Miracle Consortium: Progress Report Nick Achilleos (UCL), Consortium Chair, Miracle Co-I; Jeremy Yates (UCL), Miracle Co-I Brief report prepared according to outline suggested by STFC Consortium infrastructure for HPC Consortium science 

Objectives and Vision  The ‘Miracle’ family of projects are aimed at making use of HPC for the purposes of modelling and characterising astrophysical environments from atomic through cosmological scales. This aim naturally provides research links between Miracle teams who work on different aspects of a problem.

Miracle Consortium’s Contribution to Facility UCL have given ~200K of support to MC for both science and ops: -Part support for Miracle Support Programmer from Jan 2010 (~2.5 yr total support UCL+STFC). -Support for Miracle Research Computing Consultant from Jan (1.5 yr) -Support for Leverhulme Research Fellow in Planetary Science from Jan (2 x 0.5 yr) 

The Miracle Support Programmer, Dr. Dugan Witherick, has academic, management and user- facing experience. He will provide: Assistance with software / hardware issues for key projects. Advice to users on: optimum usage of the various Miracle facilities for computing / storage, and Grid Computing. Infrastructure to promote collaborations, e.g. web deployment of applications, Wiki pages, file shares. Hardware procurement advice. Assistance with delivering educational seminars with Miracle Consultant.  Miracle Consortium’s Contribution to Facility

The Miracle Consultant, Dr. Patrick Guio, has both academic and industrial experience. He will provide: Assistance for the Miracle Support Programmer with migration and maintenance of codes. Consultation to users on software design and algorithm implementation (important for research). Assistance with delivering educational seminars on issues such as: good design / programming practice, maintenance and migration of code, computational algorithms. Miracle Consortium’s Contribution to Facility 

The Leverhulme Fellow, Dr. Caitriona Jackman, has also acquired 1 extra year of RAS support. Her work is high-profile (linked to Cassini Mission at Saturn) and she will develop new data mining techniques within UCL Planetary Physics Laboratory, using the HPC facility. Miracle Consortium’s Contribution to Facility 

Growing interdisciplinary links:  Growing links between disciplines: Achilleos et al, MNRAS, 2010: ‘A model of force balance in Saturn’s magnetodisc’ - Invitation to give seminar Oct 2010 at Dept of Applied Mathematics, Univ of St Andrew’s

Summary  The Miracle - UCL RC relationship has been successful in establishing the Legion production facility, accessible to Miracle users since Feb Local development capability enhanced through procurement of SMP machines. Support from UCL recognizes that hardware must be complemented by science and skills transfer - support for Miracle programmer, Miracle Consultant, Leverhulme Fellow. Miracle Consortium will work with STFC, other consortia to ensure ongoing progress is reported and monitored.
