[PerfSuite-users] problem about profiling fortran program with libpshwpc

[George M. <ge...@ma...>]

Dear all,

I am sending you an email because I have a problem to profile a fortran 
program with libpshwc. I can profile the program with psrun but because 
I want to profile specific blocks of the code only, I would like to use 
|PSF_hwpc_init(ierr) |etc.  The program is one from NAS Parallel 
benchmarks (FT) and when I compile it I see the errors

ft.f:(.text+0x24): undefined reference to `psf_hwpc_init_'
ft.f:(.text+0x76): undefined reference to `psf_hwpc_start_'
ft.f:(.text+0x2b7): undefined reference to `psf_hwpc_stop_'
ft.f:(.text+0x471): undefined reference to `psf_hwpc_shutdown_'

||I have included fperfsuite.h and I have linked with -lpshwpc -lperfsuite

Could you propose something to solve my problem?
Also a simple question: I am confused, PerfSuite measures with statistic 
sampling? I now that with multiplexing is less accurate. I ask because I 
want to count flops and I don't want to loose any info.

Thanks in advance,
Best regards,
George Markomanolis
