The Coming Age of Extreme Heterogeneity
冒頭の質問が面白いです。
ハードウェアがまた進化期に入って、色々な方式が鹿を追う状況で、ソフトウェア書きはどれに賭ければいいのか？
特に興味深いのは RISC-V はあるのに ARM が無い所とかｗ Chapel さんも Julia さんもいませんね。

The current estimate is that the RIKEN-bound supercomputer will top out at about 400 peak petaflops at double precision. Given that the system has to fit in a 30 MW to 40 MW power envelope, that’s about all you can squeeze out of the 150,000 single-socket nodes that will make up the machine. Which is actually rather impressive. The A64FX prototype machine, aka “micro-Fugaku,” is currently the most energy- efficient supercomputer in the world, delivering 16.9 gigaflops per watt. However, extrapolating that out to an exaflop machine with those same (or very similar) processors would require something approaching 60 MW to 80 megawatts.
