Abstract in LaTeX format:
In the {\em consensus} problem in a system with $n$ processes, each process
starts with a private input value and runs until it chooses irrevocably a
decision value, which was the input value of some process of the system;
moreover, all processes have to decide on the same value.
This work deals with the problem of {\em wait-free} ---fully resilient
to processor crash and napping failures--- consensus
of $n$ processes in an ``in-phase" multiprocessor system.
It proves the existence of a solution to the problem in this system by
presenting a protocol which ensures that a process will
reach decision within at most $n(n-3)/2 +3$ steps of its own in the worst case,
or within $n$ steps if no process fails.
