Intel Fortran for Linux 8.1.081 Disgnostic Tests Results

For information...

Intel Fortran for Linux 8.1.081 just came out. Our diagnostic test
results for that compiler (and others) appear at:
http://ftp.aset.psu.edu/pub/ger/for...est/results.txt

Relative to our diagnostic benchmarks, very little changed
from Version 8.0.049.

It appears that the compiler people are working first on
performance (which shows), and then when that's done
hopefully they will work on run-time diagnostics
(which can really help the integrity of one's code).
The compiler options -C and -WB , which will catch at
run-time uninitialized variables and a plethora of other
run-time errors hopefully is still on the back burner
for Version 8 (these options are (were) implemented in
Version 7.x).

Version 8.1 supports OpenMP (if one happesns to
have dual processors). The option -parallel
tells the compiler itself to figure out how best
to parallize the code.

The documentation is quite extensive.

Finally some new compiler options were added. Two are:
-zero which zeros out local, static, scalars.
-xB optimizez code for the Pentium M.

I've also updated our P4 benchmarks for the new version. I hope to get
results on AMD systems soon.

Yeah - I go away for a couple of days and look what happens... Windows too. I
think you meant 8.1.018, though.

You can read more about Intel Fortran 8.1 at
http://www.intel.com/software/produ...ilers/index.htm

In addition to the usual enhancements in run-time performance and bug fixes,
this release offers compilation for Windows and Linux systems based on
Intel(R) processors with Intel Extended Memory 64 Technology (Intel EM64T).
And, yes, it will also compile for that other 64-bit extended chip... The
compiler for Intel EM64T is a separate download from Intel Premier Support.
For best performance on processors with Intel EM64T, use -xP (/QxP). For that
other processor, use -xW (/QxW). Note that for Windows users, the OS build
you need is available from MSDN.

-WB actually turns OFF diagnostics for compile-time detected bounds
violations. It is expected to reappear within the next month or two. We
share your opinion of the worth of additional correctness diagnostcs and hope
to improve in this area.

I guess another important question is: when will it become available to
non-commercial users (i.e. poor grad students like me. ;-) I remember that
there was supposed to be some plan to offer the latest versions more
frequently to the non-comm users?

Steve: Thanks. Sometimes I'm so dyslectic.

You all may be interested to see Arnaud Desitter's benchmarks using
the new Intel compiler, Version 8.1.018:
http://ftp.aset.psu.edu/pub/ger/for...ing/results.txt

Ifort did quite well here too.

The 8.1 compiler is available to non-commercial users. The way the free
non-commercial licenses work is that you are eligible for the compiler that is
current at the time you get the license, but not for future updates. I don't
know offhand what controls how often you can apply for a new license.

The compiler for Intel EM64T is not on the "Limited Support" list yet, but
should be soon.

Regarding updates - the issue was that the e-mail you receive when you get a
license points you to a compiler that can be quite old. You could always
register your license and download a current compiler through Premier Support.
What we will be doing is "refreshing" the initial download more often.
