A brief history of Fortran




Fortran is one of the oldest and most widely used programming languages in the world. It was developed in the 1950s by John Backus and his team at IBM as a high-level language for scientific and engineering computations. The name "Fortran" stands for "Formula Translation", as it was designed to translate mathematical formulas into machine code. The first version of Fortran, known as Fortran I, was released in 1957 and was followed by several revisions and enhancements, such as Fortran II, Fortran IV, Fortran 66, Fortran 77, etc.


In 1991, a new standard for Fortran was published, known as Fortran 90. It introduced many new features and improvements to the language, such as free-form source code, modules, derived types, dynamic memory allocation, array operations, pointers, recursion, generics, operator overloading, etc. It also deprecated some obsolete and redundant features of the previous versions of Fortran. Fortran 90 was a major milestone in the evolution of the language and paved the way for further developments and innovations.


Since then, several new standards and extensions for Fortran have been developed and adopted by the Fortran community, such as Fortran 95, Fortran 2003, Fortran 2008, OpenMP*, Coarray Fortran*, etc. These standards and extensions have added more functionality and flexibility to the language, such as object-oriented programming, parallel programming, interoperability with C, enhanced input/output, etc. Today, Fortran is still a popular and powerful language for scientific and engineering applications that require high performance and accuracy.

How to optimize your Fortran code with Developer Studio Fortran 90




One of the main goals of using Developer Studio Fortran 90 is to optimize your Fortran code and make it run faster and more efficiently. Developer Studio Fortran 90 provides various tools and options that can help you achieve this goal, such as:


The compiler options and settings




The compiler options and settings are the parameters that control how the compiler generates the executable code from your source code. You can customize these parameters to suit your needs and preferences, such as choosing the optimization level, enabling or disabling certain features, specifying the target architecture, etc. You can access and modify these parameters using the Project Properties dialog box or the Option Manager window. Some of the most important compiler options and settings that affect the optimization of your code are:



  • The optimization level: This is a general parameter that determines how much the compiler tries to optimize your code. You can choose between different levels, such as no optimization, basic optimization, advanced optimization, etc. The higher the level, the more aggressive the compiler is in applying various optimization techniques, such as loop transformation, vectorization, parallelization, interprocedural optimization, etc. However, higher levels may also increase the compilation time and the code size.



  • The vectorization: This is a specific parameter that determines whether the compiler tries to use vector instructions to speed up your code. Vector instructions are special instructions that can operate on multiple data elements at once, such as adding two arrays element-wise. You can enable or disable vectorization for your whole project or for specific loops or routines. You can also specify various options to control how the compiler performs vectorization, such as choosing the vector length, aligning the data, handling dependencies, etc.



  • The parallelization: This is another specific parameter that determines whether the compiler tries to use parallel threads to speed up your code. Parallel threads are multiple execution units that can run simultaneously on different cores or processors, such as dividing a loop among four cores. You can enable or disable parallelization for your whole project or for specific loops or routines. You can also specify various options to control how the compiler performs parallelization, such as choosing the number of threads, setting the affinity, handling synchronization, etc.



  • The interprocedural optimization: This is another specific parameter that determines whether the compiler tries to optimize your code across different procedures or modules. Interprocedural optimization can improve the performance of your code by eliminating redundant or unnecessary operations, inlining functions, propagating constants, etc. You can enable or disable interprocedural optimization for your whole project or for specific procedures or modules. You can also specify various options to control how the compiler performs interprocedural optimization, such as choosing the scope, setting the threshold, handling recursion, etc.



  • The profile-guided optimization: This is a special parameter that determines whether the compiler tries to optimize your code based on the actual behavior and characteristics of your code execution. Profile-guided optimization can improve the performance of your code by adjusting various parameters and options according to the collected profile data, such as choosing the best optimization level, selecting the best vectorization or parallelization strategy, reordering or rearranging the code, etc. You can enable or disable profile-guided optimization for your whole project or for specific procedures or modules. You can also specify various options to control how the compiler performs profile-guided optimization, such as choosing the profile mode, setting the sampling rate, handling feedback, etc.



These are some of the most important compiler options and settings that affect the optimization of your code. You can find more detailed and specific information and instructions in the user guide and the online help of Developer Studio Fortran 90.


The debugging and profiling tools




The debugging and profiling tools are the tools that help you find and fix errors in your code and measure and improve the performance of your code. Developer Studio Fortran 90 provides various debugging and profiling tools that can help you achieve these goals, such as:



  • The graphical debugger: This is a tool that helps you find and fix errors in your code by allowing you to control and monitor the execution of your code. You can set breakpoints, watch variables, inspect expressions, modify values, step through your code, etc., using a graphical debugger window that shows you the source code, the call stack, the registers, the memory, etc. You can also use various commands and options to control the execution and behavior of your debugger.



  • The graphical profiler: This is a tool that helps you measure and improve the performance of your code by allowing you to collect and analyze various metrics and statistics about your code execution. You can collect and analyze various metrics and statistics about your code execution, such as CPU time, memory usage, cache misses, branch mispredictions, etc., using a graphical profiler window that shows you the source code, the call graph, the hotspots, etc. You can also use various filters and options to focus on the relevant parts of your code.



  • The code analysis tool: This is a tool that helps you check the quality and correctness of your code by allowing you to detect and diagnose various errors and warnings in your code. You can detect and diagnose various errors and warnings in your code, such as syntax errors, semantic errors, memory leaks, uninitialized variables, array bounds violations, etc., using a graphical code analysis window that shows you the source code, the messages, the locations, etc. You can also use various options and settings to customize the level and scope of your code analysis.



  • The performance tuning tool: This is a tool that helps you identify and eliminate bottlenecks in your code by allowing you to perform various experiments and tests on your code.
