3. MAPPER & Multiscale Systems
The world is multiscale
Scale of biomedical applications:
Temporal scale O(1015)
Spatial scale O(109)
Objective of the MAPPER project is to develop computational strategies, software and services for distributed multiscale computing exploiting European e-Infrastructures.
Let‘s start with a simple fact: the world is multiscale. For instance, taking a biomedical application we find ourselves on a temporal scale of 10^15 (molecular events O(10^-6) and human life O^(10^9) seconds) and on a spatial scale of 10^9 (macro molecules O(10^-9) and size of human O(10^0) m).
We want to study an occurrence and development of a phenomena, e.g. an illness, in a human body. So we are bound to work on these scales, however there is no sufficient resources for studying the event at the highest possible resolution. We end up in a situation where microscopic accuracy on a macroscopic problem size results in prohibitive computational and storage demands.
Multiscale models help researchers to study events and simulate systems by taking the best of both worlds. Microscopic detail in the most relevant subsections of the problem and efficiency and problem size advantages of macroscopic simulations.

9. EGI Community Forum, Operations Management Board Meeting
Status quo
e-Infrastructure
Services deployed on multiple resources (local, EGI, PRACE)
Collaboration with European e-Infrastructures
EGI-MAPPER-PRACE task force
Multiscale models and simulations
Two use cases in production
Five use cases under development
Contact with scientific communities
Earth science, Meteorology, Seismology
Status of pilot and production activities:
MAPPER services are deployed on the following resources: Cyfronet, LMU/LRZ, PSNC, SARA, TASK, UCL, WCSS
Mention the current status in the task force; interest of the UK communities.
Production use cases include in-stent restenosis and nanomaterials
We are in contact with several communities not represented in the project, including meteorology (DRIHM), earth science (NGI_UK) and seismology (VERCE), identifying capabilities for supporting their research.
Remember that these efforts are community driven. Extending capabilities of e-Infrastructures to provide state of the art services satisfying requests of the European scientific communities
MAPPER goal is to develop and support novel computational methodologies by providing scientific community with services and tools for multiscale computing.
