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,

Postgresql & AMD x86-64
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: [GENERAL] Postgresql & AMD x86-64
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.

The s_lock.h change will be in 7.4.

Re: [HACKERS] [GENERAL] Postgresql & AMD x86-64

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.

Re: [HACKERS] [GENERAL] Postgresql & AMD x86-64
The following patch automatically enables 64-bit mode on AMD opteron. 
We already had spinlock support for it, but I added some comments.

The big question is whether all the operating systems running gcc on
Opteron support the 64-bit flags, and if we want to enable them by
default on Opteron.

If either of these is false, I will need to add a configure flag to
control 64-bit Opteron mode, though we could probably automatically
detect if gcc understand the 64-bit flags.  Another question is whether
any OS reports ia64 without having gcc understand -m64.  I am sure there
are lots of non-ia64-aware OS's running on Opteron, but do any of those
report ia64 as their CPU?

This might be one of those patches that we apply and see what reports we
get during beta.

Sorry, I think I confused you:
ia64-* is Intel's Itanium system. They are 64-bit only cpus (the 32-bit 
emulation is too slow to be usable). It's supported by multiple 
operating systems, among them HP UX, Linux, Windows. As far as I can see 
it's supported directly, by 7.3.3, at least RedHat builds their ia64 
version without any patches.
x86_64 is AMD's Operon/Athlon 64 system. They support concurrent 32-bit 
and 64-bit. Right now only supported by Linux, BSD and Windows support 
expected soon.
Thus the test must be for "x86_64-*".

Martin: you are using debian-testing, correct? I've asked a Suse 
developer, and on their Linux distribution, -m64 is the default, i.e. 
you don't need any switches.

I am easily confused.  It certainly makes more sense fir ia64 to be
Intel, not AMD. :-)

I have applied the following patch to document the cpus supported by
each define.

Martin mentioned that he has applied a special 64-bit kit to do the
compile, so perhaps he needs it, but most will not.  I will keep the
patch around and see if others need it during beta.

This sort of thing belongs into the template file, not directly in
configure.in.

I knew you were going to say that, but which template file?  It is a
product of the cpu/compiler, not a specific OS.
