I am attempting to compile and run a Fortran 90 program using command line (bash). In the past, when I've run gfortran /path/to/file, a file a.out and a file program_name are created, and I can run ...

I'm one of the developers of the Lumen code: https://www.lumen-code.org/. That is computational code for condensed matter physics simulations. We are replacing FORALL with DO CONCURRENT, since FORALL ...

We have a small local compute cluster consisting of 5 compute nodes (all supposedly having the same hardware and software) and a login/storage node. I'm running an in-house Fortran software that uses ...

Assume that I read an array of char from any source and I want to convert it into an array of int8. What is the best way to do it. Here I have two propositions, but may be there is another more suited ...

Could you tell me how to write type-bound procedures for parameterized types? For example: module parameters type :: sinx (kind) integer, kind :: kind=4 real(kind) :: x contains procedure,...

I am trying to use FFTw3 in Visual Studio using the Intel Fortran compiler. I am confused about normalization. I have setup a r2r spectral to grid plan for sinx siny components. ...

I have a fortran dll/so which needs to know its own programhandle. On windows, I can obtain the handle from the DLLMain routine: integer(4) function DllMain(hInst, ul_reason_being_called, lpReserved) ...

I am optimising a code already parallelised but not very optimised because of the very different duration of operations among the threads, even though all threads have a similar task to do. So I ...

I'm working on porting the CAMB (Cosmological Boltzmann code) to run with hybrid CPU+GPU parallelization using OpenMP and OpenACC with NVIDIA HPC SDK compilers. The code works perfectly when compiled ...

The TLDR: I have a Fortran function, shiftxe_pos that acts on an element fe(i,j,:,:) with integer, parameter :: dp = kind(1.0d0) integer, parameter :: nx integer, parameter :: nv ...

I have a toy project about designing a very simplified exception system in Fortran that imitates Python's exceptions. Until now, it appears to work, but I stumbled upon an inconvenience. I must say ...
