Postgresql & AMD x86-64

From
Justin Clift
Date:
Hi guys,

Does anyone want remote access to the upcoming AMD 64 bit architecture,
to make sure PostgreSQL runs well on it?

It's only via remote access at present, but the AMD guys are willing to
help us out here.

Regards and best wishes,

Justin Clift

Justin,

I apologize for the delayed response.  Unfortunately, at the moment I
don't have a system available to send you.  If I could get you access to
a machine remotely, would that be useful to you?  I will need to check
machine availability before I can promise you anything, but I'm willing
to be your sponsor in the AMD Developer Center and approve a request for
access.

Hi Andreas,

Have you heard anything back from the AMD guys in relation to this?

We've not heard a single thing from them.

:-(

Regards and best wishes,

Hi folks,

We recently built a dual K8D-based Opteron box running Linux in 64-bit
mode (Debian 'testing' distribution with newly compiled binutils, gcc,
and various support libraries for amd64 architecture).

The Postgres 7.3.3 "port" was simply a matter of setting the appropriate
flags to take of the biarchectecture nature of the Linux port.  (that is,
"-m64" to generate 64 bit code and either "gcc -m64" or "ld -melf_x86_64"
for linking").  There were no other issues in the compile.  In the
install, I had to re-init due to the incompatibility of pg_control.

All the regression tests went smoothly (the one "failure" was in geometry
and is due to round off in the least sig figs of the doubles in the Point
structure or machine zero differences).

I compared a simple query on local data in both 32bit mode and 64bit mode;
the execute time difference was not significant but this was not a compute
intensive verification (summing up column values in a table).  We have
some other 32-bit amd machines here; I would be happy to try a few other
tests.

Good job, developers!!!

Re: [HACKERS] Postgresql & AMD x86-64

From
"Martin D. Weinberg"
Date:
Bruce,

I didn't change the source tree at all.  I used:

env CFLAGS='-O3 -m64' LD='/usr/bin/ld -melf_x86_64' ./configure --with-CXX --without-zlib

with the experimental gcc and bintils from www.x86-64.org.  I needed
--without-zlib because I don't have a 64 bit compile yet for zlib.

make
make install-all-headers
make check CC='gcc -m64'

The last one is needed to make sure that the shared library gets made
in the amd64 architecture.

That's it!

BTW, see Jeff Baker's nearby report in pgsql-general that s_lock.h needs
to be tweaked to use spinlocks on this platform.  If you're using
semaphores instead then you're taking a big performance hit.

Re: Postgresql & AMD x86-64

From
"Martin D. Weinberg"

Hi folks,

We recently built a dual K8D-based Opteron box running Linux in 64-bit
mode (Debian 'testing' distribution with newly compiled binutils, gcc,
and various support libraries for amd64 architecture).

The Postgres 7.3.3 "port" was simply a matter of setting the appropriate
flags to take of the biarchectecture nature of the Linux port.  (that is,
"-m64" to generate 64 bit code and either "gcc -m64" or "ld -melf_x86_64"
for linking").  There were no other issues in the compile.  In the
install, I had to re-init due to the incompatibility of pg_control.

All the regression tests went smoothly (the one "failure" was in geometry
and is due to round off in the least sig figs of the doubles in the Point
structure or machine zero differences).

I compared a simple query on local data in both 32bit mode and 64bit mode;
the execute time difference was not significant but this was not a compute
intensive verification (summing up column values in a table).  We have
some other 32-bit amd machines here; I would be happy to try a few other
tests.

Good job, developers!!!

Interesting.  The compiler doesn't do x86_64 by default --- you have to
enable it in the compile.

Any idea how to handle this in our builds?  It doesn't seem like a
property of the OS as much as a property of the compiler --- we
already do 64-bit on some platforms without flags.

What is the full ac_cv_host value in config.log?

    ac_cv_host=i386-pc-bsdi4.3.1

I assume there is something special in the first field before the dash
that could trigger these compile/link flags automatically.

As I already mentioned, the s_lock.h changes will appear in 7.4 and are
in CVS now.
