Any friendly Mac users out there?

[Tord Romstad]

I'm trying to generate universal binaries of the new Glaurung, but because I don't have any PowerPC or 32-bit intel Macs, and no Macs running Tiger, I can't test how it works. To save myself from the embarassment of releasing something that doesn't work at all, I'd like to find someone who could verify that my binaries run correctly on all combinations of CPUs (32-bit PowerPC, 64-bit PowerPC, 32-bit Intel, 64-bit Intel) and recent MacOS versions (10.4, 10.5).

A collection of Glaurung binaries can be found here. The downloadable file unpacks to two directories, "leopard" and "tiger", which contain binaries for the two platforms. Both directories contain five files:

• glaurung-intel-32, for 32-bit x86 CPUs.
• glaurung-intel-64, for 64-bit x86 CPUs.
• glaurung-ppc-32, for 32-bit PowerPC CPUs
• glaurung-ppc-64, for 64-bit PowerPC CPUs.
• glaurung-universal, a universal binary containing all of the above.

I'm looking for people who can verify that the binaries for the various CPU/MacOS version combinations work. Please test both the binary for your specific CPU (e.g. glaurung-ppc32 in the "tiger" directory for a G4 Mac running Tiger) and the universal binary for your OS version, and check that they both work and give similar N/s counts.

The Leopard Intel binaries are compiled with the Intel compiler, and are a lot faster (52% for the 32-bit version, 27% for the 64-bit version) than the Tiger Intel binaries, which are compiled with GCC (I haven't been able to compile a Tiger compatible binary with the Intel compiler, despite hours of frustrating work). Another somewhat annoying thing about the Tiger binaries is that they don't detect the number of CPUs correctly, and always start with a single search thread.

Hi Tord,
I just tested the binaries on my MacBook (10.5.2, Leopard, 2Ghz Intel Core 2 Duo). Only uci, ucinewgame, go infinite no throughout testing though.

-glaurung-intel-32, for 32-bit x86 CPUs. ->works and uses both cores (1.4Mn/s)
-glaurung-intel-64, for 64-bit x86 CPUs. ->works and uses both cores (1.9Mn/s)
-glaurung-universal ->works, and uses both cores (1.8Mn/s)

I also tried the Intel-compiles for Tiger and they run on Leopard as well but use only a single core.

best regards
Roman

Thanks, Roman!

Your setup is similar to mine (I have a MacBook 2.4 GHz Core 2 Duo and an iMac 2.8 GHz Core 2 Duo), so it is no suprise that everything appears to work.

I just tested the binaries on my MacBook (10.5.2, Leopard, 2Ghz Intel Core 2 Duo, both running Leopard). Only uci, ucinewgame, go infinite no throughout testing though.

No more thorough testing is required.

-glaurung-intel-32, for 32-bit x86 CPUs. ->works and uses both cores (1.4Mn/s)
-glaurung-intel-64, for 64-bit x86 CPUs. ->works and uses both cores (1.9Mn/s)
-glaurung-universal ->works, and uses both cores (1.8Mn/s)

Looks normal. On both of my machines, the MN/s count is approximately 0.95 x the clock frequency in GHz. It is slightly weird that the universal binary was a little slower than the 64-bit Intel binary; they should be identical. I guess there was just some random process which stole a few CPU cycles while you tested the universal binary.

I also tried the Intel-compiles for Tiger and they run on Leopard as well but use only a single core.

They use two cores if you set the "Threads" UCI option to 2 (there's no need to test this, I am 100% sure it is correct). The problem is that the technique I use to detect the number of CPU cores doesn't work in Tiger. When Glaurung can't detect the number of CPU cores, it defaults to a single search thread.

Unfortunately none of the Leopard versions works on my PowerMac G5.
The Tiger versions run fine with 1 (default) or 4 threads on Leopard 10.5.2

Andreas,

Thanks for the information. I was able to reproduce the problem with the 32-bit PowerPC binary by running it in Rosetta on my Mac. I am not sure what was wrong, but it turns out that the problem disappears when I compile with the -g flag. Really weird.

I have updated the Leopard PowerPC binaries. I hope at least the 32-bit version should work now (I have no way to test the 64-bit binary, because Rosetta doesn't support 64-bit PowerPC programs).

The performance of the quad G4 is a little disappointing. It is slower than Roman's 2 GHz Core 2 Duo.

I usually compile glaurung with
CXXFLAGS = -O3 -DNDEBUG -funroll-loops -fomit-frame-pointer -fstrict-aliasing -fno-exceptions -fno-rtti -Wall -arch ppc64 -mtune=G5 -fast


Ok, all three (universal included) versions work now:

glaurung-ppc-32 (nps 1485873)
glaurung-ppc-64 (nps 1865006)

I can confirm the new batch working on Leopard on my MacPro and Mac G5

Initial testing results indicate that Glaurung is the strongest chess app available for 8-core MacPro

some early results:
Match Glaurung 080430 vs. HIARCS 11.2 MP: final score 39-18-43
Match Glaurung 080430 vs. Deep Shredder 11 UCI: final score 6-2-2

Looks like the 080513 is performing stronger yet.

Great! Then all that remains is to find out whether the Tiger binaries work.

Initial testing results indicate that Glaurung is the strongest chess app available for 8-core MacPro

In general, I don't care much about how my program performs relatively to other programs, but in this particular case, I hope you are right, because it might force Mark to release Hiarcs 12 for Mac OS X.

some early results:
Match Glaurung 080430 vs. HIARCS 11.2 MP: final score 39-18-43
Match Glaurung 080430 vs. Deep Shredder 11 UCI: final score 6-2-2

That's a lot better than the last results you sent me (I've received and read all your e-mails, but haven't finished digesting them yet). Have you found some further improvements in the MP related parameters since your last e-mail? Reply by mail, please -- the discussion probably has little public interest.

Looks like the 080513 is performing stronger yet.

I don't think so. They should be practically the same; I have made very few changes in the code since 080430.

My Mac got fried somehow when I got my new computer, so I can't test it, sorry. But I do have to say that this:

To save myself from the embarassment of releasing something that doesn't work at all

is quite nice if you can do it.
