How do I get Visual Studio 2019 configured with Intel Fortran 2023 to link the MKL linrary code into an EXE that is generated by building a Fortran project? A few MKL routines have been used in this project. The…
I have a parallel code with OpenMP which is a mix of Fortran, C and R. The Fortran and C are the back-end or solver of the code (it's a computational code) and the R part is just an interface…
In a parallel loop, I process a shared array using a subroutine to which I pass the array and the current private-do index as parameters, but the program crashes with an array out-of-bounds error. How to correctly call a subroutine…
I am trying to compile a Fortran code on a Linux Ubuntu machine and I'm getting the following error (in bold): calcul@gpuserver:~/dp3D/src$ ./makedp3D Do you want to use standard directory /home/calcul/bin/dp3D/ (y/n) ?y Using existing directory: /home/calcul/bin/dp3D/ objects will be…
I am working with an older Fortran code and during compilation I get many different error messages, some of the of the following format: if(iand(n_jz2_max,1).eq.0) then 1 Error: Arguments of ‘iand’ have different kind type parameters at (1) where n_jz2_max…
ifort version: (IFORT) 2021.8.0 20221119 OS: WSL Ubuntu 20.04LTS I have a (1000x1000x1000) 3D array to distribute among procs. In the first approach, I flatten the array and then distribute arrays among procs and it takes about 7.86sec In the…
I am coding and running a physics simulation in Fortran using MS Visual Studio Code on Windows 11 and I want to use MPI. I have installed Microsoft MPI (MSMPI) and know that it is correctly installed. When I enter…
I wrote a program in Fortran that uses RANDOM_NUMBER() and was compiled with gfortran, but I noticed that the generated random numbers are inconsistent between versions. If RANDOM_SEED() is not used to seed the random number generator, then both, gfortran…
I have a subroutine ran_init ( length ), in which one IF statement works incorrectly. The code below is a highly simplified version of my original code: MODULE ran_state USE nrtype IMPLICIT NONE INTEGER, PARAMETER :: K4B = SELECTED_INT_KIND (…
I would like to produce the same random number sequence in both a program written in C and Fortran. I am using gcc version 10.3.0 within Windows Subsystem for Linux (Win10) running Ubuntu 20.04 LTS. I've tried using the same…
