Beowulf Cluster – A Poor Man’s Supercomputer
In this article, I describe the development of the Beowulf cluster,a parallel computer that consists of a network of off-the-shelfpersonal computers interconnected by Ethernet and usesLinux as its operating system. This style of building parallelcomputers has become very popular as fairly high-performancecomputers can be built in a university laboratory at a reasonablecost. Eighty percent of supercomputers listed in theTOP500 list of the fastest computers in the world are clusters.

Frontier - World's First ExaFLOPS Supercomputer
A race began around 2010 among many countries to build a supercomputer that would breach the ExaFLOPS (10$^{18}$ floatingpoint operations per second) barrier, a formidable goal. Frontier, a supercomputer designed by a team of engineers from Cray-HPE and the Oak Ridge National Laboratory, achieved this goal in May 2022. It executed the HPLinpack benchmark program at a speed of 1.102 ExaFLOPS. In this article, I trace the events leading up to the design of Frontier and its architecture. I also describe various benchmarks used to compare the speeds of high-performance computers.
