README for Global Arrays and ARMCI Benchmarks
=============================================
How to Build the Benchmarks
---------------------------
The Makefile assumes you have installed GA 5-1 or later which also installs
the "ga-config" helper script. This script contains the various linker,
compiler, and preprocessor flags used to build GA. You must specify the path
to ga-config or else edit the Makefile to add the necessary flags manually.
For example::
make GA_CONFIG=/path/to/ga/install/bin/ga-config
make CPPFLAGS=-I/path/to/ga/install/include LDFLAGS=-L/path/to/ga/install/lib LIBS=-lga
It is *much* easier to use the installed ga-config script!
Directory Contents
------------------
-armci_perf.c ARMCI benchmark where proc 0 sequentially communicates with
the other 1..P procs
-config.fh a few necessary preprocessor symbols for Fortran
-config.h a few necessary preprocessor symbols for C
-ga_perf.c GA benchmark demonstrating the overhead added by the GA layer
compared to the "armci_perf.c" benchmark
-ga_ptp.F GA benchmark where all procs communicate
-ga_shift.F GA benchmark using a shift algorithm
-LICENSE legal information about these files
-Makefile makefile for building these benchmarks
-mp3.fh message passing init and termination symbols for Fortran
-mp3.h message passing init and termination symbols for C
-README this file
-testutil.fh contains a few Fortran declarations for extra functions
