START VIRTUAL EXECUTION INSTRUCTION FOR DISPATCHING MULTIPLE THREADS IN COMPUTER Russian patent published in 2018 - IPC G06F9/30 G06F9/455 G06F9/50 

FIELD: computing; counting.

SUBSTANCE: invention relates to a virtual execution start instruction for dispatching multiple threads on a computer. System for dispatching multiple threads in a configuration comprising a core which includes physical threads and is operable in single thread (ST) and multithreading (MT) modes, a host program configured to start virtual execution (start VE) for dispatching a guest logical entity which includes a guest virtual machine (VM). VE start instruction is executed by the core and includes obtaining from said VE start instruction the location of the state description having the guest state. Execution includes identifying, based on the guest state, whether the guest logical entity includes a single guest thread or multiple guest threads, and based on the guest state and when it is determined that the guest logical entity includes a single guest thread or multiple guest threads, starting guest threads on the core in the MT mode or the ST mode.

EFFECT: technical result is a reduction of overhead of administering a hypervisor in a multithread environment.
