National Museum of Science and Technology receives first piece of Spain's largest supercomputer

• Supercomputing Center of Galicia, CESGA, under the Government of Galicia and the CSIC MUNCYT donates a piece of a CPU from a 1993 supercomputer.
• The supercomputer was a powerful calculating machine capable of solving 2,500 million operations per second
• The piece will be located in Room XX century of the museum that opens in June

On Friday April 12, the National Museum of Science and Technology, MUNCYT, received the first piece of Spain's largest supercomputer installed at the Supercomputing Center of Galicia, CESGA in 1993. King Manuel Varela, Director of Innovation Galega Axencia the Ministry of Economy and Industry of the Government of Galicia and President of CESGA, and Javier García Tobío Managing Director at CESGA, gave this piece to Centella Ramon Nuñez, Director of MUNCYT at 1 pm in the museum auditorium.

This is a FUJITSU VP2400, a vector uniprocessor that was installed in the most powerful supercomputer in Spain in 1993. This powerful calculating machine, which in that year was in the 146 position among the world's fastest in the TOP500 LIST, was able to solve 2,500 million operations per second. It was the first supercomputer Fujitsu installed in Europe. Its most important feature is that it was able to operate with two vectors of up to 2,048 items in double precision. Simultaneously performing two operations, multiplication and addition, simultaneously. The clock frequency was 312.5 MHz and was 8 operations per cycle.

The central processing unit (CPU) of this supercomputer was cooled by a closed water circuit. The available system memory 512 MB SRAM, 1 GB of solid state memory (SSU), 15 GB disk. This configuration occupied 75 square meters, weighed 7.986 kg and dissipated 48.428 kcal / h.

The piece CESGA MUNCYT donates is one of four CPU modules and incorporates VLSI (Very Large System Integration technology. This vector processing unit is presented on a multilayer ceramic substrate plate of high density (up to 61 layers), the first job in which said substrate is globally, instead of the hitherto conventional ceramics and aluminum, obtaining and a faster signal propagation.

The Fujitsu VP2400, which was installed and operational in the Supercomputing Center of Galicia between 1993 and 1998, was used by researchers from the Galician Universities and National Research Council, CSIC. It was used to develop models and simulations in multiple disciplines emphasizing its use in areas related to theoretical chemistry (molecular modeling and dynamics) or fluid dynamics.

It was also used by industry in collaboration with research groups of public entities. For example, ENDESA used it to simulate the behavior and dispersion in the atmosphere of the plume of pollutants from smokestacks of power plants.
