Abstract
We establish trade­offs between time complexity and
write­ and access­contention for solutions to the mu­
tual exclusion problem. The write­contention (access­
contention) of a concurrent program is the number
of processes that may be simultaneously enabled to
write (access) the same shared variable. Our notion
of time complexity distinguishes between local and re­
mote references to shared memory. We show that,
for any N­process mutual exclusion algorithm with
