In Linux, we can use commercial compilers or free compilers. GCC, g ++, and FORTRAN (g77) Compilers are included in most Linux distributions. Among them, the C and C ++ compilers are already very good, and the FORTRAN compilers are constantly improving. Commercial

also help improve performance. In addition, Modularity also will be independent of the work of each phase of the compiler as far as possible. For example, the compiler can perform specific CPU-independent optimizations, or specific optimizations for a particular CPU, which can be done independently without having to redesign the entire system.It may be surprising that the various stages and modules of the compiler are designed and even related to the syntax of this programming language. For exa
applications that require very low latency, it is worthwhile to use a lower-level and low-productivity language, C ++, to maximize performance. For highly concurrent and multi-threaded applications, Python is not an ideal programming language, because Python has something called GIL (Global interpreter lock, this is a mechanism to prevent the interpreter from executing multiple Python bytecode commands at the same time. This does not mean that Python cannot execute real multi-threaded parallel

This article is an interview with Joshua Bloch, Chief Java architect of Google, by Peter Seibel, expert of commmon lisp, talking about what books programmers should read, how they can quickly get familiar with a new language, and why they choose programming languages is like choosing a bar.
Seibel: How did you start programming?
Bloch: I think this is because of my family influence. My father is a chemist at the Brookhaven National Laboratory. When I
value of the function, as shown in figureIf the return value of the function is void, it is not displayed.
Another similar command can also complete this function-print, print can be followed by expressions, soYou can use it to call the function. The difference between print and call is that if the function returns void, the call is not displayed.Print: the return value of the function is displayed, and the value is stored in historical data.

Readers may be familiar with the basic concepts of programming and programming languages. The following describes some terms used in this book in a general sense and describes the relationship between C ++ and other programming languages.
No matter which programming language is used, the program written is composed of various commands. These commands are called source code and stored in the disk's source file. At present, there are many programming languages, each of which has its own advantages

Cluster Management
System management and maintenance is a very tedious task, especially for large clusters. However, we can find some tools and scripts on the Internet to simplify the work. For example, a node must be in time and system files (/etc/passwd,/etc/group,/etc/hosts,/etc/hosts. equiv and so on), so a simple script that can be scheduled by cron can be used to complete the synchronization process.

Blitz ++ is an efficient function library for numerical computing. It is designed to create a set of computing environments that are as convenient as C ++ and faster than FORTRAN. Generally, the numerical program written in C ++ is about 20% slower than that written in FORTRAN. Therefore, blitz ++ just wants to

However, it should be noted that the two parameters of main do not have one-to-one correspondence with those in the command line. Because there are only two main parameters, and the number of parameters in the command line
