Purpose
This script file, openmp/run.sh, compiles and runs the
speed and correctness tests for using OpenMP.
The following are a list of parameters in this file that can
be changed by directly editing the file
(there are no command line parameters to the script):
Compiler Command
The following sets the name of the C++ compiler command:
compiler="g++"
Version Flag
The following compiler flag requests its version information:
version_flag="--version"
OpenMP Flag
The following compiler flag requests openmp support
You can run these tests with a compiler that does not support OpenMP
by setting this flag to "".
openmp_flag=""
For g++ version 4.1 and higher, you can use "-fopenmp" for this flag.
Other Flag
The following other flags will be used during compilation:
other_flags="-DNDEBUG -O2 -Wall"
Boost Directory
If the BoostDir
is specified on the
configure
command line,
you must add the corresponding include directory; e.g.,
if [ -d /usr/include/boost-1_33_1 ]
then
other_flags="-DNDEBUG -O2 -Wall -I/usr/include/boost-1_33_1"
fi
Number of Repeats
The following specifies the number of times to repeat
the calculation corresponding to one timing test.
If this
is equal to "automatic", the number of repeats is determined automatically.
If it is not equal to "automatic", it must be a positive integer.
n_repeat="automatic"
Number of Threads
The following determines a set of number of threads to test.
Each value in the set must be a positive integer or zero
(the value zero is used for dynamic thread adjustment).
If the
openmp_flag
is equal to "",
this setting is not used.
n_thread_set="0 1 2 3 4"
example_a11c
The following setting determine the corresponding command line
arguments for the example_a11c.cpp
program:
example_a11c_size="10000"
multi_newton
The following settings determine the corresponding command line
arguments for the multi_newton
program:
multi_newton_n_zero="10"
multi_newton_n_grid="40"
multi_newton_n_sum="10"
sum_i_inv
The following setting determine the corresponding command line
arguments for the sum_i_inv.cpp
program:
sum_i_inv_mega_sum="1"
Restrictions
Current this script only runs under the bash shell; e.g., it will not
run in an MSDOS box.
