Nmag console commands in a nutshell

Nmag is a python-based micromagnetic simulator for finite elements mesh. First we add the path and one alias for a comfort work to our bashrc from <nsim>/bin directory: echo "export PATH=\$PATH:`pwd`" >> ~/.bashrc echo "alias nmeshimportg='`pwd`/nmesimport –gmsh'" >> ~/.bashrc Convert the mesh in Version ASCII v2.x format to Version 1:…

Some tips for MPI and cluster usage

Note, that all information below may not be suitable for every computing cluster due to many differences in operation systems and local settings for user management and parallelization software. Available modules. Command $ module avail gives the list of available modules, such as mpi/openmpi/1.3.2/intel for example. Command «module load <modulename>», where <modulename>…

Multithreading OOMMF in Linux

Today I want to say some few words about the multithreading OOMMF in Linux. As I know in Windows the last versions of OOMMF, like 12a4 and later (OOMMF), are basically could keep more than 1 thread and accelerate the simulations by paralleling calculations, but you may use for this multithreading Tcl/Tk.  In the…

Fun with very large numbers from R. Baillie

I have found a link to an interesting paper in a one social network. Robert Baille shows a few tricks with «almost» true functions: they can be true in the huge interval of their arguments, but fail for the other their values. And numerical methods will fail for direct check. Link…
