EGI in numbers: from small steps to giant leaps

Alessandro Paolini and Vincenzo Spinoso review the figures from the last years

Over the last 15 years, EGI has been supporting science at all scales, from individual researchers to research infrastructures and large collaborations, by offering computing resources throughout Europe and worldwide. We have been monitoring the evolution of the EGI e-Infrastructure since the start of the EGI-InSPIRE project, through the period of EGI-Engage and now in EOSC-hub times.

This article highlights a couple of the trends we have recorded. Of particular note is the 1,000,000 federated cores milestone which was reached earlier this year, marking a decade of continued growth.

We are now looking forward to the 2 million core mark!

Installed compute capacity
(number of cores), 2011-2019

The number of cores installed on the data centres of the EGI Federation has consistently increased since the current measurement system was implemented in 2011, during the EGI-InSPIRE project.

The federation crossed the 1,000,000 cores milestone earlier in 2019.

Storage capacity,

The EGI Federation offers online storage (in disk) and archive storage (on tape) to meet requirements for data sharing. The available capacity has been increasing steadily and today is 696 Petabytes. The capacity for archive storage decreased slightly in 2019 due to the decommissioning of the service on a specific data centre.

User distribution per field,

The number of users of the EGI Federation has been increasing steadily over the years. The highest increase was recorded in the Humanities field.

Consumed HTC resources,

This graph shows the years of not normalised wall-clock time consumed by jobs, multiplied by the number of logical cores used by the job. This gives a measure of how much resources are consumed. In total, since 2011, EGI users have consumed 2,3 million years of CPU time.

Cloud statistics, 2015-2018

The EGI Federated Cloud was launched in 2014 and went into production in 2015. Since then, cloud users have ran 1.9 million Virtual Machines (VMs) and consumed a over 10,000 years of compute time.

The decrease in 2016 is due to an accounting problem corrected in 2017.
