SunSoft Performance WorkShop for Fortran 90 1.0 is the first in a family of products targeted at the developer building applications for the high performance computing market. New features are a Fortran 90 compiler, and a math library optimized for the SPARC(R) platform. The product components are
The system parameters on Solaris, using the SunSoft Fortran 90 compiler are given here. Compare the corresponding table for NAG, Digital or Cray.
Sun, Digital, and Cray use the number of bytes as the KIND-parameter. SunSoft permits the values 1, 4, and 8 for logical variables (with the same result as for the default value 4), the values 1, 2, and 4 for integers, the values 4 and 8 for floating point values, and also the values 4 and 8 for complex values. The names int7, int15, and int31 are mine.

You can get the compiler switches with the command f90 -flags. I here reproduce the most important of these.
-ansi: Report non-ANSI extensions.
-c: Suppress linking, produce .o files
-e: Recognize extended (132 character) source lines
-fast: Specify common set of performance options
-fixed: Interpret all Fortran source files according to
fixed form rules
-flags: Print summary of compiler options
-fnonstd: Non-standard initialization of floating-point
hardware
-fnonstop: Execute without trapping on invalid, overflow,
and divide by zero
-fns: Turn on non-standard floating point mode
-free: Interpret all Fortran source files according
to free form rules
-g: Generate debugging information used by dbx
-help: Print summary of compiler options
-LX: Passed to the linker to add X to the library
search path
-lX: Read object library (for ld)
-MX: Add directory X to module search path
-o file: Set name of output file
-O: Generate optimized code
-onetrip: Perform DO loops at least once
-p: Prepare object code to collect data for
profiling with prof
-pg: Prepare object code to collect data for
profiling with gprof
-qp: Same as -p
Produce file of type (may also be spelled -qproduce)
-Qproduce .f90: .f90 (f90 source, Free Form)
-Qproduce .f: .f (f90 source, Fixed Form)
-Qproduce .lst: .lst (f90 listing)
-Qproduce .o: .o (Object file)
-Qproduce .s: .s (Assembler source)
-S: Product .s file only (do not assemble or link)
-s: Strip the executable
-time: Report the execution time for each component
-V: Show version number of each invoked component
-v: Verbose mode
-w: Suppress compiler warning messages
