Engines¶
The execution of the multistarts can be parallelized in different ways, e.g. multi-threaded or cluster-based. Note that it is not checked whether a single task itself is internally parallelized.

class
pypesto.engine.
MultiProcessEngine
(n_procs: Optional[int] = None)[source]¶ Bases:
pypesto.engine.base.Engine
Parallelize the task execution using multiprocessing.
- Parameters
n_procs – The maximum number of processes to use in parallel. Defaults to the number of CPUs available on the system according to os.cpu_count(). The effectively used number of processes will be the minimum of n_procs and the number of tasks submitted.

class
pypesto.engine.
MultiThreadEngine
(n_threads: Optional[int] = None)[source]¶ Bases:
pypesto.engine.base.Engine
Parallelize the task execution using multithreading.
- Parameters
n_threads – The maximum number of threads to use in parallel. Defaults to the number of CPUs available on the system according to os.cpu_count(). The effectively used number of threads will be the minimum of n_threads and the number of tasks submitted.

class
pypesto.engine.
SingleCoreEngine
[source]¶ Bases:
pypesto.engine.base.Engine
Dummy engine for sequential execution on one core. Note that the objective itself may be multithreaded.
