MOSIX Version 2 (MOSIX2) for Linux-2.6 is a management system for clusters and organizational grids. This research paper from Hebrew University of Jerusalem describes the use of MOSIX2 Management System for Linux Clusters and Organizational Grids. MOSIX2 is a management system targeted for high performance computing on x86 based (32-bit and 64-bit) Linux clusters and multi-cluster organizational grids. It is implemented as a software layer that provides applications with an unmodified Linux runtime environment. It concludes with logical clusters allow the sys-admin(s) to divide nodes into private partitions.
Linux is the most popular open source project. The Linux random number generator is part of the kernel of all Linux distributions and is based on generating randomness from entropy of operating system events. This paper published by Hebrew University of Jerusalem gives a description of the underlying algorithms and exposes several security vulnerabilities. In particular, the university shows an attack on the forward security of the generator which enables an adversary who exposes the state of the generator to compute previous states and outputs.
