par2tbb

par2 creates redundancy to verify and repair errors in files. "par2tbb" uses the Intel Threading Building Blocks library to parallelize this computation.

The TBB documentation recommends that managing the number of threads should be left to the library, and not be done explicitly by the user. Because the default strategy is to spawn as many threads as possible, a high thermal load results for long running computations. The resulting fan activity is distracting if par2 is run in the background while the computer is also used interactively.

This version of "par2tbb" has been modified to provide an additional command line argument -p<n> to specify the number of threads explicitly. Choosing a small number of threads keeps the fan noise to a minimum and avoids CPU throttling.
