India’s first computer

The 1950s-70s

N Dayasindhu, May 19, 2023: The Times of India

IBM 1620 arrives at IIT Kanpur in 1963
From: N Dayasindhu, May 19, 2023: The Times of India

The first Indians to undergo training on computers were probably professors Amresh Roy and Monimohan Mookerji of the Indian Statistical Institute (ISI) in Kolkata in the mid-1950s. ISI purchased a HEC2M made by British Tabulating Machines (BTM) and designed by Andrew Booth at Birkbeck College London. The Indian professors trained with Booth on how to program and maintain this computer. BTM felt it would sell only one computer in India, and it was not economically viable to station their service team in India.

In the 1960s, many young scientists recruited for India’s nuclear energy and space programmes were trained on the indigenous TIFRAC computer built by the Tata Institute of Fundamental Research (TIFR). Abdul Kalam, who became the President of India, recalled that one of his first assignments when he joined the space programme was to work with the TIFRAC team. TIFR’s and Bhabha Atomic Research Centre’s capability in computer hardware were instrumental in setting up a public sector company, Electronics Corporation of India Ltd (ECIL). The TDC 12 from ECIL was India’s commercially produced computer.

The first programmes to build Indian capability in high-level programming probably began in the early 1960s in IIT Kanpur. Since they were set up with US support, faculty from leading US universities visited IIT Kanpur to set up labs and teach. An IBM 1620 computer arrived in IIT Kanpur in 1963 and was among the first computers in India that could be programmed with a highlevel language like Fortran. The visiting American faculty along with the now legendary Indian fac- ulty, V Rajaraman and H N Mahabala, set up the IIT Kanpur computer lab and devised a ten-day course. The course covered Fortran programming, numerical methods, and introduction to computer architecture. This was open to professionals in government and industry. F C Kohli, the first CEO of TCS, attended this course.

The first course in programming for undergraduate students was the TA (Technical Arts)-306 in IIT Kanpur. Abhay Bhushan, an IIT Kanpur student of this era, went on to write the original specification for the seminal File Transfer Protocol while at MIT. In the mid-1960s, IIT Kanpur introduced the MTech programme in electrical engineering with a specialisation in computer science. N R Narayana Murthy, the founder of Infosys, is a graduate of this programme.

With the growing interest in programming in India, Rajaraman’s lecture notes were published as the book ₹Principles of Programming’ in the late 1960s. The publisher printed it on newsprint since the author insisted that the book should be affordable to students. IIT Kanpur went on to start one of India’s first undergraduate BTech courses in computer science in 1978.

In 1978, the department of electronics set up a manpower development committee headed by Rajaraman that recommended a new academic programme called the Master of Computer Applications (MCA), as a post BSc qualification. This improved the job prospects for young Indians with a BSc degree and provided a boost to the supply of trained IT professionals. A famous graduate of the MCA programme is N Chandrasekaran, who was the CEO of TCS and is now the chairperson of Tata Sons.

Mahabala moved to IIT Madras in the early 1970s to set up the computer science department there. IIT Madras got an IBM 370, which was one of Asia’s most powerful computers in that era and started an MTech programme in computer science. IIT Madras encouraged students with an MSc degree to enrol. This provided an opportunity for Kris Gopalakrishnan, co-founder of Infosys, to pursue this MTech programme.

The 1970s


In-company training programmes evolved from the early 1970s when TCS invited the faculty of IIT Kanpur to teach computer programming to their college recruits. Later, they invited H N Mahabala to set up a training programme on programming and systems design and this became the foundation for the industrial scale in-house training programmes for fresh college recruits in TCS. A pinnacle of Indian IT’s capability building is Infosys’ Global Education Centre in Mysuru. It rivals the campuses of the best universities in the world in terms of its state-of-the-art learning and recreational facilities, and can simultaneously train about 13,500 professionals.

HCL and its precursors

Ajai Chowdhry, June 16, 2023: The Times of India

For years, the Indian computer industry has had arms swinging in both directions, hardware and software. The big boys of the Indian computer scene have been adept at both. It may come as a surprise to many that some of the leading software companies of today actually started out as hardware firms or had a hardware connect. The birth of Infosys, for example, can be traced to Mumbai-based Patni Computers, which used to be a distribution company for Data General (one of the first minicomputer firms of the late 1960s in the US).

