  • gem5 standard library overview

    The gem5 standard library, introduced in v21.1 and fully released in v21.2, aims to enhance gem5 users’ productivity by providing commonly used components and features. Tutorials are available to help users utilize the library for creating gem5 simulations, including syscall emulation and full-system simulations. The library offers modularity and extensibility. The central component of the…

  • VNET vs VC in gem5 Garnet NoC

    When one is first introduced in Garnet NoC, he might find confusing the terms VNET and VC. A simple explanation follows. VNET (Virtual Network) can be considered a separate physical channel which carries a specific type of messages. More specifically, VNET is directly related with the Cache Coherence protocol that is used by the user.…

  • Why is gem5 still single threaded?

    gem5 simulator is not inherently multithreaded for several reasons: It’s important to note that while the core Gem5 simulator is primarily single-threaded, researchers and developers can leverage distributed computing techniques and parallel execution to run multiple Gem5 instances in parallel, simulating multiple cores or systems concurrently. This approach can achieve some level of parallelism while…

  • What drives today’s HPC

    High-Performance Computing (HPC) is a field that continually evolves to meet the growing demands of scientific research, industrial applications, and various other computational challenges. Several factors are driving the current development of HPC: These factors, among others, are propelling HPC development, leading to innovations in hardware, software, and algorithms to meet the ever-increasing demands for…
