Very Computer

Sorry, I have not done it yet.

BTW, there is no instruction for proper installation
of libcpml.a.
I see /lib/libm.so.* and /usr/lib/libm.a in the original RedHat
distribution.  So what should I do to use libcpml.a?

Thank you.

Those who wants to benchmark the new library with the
Polyhedron's F77BENCH.ZIP on a Unix-like machine will find
ftp://penguin.kjist.ac.kr/pub/fortran.d/f77bench.tar.gz
useful and much more convenient than the original
zip file.  It's got a Makefile!

The way it was explained to me is that you're expected to just stick
libcpml.a in /usr/lib and use -lcpml in your link.  If you want to go
further and actually replace the Linux libm with libcpml (renaming it
in the process), go ahead, but we're not suggesting/recommending that
approach.

I have read Steve Lionel's reply on the above question of mine.
In fact, I replaced /usr/lib/libm.a with libcpml.a.
I am not sure.  But, I don't see any change (from libffm.a) in
the benchmark result after using libcpml.a.  Maybe I am
not using it properly.  BTW, I have installed GOTO's
other custom BLAS routines also.

Because the untared file is ready to compile and run, I would like
to ask people to obtain the benchmark results for all of us.

Thank you.

Certain speed advantages follow from linking different parts of
Joachim Wesner's libffm with cpml; the most dramatic that I have found comes
from pow.o. E.g.

g77 -o t.e t1.o t2.o -lcpml /usr/local/libffm.0.28/pow.o -lfm

is twice as fast for codes with intensive use of the pow routine.
Note that adding fm is crucial for allowing pow.o to find the
requisite calls (not that I understand this ordering of linkings).

The result of my fortran code with various math libraries.
I used egcs-1.1.1 and single precision and '-O3' option only.

- with 'libm'

87.123u 0.086s 1:27.54 99.6%    0+0k 0+0io 119pf+0w

- with 'libffm'

54.054u 0.053s 0:54.21 99.7%    0+0k 0+0io 120pf+0w

- with 'libcpml'

54.438u 0.074s 0:54.75 99.5%    0+0k 0+0io 122pf+0w

- on CrayT3E-900(450 MHz Alpha) with Cray's 'libfm' and CF90 compiler.
default double precision

62.93u 2.14s 1:13.12 89.0%

There is no difference between 'libffm' and 'libcpml' and two are still
slower than Digital Visual Fortran on Win/NT-alpha.

libfm.a used to exist for libffm.a 0.21.
libfm does not seem to exist in libffm.a version 0.28.
Are you sure that we still need libfm.a with libffm.a 0.28?
There was a newer verison of libm.a that is supposed to
be used with libffm.a 0.28.

So you are saying  that we need libfm.a back.
What is going on?

Thanks.

The compilers default to  link with the shared lib libm.so.*
Did you use the statically linked version libm.a?
(Try: ldd your_prog, there should be no libm.so.*)

Bye,

I just realized why nobody responded to my request for a
benchmark result.  My penguin did not accept anonymous
ftp login.  I thus moved the tar file to a new location.

ftp://infcom.kjist.ac.kr/pub/fortran.d/f77bench.tar.gz

Please try.

BTW, my penguin accepts anonymous ftp logins within
our domain.  So, I thought it would accept ftp-logins from
outside our domain.  Does it not?  Appaerenly not.
Redhat-5.1 was put on my Penguin.  What should I do
to accept anonymous ftp logins from outside of our
domain?

Thank you.

You probably have to play with the /etc/hosts.allow and
/etc/hosts.deny files.  On my Slackware box, the man
pages are found under hosts_access(5).

Comp.os.linux.setup would seem a more appropriate forum in
which to ask that question. However, I'd recommend asking
your local Linux gurus first. Two obvious places to look at
are /etc/hosts.{allow,deny} and (if you are using wu-ftpd)
the ftpaccess file. (I'm no longer sure of all the details,
and can't look them up right now since the system I'm writing this
on doesn't have wu-ftpd installed.)

It is also conceivable that your domain sits behind a firewall, with
direct inbound ftp disabled. Ask your network administrators.
