[photran-dev] Photran Indexer Measurements
|
I spent today speeding up Photran's indexer. It's not particularly
fast, but I think it's usable now. At some point in the future, I could
get another 10-25% improvement by changing the way we search for
references. Here are the measurements for a few of our internal test
programs.
The first three represent fairly typical Fortran applications.
Parallel Ocean Program
77,900 LOC in 68 files
38.9 seconds indexing (several module loading errors)
IBEAM (Post-Preprocessing)
62,026 LOC in 220 files
51.2 seconds indexing
Atmospheric Dispersion Simulation
52,968 LOC in 29 files
19.1 seconds indexing (3 fixed form parsing errors)
The last two programs are anomalies of sorts. FMLIB has 36,895 lines in
one file while another 10,944-line file uses the same (large) module
repeatedly in every subroutine. LAPACK is nearly a million lines of
code, but you would generally expect to index it only once.
FMLIB
56,418 LOC in 5 files
1:18.7 indexing
LAPACK
910,973 LOC in 2,811 files
6:26.5 indexing (many fixed form parsing errors)
Details follow.
=========================================
Measurements performed using org.eclipse.photran.cmdline/VPGStats with
-Xmx256M
Java(TM) SE Runtime Environment (build 1.6.0_13-b03-211)/Java
HotSpot(TM) 64-Bit Server VM (build 11.3-b02-83, mixed mode) on Mac OS X
10.5.7
2 GHz Intel Core 2 Duo, 2 GB 667 MHz DDR2 SDRAM
Lines counted using:
LINES=0; for file in `find . -iname "*.f*"`; do F=`cat $file | wc -l`;
LINES=`expr $LINES + $F`; done; echo "Total Lines: $LINES"
