on Myths and Legends of High Performance Computing  — it’s a somewhat light-hearted look at some of the same issues by the leader of the team that built the Fugaku system I mention below. HPCG is led by Japan’s RIKEN Fugaku system at 16 petaflops, which is 3% of it’s peak capacity. petaflops, which is 0.8% of peak capacity.

The basic question here is whether it is practical to support a large-scale C-language software stack with strong pointer-based protection… with only modest changes to existing C code-bases and with reasonable performance cost. That ‘reasonable’ performance cost is a 6.8% faster for system calls). Conceptual model.

When you own all of the code then this may involve some back of the envelope estimates, competitive benchmarking, or intuition tuned by experience. When dealing with a closed box like Microsoft’s NTFS file system it’s trickier to know if things could be running faster than they are. I recommend using the latest version of VsChromium.

For e.g., if accessing file system over WebDAV or FTP has performance issues, and it will take 4 hours to fix, then for those 4 hours, you can just kill FTP/WebDAV at kong/firewall and ask customers to use web UI or other mechanisms to work. Who performs what roles? What operating systems do you use?
