Summary. In a shared­memory distributed system, n
independent asynchronous processes communicate by read­
ing and writing to shared variables. An algorithm is
adaptive (to total contention) if its step complexity de­
pends only on the actual number, k, of active processes
in the execution; this number is unknown in advance
and may change in different executions of the algorithm.
Adaptive algorithms are inherently wait­free, providing
fault­tolerance in the presence of an arbitrary number of
crash failures and different processes' speed.
A wait­free adaptive collect algorithm with O(k) step
complexity is presented, together with its applications
in wait­free adaptive algorithms for atomic snapshots,
