Introduction
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 discussing version 2.0 of the M5 simulator and specifically its new features including:
- Multiple ISA support (Alpha, ARM, MIPS, and SPARC)
- An execute-in-execute out-of-order SMT CPU timing model, with no SimpleScalar license encumbrance
- Message-oriented interface for memory system objects, designed to simplify the development of non-bus interconnects
- New caches models that are easier to modify
- New multi-level bus-based coherence protocol
- More extensive Python integration and scripting support
- Performance improvements
- Generating checkpoints for simpoints
- Full-system simulation using unmodified Linux 2.4/2.6, FreeBSD, or Solaris (More are on the way)
- 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
Intended Audience
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 ASPLOS 2008 web page.
Tentative Topics
The following topics will be discussed in detail during the tutorial:
