%X In modern cluster systems message passing functionality is
often off\-loaded to the network interface card for
efficiency reasons. However, this limits the amount of
memory available for message buffers. Unfortunately, buffer
insufficiency can cause an otherwise correct program to
deadlock, or at least slow down. Hence, given a program
trace from an execution in an unrestricted environment,
determining the minimum number of buffers needed for a safe
execution is an important problem. We present three related
problems, all concerned with buffer allocation for safe and
efficient execution. We prove intractability results for the
first two problems and present a polynomial time algorithm
for the third.
