The Work Plan

The original proposal submitted to the dCSE panel requested a combined effort from both NAG and EPCC staff for a full parallelisation of the code with 16 months of effort. The panel approved the proposal but awarded 6 months of effort in order to get a working parallel code. The work plan for the 6 month project is given below in three work package (WP)

WP1

Semi-Parallel Implementation Effort: 3 months

WP1.1

Serial code profiling for two benchmark test cases

• Single non interacting Sphere with 100000 finite element cells
• Non interacting Framboid with 100000 finite element cells

WP1.2

Implement calls to the parallel CVODE solver [1]

• By decomposing the finite elements with a regular ordering
• Study of code performance paying particular attention to load balancing Outputs

D1

WP1 Deliverables

D1.1

Profile of the serial code giving particular attention to detail regarding the performance of CVODE

D1.2

Short technical note to describe the general implementation of CVODE to MicroMag

D1.3

Profile of MicroMag using parallel CVODE

D1.4

Version of MicroMag which uses parallel CVODE

WP2

Fully-Parallel Implementation. Effort: 2 months

WP2.1

Implement calls to the Metis library [2] to give an automated decomposition for a Cubit tetrahedral mesh (as used by MicroMag). This will be done as a preprocessing stage

WP2.2

Implement a local to global mapping for the finite element numbering system within MicroMag which will enable the code to use the decomposition produced in WP2.1

WP2.3

Validate fully-parallel MicroMag with the test cases in WP1.1

D2

WP2 Deliverables

D2.1

Profile of the fully parallel MicroMag code giving particular attention regarding the performance of CVODE

D2.2

Version of MicroMag which uses parallel CVODE and parallel effective field calculations

D2.3

MicroMag code demonstrating parallel scalability up to 256 HECToR processing cores

WP3

Final report and dissemination. Effort: 1 month

WP3.1

Write a technical report detailing work for the project as a whole

D3

WP3 Deliverables

D3.1

Technical report on the work performed during the project

D3.2

A parallel version of the MicroMag code
