KaiGai's personal blog at kaigai.hatenablog.com covers programming, systems and hardware. Since 2016, 3 different Hacker News readers have linked it 3 times, most often “GpuScan and SSD-To-GPU Direct DMA”. It is still writing: the last post was on 2025-04-04, and you can follow it by feed.
Too few sampled comments (2) to say how often HN recommends it.?
Why HN links it
HN readers link this blog for its write-up of direct SSD-to-GPU DMA, which avoids sending data over PCI-Express twice. Commenters cite it as background on PG-Strom and GPU storage access.
Summarised by Claude from a sample of 2 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?
AFAIK AMD does not produce SSDs. Having said that there are some early techniques out there for DMA from NVMe drives to GPU ram directly. Like this: http://kaigai.hatenablog.com/entry/2016/09/08/003556

HN discussionThis was posted on an old HN - http://kaigai.hatenablog.com/entry/2016/09/08/003556 The major performance gain is doing SSD-to-GPU direct memory access bypassing the need for data to needlessly transfer over PCI-Express twice.
