| PelicanHPC是基于Debian的自启动运行光盘镜像，其宗旨是简化高性能计算集群的安装。其前端节点（或者是真实的计算机，或者是虚拟机）直接
从该镜像引导。计算节点则依靠预执行环境（PXE）来启动，它们以前端节点为服务器。集群的所有节点都从相同的光盘镜像获取它们的文件系统，因此，所有的
节点都运行相同的软件。该光盘镜像通过运行一份单独的脚本创建而得，这也使得可以基于额外的Debian软件包来定制该自启动运行光盘镜像。 Michael Creel has announced the release of PelicanHPC 1.5.1 (formerly PrallelKnoppix), a Debian-based live CD designed to make it simple to set up a high-performance computing cluster. This updates fixes the recent "predictable randomness" vulnerability in Debian's build of OpenSSL and all users are strongly encouraged to upgrade. From the announcement: "PelicanHPC1.5.1 released. Changes: fixes a major security problem related to SSH keys, all users who connect their cluster to a network are strongly encouraged to update; added fail2ban to discourage brute force SSH attacks; MPITB and other example code for Octave is now pre-compiled; package updates, including Octave 3.0.1 and OpenMPI 1.2.6."
