The GAUSS Profiler

1 Using the GAUSS Profiler
The GAUSS TM
Profiler
There are two steps to using the GAUSS Profiler: collection and analysis.
1.1 Collection
To collect profiling information, you must run your GAUSS program in tcollect, an executable shipped
with GAUSS 8.0 that is identical to tgauss except that it generates a file containing profiling information
each time it is run:
tcollect -b myfile.e
The output displayed by tcollect includes the name of the output file containing the profiling information.
tcollect output files have with a gaussprof prefix and a .gco extension.
1.2 Analysis
To analyze the information stored in the tcollect output file, you must run the gaussprof executable,
which is also shipped with GAUSS 8.0, on that file. gaussprof produces an organized report, displaying
the time usage by procedure and by line.
Assuming that running myfile.e in tcollect produced an output file called gaussprof 001.gco, you could
analyze the results in that file as follows:
gaussprof gaussprof_001.gco
The syntax for gaussprof is:
gaussprof [flags] profile data file ...
where [flags] may be any of the following:
-p profile procedure calls
-l profile line numbers
-h suppress headers
-sp order procedure call sort order where order contains one or more of the folllowing:
e exclusive time
t total time
c number of times called
1

p procedure name
a ascending order
d descending order (default)
Columns are sorted all ascending or all descending.
-sl order line number sort order where order contains one or more of the folllowing:
t time spent on line
c number of times line was executed
f file name
l line number
a ascending order
d descending order (default)
The default, with no flags, is: -pl -sp dep -sl dtf.
Columns are sorted all ascending or all descending.
