when porting(fortran) codes to Linux/Intel andgettingthem running
Ihad toset the optimization level to -O0 at least for some files.
Otherwise the codes crash. (Note that the codes in question
run without problems on UNIXes using different compilers and
high optimization levels). Strangely there is no difference
between 7.1 and 8.0 Intel compilers in that respect.
Obviously -O0 optimized code runs slow (which is most strongly
noticeble on Itanium).
Can I manually enable some of -O1 features but not all
so thatto figure out what kind of optimization crashes the codes?
Unfortunately all my attempts to improveperformance of the codes
compiled with -O0by adding other switches did not make significant difference.
