Shadow v1.6.1 released, adds multi-threading support

Rob just tagged Shadow v1.6.1, and added a link on the download page. This is really more like a pre-1.7.0 release, but he wanted to get out some exciting new support for running multi-threaded simulations earlier!

This release includes:

  • Support for running multi-threaded simulations! (use the “-w” flag to specify the number of worker threads)
  • A few bugfixes

In preliminary testing, the biggest improvements have been seen when using between 4 and 8 worker threads. Happy simulating!
