Supercomputers: Evolving Capabilities Through Technology!

Author: Sherazur Rahman

Research into computers began extensively in the early 20th century, but the first practical programmable computer was not developed until during World War II. In the United States, the ENIAC (which stands for Electronic Numerical Integrator and Computer) was built, mainly for military use. The work on the ENIAC started in 1943, was finished in 1945, and was then officially launched in 1946.

From ENIAC to CDC‑6600: The Dawn of Supercomputers

The United States then, drawing on that experience, brought out the world's first successful commercial supercomputer in 1964; the CDC−6600, which was designed by the well-known computer scientist Seymour Cray for the Control Data Corporation, represented a revolutionary milestone in the history of computing.


The CDC-6600 had about 400,000 transistors and almost 100 miles of wiring; it weighed approximately 6 tons, needed 30 kilowatts of power, and was equipped with a 60-bit processor operating at 10 MHz. Its maximum memory capacity was 982 KB and it could carry out about 3 MegaFLOPS, which meant that it executed nearly 3 million instructions each second.


It introduced the idea of superscalar processing, which allowed several instructions to be carried out at the same time. Cooling was achieved using a special Freon refrigerant system, and the operating systems it used were SCOPE and KRONOS. Although the computer was very expensive at a cost of USD 2.37 million, over 100 units were sold around the world for use in nuclear research, weather forecasting, and the carrying out of complex scientific calculations. It held the title of the world's fastest computer from 1964 until 1969, when it was surpassed by the CDC‑7600.


The Modern Era of Supercomputers:

In the 21st century the rivalry in the field of supercomputer design has become greater. The most powerful supercomputer in the world is LineShine, which is based at the National Supercomputing Centre in Shenzhen, China. It has reached an unprecedented Rmax figure of 2.198 ExaFLOPS and thus becomes the first CPU-only system to go beyond the 2-ExaFLOPS mark.


Other prominent systems are El Capitan (USA, 1.809 ExaFLOPS), Frontier (USA, 1.353 ExaFLOPS), Aurora (USA, 1.012 ExaFLOPS), the JUPITER Booster (Germany, 1.00 ExaFLOPS), and Fugaku (Japan, 442.01 PetaFLOPS).


In the Middle East, the Shaheen III supercomputer at the King Abdullah University of Science and Technology is in 22nd place and has a performance level of about 122.8 PetaFLOPS; the Shakti Cloud, which is operated by Yotta Data Services in India, comes 32nd worldwide with 84.31 PetaFLOPS, and India's indigenous AIRAWAT-PSAI achieves 8.5 PetaFLOPS and is ranked 211th.


Bangladesh’s Emerging Efforts:

Even though Bangladesh hasn't yet acquired a national supercomputer, there are already a number of advanced computing labs and AI infrastructure systems in place. In particular, the American International University-Bangladesh (AIUB) has set up the nation's first modern AI supercomputing lab, it consisting of 40 NVIDIA DGX Spark units, which are used for advanced research and AI development.


Conclusion:

Nowadays, supercomputers play a vital role in matters of global security, in the simulation of nuclear weapons, in scientific research, in space exploration, and in the field of artificial intelligence. Nevertheless, the simple CDC-6600 from the middle of the 20th century formed the basis for this technological revolution and is still a lasting symbol of the history of modern computing.
