OpenStack installation at CSCS offering classical Infrastructure-as-a-Service interfaces.
Every user is assigned their own home directory with sufficient storage space to store codes and documents (/home)
A shared parallel file system to store project data (/store or /project)
Access to compute nodes is provided with the use of an integrated workload manager (Slurm). This provides traditional batch processing services through a pre-defined queue structure
The user can “containerize” the Operating System of choice (must be a Linux-based OS) plus all the libraries and applications that are needed on his/her own, and then launch it inside a job. This gives the user the flexibility of “almost” an Infrastructure Service.
GREASY is a meta scheduler to simplify the execution of embarrassingly parallel simulations in any environment.
This service enables users to define, create and manage their own infrastructure. This mostly consists of raw resources like Compute (e.g. virtual cores), Storage (e.g. block devices) or Network (e.g. routers) – among others – that users can control via a REST-ful API. Users are then enabled to create their own services on top of it like web services or databases, among others.
Bidirectional data transfer services between /scratch and /store and between /store and any external location
