Version 3.1 of Allinea DDT has been released with a set of novel features designed to both simplify and enable debugging of parallel and multithreaded applications. Among the new features are ‘sparklines’ that deliver zero-click graphical comparison across processes that automatically show data values, and an offline mode that enables users to debug overnight. Scalable tracepoints provide a fast and scalable alternative to using print/write for debugging, while always-on static analysis is included for auto-detection of common programming errors. Version 3.1 supports Nvidia Cuda 4.0 and 4.1 toolkits as well as co-array Fortran and UPC.
