Abstract :
SUPERCOMPUTING has long been regarded as a high-end technology for the big users with big applications and big processing needs. However, suppliers of supercomputers - or high-performance computing (HPC) - are now targeting a much wider audience, using a mixture of cheaper and more powerful hardware, sophisticated new system architectures, and software that allows resources to be shared or even rented online. Their overall aim is to reach users who might use one occasionally, but cannot afford a supercomputer of their own.
