Computationally intensive Research in the MGHPCC Consortium
High-performance computing (HPC) systems that bring together large numbers of CPUs and massive amounts of storage, are playing a transformative role in research. For example, high performance computers are used to create, simulate and solve models of complex phenomena that range from protein structure, to turbulent fluid flows, to the dynamics of the earth’s atmosphere, to pathways of human social interaction, to galactic evolution. These models provide new perspectives and new ways of making discoveries. The following is a small sample of the computationally-intensive research being conducted at the MGHPCC universities.

Science and Policy of Global Change.
Understanding the complex, long-term changes in our land, air and water requires breakthroughs in measurement, modeling and prediction.

The Joint Program on the Science and Policy of Global Change is MIT’s response to these research, analysis, and public education challenges. At the heart of much of the Program’s work lies MIT’s Integrated Global System Model (IGSM), a linked set of computer models designed to simulate the global environmental changes that arise as a result of human causes. In this way, it explores the interplay between Earth systems and human activity. MORE

They have been an object of fascination for astronomers and astrophysicists for many centuries. Fisher models their behavior using large computer simulations which simultaneously solve the complex physics equations that make up a detailed theoretical description of a star or star pair. MORE
Exploring the Dark Matter Substructure of Milky Way Galaxies.
Anna Frebel (MIT), Edmund Bertschinger (MIT), and Lars Hernquist (Harvard) are using astronomical observations and the fundamental laws of physics to improve our understanding of how galaxies assemble, their origins, and what controls their characteristics. With the advent of computers, astrophysicists have been able to build increasingly sophisticated models of the growth of agglomerations such as the Milky Way through so-called N-body simulations. In this project, the investigators seek to leverage High Performance Computing to allow them to run not one but multiple N-body problems in parallel, enabling them to apply statistical approaches to uncovering the underlying physical processes at work. It is hoped this will lead to the conclusive confirmation of the details of the assembly history of the Milky Way as well as a better understanding of general galaxy behavior.

Organic Light Harvesting Antennas.
Typically plants need an average of at least a few hundred watts per square meter of solar radiation to survive. At depths of a few hundred meters down in the ocean, the amount of solar radiation decays to around a millionth of the surface intensity so that photosynthesizing organisms at such depths only receive 10-4 Wm-2 of radiation. MGHPCC seed fund awardees Alán Aspuru-Guzik (Quantum Chemistry, Harvard) and Alfredo Alexander-Katz (Materials Science, MIT) are studying the properties of a photosynthetic bacteria (Chlorobium Tepidum, also known as Green sulphur bacteria) that manages to survive in this low energy environment. Their work seeks to understand the interplay between biomolecular structure and efficient light harvesting on the quantum scale and how this could lead to radical new approaches to energy generation.

Computational Identification of Outcome-Associated DNA Alterations in Neuroblastoma
Stefano Monti (BU) and Roberto Chiarlie (Harvard) are investigating ways to improve the effectiveness of treatments for Neuroblastoma, one of the most common tumor-causing cancers in children. Clinically, neuroblastoma is classified in 4 stages, with increasingly poor prognosis. However a significant subset of stage 4 patients (the most advanced stage) can be cured and may even regress spontaneously. The goal of this study is to develop high-throughput sequencing techniques to identify novel DNA markers allowing the two prognostic groups to be distinguished, informing subsequent treatment decisions.
Genome-scale Characterization of Chromosonal Aberrations Using Parallelizable Compression Algorithms.
Dan Simovici (UMass Boston), Nurit Haspel (UMass Boston), David Weisman (UMass Boston), and Jennifer Rosen (BU) are seeking to speed up detection of genetic mutations that cause cancer. One of the great difficulties in developing effective cancer treatments is the stochastic or statistically varying nature of these mutations – each patient and each tumor may present a unique genomic signature. As individual full-genome sequencing comes within reach, this research will develop new data compression techniques (essentially automatically locating and leveraging repetitive sequences) for large-scale data mining of next-generation DNA sequencing data to speed-up detection of large chromosomal aberrations.
Automated Segmentation of Vessel Network Structures in Large Image Stack Sets.
Deniz Erdogmus (Northeastern) Jeff Lichtman (Harvard) and David Boas (Harvard/Mass. General Hospital) are developing software that will improve our understanding of the complex behavior of neuronal circuits, and how they evolve during synaptic competition. Today neuroscientists must manually construct the tree-structured nerves from 3D microscopy imagery. Manual reconstruction of a single cell may take weeks to months depending on its type and complexity. In this project, the team seeks to develop an open high-performance automatic image analysis software package to massively accelerate this process, making it feasible to analyze automatically or interactively a large imagery database for quantitative modeling and statistical analysis.
