febioThe Scientific Computing and Imaging Institute and the Musculoskeletal Research Laboratories are proud to announce the 1.0 release of the software FEBio, "Finite Elements for Biomechanics". FEBio is a nonlinear finite element software package that is specifically designed to address problems in computational biomechanics. Some of the features of note include capabilities for contact, rigid bodies and kinematic joints, nonlinear anisotropic constitutive models, simulation of active contraction, poroelasticity, element formulations for nearly-incompressible materials and parallel solution of the linear system of equations. After extensive testing in our lab and with our collaborators, we are happy to offer this free software to the research community. FEBio is currently available for WindowsXP, MacOS/X, Suse Linux (64 bit Opteron/Athlon64) and SGI Altix (64 bit Itanium2). We would be happy to port FEBio to other Unix/Linux platforms. The FEBio distribution includes the User's Manual, Theory Manual and several test problems to verify proper operation.

Dr. Claudio Silvaclaudio has been honored once again with a coveted IBM Faculty Award. This award is designed to promote innovative, collaborative research and honor outstanding faculty working in disciplines of interest to IBM. It includes $30,000 to support ongoing research. Dr. Silva is being recognized for his continuing success in developing efficient rendering techniques for large-scale scientific visualization. The increase in computational power has enabled the generation of large and complex simulations. Scientists and engineers are now faced with an incredible amount of data to analyze. Despite considerable effort, techniques for the visualization of large datasets, common in scientific simulations, still take too long. In addition, most current techniques suffer from strict data size limitations due to the reliance on having the complete datasets in main memory. In order to address the interactivity and scalability requirements, the Dr. Silva and his team are developing novel out-of-core, streaming, and parallel algorithms for optimizing the visualization of large datasets. The development of scalable rendering algorithms is of key importance to the advancement of visualization, graphics, and computational science.
mozyAndrew Kensler took the $10,000 grand prize in Mozy.com's Coding Deathmatch. The contest consisted of three timed rounds of competition, two preliminary rounds were held online and the final round at Mozy.com's American Fork (Utah) headquarters. Only the top eight contestants were allowed to proceed to the final round. Contestants were asked to write programs in any of nine possible languages to to solve a series of problems. The winning code was graded on it's ability to solve the problem in the least amount of execution time. The problem for the final round was to write a program that would read through a 2GB file of 20 million records of 100 bytes each. The first 8 bytes represented the key for that record and the remainder was a payload. The program had to write out a file containing just the records that would be in the 0, 1M, 2M, 3M... positions as sorted by the key values. Ties between keys were to be broken by original order in the file. Wall-clock execution time of the correct programs was used to decide the final ranking for the contest. Timings were done on a virtual machine with 1GB of RAM and 4GB of scratch disk space available.

map3d-6-5The Scientific Computing and Imaging Institute and the Center for Integrative Biomedical Computing are proud to announce the release of map3d version 6.5!

This release includes a number of fixes and additions to the display settings for map3d and major new support for displaying time fiducials. The driving application for this was displaying maps of activation, recovery, start of QRS, etc., both as separate isochronal maps and superimposed on the scalar time series data. If you need this, you will love map3d's new capabilities.

The Scientific Computing and Imaging (SCI) Institute and the Center for Integrative Biomedical Computing (CIBC) are proud to announce the first major release under the new center of their flagship software SCIRun/BioPSE Version 3.0!

The Biomedical Problem Solving Environment, or BioPSE, contains a suite of applications and integrated problem solving systems that have been specialized to meet the needs of scientists working in major fields of biomedicine. In order to design the best systems to meet real world needs, the CIBC has established collaborations with prominent scientists who are leaders in their fields. The goal of these collaborations is to develop software that is well suited to the needs of scientists working in these and related fields of biomedicine.

mozy-deathmatchCompeting individually in the Mozy Code Deathmatch, SCI developers McKay Davis, Michael Callahan and Bryan Worthen represented three of the eight finalists and shared in the grand prize of $10,000. This unique coding contest was conducted with two online preliminary rounds and a final round held at Mozy.com's American Fork (Utah) office. The first round, lasting just an hour, required contestants to solve six small programming puzzles. The second round challenged the remaining contestants with four more difficult problems. The eight finalists then were invited to Mozy.com's office to compete head-to-head. In the final round, the contestants were asked to write - in under ninety minutes - a small web server capable of handling 10,000 simultaneous connections. To assess the contestants' efforts, the judges then used a test client to connect and to establish a data connection with each server 10,000 times in a short period. Each server then had to sort the data and retrieve three specific pieces of the data. Although all finalists managed to develop a functioning server, none of their servers scaled well enough to meet the full scope of the challenge. After some debate, all agreed to declare the competition a tie and to split the prize money equally among the finalists.
