Excelsior JET Embedded Improves Lagoni Engineering's Wind Turbine Analysis Over Greenland Winter
NOVOSIBIRSK, Russia, Mar. 28, 2012 -- The Institute for Arctic Technology at the Technical University of Denmark (DTU) recently worked on a project in Greenland intended to determine the impact of combining renewable wind energy with existing diesel generators in small villages with independent electrical grids. There was just one problem: DTU researchers back in Denmark needed a reliable, affordable way to analyze the data both historically and in real-time. For that solution they turned to Lagoni Engineering Ltd. -- and Lagoni turned to Excelsior LLC and its Excelsior JET Embedded (http://www.ExcelsiorJET.com/Embedded/).
Arctic conditions ruled out upgrading hardware, causing Lagoni to find performance improvements within the existing platform. "We were looking for a way to reduce the hardware requirements and cost associated with conventional Java, which powers Monatar, our in-house datalogger with a built-in Web server that provides the user interface for the researchers," explained Thomas Olsen, director of Lagoni Engineering Ltd. "We found what we needed in Excelsior JET Embedded."
Monatar is a high-performance embedded energy-monitoring device for wind turbine analysis, and it is critical to the DTU researchers' mission. Excelsior JET, a certified Java SE Embedded runtime (JVM) and an ahead-of-time (AOT) compiler, powered -- and boosted the performance of -- Monatar in the bitter cold of a Greenland winter.
In fact, Excelsior JET Embedded delivered a 45% improvement on Oracle's JVM start-up, between 15% and 30% improvement on JVM response, and a full 60% improvement on JVM's disk footprint size. What's more, said Olsen, Excelsior JET Embedded "made the final deployed Monatar application virtually impossible to reverse engineer," which gave Olsen's team peace of mind.
Because of the remote location and unstable satellite connection, simple software upgrades were crucial. Excelsior JET Embedded fit the bill there, too: A typical Excelsior update involves transferring a single file, rather than the multiple files required for other Java native compilers.
