PIPS - suite of parallel optimization solvers mainly for stochastic optimization problems consisting of the following solvers:
i. PIPS-IPM - parallel MPI+OpenMP interior-point for stochastic LPs and convex QPs
ii. PIPS-S - parallel MPI implementation of the revised simplex method
iii. PIPS-NLP - parallel MPI interior-point for structured NLPs

# INSTALATION Instructions
####################################################################################
Building PIPS-S only can be achieved via
1) cmake -DBUILD_ALL=OFF -DBUILD_PIPS_S=ON <path_to_CMakeLists.txt>
or
2) including "set(BUILD_ALL OFF); set(BUILD_PIPS_S ON)" in a toolchain file, then
invoking
cmake -DCMAKE_TOOLCHAIN_FILE=<path_to_toolchain_file> <path_to_CMakeLists.txt>
Same applies to PIPS-IPM and PIPS-NLP (option names BUILD_PIPS_IPM and BUILD_PIPS_NLP,
respectively).
General instalation instructions
1. Install package wget, cmake, mpich2, and boost.
You can get them via the following command (xxx stands for the name of the package):
In Linux(Ubuntu): apt-get install xxxx
2. Go to the following folders and run the script wgetXXX.sh
ThirdPartyLibs/ASL
ThirdPartyLibs/CBC
ThirdPartyLibs/ConicBundle
ThirdPartyLibs/METIS
For an example, use command "sh wgetASL.sh" in the folder ThirdPartyLibs/ASL
3. Download MA27 and MA57 from HSL and put the source code in the correct folder.
(See ThirdPartyLibs/MA27/README.txt and ThirdPartyLibs/MA57/README.txt for more details.)
4. Assuming we are trying to install PIPS in the folder PIPSMAINPATH/build_pips, where
PIPSMAINPATH is the root instalation folder, use the following commands in the PIPSMAINPATH
folder to configure and install PIPS:
mkdir build_pips
cd build_pips
cmake ..
make
5. The build system will install executables from three sources: PIPS-IPM, PIPS-S and PIPS-NLP.
