.TH Xmark 1 "x11perf 1.6.1" "X Version 11"
.SH NAME
Xmark \- summarize x11perf results
.SH SYNTAX
.B Xmark
datafile
.SH DESCRIPTION
.B Xmark
is a shell script that reads the indicated datafile and compiles a
benchmark which it writes to standard output.  It writes three
numbers:
.PP
.RS
A weighted performance number for the
.I x11perf
results.
.PP
A weighted performance number for a standard SparcStation 1, with
SunOS 4.1.2, X11R5 Xsun, and a CG3 dumb Color Frame Buffer.
.\" I assume the latter is a graphics card.
.PP
The Xmark, which is the ratio of the two numbers above.
.RE
.PP
The datafile must be an ordinary file, produced by x11perf in the
following way:
.PP
.BI "x11perf -display " display " -v1.3 -rop GXcopy GXxor -all > " datafile
.PP
It is possible to run the GXcopy and GXxor tests separately, as long as they
are concatenated to the same output file:
.nf
.BI "x11perf -display " display " -v1.3 -rop GXcopy -all > " datafile
.BI "x11perf -display " display " -v1.3 -rop GXxor -all >> " datafile
.fi
or
.nf
.BI "x11perf -display " display " -v1.3 -rop GXxor -all > " datafile
.BI "x11perf -display " display " -v1.3 -rop GXcopy -all >> " datafile
.fi
.SH FILES

.SH DIAGNOSTICS
.TP

cannot find the datafile named on its command line, or the datafile
is a special file such as a directory.
.TP
.BR "WARNING: datafile contains " nnn ", not 441 or 447 'trep' results;"
The file named on the command line does not seem to be a file generated
by x11perf in the expected way.
