Summary 0000800: INCOMPATIBLE: new approach to multithreading
Description ALGLIB 3.13.0 and earlier versions used single-threaded code by default. Multithreaded processing had to be activated manually by calling "smp_" versions of ALGLIB functions, with default option to utilize all cores except for one.

Since ALGLIB 3.14.0, there is no "smp_"-prefixed versions of its functions. By default library uses serial processing, but you can indicate that you want to perform parallel execution either by enabling parallelism at global level with setglobalthreading() function/method, or by enabling it at call-local level by passing alglib::parallel with other function parameters.

By default library tries to utilize all cores (when parallel processing is activated). You can change number of worker threads with setnworkers() function/method.
