This paper describes an implementation of the Mach IPC abstraction on a network. Our implementation, called Mach NetIPC, is done in the context of the x-kernel, which provides a networking subsystem for Mach. The paper motivates the design choices we made, describes the x-kernel protocol graph that implements the design, and reports on the performance of the resulting system.

Ernst Mach (1838-1916) was the first to discover an irregular reflection phenomenon of shock waves, as is well known in our community. In fact, this occurred in 1875-three years earlier than usually assumed in the literature [1]. However, it is correct that Mach gave the physical interpretation of this phenomenon in 1878 [2]. Since Mach's discovery of an irregular shock reflection pattern some ...

Computational fluid dynamics simulations using the WENO-LF method are applied to high Mach number nonrelativistic astrophysical jets, including the effects of radiative cooling. Our numerical methods have allowed us to simulate astrophysical jets at much higher Mach numbers than have been attained (Mach 20) in the literature. Our simulations of the HH 1-2 astrophysical jets are at Mach 80. Simu...

Due to the increasing growth of processing cores in complex computational systems, all the connection converted bottleneck for all systems. With the protection of progressing and constructing complex photonic connection on chip, optical data transmission is the best choice for replacing with electrical interconnection for the reason of gathering connection with a high bandwidth and insertion lo...

In this chapter, we propose a new concurrent programming approach called MACH (multi-agent extended chemical abstract machine). MACH extends the chemical abstract machine with multiple coexisting agents. This paper focuses on the design, implementation, and verification of MACH. The aim of MACH is to develop a reactive programming language based on an interactive computational model, which we b...

Shock reflection is a fundamental phenomenon in studying compressible flow. Since Ernst Mach first studied the reflection phenomena of shock waves in 1878 [6] great amount of research works on such phenomena, mainly experiments and computations, was proceeded. In gas dynamics when a shock wave meets an obstacle in its propagation process the shock reflection occurs generally. There are various ...
