How to use ocelot for the GPU runtime performance monitor

Hi, I would like to monitor some performance character such as memory
access rate, utilization of GPU(how many MP are used or how many SP
are used.). Where should I insert my printf statement code in the
ocelot source code? Thank you.

Ocelot includes multiple methods for running a CUDA program including a functional simulator and native GPU and CPU targets. The emulator has a trace generation interface ( http://code.google.com/p/gpuocelot/wiki/TraceGeneration ) that allows you to write a callback functor that can examine the state of the program and record metrics that are visible at the ISA level, but not the microarchitecture level. So you would be able to record the memory accesses that the program is making, but not the utiltization of the MPs. If you want to measure something at the microarchitecture level, you would want to either use an architecture simulator like MACSIM or GPGPU-SIM, or write a timing model for Ocelot. You could take a look at the cache simulator in Ocelot ( http://code.google.com/p/gpuocelot/source/browse/trunk/trace-generators/traces/implementation/CacheSimulator.cpp ) for an example of an existing timing model.

Regards,

Greg

Thanks, Now, I install ocelot and face a lot of problems.

Before install ocelot I need to install hydranize.

And I use svn checkout http://hydrazine.googlecode.com/svn/trunk/ hydrazine-read-only

to download it.

I sereach with google find the following installment command:

cd hydrazine; libtoolize; aclocal; autoconf; automake; ./configure; sudo make install

So I cd into the /hydrazine-read-only/hydrazine

and run the command sudo libtoolize and it work

and I run sudo aclocal it says :

aclocal: `configure.ac' or `configure.in' is required

Where is the configure? How can I install this correctly.

Thank you very much.

Hi Cheng,

Current versions of Ocelot (from svn and the most recent download)
include hydrazine automatically. You should just be able to run the
configure script and makefiles in the main Ocelot directory.

Regards,

Greg

Hi Greg,

Thank you for your answer. I have finished the installment and I take an example of the tracegenerater.

I run the tracegeneration example code published on the website. And I have the following

error:

-----------------------------------------------------------------------

sudaken11:~/Desktop/ocelot-1.1.560> ./tracegen

terminate called after throwing an instance of 'hydrazine::Exception'

what(): invalid value

Abort

-----------------------------------------------------------------------

what dose this error mean?

How can I handle this error?

Hi Cheng,

This error is reported directly from the CUDA driver, meaning that an
NVIDIA GPU device is selected. The error is more verbose in more recent
versions, but you can only run trace generators on the Emulator device.
You need to edit your configure.ocelot file to select the 'emulated'
device only.

Regards,

Greg

Hi Greg,

It seems there are some different between the ocelot-1.1.560.tar.bz2 from the websize directly and the ocelot download by SVN.

I reinstall with the the SVN version, and at the finial step "make" I have the following error:

========================================

hydrazine/implementation/ArgumentParser.cpp: In member function ‘void hydrazine::ArgumentParser::parse()’:

hydrazine/implementation/ArgumentParser.cpp:157: error: ‘exit’ was not declared in this scope

make[1]: *** [libocelot_la-ArgumentParser.lo] Error 1

make[1]: Leaving directory `/home/skkk/Desktop/gpuocelot/ocelot'

make: *** [all] Error 2

==========================================

Something wrong with the hydrazine, but the hydrazine should be automatinclly installed by ocelot.

How can I solve this error?

Thank you very much.

Try checking it out again.ï¿½ exit is included in cstdlib, which was not explicitly included in ArgumentParser.ï¿½ This builds successfully on every machine that I have tried without including it, but I added it anyways.ï¿½ Hopefully this will fix your issue.

Greg
