OpenMP (Open Multi-Processing) is an application programming interface (API) that supports multi-platform shared-memory multiprocessing programming in C, C++, and Fortran, [3] on many platforms, instruction-set architectures and operating systems, including Solaris, AIX, FreeBSD, HP-UX, Linux, macOS, and Windows.
Due to Python’s Global Interpreter Lock, local threads provide parallelism only when the computation is primarily non-Python code, which is the case for Pandas DataFrame, Numpy arrays or other Python/C/C++ based projects. Local process A multiprocessing scheduler leverages Python’s concurrent.futures.ProcessPoolExecutor to execute computations.
A concurrent programming language is defined as one which uses the concept of simultaneously executing processes or threads of execution as a means of structuring a program. A parallel language is able to express programs that are executable on more than one processor.
$ mpicc example.c && mpiexec -n 4 ./a.out We have 4 processes. Process 1 reporting for duty. Process 2 reporting for duty. Process 3 reporting for duty. Here, mpiexec is a command used to execute the example program with 4 processes, each of which is an independent instance of the program at run time and assigned ranks (i.e. numeric IDs) 0, 1 ...

Despite having an ".exe" file extension, native applications cannot be executed by the user (or any program in the Win32 or other subsystems). An example is the autochk.exe binary that runs chkdsk during the system initialization "Blue Screen". Other prominent examples are the services that implement the various subsystems, such as csrss.exe.
ThreadX is an embedded real-time operating system (RTOS) programmed mostly in the language C.It was originally released in 1997 as ThreadX when Express Logic first developed it, later it was renamed to Azure RTOS (2019) after Express Logic was purchased by Microsoft, [2] then most recently it was renamed again to Eclipse ThreadX (2023), or "ThreadX" in its short form, after it transitioned to ...
Specifically, a program is sequentially consistent if "the results of any execution is the same as if the operations of all the processors were executed in some sequential order, and the operations of each individual processor appear in this sequence in the order specified by its program".
