1. A multi-core processor, comprising:

  • a first physical partition comprising a first main processing element;

    a second physical partition comprising a second main processing element and a group of sub-processing elements, the group of sub processing elements being designated as a pseudo main processing element by the first main processing element in the first physical partition for controlling a logical partition of sub-processing elements; and

    a pseudo virtualized control thread associating the pseudo main processing element of the second physical partition with the logical partition of sub-processing elements, the pseudo virtualized control thread providing control, to the pseudo main processing element of the second physical partition, over operation of the logical partition of sub-processing elements, and the pseudo virtualized control thread further configured to collect computation results from the sub-processing elements of the logical partition.
