Thread: Postgresql & AMD x86-64
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 -------- Original Message -------- Subject: RE: Postgresql AMD x86-64 Date: Fri, 4 Apr 2003 10:29:24 -0800 From: marc.miller@amd.com To: justin@postgresql.org CC: aj@suse.de, chris.rimer@amd.com 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. -----Original Message----- From: Justin Clift [mailto:justin@postgresql.org] Sent: Monday, March 10, 2003 7:31 PM To: Andreas Jaeger Subject: Re: AMD x86-64 Hi Andreas, Have you heard anything back from the AMD guys in relation to this?

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!!!

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.
regards, tom lane
The s_lock.h change will be in 7.4. --------------------------------------------------------------------------- Tom Lane wrote: > "Martin D.

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.
