•use parallel
supercomputers
–access to tens/hundreds of CPUs
e.g. NOTUR/NTNU = embla
(512) + gridur (384)
–high speed interconnect, shared memory
–usually for batch mode processing
–very expensive (price, maintenance, upgrade)
–these CPUs are not so powerful anymore
e.g. 500 MHz RISC vs.
today's 2.5 GHz Pentium4
