Introduction of FX10 Supercomputer System
On April 2nd, 2012, Supercomputing Division, Information Technology Center, The University of Tokyo (SCD/ITC/UT)started its new supercomputer system (FX10 Supercomputer System (Oakleaf-FX)).
Oakleaf-FX is a Fujitsu’s PRIMEHPC FX10 massively parallel supercomputer with a peak performance of 1.135 PFLOPS. Oakleaf-FX is the first system, which is installed to a new building of ITC/UT in Kashiwa campus of the University of Tokyo.
The new system is named after the area (Kashiwa-no-Ha = Leaves of Oak Trees) of Kashiwa campus.
Oakbridge-FX (Fujitsu PRIMEHPC FX10, 136.2 TFLOPS) was installed to ITC/UT in Asano Campus and started on April 1st, 2014.
On Oakbridge-FX long-term job (maximum one week) can be run.
