As we enter the exascale era, supercomputers get bigger, denser, more heterogeneous, and increasingly complex.
Reliable and efficient operation of such machines requires in-depth insight into the operating parameters of the machine and its supporting infrastructure.
To meet this need and to enable continuous monitoring, archiving and analysis of near real-time performance data from the machine and infrastructure levels from both the maintenance and user perspectives, tailor-made measures are needed .
This is all the more true for Leonardo, the supercomputer officially inaugurated on 24 November 2022 in the presence of the President of the Italian Republic, Sergio Mattarella, as well as the flagship of the Emilia-Romagna Data Valley, centered on the new Big Data Technopole infrastructure.

The Emilia-Romagna Data Valley is increasingly a tangible reality…

Feasibility tests on current calculators in Casalecchio di Reno such as the Marconi 100

We worked in collaboration with the University of Bologna to implement an operational data analysis infrastructure: it was tested on the current CINECA supercomputers such as the Marconi 100.
The CINECA Visit Lab team is working on a 3D model of the machine and of the physical place where it will be installed.
The work began by acquiring information on the technical layout with placement of racks, cooling system devices and so on.

A Digital Twin in Virtual Reality very useful for management and communication purposes

The goal was to develop a three-dimensional model that was useful both for management purposes, but also for communication purposes.
The model will be very useful for creating the 3D interface for a Leonardo digital twin.
In particular, the Visit Lab team has developed a workflow for the construction of 3D Digital Twins with VR, where the focus is on the interaction with the virtual model and on the simple reusability of the developed framework which acts as a back -end.

Five aspects already used for highly portable data centers and adaptable to other fields

The implementation and design, already conceived for supercomputing data centers, are highly portable and adaptable to other fields.
The proposed workflow focuses on some of the main aspects of implementing a digital twin, namely: automated modeling; connection between physical entity and virtual model; connection between virtual model and services; connection between virtual model and data; interaction between virtual model and users.

The Technopole turns on the super computer to light up the future

The first main element: the "data lake" implemented by the Alma Mater Studiorum

Right now this infrastructure has two main components centered around data and data visualization.
The first element is the "data lake" produced by the Exascale Monitoring Infrastructure, i.e. ExaMon, implemented by the Alma Mater Studiorum as part of the European IoTwins project, together with an ES CINECA data lake which collects information on the use of the machine by of users and projects.
In particular, ExaMon collects different heterogeneous data, both hardware and software, and exposes different tools to consume the telemetry data such as Python APIs and data formats for various analysis frameworks.

The second major element: several open-source applications, all based on the web

The second consists of several web-based applications that offer different types of insights into the data, depending on the end user.
These web applications are both 2D and 3D and are based on open-source frameworks such as React: the latter is used for creating 2D interfaces, Blender and Verge3D used for creating 3D interfaces and Grafana, used for visualization and exploration of metrics.
The 3D model of the Leonardo supercomputer will be available soon.
