A no-busy-wait balanced tree parallel algorithmic paradigm
Uzi Vishkin · 2000
Suppose that a parallel algorithm can include any number of parallel threads. Each thread can proceed without ever having to busy wait to another thread. A thread can proceed till its termination, but no new threads can be formed. What kind of problems can such restrictive algorithms solve and still be competitive in the total number of operations they perform with the fastest serial algorithm for the same problem?
