Field protection against thread loss in a multithreaded computer processor |
摘要 |
A method, apparatus, and a program product to protect against thread loss in a multithreaded computer processor. The processor may experience the failure of one or more threads; in accordance with the invention, a functional test can be run to determine which thread is experiencing the failure. If the thread failure results the failure of a register/array that is uniquely associated with the thread, then the invention will disable access to those register/arrays. Each thread may have its own set of register/arrays or it may be uniquely assigned to one of a plurality of storage elements in a multithreaded register/array. Using this invention, a processor may continue processing other threads and the instructions and data associated with the disabled or defective thread can be rerouted.
