Klocwork supports multicore and multiprocessor machines, running parallel analysis for improved performance.
On the desktop, parallel analysis is enabled by default. Klocwork sets the number of compilation jobs to an appropriate level, based on the number of available processor cores. If you don't have a multicore or multiprocessor machine, then a serial analysis is run.
For integration build analysis, use the --jobs-num option of kwbuildproject to configure parallel analysis.
