DISPATCHING MULTIPLE THREADS IN COMPUTER Russian patent published in 2018 - IPC G06F9/455 

FIELD: computing; counting.

SUBSTANCE: invention relates to dispatching multiple threads in a computer. Computer system comprises a configuration with a machine enabled to operate in a single thread (ST) mode and a multithreading (MT) mode. In addition, the machine includes physical threads. Machine is configured to perform a method that includes issuing a start-virtual-execution (start-VE) instruction to dispatch a guest entity having multiple logical threads on the core. Guest entity includes all or a part of a guest virtual machine (VM), and issuing is performed by a host running on one of the physical threads on the core in the ST mode. Executing of the start-VE instruction by the machine includes mapping each of the logical threads to a corresponding one of the physical threads, initialising each of the mapped physical threads with a state of the corresponding logical thread, and starting execution of the guest entity on the core in MT mode.

EFFECT: technical result is enabling the dispatching of a multi-thread guest virtual machine.
