Simultaneous multithreading (SMT) is a technique for improving the overall efficiency of superscalar CPUs with hardware multithreading. SMT permits multiple independent threads of execution to better use the resources provided by modern processor architectures .
Simultaneous and heterogeneous multithreading (SHMT) is a software framework that takes advantage of heterogeneous computing systems that contain a mixture of central processing units (CPUs), graphics processing units (GPUs), and special purpose machine learning hardware, for example Tensor Processing Units (TPUs).
This article lists concurrent and parallel programming languages, categorizing them by a defining paradigm.Concurrent and parallel programming languages involve multiple timelines.
Another area of research is what type of events should cause a thread switch: cache misses, inter-thread communication, DMA completion, etc. If the multithreading scheme replicates all of the software-visible state, including privileged control registers and TLBs, then it enables virtual machines to be created for each thread. This allows each ...

The threaded programming model provides developers with a useful abstraction of concurrent execution. Multithreading can also be applied to one process to enable parallel execution on a multiprocessing system. Multithreading libraries tend to provide a function call to create a new thread, which takes a function as a parameter.
PHP—multithreading support with parallel extension implementing message passing inspired from Go [16] Pict—essentially an executable implementation of Milner's π-calculus; Python — uses thread-based parallelism and process-based parallelism [17] Raku includes classes for threads, promises and channels by default [18]
Not thread safe: Data structures should not be accessed simultaneously by different threads. Thread safe, serialization : Use a single mutex for all resources to guarantee the thread to be free of race conditions when those resources are accessed by multiple threads simultaneously.
