The SSUMES programs are designed to run on any platforms where ANSI C++ and FORTRAN77/90 compilers are available, but have been extensively tested only with GNU compilers and Intel compilers on Linux and Windows.

  The current version of SSUMES programs use about 1.4GB (or 2.5 GB for 64-bit version) of physical memory to store the working matrices for calculation.   The problem size (matrix size) is limited to 12,000 (16,000), that is, the maximum size of the matrix is 12,000 × 12,000 (or 16,000 × 16,000).   The problem size can be changed by rebuilding the executables after changing the constants found at the beginning of the umolPorb class declarations in ssulibc.h.
