Distributed Computing Resources

MX200 Computing Cluster

This cluster is managed by the Materials Science and Engineering department here at the University of Sheffield.

MX2012 Computing Cluster

This cluster is managed by the Materials Science and Engineering department here at the University of Sheffield.

Iceberg High Performance Computing Cluster

This is a university-wide cluster and is managed by CiCS on behalf of the University of Sheffield. For more information visit: http://shef.ac.uk/wrgrid/iceberg

Micromagnetic Modelling Software

OOMMF

OOMMF (Object-Oriented Micromagnetic Framework) is a CPU-based, open source, finite difference micromagnetic solver. In our group OOMMF is typically used to simulate magnetic domain wall propagation along permalloy nanowires. Jobs are typically run overnight on desktop workstations, however, larger jobs are usually run on one of the MX computing clusters. For more information visit: http://math.nist.gov/oommf

FEMME

FEMME (Finite Element MicroMagnEtics) is a CPU-based, proprietary, finite element micromagnetic solver. FEMME is typically used for simulating fully three-dimensional structures that involve complex geometries and multiple materials such as in granular media or micromagnetic devices. FEMME jobs are exclusively executed on our MX computing clusters. For more information visit: http://suessco.com/en/simulations/solutions/femme-software

mumax3

mumax3 is a GPU-based, open source, finite difference micromagnetic solver and was first used in our group in early 2014. We currently run mumax jobs on two dedicated PCs, with each PC containing two GPUs for a simulation potential of four concurrent jobs. On the right hardware mumax typically executes ~10-20x faster than competing CPU-based simulation software such as OOMMF. For more information visit: http://mumax.github.io

Vampire

Vampire is an open-source CPU-based, atomistic simulation package. Developed at York University, it offers the ability to model complex systems at a natural atomic scale, it can be used to model granular systems, heat-assisted recording and more.  Vampire offers a number of methods to solve simulations, similar to micromagnetic solvers orMonte Carlo methods,  with the options of output 3D visuals or data logs. Jobs can be run on a workstation, or on the MX cluster. For more information please visit: http://vampire.york.ac.uk