Founder Narendra Patni became one of the early software exporters when he started getting business for software. In 1977, Narendra Patni appointed NR Narayana Murthy to head the software division. Murthy left Patni Computers in 1980 along with six colleagues to found Infosys. Just like Murthy, other Infosys co-founders, including Nandan Nilekani and Kris Gopalakrishnan, too have a hardware connect, having started their career at Patni Computers. 
Hinditron, founded in 1966 and now into software, telecom and more, too started with selling digital hardware and PCs. Harish S Mehta, co-founder of Nasscom, was in hardware initially. Tata Burroughs was formed following a collaboration between the Tata Group and Burroughs in 1977. While Burroughs was among the largest computer manufacturers in the world, its joint venture with TCS opened for Tatas many global opportunities including TCS’s first big IT outsourcing contract – to upgrade a hospital accounting system for about $24,000.

HCL too has its origins embedded in hardware. We had set up a hardware manufacturing plant in Silicon Valley, US. But due to a US government specification, that hardware could not be supplied, and a large loan from ICICI Bank became a question mark. The product that we wanted to sell in America was a multiprocessor – a Unix-based minicomputer. The OS we created for this multi-processing hardware was absolutely unique – a fine grained Unix, the first in the world. Since we could not continue with the hardware business in America, we pivoted towards software, strengthening our R&D base. Our Unix capability led us to the software business. Wipro too moved to software because of its hardware capability. That’s how our homegrown firms started competing with biggies like Accenture and Capgemini.

Today, all the top names in theindustry carry out engineering and R&D exports, where the knowledge of hardware and embedded software is used to create products for global markets. There is also development of semiconductor chips. 
The kind of skills we created opened the paths for software businesses. At HCL, we started our Singapore subsidiary in 1980 to manufacture computers. The market was like in India, but also wanted solutions. This meant providing also the application software, such as for finance and accounting, sales order processing, inventory control. So, to support the hardware business, we started a software export division in Madras (now Chennai) in 1980. We were amongthe earliest to do software in India for global companies.

Back in the day, we would carry out a system study of the requirements of our Singapore customers and send back the system report to our software export division in Madras, that created specialised tools. Those were very early days in the automation of the whole process of programming, to export the software faster. Today, there’s a lot of talk about automating software, but we did it in 1980, when communication links left much to be desired. We would make the software and courier the floppy disks, which would often get corrupted due to Customs’ x-rays. The process would painstakingly be repeated to get it sent to the customer.

A lot of capability got built and honed over time as a result of designing and making our own software and hardware. We created our own word processing software, our own relational database, much before Oracle did! We realised early on that building our own skill capital would lead us to long-term sustainability.

Given the exploding demand for electronics now, all these skills will help us in becoming the product capital of the world, backed by favourable geo-politics.

Supercomputers and India

PARAM 8000: India’s first Supercomputer

India , A home-made , super-duper supercomputer 15/12/2016



A home-made, super-duper supercomputer

The PARAM supercomputer began its life as a result of a technology embargo that had been placed on India. As the story goes, in 1987, during a high-technology meet between India and the US, the then US president Ronald Reagan refused to sell to then prime minister Rajiv Gandhi the latest CRAY supercomputers being developed in America. Instead, the Indian premier was offered an outdated machine, and also warned against its use for any purposes other than weather forecasting. This was not without good reason-supercomputers are an essential step toward modern weapons systems. For example, the calculations required to construct an intercontinental ballistic missile cannot be performed on an ordinary computer; it would take far too long. In 1988, for the purposes of developing self-sufficiency in such matters, India established the Centre for Development of Advanced Computing, or C-DAC, with Dr Vijay Bhatkar as director. With a deadline of three years, and a budget of around Rs 30 crore, PARAM 8000 was born in 1991.

Pune supercomputers among world’s fastest

Swati Shinde Gole TNN 2013/06/20

The Times of India

Pune: Two computers from Pune feature among the top 100 in the list of 500 fastest supercomputers in the world.

While the Indian Institute of Tropical Meteorology (IITM) supercomputer stands 36th in the list, Param Yuva II, developed by the Centre for Development of Advanced Computing (C-DAC), has bagged the 69th position. The IITM supercomputer is yet to be installed while the Param Yuva II became operational this February.

The list of the world’s top 500 supercomputers was announced on Tuesday at the launch of the opening session of the International Supercomputing conference in Leipzig, Germany.

The Param Yuva II has a capacity of 524 teraflops and within three weeks of the launch, it was already running at 70% of its capacity. Precise weather forecasting, faster tapping of natural resources in the sea and designing of customized drugs are possible using Param Yuva II. The IITM supercomputer will start functioning in the next two to three months.

