The Institute of Mathematical Sciences (IMSc) here joined the worldwide Teraflop supercomputer club with the full commissioning of ''KABRU'', a 288-CPU (144 node) node Linux Cluster. ''With a theoretical peak performance of 1.382 Teraflops and a measured (sustained) performance of 951.7 Gflops of double precision arithmetical operations, KABRU is the second fastest supercomputer from India and the fastest supercomputer belonging to an academic/research organisation in the country, a release from the Institute said. The only other machine faster than this in the country was the 574-CPU cluster at Intel, Bangalore, which had a sustained performance of 1,105.96 GFlops and a peak theoretical performance of 2.755 Teraflops, it said. KABRU's entry had been accepted by the worldwide body ''Top 500'' for further evaluation, the release said, adding its design was based on Intel Xeon processors at 2.4 GHz, super-micro motherboard X5DPA-GG and networked with the very fast and low latency 3D SCI supplied by Ms Dolphinics of Norway. The supercomputer was integrated in a very short time and at a very low cost of Rs 2.5 crore. The design team was led by Prof N D Hari Dass and the feat was made possible by the extraordinary hard work of the engineers of Netweb Technologies, Delhi, and Summation Enterprises, Mumbai, the release added. The release said KABRU was designed as part of the Tenth plan project ''Indian Lattice Gauge Theory Initiative'' of the IMSc and would be mainly devoted to very large scale simulations of the properties of elementary particles as studied in an internationally active areas called Lattice Gauge Theory, the release said.
