Dear Leslie & Rediff people,

As usual, you have not studdied the subject & given article.

You are a big LOSER.

You dont know what to writr

HOTMAIL,GMAIL,ORKUT,INDIATIMES ,YAHOO are much better than
You are GONNA CLOSE YOUR SHOP

ALL THE BEST

Supercomputing Made Easy
by Sanal D (View MyPage) on Nov 16, 2007 09:05 PM

As everyone believes, supercomputing is not that difficult these days, especially in the lower computing speeds. This is all about parallel processing. If you know Linux, go to rocksclusters.com. Learn more about cluster computing. It will help you to learn, how mormal home machines can be combined together to do parallel processing and increase speed. This is something which even college students can try. This technology is widely used in rendering farms (Animation Studios)

Its not about who owns the components; its about who intelligently designs an architecture so advanced that it converts these ordinary retail components in something as priceless as a Supercomputer.
A supercomputer is not "assembled" at the backyard. It has a LOT of serious expertise going in it to make these thousands of retail processors and memory sticks(RAMs) work at dizzying speeds.Its not as simple as buy 1 lakh processors, add some terabytes of RAM and you have a fastest computer. If that was the case then anyone would spend billions of dollars and build a fastest supercomputer. It requires BRAINS to bring together these thousands of processors together and create something even close to a supercomputer.
P.S: If it would have been so simple as most of you think, then why didnt HP build this supercomputer? You think they didnt want to own the fastest supercomputer?No. the answer lies in architecture and design, which the TATA guys have applied.

go and get your basics cleared.
I know this field very well. The machine is an HP machine. Go to top500.org and read the top 500 list, and see the name of the manufacturer. The owner of the machine is mentioned as Tata Sons. The developer is HP.

If you understand some technical things then go into details and you will find that this machine has about 2000 nodes (HP servers) connected by Infiniband (a high performance network - not made by Tata). What CRL has contributed is the topology of connections.

Look at the cost 120 crores. C-DAC gets about 50 crores for a period of 3 years. And all that includes development and also the cost of building machines. No doubt they figured only once in this list.

if you had 200 crores and ready to spend it, you could top the list and IBM would build it for you.

and i don't mean to dis-regard work done by CRL.

These are very complex machines. It needs deep understanding to even maintain such machines.

It is a great step by Tata to spend this money which will ultimately benifit lots of scientists in the country. I am sure that is the ultimate aim of the Tatas.

what Ambanis doing. It is worth to have few TATAs than hundereds of Ambanis

Making a supercomputer is not the end of world. First understand the nunaces of the business then speak bout what Tata's and ambanis are doing. You think refining crude is a small and insignificant job????? Think again.

so confusing!

I find th supercomputer speed units very confusing.

In terms of average computer's units i.e. GHz, how many GHz is the world's fastest supercomputer capable of?

Ghz actyually means nothing, it is the clock speed at which the CPU is running. However it is the number of floating point instruction per second which gives true computing power. Say a typical PC may take around 8 cycles to complete a flop. So you know how many flops per second if you know the ghz. This is a rough approximation.