2016: India ranked 9th in global race for supercomputers

What is a supercomputer?

Supercomputers are broadly defined as the fastest computing systems at any given time and are used for scientific purposes that require handling of troves of data at high speed. This includes testing mathematical models using thousands of variables to infer complex phenomena like weather, climate change, nuclear reactions, origin of the universe and so on.

How is the computing power of a supercomputer measured?

The standard unit to measure computational power is FLOPSfloating point operations per second. It is the number of mathematical operations involving fractions that a computer can do per second. For the most basic computers and smartphones, the computational ability is a few megaflops (more than a million operations per second). Chinese supercomputer Sunway TaihuLight -which is ranked the fastest in the world by Top500 (a supercomputer ranking project) -has a computational ability of 93 petaflops, more than a billion times faster than normal computers. Recently it was announced that Japan will spend $173 billion to bu ild the world's fastest supercomputer system with a capacity of 130 petaflops.

What problems were faced by supercomputer pioneers who worked to enhance computer speed?

First, the maximum speed at which electronic signals can travel cannot be faster than the speed of light. Second, because of frequent receiving and transmission of these signals, it was important to have a suitable cooling technique to control the temperature of the system. Both barriers were tackled by decreasing the lengths these signals were re quired to traverse by using circuit boards and innovation in cooling techniques.Other advancements involved introduction of vector arithmetic in computing.

When was the world's first supercomputer built?

In 1965, CDC 6600, a supercomputer designed by US engineer Seymour Cray was installed at the CERN in Geneva, Switzerland. CDC 6600 had a computational capaci ty of three megaflops. In the 1970s, the series CDC 7600 was introduced, which was10 times faster than the earlier version. In 1976, the Cray-1supercomputer was installed in the Los Alamos laboratory with a computation capacity of 160 megaflops.

What were the limitations of Cray's designs?

Cray's designs used expensive technology and liquid immersion technology to achieve high speeds. W Daniel Hill, an MIT graduate proposed a decentralised control instead of one CPU, which meant several inexpensive processors could be arran ged to achieve speeds comparable to the most expensive supercomputer designed by Cray. Hill designed the CM-1 in 1985, which used thousands of inexpensive processors to achieve the same speed as Cray's computer.

Which countries are the world leaders in supercomputers today?

Of the 500 fastest supercomputers, the highest numbers are in the US and China, each having 171 such systems. Germany , Japan and France each have 20 or more such systems. India is ranked 9th with five of its supercomputers listed in Top500.

As in 2020

Meet Pratyush and Mihir, India's two supercomputers among the world’s best, June 24, 2020: The Times of India

Every year the list of fastest supercomputers comes out. Published by TOP500, the list this year features two supercomputers from India once again. Pratyush and Mihir, the two supercomputers of India, ranked in at 67th and 120th spot on the list. These rankings were announced on June 22 at the ongoing virtual event ISC (International Supercomputing Conference) High Performance 2020 Digital.

The two Indian supercomputers’ rankings, however, has fallen down compared to last year. According to the 2019 rankings, Pratyush supercomputer was in 57th spot whereas Mihir supercomputer’s ranking was 100. The TOP500 list is a project that regularly ranks and evaluates the top 500 fastest supercomputer systems in the world.

Prathush is India’s fastest supercomputer with 3.7 petaflops high performance. The supercomputer is at the Indian Institute of Meteorology, Pune.

For the uninitiated, a petaflop is the measure of a computer’s processing speed. A petaflop is equal to a quadrillion or a thousand trillion calculations per second.

Mihir, which was ranked 120th, had a capacity of 2.5 petaflops. This particularly fast machine is at the National Centre for Medium Range Weather Forecast in Noida.

The two supercomputers were installed in 2018 by the ministry of earth sciences. The estimated cost of installing and setting them up was close to Rs 440 crores, according to an earlier report by The Economic Times.

The two supercomputers are used to help the quality of not just weather forecasts like monsoon but also of cyclones, earthquakes and other extreme events. They can also help forecast air quality, flood, drought among other things.

As for the fastest supercomputer in the world, that title was accorded to Fukagu, a Japanese system backed by Fujitsu and RIKEN. For comparison sake, Fukagu had a performance of 415.53 petaflops. The list, otherwise, was dominated by a lot of supercomputers from China and the USA.
