwood.blogspot.com/2013/05/fdr-infiniband-vs...
