Commit: r1057: Add --max-jobs option to request concurrent processing of maps.
Version 1057 was commited by markb on 2009-06-03 11:26:34 +0100 (Wed, 03 Jun 2009) Add --max-jobs option to request concurrent processing of maps. Processing of the maps is handled concurrently by a pool of top-level threads. The number of threads in the pool can be specified explicitly with the --max-jobs=N option. Specifying just --max-jobs will set the number of threads equal to the number of CPUs available.

Specifying or specifically not specifying? I'm confused: What should be done to get one thread on a single core machine, or two threads on a dual core? _______________________________________________

Hi Lambertus,
Specifying or specifically not specifying? I'm confused: What should be done to get one thread on a single core machine, or two threads on a dual core?
Use --max-jobs. To summarise: If --max-jobs is not specified, you get 1 thread no matter how many cores you have. If --max-jobs is specified, you get as many threads as you have cores. If --max-jobs=N is specified, you get N threads. The help blurb says this in another way. Cheers, Mark
