Term Definition
I/O System
Highly-scalable, parallel I/O will be an important building block for future Exascale systems. In the DEEP-ER project, the I/O subsystem relies on 3 components: Fraunhofers parallel file system BeeGFS, the parallel I/O library SIONlib, and Exascale10.

Programming code developed by the University of Leuven to simulate space weather.


Knights Corner is the code name of an Intel processor based on the MIC architecture. Its commercial name is Intel® Xeon Phi TM.


Knights Landing, second generation of Intel® Xeon PhiTM.


Intel Many Integrated Core architecture


MPI is short for Message Passing Interface, an API specification typically used in parallel programs. It allows processes to communicate with one another by sending and receiving messages.


NAM or Network Attached Memory, nodes are connected by the DEEP-ER network to the DEEP-ER Booster Nodes and Cluster Nodes providing shared memory buffers/caches. This is one of the extensions to the DEEP Architecture proposed by DEEP-ER.

NVM, short for non-volatile memory, is an innovative memory technology. In the DEEP-ER hardware architecture, the NVM device is physically attached to the Booster Nodes (BN) and provides local high-performance data storage. Thus, it adds another layer to the memory hierarchy in DEEP-ER.

OmpSs is the Barcelona Supercomputing Centre's Superscalar (Ss) for OpenMP. It is the programming model used in DEEP and DEEP-ER.

ParaStation MPI

ParaStation MPI is a software for cluster management and control developed by project partner ParTec.


Petaflop, 1015 Floating point operations per second


Demonstrator system for the extended DEEP architecture. It is based on second generation Intel® Xeon PhiTM CPUs, connecting Booster Nodes (BN) and Cluster Nodes (CN) via a single, uniform network and introducing NVM and NAM resources for parallel I/O and multi-level checkpointing.


SIONlib is a parallel I/O library that enables large-scale parallel applications to perform efficient parallel I/O to task local files. The software is developed by project partner Jülich Supercomputing Centre.
