Claims (17)

1. Компьютерно-реализуемый способ для диспетчеризации множественных потоков в конфигурации, содержащей ядро, активированное для действия в режиме единственного потока (ST) и в многопоточном (МТ) режиме, причем ядро содержит физические потоки, причем способ содержит:
- выпуск выполняющейся на ядре в режиме ST хост-программой команды запуска виртуального выполнения (запуска VE) для диспетчеризации на ядре гостевого логического объекта, причем гостевой логический объект включает в себя, полностью или частично, гостевую виртуальную машину (VM), и выполнение ядром команды запуска VE, причем выполнение содержит:
- получение первого описания состояния из местоположения, заданного командой запуска VE, причем первое описание состояния имеет гостевое состояние,
- выявление на основании гостевого состояния того, включает ли гостевой логический объект в себя единственный гостевой поток или множественные гостевые потоки,
- на основании гостевого состояния и при выявлении того, что гостевой логический объект включает в себя множественные гостевые потоки, запуск гостевых потоков на ядре в режиме МТ, причем гостевые потоки выполняются независимо друг от друга, и
на основании гостевого состояния и при выявлении того, что гостевой логический объект включает в себя единственный гостевой поток, запуск гостевого потока на ядре в режиме ST.
2. Способ по п. 1, причем ядро включает в себя компьютерные команды, управляющие использованием совместно используемых ресурсов физическими потоками, когда ядро находится в режиме МТ.
3. Способ по п. 1, причем хост-программа администрирует гостевой логический объект как единственное логическое ядро, когда ядро находится в режиме МТ.
4. Способ по п. 1, причем хост-программа использует маску допустимости потока для указания на допустимость одного или нескольких гостевых потоков в гостевом логическом объекте.
5. Способ по п. 1, причем способ, кроме того, содержит выход из всех из одного или нескольких гостевых потоков в гостевом логическом объекте до возврата управления к хост-программе.
6. Способ по п. 1, причем на основании включения в состав гостевого логического объекта множественных гостевых потоков данные состояния для одного потока содержатся в первом описании состояния, а данные состояния для каждого из одного или нескольких дополнительных потоков содержатся в дополнительном описании состояния.
7. Способ по п. 1, причем на основании включения в состав гостевого логического объекта множественных гостевых потоков, по меньшей мере, часть данных состояния, которые являются общими для всех гостевых потоков, сохраняется в единственном местоположении.
8. Способ по п. 6, причем первое описание состояния и дополнительные описания состояния сохраняются по меньшей мере в одной из числа структур кольца и списка.
9. Способ по п. 1, содержащий, кроме того, выполнение выхода без действий, что включает в себя выход из гостевого потока на основании запроса от другого гостевого потока.
10. Система, содержащая средства, выполненные для осуществления всех этапов способа согласно любому предшествующему пункту относительно способа.
