KIFÜ has been operating its supercomputer infrastructure since 2001. The components of this infrastructure (computational and data storage facilities) can be found in 5 locations. Leo, our most powerful HPC site, is a cluster type machine located in Debrecen, the second largest city in Hungary. The overall processing power of the 1344 CPU cores and the 252 GPUs is around 254 Tflop/s. Concerning the storage capacity, a total of 585 TB can be used for computational purposes.

More than 380 projects have used the Leo cluster so far, and nearly 850,000 tasks have been submitted since its start. Approximately 70 disciplines have been registered over the years. Theoretical/computational chemistry, biology, and physics dominate resource allocations.

Any person or research group whose host institution has a contractual relationship with KIFÜ can use the HPC facilities. Such institutions are typically universities, the Hungarian Academy of Sciences, museums, and special libraries. They can use the HPC infrastructure free of charge.

The name Leo was chosen to pay homage to Leo Szilárd, a Hungarian physicist and inventor, although the name simultaneously refers to the lion, which symbolises strength and courage.
