 Posted: Thu Sep 15, 2011 1:17 pm Post subject: Instrumentation Profiling on 32 bit |
 |
|
Can one do event or instrument profiling using the 32-bit based PGroup System? It said in some of the earlier documents that it was only available on the 64-bit system Then the more recent documents stopped saying that. I want to use Oprofile with it, of course.
Can this be done on 32-bit systems? Is it restricted to 64-bit systems?

Hi THX 1138,
OProfile-based sampling support is only available on 64-bit Linux. The simple interface to this is
- pgcollect -hwtime
- pgcollect -dcache
- pgcollect -icache
- pgcollect -allcache
There is a simple time-based sampling facility available via pgcollect that is support on all platforms, 32-bit and 64-bit. The interface to this is:
- pgcollect -time
Also available on 32-bit is instrumented profile using the "-Mprof" flag.
After any of these, run pgprof in the same directory to view the results:
- pgprof -exe myprog
