System overview

This section provides an overview of the MeluXina infrastructure, including system architecture, components and networks.

Gaining access

Learn about possibilities for obtaining access to MeluXina, the access process, and managing your resource allocations.

First steps

If you are new to using an HPC system or to MeluXina, this section covers the essentials: connecting to the platform, data transfers and running applications. More in depth topics can be found in the dedicated HPC and our HPDA sections.

HPC

HPC power users will find here additional information about MeluXina and its environment enabling an efficient and effective utilization of the platform.

HPDA

High Performance Data Analytics sits at the cross-roads between Data Analytics and High Performance Computing. This section will help data scientists and data engineers to take advantage of MeluXina for data-driven workloads.

FPGA

Designed for compute acceleration, Meluxina's FPGA nodes have two 520N-MX PCIe board featuring Intel’s Stratix 10 MX2100 FPGA with integrated HBM2 memory. The size and speed of HBM2 (16GB at up to 512GB/s) enables acceleration of memory-bound applications. These cards can be programmed using the Intel® FPGA SDK for OpenCL and/or the Intel® oneAPI software development toolkit.

Platform events

Platform status and events are announced to the users through the MeluXina Weather Report system.
Planned events are communicated in advance through this system and also the Message of the Day (MOTD) on MeluXina Login nodes.
