Abstract
In one embodiment, the present invention includes a method for determining a vulnerability level for an instruction executed in a processor, and re-executing the instruction if the vulnerability level is above a threshold. The vulnerability level may correspond to a soft error likelihood for the instruction while the instruction is in the processor. Other embodiments are described and claimed.
