Abstract
Transparently executing applications among cores in a multi-processor system includes monitoring elements associated with each processor which align execution of threads within corresponding cores of the processors. Alignment is accomplished by monitoring system resource utilization by each core, comparing process counters associated with corresponding cores, and comparing data sets in and out during application frame switching. In a further aspect, inputs are coordinated by a synchronization element. Likewise, outputs for corresponding cores are compared to ensure no corrupted data is propagated.
