Distributed Verification of Multi-threaded C++ Programs

Distributed Verification of Multi-threaded C++ Programs. Stefan Edelkamp joint work with Damian Sulewski and Shahid Jabbar. Motivation: IO-HSF-SPIN. Same states in both parts. Arrives at the final state. Large jumps due to 2nd heuristic. Current state. Already seen final state.

Quiz 3

Consider a system with a physical memory latency of 200nsec, and which uses paging with page tables in memory. If the TLB hit rate is 90 %, then what is the average latency of a paged memory reference? Assume that a TLB hit takes no time for address translation
