View Full Version : Announcing the Release of ReplayEngine 2.0

06-09-2011, 10:40 AM
With ReplayEngine 2.0 it is possible to do reverse debugging with MPI applications making use of the native performance of low-latency Infiniband interconnects. The supported hardware configurations are Infiniband cards by Mellanox or QLogic and the following MPI libraries:

MVAPICH2 1.5 and 1.6
Open MPI 1.4.2
Intel MPI 4.0

If you use TotalView to start the job the debugger sets some important environment variables. If you want to use the "proctable" launch mechanism you may need to set those environment variables yourself. See the section “Using ReplayEngine with Infiniband MPIs?" (http://www.roguewave.com/portals/0/products/totalview-family/totalview/docs/8.9.1/User_Guide/totalviewug-mpi-debugging.09.51.html) in the TotalView User Guide (in the PDF that's chapter 6, page 125).

Fire up your favorite MPI application then replay it and tell us what you think!

ReplayEngine 2.0 is distributed with TotalView 8.9.1. Current users with maintenance are encouraged to obtain copies of the updated software for 30 days at the following URL


after that time, contact Rogue Wave to get access to the latest and greatest ReplayEngine.
