THREAD CONTEXT RESTORATION IN MULTI-THREADING COMPUTER SYSTEM Russian patent published in 2018 - IPC G06F9/46 

FIELD: computing; counting.

SUBSTANCE: invention relates to a computer system and a computer-implemented method for thread context restoration in a configuration. System comprises a configuration comprising a core configurable between a single thread (ST) mode and a multithreading (MT) mode, the ST mode addressing a primary thread and the MT mode addressing the primary thread and one or more secondary threads on shared resources of the core, and a multithreading facility configured to control utilisation of the configuration to perform a method comprising disabling the one or more secondary threads , based on switching from the MT mode to the ST mode in response to a reset or disabling the configuration, querying, during execution in ST mode, a last-specified maximum MT level to determine a last-specified program-specified maximum thread ID of the configuration, and obtaining the thread context of the one or more secondary threads by executing a set MT instruction to resume the MT mode and accessing the thread context of the one or more secondary threads based on being in the resumed MT mode.

EFFECT: technical result is to provide support for multi-thread data processing.
