[Qlustar-Announce] Qlustar 10.1.1 shipping with OpenHPC 1.3.6
by General announcements about Qlustar 01 Dec '18

01 Dec '18

The Qlustar team is pleased to announce the immediate availability of Qlustar 10.1.1 for download at https://qlustar.com/download. This is a minor release within the 10.1 series. It integrates the recently published OpenHPC [ https://openhpc.community ] 1.3.6 release into the Qlustar CentOS platform. OpenHPC 1.3.6 ships with a gcc 8 toolchain among other goodies. A second major improvement is the further tuning of the Qlustar node netboot process that cuts the size of the initial RAMdisk delivered via tftp to a mere 35MB. This doesn't only speed up the boot process in standard clusters, but it also makes it feasible to netboot over slow and less reliable networks like e.g. a connection to a spaceship. Apart from that, this release comes with a number of bug and security fixes which were already addressed in separate security advisories as usual at https://www.qlustar.com/news/qsa-1129181-linux-kernel-vulnerabilities https://www.qlustar.com/news/qsa-1129182-security-update-bundle
