1. A method for managing a plurality of translation lookaside buffers, each translation lookaside buffer including a plurality of translation lookaside buffer entries and being associated with a corresponding processing element of a plurality of processing elements, the method comprising: issuing, at a first processing element of the plurality of processing elements, a first instruction for invalidating one or more translation lookaside buffer entries associated with a first context in a first translation lookaside buffer associated with the first processing element, the issuing including: determining, at the first processing element, whether or not a state of an indicator indicates that all translation lookaside buffer entries associated with the first context in a second translation lookaside buffer associated with a second processing element are invalidated; if the state of the indicator indicates that all translation lookaside buffer entries associated with the first context in the second translation lookaside buffer are not invalidated: sending a corresponding instruction to the second processing element of the plurality of processing elements, the corresponding instruction causing invalidation of all translation lookaside buffer entries associated with the first context in the second translation lookaside buffer, and changing a state of the indicator to indicate that all translation lookaside buffer entries associated with the first context in the second translation lookaside buffer are invalidated; and if the state of the indicator indicates that all translation lookaside buffer entries associated with the first context in the second translation lookaside buffer associated with the second processing element are invalidated: suppressing sending of any corresponding instructions for causing invalidation of any translation lookaside buffer entries associated with the first context in the second translation lookaside buffer to the second processing element.
