Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.
Messages are "chained" if there are only replies at the first level, i.e. 1/1.html, 1/1/1.html etc. In case of "chained" messages the message number is replaced by the icon and there is no indentation.

the most important parameter of a computer for speedup in MT (or multi-process) is the number of available cores. If you have 4 cores you can get at maximum a 4x speedup using all of them either with MT or with clones of your jobs.
For what concerns a good example for MT migration, please refer to example B5. Even if this is not specific to neutrons, it is a complete example and shows all components that are needed in an application, including ConstructSDandField.
