- .SH NAME
- loop_o \- report timing overhead
- .SH SYNOPSIS
- .B loop_o
- .SH DESCRIPTION
- .B loop_o
- reports the
- .IR for ()
- loop overhead associated with measuring timing intervals.
- This is critical mostly for experiments which measure very
- fast operations, such as memory loads, and which haven't
- been designed to minimize the loop overhead effects by
- some form of manual loop unrolling.
- .SH OUTPUT
- The output is reported in microseconds as an float:
- .IP ""
- \fC0.000005\fR
- .SH ACKNOWLEDGEMENT
- Funding for the development of
- this tool was provided by Sun Microsystems Computer Corporation.
- .SH "SEE ALSO"
