Since 2017, The Hypercube has been performing detailed airflow simulations and implementing numerical optimization procedures. These methods require significant computing power, which until now has been provided by "virtual machines" in Microsoft's Azure cloud. The team thus had 24 bodybuilt "machines" (8 ultra-clocked logic cores and 56 to 112 GB of RAM), switched on on demand and allowing a high reactivity.
This solution, which has been in use for 2 years, limited us in terms of reactivity (IT maintenance) and connectivity (data transfer speed) with a non-negligible associated cost.
The question then arose, with the AREP IT team, of an opportunity to invest in an "on-premises" calculation server... It is now done! It has just been delivered, in kit form.
It is therefore a computing rack with 4 processors, 20 cores each capable of hyperthreading (virtualization of a second core), in other words, 160 cores dedicated to simulating building physics phenomena! This represents the equivalent of more than 25 high-performance computers (for example for 3D visualization).
Today, this "beast", with 256 GB of RAM memory, extensible up to 3TB, runs on the open source Linux operating system (Debian 9).
Many thanks to AREP IT Services for their advice, support and energy!
