, and the number of floating and integer repl ace-adds . - U - CHAPTER 6 THE SOFTSOAP SIMULATOR The SOFTSOAP simulator is a set of FORTRAN callable subroutines that enable a user to run code intended for WASHCLOTH without getting his hands really dirty. The SOFTSOAP package has the same entry points as WASHCLOTH. Once code has been modified to run under WASHCLOTH it can be debugged for a one processor system by running under SOFTSOAP. Since SOFTSOAP executes the code rather than emulating the i...nstructions, it does not incur the factor of 50 times penalty associated with WASHCLOTH. In addition, since no distinction is made between public and private memory, the user need not switch to "no private" mode for diagnostic prints. SOFTSOAP has its limitations. SOFTSOAP does not fully support the trap mechanism of WASHCLOTH due to the limited use of this feature for single processor execution. Only replace-add instructions may be trapped and in this case the instruction cycle count is only approximate.
