Simics Runtime Environment Homepage

Virtutech® Simics is a full system simulation platform, capable of simulating high-end target systems with sufficient fidelity and speed to boot and run operating systems and commercial workloads. Simics provides a controlled, deterministic, and fully virtualized environment for a variety of hardware and software engineering tasks.

Simics is a commercial program developed and sold by Virtutech and a license is required before using the it.

This page describes the use and installation of Simics in Grid environments based on NorduGrid ARC middleware. For a complete description of the Resource Specification Language, Information System, User Interface and the Grid Manager, see the NorduGrid documentation.

Interface definition

In the remote computing resources Simics RE initializes the following environment variables:

1. SIMICS_ROOT - Folder where images/ and simics-2.2.7/ are located.
2. SIMICS_VERSION - Holds the current Simics-version (2.2.7).

Use example
