Record and replay debugging race conditions and deadlocks in Linux applications.
ReplayEngine's deterministic replay capability records the execution history of your program and makes that history available for diagnosis with
. This new approach—working back from a failure, error, or crash to its root cause—eliminates the need to restart your program repeatedly with different breakpoint locations. The ability to do reverse debugging, stepping freely both forwards and backwards through program execution drastically reduces the amount of time invested in troubleshooting your code.
ReplayEngine can be used to debug applications written in C, C++ or Fortran and compiled with many of the compilers supported by TotalView on Linux x86 or Linux x86-64 platforms. ReplayEngine supports debugging MPI parallel, multi-threaded, and hybrid. ReplayEngine also allows long-running applications to be recorded, discarding the oldest part of the history when the space required for storing execution history would exceed user-specified limits.
