# Makefile for UPC collective functions.  Produces upc_collective.o
# and, if you want, a main program for exercises various functions.
#
# P can be "PULL" or "PUSH".  See the README file for details.
# If P is undefined then it is set to PULL in each collective function.
#
# If N is null or N=0 compilation is done in the dynamic threads environment.
# If N>0 compilation is done in the static threads environment for N threads.
#
# Set DEBUG to _UPC_COLL_CHECK_ARGS to use upc_coll_err() to check function
# arguments.  Argument checking invokes two barriers.
#
# For example,  make P=PUSH N=4 DEBUG=_UPC_COLL_CHECK_ARGS
