G-Station advantages:
- Dramatically accelerate applications
- No need for air conditioning or controlled environments
- Avoid fans and noise thanks to hot liquid cooling
- Save on energy bills thanks to the world champion in energy efficiency
- Replace your workstations hosting up to 160 users in a box
- Centralize departmental IT resources
- Reduce space occupancy with the most dense HPC system in the market
Powerful
Aurora G-Station is able to perform at 21 Tflop/s per rack. It has very fast Infiniband QDR interconnects.
Silent
The Aurora G-Station is water cooled, so it produces very little noise.
Modular
From 1 to 8 double socket double GPU blades in a single unit. More units can be connected together.
Scalable and easy
The G-Station doesnt have complicated and messy cabling and it easily scales joining more modules together.
Compact
Remarkable density, storing 16 powerful Xeon processors and 16 Nvidia Kepler GPUs or Intel Phi in a 65cm (or 95cm with incorporated heat exchanger) rack.
Energy efficient
Aurora G-Station marks a record in energy efficiency with over 3.2 GFlop/s per Watt.
Reliable
No moving parts eliminate vibrations. Direct water cooling avoids hot spots while the soldered memory provides speed and robustness.
Water cooled
All computational nodes (CPUs, coprocessors, memory, board) in the Aurora G-Station are water cooled, without the need of an expensive infrastructure to be deployed. All heat can be taken out of the room just as with a split air conditioner.
Architecture
Each G-Station mounts 1 Aurora HPC 20-22 chassis with 8 slots. Each chassis provides electrical, network (IB 40 Gbps) and liquid connections and mounts up to 8 Aurora HPC 20-23 blades.
