Horizontal architectures can control several functional units independently, and usually have a single flow of control. As such, they exploit only the finer parallelism, and a large number of functional units is useless when the code contains control or data dependencies. The performance in these cases can be increased, with the same total hardware, if the functional units are divided in groups...

Adaptive Optics Scanning Laser Ophthalmoscopy was used to noninvasively acquire videos of single-file flow through live human retinal parafoveal capillaries. Videos were analyzed offline to investigate capillary flow dynamics. Certain capillaries accounted for a clear majority of leukocyte traffic (Leukocyte-Preferred-Paths, LPPs), while other capillaries primarily featured plasma gap flow (Pla...

We consider wireless ad hoc networks in which each connection (file) traverses only one hop. We assume that files arrive for service at each link and a file departs when all its packets have been transmitted. The file size distribution can be arbitrary, but the file sizes are assumed to be bounded. We assume that a window flow control protocol regulates the injection of packets from each file i...
