[PerfSuite-users] threshold

[Ryszard <rys...@ce...>]

Hi everybody,

I am playing with a psrun and profiling.=20

Here is a little background about my application. I have a simulation =
and its executable file is dynamically linked with about 80 libraries. =
More or less, the application spends about 2 seconds in order to open =
all shared libraries, before a real running (before main function).=20
Simulations works well, but there is a problem with the psrun and the =
profiling. The psrun tool stops and does not run the simulations. The =
psrun exits after the fork() function.=20

The running environment and the config file as well is exactly the same =
as in case of the profiling another simulation which works good. I =
started to change threshold parameter in the config file from 50000 to =
200000 and it started work. The problem is that this trick does not give =
a stable solution, because from time to time the profiling job still =
does not work.=20

Do you have any ideas, what could be wrong here? Please contact me if =
you need more information. Thank you in advance for your help.

Best regards,
Ryszard.
