Message-ID: <1991May25.220250.11321@cs.yale.edu> Date: 25 May 91 22:02:50 GMT Sender: news@cs.yale.edu (Usenet News) Distribution: usa Organization: Laboratory for Computational Chemistry, Yale University Lines: 56 Nntp-Posting-Host: doctor.chem.yale.edu Hi, I've been using pixie to profile my files for a long time now. I recently tried it, and when time came to use prof -pixie file, I get: (twnew is the mainline, wpot is the only subroutine) prof -pixie bestc wpot_ is an alternate entry within twnew_ (bestc.f) ---------------------------------------------------------------------------- * -p[rocedures] using basic-block counts; * * sorted in descending order by the number of cycles executed in each * * procedure; unexecuted procedures are excluded * ---------------------------------------------------------------------------- 255733799 cycles cycles %cycles cum % cycles bytes procedure (file) /call /line 156061559 61.03 61.03 156061559 34 twnew_ (bestc.f) 91665000 35.84 96.87 35 5 sqrt (sqrt.s) 7994250 3.13 99.99 19 12 d_sign (d_sign.c) etc... wpot is responsible for ~60% of the CPU time, but everything is now glommed into the mainline. Programs with more subroutines do the same thing, the mainline is assigned the sum of all of the individual routine times. I used to get a nice breakdown of individual routine percentages. I can get the procedure numbers from pixstats, but what I really want is the h[eavy profile, which pixstats wont give. What has changed? Is this a bug or a feature?
