Mentioned:
It is the 17th anniversary of the "Challenger" space plane, and the official circumstance report is that the 0-type seal is invalid, maybe this is the reason why it is more crown and is easy to accept by the government and the public.
But in the Fortran world, such a saying: a DO loop error, burying "challenger".
A simple shallow mistake can not be simple and shallow, the naked eye is easy to find, but in the source code of the Hao Shihai, the naked eye has to be replaced by the compiler, but the compiler cannot find this error:
Do 30 i = 1.1000
......
30 Continue
The above commaings are erroneous writing decimal points, the implicit instructions of the compiler will explain the sentence as:
A real variable DO30i is assigned to 1.1000, not a thousand times! ......
This comma is really expensive, its value is actually a space shuttle and 7 astronauts!
At the time of comrades, you should pay attention.

Mentioned:
Stargazer is worthy of A department, knowing about it is true, and we have to ask for a lot of students in the future.
About HPC).
Stargazer (Wanderer-in-Heavens: Captain St.Argazer) in Sat Mar 8 16:21:11 2003)
Mentioned:
The Colombia wrecked for more than a month, still did not find out the cause,
I don't know if it is the same as the last time, I'm coming down to a part of a part.
Maybe the military secret to cover up is more than the truth of real things!
I hope that it is not an error in a certain Fortran program, that is too embarrassing.
It is seven life and an space shuttle ...
Socialized society today,
Any hardware defect is from manufacturing defects.
The manufacturing defects originated from design defects,
Designed defects originated from the defects of the program,
The defects on the program are inserted, which is the defect of people.
The high performance calculation is even more, and a node is wrong, it will lead to failure of the entire calculation.
The result is the failure of people.
[Mentioned in the masterpiece of Shea (SHEA):】
: Stargazer is worthy of the A department, and it is true that things to their own areas. I have to ask for a lot of students in the future.
