This article introduces how to call the fortran code in Python. It mainly uses the f2py program, which is very practical. If you need it, you can refer to calling the fortran code in python, f2py is used. Its project home page is here. Now the project has been merged into numpy. Install python and then install numpy to use f2py. However, for windows, you must use the gnu

Create a Fortran compiling environment in Linux-general Linux technology-Linux programming and kernel information. For more information, see the following. In the past few days, it's okay to get the Fortran in Linux. According to Internet searches, Intel compiler is the most famous and best-to-use. So I searched and downloaded the file online. However, because it was on CERNET, it could not go to Intel's of

written header files or explicitly User-Defined generation rules. for Fortran 90 programming, the concomitant *. MOD files play the role of header files in C/C ++. because they are automatically generated concomitantly with corresponding object files containing implementation of modules, there are no explicit User-Defined generation rules for these *. MOD files. hence, it is useless to put these *. MOD files into the variable built_sources. if no oth

In a KVM virtual machine, how does one perform GPU computing ?, Kvm Virtual Machine gpu computing We know that CUDA is a general parallel computing architecture launched by NVIDIA, which enables complex parallel computing on the GPU. In some scenarios, you must use virtual machines for resource isolation and physical GPUs for large-scale parallel computing. This

Dear heroes, cainiao is here to answer two questions: My cluster is sugon T4000, with 8 nodes in total. Each node has dual CPU and each CUP4 core.

I made a C-to-FORTRAN program a few days ago. I compiled it in windows and ran the result. I didn't expect the result to be wrong in Lunix. After searching for a long time, I thought it was the cause of the global variable. I didn't expect it to be the initial value problem in do while. Integer nNew I didn't set the initial value on wndows, but the operation is correct. I don't know what the initial value is in Lunix. At the same time, the running of

For details about how to debug fortran by GDB and how to print variables-general Linux technology-Linux technology and application information, see the following. After gfortran-g is run, generate the executable file, and then gdb Executable File To print the value of variable Print No symbol "a" in current context prompt One more question: I use two fortran files to generate an executable file. Both

In many C or C + + header file definitions, NULL is specified to be defined as 0, which is no longer specifically expandedGfortran's Manual for the section on ISO c binding, define null as follows Moreover, the following and named constants are defined: Name Type C_NULL_PTR C_PTR C_NULL_FUNPTR C_FUNPTR Both is equivalent to the value in NULL C. Thus, it is ne

Linux programming and kernel information-general Linux technology-about how to configure the fortran environment in Linux. I am a beginner of linux, and I just got started with fortran. I cannot solve any small problem. Thank you for your help. The downloaded intel linux compiler for linux 10 has been installed.

, GPUs is typically used only for graphical rendering (e.g. through Opengl,directx).Developers can do parallel programming by calling Cuda's API to achieve high performance computing. In order to attract more developers, Nvidia has expanded the programming language of Cuda, such as Cuda C/c++,cuda Fortran language. Note Cuda C + + can be seen as a new programming language because Nvidia configures the corresponding compiler NVCC, Cuda

Rewind and BACKSPACE of Fortran languageIn the early Fortran specification and compilers, backspace and rewind were indeed related to sequential storage devices such as tape drives. Later, it becomes a device-independent statement. However, it may be related to file mode.Rewind is still very common now. If your program needs to read the same text format data file two times, when you have finished reading th

I told you how the subroutine can't pass a mutable array.When writing a Fortran program, to achieve a specific function of the matrix, such as the Gauss method to solve the linear equations, many times the subroutine does not know the size of the matrix, such as the finite element program first to use the program to obtain the total stiffness matrix and then gross position just passed in the sub-program to solve the matrix equation. So implementing su

Software developers are often faced with a difficult choice when developing product-level code, you always want your code to be superior, which means you need to compile it at a high level of optimization, and you may want to debug the binary in your product, rather than the source files that are not optimized at compile time. If you've tried debugging optimized code, you probably already know the difficulty: Source code statements do not execute sequentially, or they do not when you want them
