Virtual-Memory-Mapped Network Interfaces

Two virtual memory mapped network interface designs

In existing multicomputers, software overhead dominates the message-passing latency cost. Our research on the SHRIMP project at Princeton indicates that appropriate network interface support can signi cantly reduce this software overhead. We have designed two network interfaces for the SHRIMP multicomputer. Both support virtual memory mapped communication allowing user processes to communicate ...

Software Support for Virtual Memory-Mapped Communication

Virtual memory-mapped communication (VMMC) is a communication model providing direct data transfer between the sender's and receiver's virtual address spaces. This model eliminates operating system involvement in communication, provides full protection, supports user-level bu er management and zero-copy protocols, and minimizes software communication overhead. This paper describes system softwa...

Direct Device Assignment for Untrusted Fully-Virtualized Virtual Machines

The I/O interfaces between a host platform and a guest virtual machine take one of three forms: either the hypervisor provides the guest with emulation of hardware devices, or the hypervisor provides virtual I/O drivers, or the hypervisor assigns a selected subset of the host’s real I/O devices directly to the guest. Each method has advantages and disadvantages, but letting VMs access devices d...

A New Trust Model for B2C E-Commerce Based on 3D User Interfaces

Lack of trust is one of the key bottle necks in e-commerce development. Nowadays many advanced technologies are trying to address the trust issues in e-commerce. One among them suggests using suitable user interfaces. This paper investigates the functionality and capabilities of 3D graphical user interfaces in regard to trust building in the customers of next generation of B2C e-commerce websit...
