Mesabi Dedication and 2015 Research Exhibition

On Thursday, April 23, MSI held the sixth annual MSI Research Exhibition and dedicated our newest supercomputer, Mesabi. Mesabi is an HP distributed cluster featuring a large number of nodes with leading-edge Intel processors that are tightly integrated via a very high speed communication network. In addition, it contains a significant number of nodes with very large memory (up to 1 TB per node), accelerator nodes (GPU), and nodes with solid-state storage devices (SSD) for ultra high performance input/output.

At the Research Exhibition, MSI researchers presented posters of their work using MSI. The posters were judged by a panel of faculty members and prizes (travel awards) will be awarded. Posters competed in one of two categories, Physical Sciences and Engineering or Biological and Medical Sciences. Entrants were from a wide variety of disciplines. Ninety posters were submitted for the Research Exhibition, 81 of which participated in the competition. See photos from the event.

The judges awarded a Grand Prize winner in each category. The authors received a $1,500 travel award that can be used for conferences or professional meetings. 

Biological and Medical Sciences Grand Prize: NINJA is not just another - short-reader mapper; authors: Gabriel Al-Ghalith, Emmanuel Montassier, Dan Knights; MSI PI: Dan Knights (Computer Science and Engineering)

Physical Sciences and Engineering Grand Prize: Equilibrium properties of DNA confined in nanochannels: A Monte Carlo chain growth approach; authors: Abhiram Muralidhar, Kevin D. Dorfman; MSI PI: Kevin D. Dorfman (Chemical Engineering and Materials Science)

Each category also had two Finalist prizes, who received $1,000 travel awards:

Biological and Medical Sciences Finalists:
Conformational dynamics of TNF receptors revealed by enhanced sampling techniques in molecular dynamics and free energy calculations; authors: Andrew K. Lewis, Anthony R. Braun, Christopher C. Valley, Jonathan N. Sachs; MSI PI: Jonathan N. Sachs (Biomedical Engineering)

Identification of novel candidate biomarkers and therapeutic targets in human sarcomas by systematic RNA sequencing; authors: Anne E. Sarver, Aaron L. Sarver, Venugopal Thayanithy, Subbaya Subramanian; MSI PI: Subbaya Subramanian (Surgery)

Physical Sciences and Engineering Finalists:

First-principles insights on line defect in strained NdTiO3 on SrTiO3; authors: Mehmet Topsakal, Jong Seok Jeong, Peng Xu, Bharat Jalan, K. Andre Mkhoyan, Renata M. Wentzcovitch; MSI PI: Renata M. Wentzcovitch (Chemical Engineering and Materials Science; MSI Fellow)

Research Exhibition attendees also voted on a People's Choice award. The poster receiving this award was Multiscale model of strain-dependent glomerular basement membrane remodeling; authors: Sarah Vanderheiden, Mohammad F. Hadi, Victor Barocas; MSI PI: Victor Barocas (Biomedical Engineering; MSI Fellow). These authors received MSI t-shirts.

Right: A half-elipsoid mesh was used to model the isolated Pacinian corpuscle (PC). The ellipsoid had a major axis of length 1 mm and a minor axis of length 500 μ-m. Delaunay networks were rotated to become circumferentially aligned within the PC. 10 μm indentation of a cylindrical rod of diameter 250 μm occurred along the +z axis.
