Sesterce Campuses. 6 principles.

The highest bar ever set for a supercomputer. The same in every country.

  • The supercomputer building at Bosquel, clad in timber and metal, behind birch trees.

    Architecture

    Designed by award-winning architects.

    A campus you are proud of, not one you try to hide. We give it the care usually reserved for a public building.

  • The curved living building at Bosquel, with timber balconies.

    Living

    A supercomputer and a living building.

    Every campus pairs the supercomputer with a living building: hotel rooms, restaurants, training and education, open to residents.

  • A solar power plant among green fields, seen from above.
    1:1

    Energy

    New renewable power plants, one for one.

    For every megawatt a campus consumes, we build one megawatt of new renewable generation on the same grid, within ten years. New plants, not certificates.

  • Rain falling on the surface of water.
    100%

    Water

    Cooled by rain and recycled water.

    Direct liquid cooling in a closed loop. Every liter that tops up the loop comes from on-site rainwater and used water we filter and treat.

  • Construction workers in hard hats and high-visibility vests on a building site.
    3per MW

    Jobs

    Jobs that stay local.

    Three local jobs per MW while the campus is being built, and at least one long-term job for every 2 MW consumed.

  • Neighbors sharing a long dinner table in the street of an old town, under festive flags.
    €10M

    Community

    A fund for the town.

    Paid at commissioning. The municipality spends it locally, on what improves life for the people who live there.

“We want the places that host our supercomputers to be better off for it. That is why every campus is built on these six principles.”

Youssef El Manssouri, Co-founder and CEO, Sesterce

Supercomputers

We build the supercomputer. You run the models.

Dedicated bare-metal clusters, built with Sesterce Modular Design and run by Sesterce OS.

Sesterce Modular Design

Built in the factory. Connected on site.

Power distribution, backup power and cooling are standard modules. We assemble them in the factory, ship them to the campus and connect them to the building. We own every hand-off, from watt to token.

Module by module. New capacity is added as demand grows.

Bare metal, run by Sesterce OS

A dedicated supercomputer. Run by Sesterce OS.

Dedicated hardware, network and storage, with root access and out-of-band management on every node. Sesterce OS runs the campus around it, from the grid to the chip. It watches every hall, the power chain, the cooling loop and every node, and recommends what to do next.

  • Root access
  • Out-of-band management
  • Single tenant
