High Performance Computing (HPC)

High-Performance Computing (HPC) is defined as an ability of a computer system to process large-scale data, and to perform complex calculations at super high speeds. HPC parallelizes sequential codes into multi-threaded codes and run them simultaneously on multiple processors and shared memory via Message Passing Interface (MPI) in order to result the super high speed computing power in combined.

VYROX consults and deploys HPC solutions for universities and institutions. we engineer, supply, and install for laboratories of research, development, and test. Overall, VYROX has three types of HPC solutions at different level of costs that designed to fit to your budget and requirements. Beside the HPC machines, VYROX designs also the key HPC engineering requirements like power, cooling, ventilation, ELV, network, IoT-based security, and safety for an efficient, scalable, and flexible HPC/supercomputer/server rooms.
