Helios
Sunflow Distributed Rendering
Helios:
Helios enables the distributed rendering of 3D models building on open source technologies that are all 100% pure Java. The rendering engine is Sunflow with the distributed computations managed by the JGrid service-oriented Grid system that uses the Jini technology as its base.- Measurements were done using 17 PCs with identical hardware setup and connected with 100Mbit/s Ethernet.
- MFlops values were computed using the Java version of SciMar2 benchmark with the option “large”
- Wikipedia definitions of speedup and efficiency can be found here.
