Linux dominates supercomputing

Filed under
Linux

Linux has firmly stamped its authority on the supercomputing sector. The latest report from Top500, which releases a bi-annual report of the fastest computers in the world, shows Linux increasing its market share in this segment from 51.8% six months ago to 74.4%.

According to the 26th edition of the Top500 report, the fastest computer on the planet is IBM's BlueGene/L System, which is used by the DOE's National Nuclear Security Administration. BlueGene, running Linux of course, achieved a jaw-dropping 280.6 teraflop (trillion calculations per second) performance, doubling its own record it set six months ago. This is the first supercomputer to break the 100 teraflop barrier.

Seven of the top 10 supercomputers in the world run Linux, the report reveals, with AIX, Super-UX and UNICOS making an appearance too. Unix managed to hold ground against the Linux onslaught - from 20.4% six months ago to 20% in this report. BSD based systems dropped off the charts, "mixed" systems took a huge knock (from 24% to 3.8%) and MacOS fell from 1.6% to 1%.

Debian GNU/Linux 8 "Jessie" Has Reached End of Security Support, Upgrade Now

Released more than three years ago, on April 25, 2015, Debian GNU/Linux 8 "Jessie" is currently considered the "oldstable" Debian branch since the release of the Debian GNU/Linux 9 "Stretch" operating system series precisely a year ago, on June 17, 2017. As such, Debian GNU/Linux 8 "Jessie" has now reached end of life and will no longer receive regular security support beginning June 17, 2018. Security support for Debian GNU/Linux 8 "Jessie" will be handed over to the Debian LTS team now that LTS (Long Term Support) support has ended for Debian GNU/Linux 7 "Wheezy" on May 31, 2018. Debian GNU/Linux 8 "Jessie" will start receiving additional support from the Debian LTS project starting today, but only for a limited number of packages and architectures like i386, amd64, armel, and armhf.
