Bangalore: Hewlett Packard (HP), the world’s biggest maker of personal computers, on Friday said that a total of eight entries in the list of top 500 supercomputers are from India and six out of the eight entries are from HP. Among vendors, HP leads the list with a 41.8 % share of the systems, followed by IBM (37%), Dell (4%) and Cray (4%).
Supercomputer Eka, a HP-based system with a performance of 132.8 teraflops (floating point operations per second) has been ranked at number 13. Eka belongs to the Tata Group’s Computational Research Laboratories.
The rankings are released twice a year by researchers at the Universities of Tennessee and Mannheim, Germany, and at NERSC Lawrence Berkeley National Laboratory. The HP-based Param cluster of the Centre for Development of Advanced Computing has been ranked 68th.
The other supercomputers by HP from India are for an industrial research company (334), a research agency (428), IIT-Madras (436) and Paprikaas Interactive Services (478).
The two other supercomputers from India out of the eight in the list include IBM’s eServer Blue Gene Solution for Indian Institute Science ranked at 213 and a supercomputer for Digital Media Company (G) ranked at 481.
IBM’s Roadrunner has been ranked as number one in the list. The system, only the second to break the petaflop barrier, posted a top performance of 1.059 petaflops. One petaflop represents one quadrillion floating point operations per second.
