High-performance Computing

The NCHC provides many kinds of highly stable and efficient computing facilities for Taiwan's government, academia, and industry.

Computing is the foundation of scientific research. As Taiwan’s only national-level supercomputing center, we provide HPC services to science, research, and other interdisciplinary fields. We plan the assembly of advanced computing mainframes, high-efficiency PC clusters, and various engineering and scientific application software and databases. These resources provide domestic researchers a fast and stable HPC environment.

ALPS Taiwan's Largest Open Supercomputer

The Advanced Large-scale Parallel Supercluster (ALPS) or Windrinder, is a supercomputer built in May, 2011, that offers an aggregate performance of over 177 TFLOPS.

ALPS possesses a total of 512 general computing nodes, 32 large memory compute nodes, and over 25,600 cores. Each general compute node contains four AMD Opteron 6174 processors, and each large compute node contains four AMD 6136 processors as well as 256 GB memory.

Formosa 5 Cluster Taiwan’s Largest GPU-based Cluster System

Carrying on the heritage of the Formosa series, the NCHC continues to innovate by successfully building the Formosa 5 system-- the largest cluster computer in Taiwan designed specifically for GPU computing!
As demand for computing resources has steadily increased, so have the demands for new and different platforms and hardware. By taking advantage of many-core parallelism, the CPU working with the GPU has become the mainstay of HPC architecture. Formosa 5 is made up of 88 computing nodes, each equipped with two 6-core central processing units, three graphic processing units, and 96 GB of memory, all sharing an InfiniBand 40 Gbps high-speed network! After tuning, the NCHC's Formosa 5 achieved an optimal performance of 89.94 TFLOPS.
Formosa 5 began operations in August, 2012, and thus began providing Taiwan’s academic communities with the latest in GPU processing.

Formosa 3 Cluster – Taiwan's First Render Farm & IaaS Service Platform

Formosa 3 is the name given to the NCHC’s self-built cluster cloud computing and 3D rendering system. Combining the NCHC’s solid strength in cluster computing and cloud technology, it provides complete and reliable cloud computing and 3D rendering services.
Currently, Formosa 3 provides Infrastructure as a Service (IaaS), thus, offering its users virtual machine management, complete customization and control, and easy installation and integration.
Render Farm is the name given to the NCHC’s self-built 3D rendering machine. In order to provide complete services and exceptional rendering performance, the Render Farm cluster utilizes a Linux operating system as well as a professional rendering queuing system. Users are able to dispatch rendering jobs and monitor their computing status via a graphical user interface (GUI), whether using Linux, Windows, or Mac OS.
