[PerfSuite-users] libpshwpc; working around implicit variables?

[Tirath R. <ti...@tp...>]

Hi all,

To begin with, is it normal/explainable that running psrun in  
counting mode counts far more samples of a given event than when  
running in profile mode? For example, I've been getting the following  
with my program:

PAPI_L2_LDM:
Counting: 5452797 samples
Profil: 305 samples (total)

The case is similar for PAPI_RES_STL and PAPI_TOT_CYC, and I haven't  
tested any others yet.

I figured I'd try invoking libpshwpc directly in the program instead  
of relying on psrun... but that may not be so simple as the code I  
have to work with is some pretty old Fortran. I'm pretty new to  
Fortran, so I don't know how correct my analysis is, but I think the  
problem is the code I have to work with relies heavily on implicit  
variables. Here's what I get when trying to compile:

g77 -c -O2 -I/usr/local/include -malign-double -fautomatic -Wno- 
globals -fno-globals gamess.f
source/gamess.srcpp: In program `gamess':
source/gamess.srcpp:320:
          IMPLICIT DOUBLE PRECISION(A-H,O-Z)
          1
fperfsuite.h:45: (continued):
          integer PS_PID, PS_PPID, PS_PGRP, PS_SESSION, PS_TTY,
          2
Statement at (1) invalid in context established by statement at (2)
... (it goes on like that)...

Does anyone know of a workaround for situations like this?
