An Example: High Performance Linpack
This is a patch to the original High-Performance Linpack Benchmark
(HPL Version 1.0a)
that enables the usage of non-blocking collective operations. This patch
is based on Christian Siebert's "native MPI_Bcast() patch"
for HPL and adds another broadcast option that lets the user select
non-blocking collective operation implemented in LibNBC.
Applying the patch (pseudo-script):
mkdir linpack
cd linpack
# download original HPL
wget http://www.netlib.org/benchmark/hpl/hpl.tgz
# unpack HPL
tar xzf hpl.tgz
# download patch
wget http://www.unixer.de/research/nbcoll/hpl/hpl-1.0a-NBC.patch
cd hpl
# patch HPL
patch -p 1 < ../hpl-1.0a-NBC.patch
# create Make.Linux according to HPL documentation
# add LibNBC include (nbc.h) to CFLAGS
# add LibNBC library (libnbc.a) to LDFLAGS
# compile
# create HPL.dat (select 6 or 7 for Bcast) and run
