                    TINKER Notes for SGI under MIPS Compiler
                    ----------------------------------------

          This subdirectory contains a set of script files that can
          be used to build the TINKER program package on a Silicon
          Graphics workstation under Irix 6.5 using the SGI MIPSPro
          Fortran 7.2.1 compiler.

          In order to improve performance on SGI MIPS series CPUs the
          -mips4 compiler flag should be added for R5K and R10K-based
          machines. The corresponding flag for R4K CPUs is -mips2 and
          for R3K is -mips1. Executables created with these flags are
          not downward compatible, so -mips4 executables will not run
          on R4K-based systems, and so forth.

          If some or all of the executables fail via a segmentation
          fault or mystereous loader error, check the limits for your
          processes by issuing the "limit" command at a C shell prompt
          (or similar under other shells). On many workstations these
          limits are set to quite small values for ordinary users. To
          eliminate the problem issue the following three commands:

                         limit filesize unlimited
                         limit datasize unlimited
                         limit stacksize unlimited

          These same commands can also be put in your .cshrc file or
          equivalent startup file to be run at login time.
