<p>Methods and systems for scheduling threads in a multi-threaded computer system use a modified move-to-rear list scheduling algorithm. Threads are ordered in a service list according to a virtual time value. System threads always retain a virtual time value. For system threads, the virtual time value serves as a priority. For user threads, the virtual time value is incremented after the thread has received a share of access to the CPU resource. The invention can provide soft real time capability for application software. At the same time, it satisfies system threads which must be executed with some urgency. The thread scheduler of the invention may be used to advantage in the Java multi-threading framework.</p> |
