China’s Tianhe-1 has a computing speed of 2,507 trillion（萬億）calculations a second, making it the fastest computer in the world．It is also 40 percent faster than the world’s second fastest supercomputer, Cray XT5 Jaguar, in the US, kept at a national laboratory in Tennessee, according to the New York Times．Jack Dongarra, a University of Tennessee computer scientist, told NYT that the Chinese supercomputer is faster than the existing Number One machine.

Building the fastest supercomputer has become a source of national pride, as these machines are valued for their ability to solve problems in areas like defense, energy and science．These problems are related to national interests．Supercomputing technology is also found in business．Oil and gas companies use supercomputers to find oil and gas．

Obviously, research centers with large supercomputers attract top scientific talents．This adds extra importance to the machines—they’re more than just huge computers．

China’s new supercomputer will be used to speed up greatly scientific calculations, such as hurricane and tsunami modeling, cancer research, car design and even studying stars.

In 2008, two US scientists put together a step-by-step guide on how to build a supercomputer using PlayStation 3 video-game consoles（控制臺(tái)）．Modern supercomputers are built by combining thousands of small computer servers（服務(wù)器）and using software to turn them into one large computer．Really, any organization with enough material and technology can create a fast machine．

The Chinese system follows that model by linking thousands upon thousands of computer servers．But the secret behind the system—and the technological achievement—is China’s own networking technology．“That technology was built by them,” Dongarra said．“They are taking supercomputing very seriously and using a lot of time and money.”

“China is still a developing country,” said Sha Chaoqun, manager at Dawning Company which is the leading supercomputer maker in China．“Maybe one day, China’s total computing power can be greater than that of the US, but there is still a long way to go before we get there.”

Mum，it’s me．Hopefully，this Mothering Sunday you will get to hear those three words．I will，of course，try to phone you．I hope we will be able to speak for the allowed 10 minutes．But I suspect many inmates will be using the phone，so if I don’t call and if we don’t speak，then this is what I would have said：

It’s not your fault that I am here．I know that deep in your heart you have questioned whether my current circumstance is somehow your fault，if the reckless stupidity of my past is somehow a failure on your part．It is not．Only one person is to blame，only one person should hurt — me．You have always taught me that when the room goes dark，you can wait for the lights to be switched back on or you can search in the dark and turn the light on yourself．You are my light．You always have been and always will be．There is nobody I admire more，nobody I have strived harder to please in my life，which is why my current failure hurts me so much．

I am so sorry that I will not be there to see you，but I want you to know that now，as always，you are here with me．In my darkest hours，and in the coldest loneliness of my past few months，my mind has so often wandered to the past，to when it was you and me — and I have been able to smile．Yours is the strength that I draw upon．

A parent’s job is to make sure that they pass on the best of themselves to their children．You have done that．It is the inner you in me that will get me through this．

I have failed you so epically，but you have never failed me．If I think back to the tears I shed when Dad left，all those years ago，I see you through their misty glaze．You holding me and you telling me we’d be OK，and we will be．We are and always will be the best team．

Childhood heroes such as footballers，actors and rock stars are clichéd． If the job’s done right，a child’s heroes should be their parents — you are mine．The strength you showed after the divorce from Dad to find your biological parents，to go to university and get your teaching qualifications，to begin your life again，is the strength that I draw on now．It is the belief in myself，it is the belief you have in me，that tells me that once I am released I can and will rebuild my life．I will make you proud again．I will make you happy to have me as your son．Yours is the will that gets me through every day．

I don’t believe you can judge a person for the mistakes they make，as we all make them，but you can judge them for what they do afterwards．And after this，when it is all over，you will still have a son with the same hopes and dreams．They have not diminished． If you can dream it，then you have to believe it can happen — right？

So this Mothering Sunday，please think back to that morning in the 80s，the first Mother’s Day without Dad，when a six year old me got up early and made breakfast for you．Do you remember it？Could you ever forget？A slice of bread a doorstep thick and a wedge of cheese equally dense．You didn’t have to eat it，but you did，chewing every dry mouthful．I know now why you forced yourself — because it had been made with love．Well，things don’t change this year — this letter is that bread and cheese (it sure has plenty of the cheese！)．

I love you so much．I am sorry I have let you down，but you have taught me that we will always pick ourselves up and become better than we were before．Thank you for everything and this year，more than ever：

Happy Mothering Sunday．

Love，your son
