cuda fortran

Python calls the fortran module and pythonfortran module. The f2py program is used to call the fortran code in python. 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 fortran compiler gfortran, Which is downloaded here. After installing python,

As the first advanced language, Fortran still plays an irreplaceable role in scientific computing. Recently, I tried to use Math.net to perform matrix operations in C #. Although operators are overloaded and supported by the corresponding mathematical libraries, I feel that the convenience of matrix operations is lacking compared with Fortran. In addition, compared with C/C ++,

CUDA and cuda ProgrammingCUDA SHARED MEMORY Shared memory has some introductions in previous blog posts. This section focuses on its content. In the global Memory section, Data Alignment and continuity are important topics. When L1 is used, alignment can be ignored, but non-sequential Memory acquisition can still reduce performance. Dependent on the nature of algorithms, in some cases, non-continuous access

The method should be the same. I use the green version of ultraedit 16.00.0.1032 and Windows 7. Open the directory where ultraedit is located and create a new file under wordfiles.

Recently toss the Fortran code, and most of it is F77, it is the brain vertigo. The relationship between the formal parameters and the actual parameters of functions in C naturally is clear in the chest, to the Fortran some confusing mind. In fact, the subroutine in the Fortran parameter passing similar to Python, finally found a little familiar with the shadow

For a long time, the Fortran compiler in GCC only complies with the Fortran 77 standard. In today's opinion, this language is very primitive. If you want to write a do until loop, you have to write it like this: 10 continue Mywork If (condition) goto 10 Worse, f77 has no ADT capability, which makes it impossible for many software design methods developed in 1980s to be applied in

compiler and language improvements for CUDA9 Increased support for C + + 14 with the Cuda 9,NVCC compiler, including new features A generic lambda expression that uses the Auto keyword instead of the parameter type; Auto lambda = [] (auto A,auto b) {return a * b;}; The return type of the feature is deducted (using the Auto keyword as the return type, as shown in the previous example) The CONSTEXPR function can contain fewer restrictions, including var

Summary of accelerated installation of Amber11 + AmberTools1.5 + CUDA The following installation method is based on some of the previous posts on the Forum simulated by the numerator. The installation and testing can be successful as long as the operation is correct. Considering that Amber11 is generally installed on clusters, the intel compiler and Openmpi parallel tool are used for installation. You need to purchase the Amber11 software to obtain th

1. vasp4.6 is a commercial software for Quantum Chemistry computing. Here is the source code package. From Austria. This software can also be used in physics for molecular dynamics analysis. 2. Declare that vasp4.6 cannot be compiled on the intel Fortran compiler 8 series. A fortcom internal error is reported. This is a compiler bug. 3. We recommend that you compile VASP on Intel Fortran compiler V7.

Next, we'll continue here to introduce Python's example of passing a two-dimensional array to Fortran and returning it with a simple calculation.Problem Description:Python NumPy defines a two-dimensional array that is passed to the FORTRAN program after the calculation is returnedRestrictions: In Python, you must determine the size and dimension of the array The array stored in Python, defined

One, using the GPU module provided in the OPENCV At present, many GPU functions have been provided in OpenCV, and the GPU modules provided by OPENCV can be used to accelerate most image processing. Basic use method, please refer to: http://www.cnblogs.com/dwdxdy/p/3244508.html The advantage of this method is simple, using Gpumat to manage the data transfer between CPU and GPU, and does not need to pay attention to the setting of kernel function call parameter, only need to pay attention to the l

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

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.
