Establishing meaningful relationships between cellular structure and function requires accurate morphological reconstructions. In particular, there is an unmet need for high quality surface reconstructions to model subcellular and synaptic interactions among neurons and glia at nanometer resolution. We address this need with VolRoverN, a software package(More)
This paper presents a concept study that demonstrates a transparent (non–intrusive to the application or the kernel) active replication and TMR–based fault tolerance in PC/Linux platforms. The target platform is the low–cost clusters of PCs that are increasingly more often found in the budget–oriented internet service industry. The solution we adopted is(More)
We present an algorithm to compute an approximation of the generalized Voronoi diagram (GVD) on arbitrary collections of 2D or 3D geometric objects. In particular, we focus on datasets with closely spaced objects; GVD approximation is expensive and sometimes intractable on these datasets using previous algorithms. With our approach, the GVD can be computed(More)
In this paper, we evaluate three storage systems for movieson-demand video servers. We show that striped disk farms, in which portions of movies are interleaved among disks, perform best. They achieve close to full disk utilization, good load balancing, and the lowest cost per video stream. Disk farms that store one movie per disk have lower performance,(More)
