WRENCH is a simulation framework for building simulators of Workflow Management Systems. WRENCH implements high-level simulation abstractions on top of the SimGrid simulation framework, so as to make it possible to build simulators that are accurate, that can run scalably on a single computer, and that can be implemented with minimal software development effort.

This release includes a series of new features and bug fixes, including:

  • #37: Energy consumption by hosts and support for power state management
  • #60: Virtual machine management support including shutdown, start, suspend, and resume operations
  • #13: Enriched set of simulation events in the simulation output
  • #59: Command-line options
  • Bug fixes: #38, #63, #64, #66
  • Code improvements: #36, #61

Note: WRENCH 1.1 requires SimGrid 3.20 or higher.

On this minor bug fix and small improvements release, we provide:

  • #52: Ability to declare VM creation overhead in seconds to Cloud/VirtualizedCluster service
  • #58: Ability to load batch workload trace file in JSON "batsim" format
  • Bug fixes: #51, #53, #54, #56, and #57

Note: WRENCH 1.0.1 requires SimGrid 3.20 or higher.

WRENCH's 1.0 release

WRENCH enables novel avenues for scientific workflow use, research, development, and education in the context of large-scale scientific computations and data analyses. WRENCH is an open-source library for developing simulators. WRENCH exposes several high-level simulation abstractions to provide high-level building blocks for developing custom simulators.

This release provides a set of (simulated) services that can be instantiated on the simulated platform:

  • Compute Services (multi-core multi-host, virtualized cluster, cloud computing, and batch computing)
  • Storage Service (including support for scratch space for computing nodes)
  • File Registry Service (file replica catalog)
  • Network Proximity Service (monitors the network and provide a database of host-to-host network distances)
  • Workflow Management Systems (WMSs)
