Turkish scientists, working under difficult situations compared to their foreign colleagues, have managed to achieve international success in the field of high-speed high-power computing.
Bilkent University Computational Electromagnetics Research Center (BiLCEM) has solved the largest integral-equation problem in history, breaking a world record. Project leader Professor Levent Gürel and his team managed to solve a problem with 33 million unknowns with a parallel computing platform that they prepared the hardware and software for. This system makes very high-level modeling possible.
The simulation system will contribute to development in the defense and health industries. This breakthrough will enable BiLCEM researchers to solve larger and more meaningful real-life problems.
The previous record was broken five years ago by scientists at the University of Illinois who managed to solve a problem with 22 million unknowns. The breakthrough will be presented in the upcoming 2007 IEEE (Institute of Electrical and Electronics Engineers) International Symposium on Antennas and Propagation, a major worldwide conference on electromagnetics to be held in Hawaii June 10-15.
The BiLCEM team has worked on the project for a long time. Unable to reach high-capacity computation levels due to insufficient means, the team instead devised software to construct parallel computing platforms.
BiLCEM teamed up with Intel Corporation and Intel made its parallel computing platforms in England available to the BiLCEM researchers over the Christmas and New Year holidays. "The company let us use the computers for a week while they were on holiday. We worked day and night," BiLCEM head Gürel said. They linked the computers together through multiprocessors, reaching a memory capacity of nearly 250 gigabytes, Gürel said. Computers with this much memory cost millions of dollars, yet this system cost only about $150,000.
Their breakthrough will help solve bigger problems. The system aims specifically to be used in the defense and health sectors. The high-level electromagnetic modeling system will enable a developed radar analysis of the airplanes, allowing airplanes and ships to go undetected by radar.
Another area explored by BiLCEM researchers is the electromagnetic modeling of complicated nano-optical imaging systems involving laser beams, lenses and chips of nanostructures. One of the biggest goals of the system is to see the influence that mobile phones have on human health.
Levent Gürel said the kind of reaction the human brain gives to the electromagnetic waves is unknown under normal circumstances. "The interaction of electromagnetic radiation with living organisms, where it is mostly seen, what highest values they reach and whether it is harmful or not must be clarified. Since measurement methods in living bodies are extremely limited, this needs to be done by means of computational simulations," he explained.
