As networks approach gigabit performance, supercomputer host interfaces are becoming the communication bottleneck. The Network Interface Unit (NIU) is a highperformance host interface for Pixel Planes 5, a custom graphics supercomputer. The design offers both performance and programmability through a balance of ahtamarshaling hardware and an embedded(More)
This paper describes the design, implementation, and use of a model of sporadic tasks in the Real-Time Mach kernel (MK83) [15]. The purpose of this exercise was two-fold. First, was our desire to provide a programming model in real-Time Mach (RT-Mach) that was better suited to the demands and requirements of applications that must execute in response to(More)
As fiber-optic gigabit networks are being deployed, supercomputer network interfaces are becoming the communication bottleneck. The Network Interface Unit (NIU) is a high-performance network interface for Pixel Planes 5, a custom, message-based multicomputer. The design offers both performance and programmability through a balance of data-handling in(More)
We compare implementation of Raw and Internet protocols (TCP, UDP) on a programmable HIPPI host-interface called the Network Interface Unit. The network interface unit connects Pixel-Planes 5, a message-based graphics multicomputer, to a wide area gigabit network called VISTAnet. The BISDN network consists of a SONET cross-connect switch and an ATM switch.(More)
