I tried to profile my application with "sprofile" program but in this way my application doesn't find an input file. My application named "shallow_water" is in "home/roberto/shallow_water_old_old_version/shallow_water" folder where there is also the input file.

I tried

./sprofile -o "/home/roberto/output.csv" "/home/roberto/shallow_water_old_old_version/shallow_water/shallow_water"

and then

./sprofile -o "/home/roberto/output.csv" -w "/home/roberto/shallow_water_old_old_version/shallow_water" "/home/roberto/shallow_water_old_old_version/shallow_water/shallow_water"

do you open with relative address? because most likely you just need chenge current working directory. so run sprofile with absolute path and you program with relative.

I ran from sprofile folder, as you can see  I wrote ./sprofile and then I tried setting working directory with -w.

I tried now to run sprofile with absolute path in the folder of my application and all worked but I don't understand why the second way in the first message is wrong, in that I set working directory with -w.

It's not really necessary to run sprofile from it's own folder. Does it work if you run sprofile from the folder you usually start your app in?

e.g.: /opt/AMDAPP/tools/AMDAPPProfiler-2.3/x86_64/sprofile -o "/home/roberto/output.csv" ./shallow_water

maybe bug in profiler

Thank you, this also works, the way I said that works n my previous message is identical but I used absolute path for the application, too. I didn't think I was already in the folder ...

Oh, true. Must have somehow skipped that part of your post on reading. Sorry for the spam.

Thanks for reporting this issue. We confirmed -w switch doesn't work for Linux version of APP Profiler. It will be fixed in the next release. To workaround the problem, you can add sprofile to your $PATH.

I have another problem now, I don't understand how to use -k and -c parameters: using -k all I don't know where output files should be and I don't know how counterfile has to be.

[lbin]

kernel files(cl, il, isa) should go to the same path as your perf counter output file. If no output file is specified, they should go to home directory.

-c takes a path as input

You can create your counter file anywhere you want.

For example:

sprofile -k all -c ~/mycounters.txt myApp appArgs
