A collaboration of researchers, developers, and users working to make parallel tools responsive to user needs Software tools for high performance computing (HPC) have not kept pace with the dramatic hardware improvements of recent years. Existing parallel tools do not match the preferences or working habits of the scientists and engineers who develop most HPC […]

Learn About The Lightweight Corefile Format

The lightweight corefile is a platform-independent format designed to contain snapshot information about the current location of a parallel application. The data elements include the current value of the program counter, the contents of invocation stack frames, and a reason code for program failure. It is flexible enough to support a wide variety of platforms, […]

One particularly frustrating aspect of parallel programming is that when your program crashes or hangs, it’s difficult or impossible to determine how far execution got. System messages are notoriously cryptic about program failures. Even if you’ve inserted print statements to keep track of progress, that final (and most important!) line may be stuck in a […]
