Compiling the Shared Memory Version.

Please note that the shared-memory parallel version has not been tested in Version 4.0 and may be broken. Please let me know if you want to use it and I will get it working.

• To compile a shared memory version, obtain an OpenMP compliant compiler, such as Omni . Other options are listed at the OpenMP Web site .

• Follow the instructions above for configuring the makefile. Set the variable CC to the compiler name in the makefile and compile as above. Note that if you have previously compiled the sequential version, then you should first type make clean_all, as this version uses the same directories. With one thread allowed, it should run exactly the same as the sequential version so there is no need to compile both versions.

• Voila, you have a shared memory parallel solver. As above, to test SYMPHONY, a sample MPS file called sample.mps is included with the distribution. To specify the file name, use the -F command-line option, i.e., type bin.$(ARCH)/$(LP_SOLVER)/mip -F sample.mps in the SYMPHONY-4.0/USER directory. To obtain more MPS data files for further testing, download the MIPLIB library.

• That's it! Now you are ready to develop your own application by modifying the files in the SYMPHONY-4.0/USER directory and it's subdirectories. See Section 4.2 for more information.
