Re: [pooma-dev] ICC and POOMA--versions, CHEETAH, MM, MPICH?

[Paul A. Renard]

George:

I compile pooma-2.4.0 with:
    configure --arch LINUXICC --opt --suite
LINUXicc-opt

    setenv POOMASUITE LINUXicc-opt

     make

this makes an optimized (no exceptions) version.

By the way, I reported about a month ago some trouble I was having with
icc.  It was not producing code as good as KCC.  However, after
sending POOMA, and my test problem to Intel, they were able to match the
run time performance of KCC-produced code, but they needed to make some
compiler tweaks which they promise will be included in icc
8.0   I was seeing about a 4X slowdown with icc, which had
nothing to do with compiler switches, it had do to with placement new not
being declared inline in the icc distribution, icc's failure to elide
no-op destructors, and possible failure to elide no-op
constructors.   The compiler people claim that version 8.0 will
produce code as good as KCC, but be ready for somewhat disappointing
results with 7.1
