ScaLAPACK Installation
NOTE: These intructions were updated in June 2006. They may not be kept up-to-date. Refer to the ScaLAPACK website for more recent and more complete instructions.
ScaLAPACK must be available on your system before Amesos_Scalapack or Amesos_Mumpscan be used. ScaLAPACK is provided in many high performance libraries, including the Cray Scientific Library (-lsci), Silicon Graphic's (-lsdsm), Hewlett Packard's MLIB, Intel's MKL. Some IBM scientific libraries also support ScaLAPACK. Many high performance computer installations include ScaLAPACK. Hence, it is worth checking to see if ScaLAPACK is already installed on your computer.
Even if ScaLAPACK is available on your system, you may need to build it from the original sources if you are using a different fortran compiler.
To install ScaLAPACK on your system you will need the BLAS and the BLACS. The BLAS are almost certainly installed on your system, but the BLACS are often not installed unless SacaLAPACK is.
To install the BLACS on your system:
• Obtain the distribution from the BLACS website You will need both mpiblacs.tgz and mpiblacs-patch03.tgz. Getting blacstester.tgz is also wise.
• Untar these three into the same directory.
• Edit Bmake.inc, starting from one of the templates in BMAKES/Bmake.inc.
o Set BTOPdir to point to the directory that the BLACS are in (generally ends in BLACS)
o Set F77, CC, MPIINCdir and MPILIB.
 MPIINCdir should be set to a directory including mpif.h.
 MPILIB can be left blank if F77=mpif77 and CC=mpicc
o Set PLAT to a character string representing your platform (optional).
o Follow the directions in BLACS/INSTALL/README. The BLACS/INSTALL directory contains several small routines which will help you set Bmake.inc variables INTFACE and TRANSCOMM and may warn you of more serious problems with your mpi implementation. Note: the executables are placed in the EXE subdirectory.
o Type "make mpi" in the BLACS directory to build the BLACS.
o Type "cd TESTING; make" to build the BLACS tester (note, the blacs tester takes close to a minute to compile)
o Run the blacs tester on 4 processes. On many machines, this can be done with: "cd EXE; mpirun -np 4 xFbtest_MPI-...-0" or "cd EXE; mpirun -np 4 xCbtest_MPI-...-0"
o Don't give up if the BLACS tester fails. It is important that the testers link, but sometimes blacs installations that cause the BLACS tester to fail still work. On one system, the BLACS tests all gave this error message: "MPI Error, rank:0, function:MPI_TYPE_INDEXED, Invalid count argument" but the ScaLAPACK and Amesos_ScaLAPACK installation tests both passed.
To install ScaLAPACK on your system, install the BLACS first(see above), then:
• Obtain the latest distribution from the SCALAPACK website. As of May 2006, the latest distribution is scalapack-1.7.3.tgz, but you should check for patches and later distributions.
• Untar the ScaLAPACK code: "tar xzf scalapack-1.7.3.tgz". Typically this is done in the same directory that you untarred the BLACS code (it will create a scalapack-1.7.3 directory).
• Edit SLmake.inc.
o home to the directory that the ScaLAPACK code resides in. For version 1.7.3, this will end in scalapack-1.7.3. For earlier versions, it tyically ends in SCALAPACK.
o Set PLAT to the same staing that you set it to for the BLACS in the Bmake.inc file (optional).
o Set BLACSdir to the directory that the BLACS library files are in (typically ends in BLACS/LIB)
o Set F77, CC. Typically (almost always) these are the same compilers used to compile the BLACS.
o Set CDEFS to the flags you wish to pass to the C compiler (typically this includes the flags you set in INTFACE in Bmake.inc).
o Set SMPLIB to point to your mpi library (typically -lmpi). May be left blank if you use F77=mpif77 and CC=mpicc
o Set BLASLIB to point to the BLAS library.
o Set BLACSFINIT, BLACSCINIT and BLACSLIB. If you set BLACSdir and PLAT right, you may not have to change these.
• Type: "make" in the same directory that SLmake.inc is in to build the ScaLAPACK library. Takes several minutes.
• Check to see that libscalapacl.a was built in this directory.
• Type: "cd TESTING/LIN; make" to build the linear solver testers. Takes several minutes.
• Type: "cd .." to change back to the TESTING directory. Then run xdlu < LU.dat on four processes. On many computers this can be done with "mpirun -np 4 xdlu
• The results should end with:
Finished 240 tests, with the following results:
240 tests completed and passed residual checks.
0 tests completed and failed residual checks.
0 tests skipped because of illegal input values.

END OF TESTS.
