Using the M5 Simulator ISCA 2006 Tutorial Sunday June 18th, 2006
This half-day tutorial will introduce participants to the M5 simulator system. M5 is a modular platform for computer system architecture research, encompassing system-level architecture as well as processor microarchitecture.
We will be releasing version 2.0 of M5 in conjunction with this tutorial. Features new in 2.0 include:
- Multiple ISA support (Alpha, MIPS, and SPARC)
- An all-new, execute-in-execute out-of-order SMT CPU timing model, with no SimpleScalar license encumbrance
- All-new, message-oriented interface for memory system objects, designed to simplify the development of non-bus interconnects
- More extensive Python integration and scripting support
Because the primary focus of the M5 development team has been simulation of network-oriented server workloads, M5 incorporates several features not commonly found in other simulators.
- Full-system simulation using unmodified Linux 2.4/2.6, HP Tru64 5.1, or L4Ka::Pistachio) (Alpha only at this time... coming in the future for MIPS and SPARC)
- Detailed timing of I/O device accesses and DMA operations
- Accurate, deterministic simulation of multiple networked systems
- Flexible, script-driven configuration to simplify specification of complex multi-system configurations
- Included network workloads such as Apache, NAT, and NFS
- Support for storing results from multiple simulations in a unified database (e.g. MySQL) for automated reporting and graph generation
M5 also integrates a number of other desirable features, including pervasive object orientation, multiple interchangeable CPU models, an event-driven memory system model, and multiprocessor capability. Additionally, M5 is also capable of application-only simulation using syscall emulation.
M5 is freely distributable under a BSD-style license, and does not depend on any commercial or restricted-license software.
Researchers in academia or industry looking for a free, open-source, full-system simulation environment for processor, system, or platform architecture studies. Please register via the ISCA 2006 web page.
