sNow! is an Open Source suite designed to manage large and mission critical High Performance Computing (HPC) infrastructures. This suite has been developed and maintained since 2008 by the HPCNow! team who have extensive experience in the use, management and administration of HPC in scientific and engineering environments. sNow! is easy to use and installs software that provides all the necessary tools to deploy and operate a computing cluster such as the operating system, monitoring tools, cluster filesystem, batch queue system as well as parallel and scientific libraries.
sNow! is specifically designed to obtain the maximum performance from a cluster, allocating the most critical services in HPC environments into a High Availability and Load Balancing layer, providing resilience and scalability for the most critical and demanding HPC environments. In addition, the software offers the possibility to replicate, over the Internet, all the critical data and configuration settings required for disaster recovery.
