VTUNE-like Profiling Tools for Unix?
Milo_Mindbender asks: "I'm working on a rather large scale C++ graphics/networking project under Linux and am really missing having a low level code profiler like Intel's VTUNE available. In particular, I am looking for the ability to profile not just CPU use, but using the CPU performance counters to profile stuff like L1/L2 cache misses, pipeline stalls...etc. The other VTUNE capability I'm missing is the way it profiles the whole system, so the profile includes time spent in drivers, OS and everything else along with your program's profile. Has anyone seen anything like this for Linux? I hear Intel is working on VTUNE for Linux but they don't seem to have released anything yet."
but that's the price you pay for using C++. C is going to be a lot better choice for low-level programming and profiling.
I would strongly suggest that you port the performance-critical portion of your app to Windows. You can give it a null display interface, fake input, etc, just enough to keep the inner loop(s) running while you run VTune over it.
Despite the previous poster's comment about C++ being bad for performance, a well-designed C++ app also makes it easy to set up portable test code as described above. This is one of the many reasons for which C++ is more and more often used for performance-critical work such as video game authoring.
ARTED? aahahahahaha
More radio songs are banned in the US in response
to the terrorist attacks.
They are mostly B-side songs, therefore little known.
I doubt anyone would miss them, but censorship is always a bad thing.
Here are some of them:
Alice in Chains - Rust Monster
AC/DC - Santa Claus
Atomic Kitten - Nice butts
Bangles - Head full of Air
Black Sabbath - White Friday
Bush - Dyba
Elton John - Bad Taste
Garbage - Apple
Korn - With P
Led Zeppelin - lleh ot yawriats
Lenny Kravitz - Cut my hair
Limp Bizkit - Teenage dwarfs
Louis Armstrong - I wasn't on the Moon
Madonna - Sexual Obsession
Michael Jackson - From Black to White
Megadeth - Illiterate
Metallica - Trash Noise
Nina - Wrong name
Nine Inch Nails - Hit by a Hammer
Jimmy Hendrix - Grassheads
John Lennon - It's only the manager
Queen - King
Pink Floyd - Another sick in the toilet
Prince - Don't know my name
Rammstein - Magensucht
Rage against the machine - Fuck this car
Red Hot Chilli Peppers - Curry
REM - Loosing my temper
Rolling Stones - Old Farts dancing
Santana - Sleep
Soundgarden - Caput Guitar
The Beatles - Jonny dead
The Doors - We are stuck
U2 - Bloody, bloody boring
Zombies - We not dead
Fight intolerance, racism and censorship !
You might also want to check out KProf at http://kprof.sourceforge.net/. It's a nice GUI for gprof and functioncheck. FunctionCheck is much more detailed than gprof, but it requires re-linking the app. See http://www710.univ-lyon1.fr/~yperret/fnccheck/prof iler.html for more details.
Take a look at cacheprof.
www.cacheprof.org
It's a very nice tool for profiling C-code.
What is Cacheprof?
Cacheprof is a tool designed to help programmers quantify and understand the cache behaviour of programs and algorithms. With this knowledge, you might be able to modify your code to be more cache-friendly and thereby faster. Cacheprof will run your program, simulating a cache of your choice, and will annotate each line of source code with the number of memory references and the number of cache misses caused by that line. It will also print summaries per-procedure, and for the program as a whole. Finally, it will count the number of instructions executed, which can be very useful.
