David R. Greenebaum David Greenebaum leads the development and implementation of managed services and products, providing customers with the framework to modernize and integrate their complex applications onto new computing architectures. Mr. Greenebaum’s recent efforts have focused on high performance computing where he is responsible for the development of grid and cluster solutions that meet the challenging requirements of large compute bound problems. The types of problems that fit this paradigm are: computational fluid dynamics, molecular modeling and seismic analysis. This work includes the efforts to migrate applications from large, monolithic systems to heterogeneous networks of computers interconnected with MPI (Message Passing Interface). He has also helped customers to replace their existing failing architectures with a reliable core infrastructure while assuring full interface to legacy systems. Greenebaum’s broad-based experience in computing and communications infrastructure, spanning more than 25 years and a range of industries, enable him to address complex technological developments in an accessible way. Understandable to a broad audience, his efforts are often noted for combining solid engineering expertise with a profound understanding of business models. While Greenebaum lead many initiatives, he has recently focused on the creation of a large computing cluster (over 3000 processors), web services products and on the implementation of Services Oriented Architectures. Other recent efforts have included high performance transport layers, which addresses the implementation and optimization of sophisticated grid and cluster applications, and future network trends, which tackle upcoming network technologies and their impact on e-commerce. Mr. Greenebaum has presented papers at industry and GSA forums on a range of topics including: performance tuning database applications, network architecture, web services and high performance computing.   Contact Us Home
