TotalView Announces Beta for ReplayEngine 2.0
Featuring shared memory and Backwards Continue capability
NATICK, Mass., Nov. 18 -- TotalView Technologies, a provider of interactive analysis and debugging tools for serial and parallel codes, today announced the opening of beta for ReplayEngine 2.0. The new release will feature support for applications that use shared memory and memory linked to a device like a network card using DMA. Other new features include a Backwards Continue capability. With Backwards Continue users can easily use data watch points to go directly from an unexpected bit of data at the crash site back to the point at which that data originated, even if the program had been writing to an unrelated pointer in another thread. This release continues to expand the range of MPI environments supported to include low latency configurations of Open MPI, MPICH2, and MVAPICH and Intel MPI.
ReplayEngine's record and deterministic replay capability captures the execution history of Linux programs, making it available for diagnosis with TotalView. The reverse debugging approach allows developers to step freely both forwards and backwards through program execution, drastically reducing the amount of time invested in troubleshooting defective code and understanding complex program behavior.
"Shared memory and DMA technologies are critical for MPI users. Industry leading MPI libraries frequently use these techniques when they deliver low latency intra- and inter-node communication." said Chris Gottbrath, director of product management at TotalView Technologies. "With this release our many HPC customers developing MPI applications can radically simplify their debugging by simply stepping backwards from the crash to the error that caused it. I am proud to encourage all MPI developers working on the Linux x86 or x86-64 platform to participate in this beta."
