because in that section of the article thomas was talking about SMT (symmetric multi-threading), something the e6500 core architecture supports. the e5500 is not SMT-capable.


Well the topic was SMP, but yes it trailed of into SMT which is an entirely different thing.

The e6500 cored products are the first to offer SMT, which is easier to digest if you think of it as what Intel refers to it as - hyperthreading.

@iggy

But they can't call it hyperthreading, because that's the name for one POSSIBLE implementation of SMT. Besides, having SMP without optimising for SMT when the CPU lineup has SMT would seem to be not very ambitious

Besides, freescale claim to have a lot more redundancy in their SMT than Intel, Intel had 15-30% benefit from HT back in P4 era (mostly from avoiding pipeline stalls), using passmark numbers I would say they have 40-60% now (I'm interested in reading more about additional added redundancy of computing blocks if anyone has a link). Example:

i7-4930, 6 cores, 12 threads, 3.4GHz (3.9GHz turbo). Scaling single thread performance of 1998 down by turbo frequency to normal frequency ratio, scaling up from 1 to 12 threads, dividing by actual 12 thread passmark rating:
((1998*34/39)*12)/13077 = 1.59 and a bit.

Haven't seen any single thread vs SMT performance numbers for freescales e6500 (you woulda thunk someone was eager to run some numbers by now), but datasheets claim gain from 3.3 to 6, a ratio of 1.81.

It was in fact another enlightening article. Thanks.

AFAIK the turbo frequency is used only for some, few (sometimes only one), cores. So you cannot scale the results by 3.9Ghz.

Thanks for posting. We missed another post about DCFS and LNFS (with link to OS4 wiki).

I think even the X1000 benefits from new GCC, it's not strange, things get optimized improved, we that are making programs for AmigaOS4.1 has hoped for updated SDK some time now, this might be good excuse to compile a new MPlayer.

It looks like GCC 7.1 is the latest official version. I wonder what is the reason that Hyperion targets 5.4? Stability?

By the way, simplegit (sgit) would be a nice contribution for the SDK.

How else you want to build optimized binaries?

@Mr_Capehill

I think there is requirement for C++11, CLIBS in newer GCC's, or something like that means we need to get new CLIBS.

anyway I'm sure it takes time to adapt GCC for AmigaOS, paths and so on is different on AmigaOS. So keeping up with the latest versions might not be so easy.

You'd hope they wouldn't be necessary, but then X64 software vendors optimize for differences between AMD and Intel cpus.
Of course, THEY release one package that installs appropriate binaries for whatever tweaks are needed.

Why we aren't thinking along those lines baffles me.

@iggy

It's lot work compiling different versions of program for different CPU's, most the time there is nothing to gain, but then there a CPU AltiVec, and so there might idea write some AltiVec code, but anyway it a lot of work.

Need?

No, it is not a special SPE version, but ffmpeg uses mostly fixedpoint, so in the current AmigaOS 4.1 state, the tabor is about 60% faster as sam 460 in decoding.

Neither Tabor nor the X5000 need dedicated binaries. However, it is useul to have a compiler that can use CPU-specific features, or optimise for specific CPUs. For example, it's definitely useful to be able to compile code that uses Tabor's unusual FPU.

it was clear to start with that tabor needs dedicated binaries to perform respectively, i was wondering about x5k, as yiu see.

Probably just because of limited Sebastian's time (as i see from adtools repo, he works on it alone most o time), and because 5.4 was a least a bit tested before (by yam, mui, and some other stuff).

Through, if i remember right, there was some issues as well. As far as i remember, Hans with radeonhd (or it was w3dnova?) have issues back in time, and was in needs to switch back to 4.x one. Also zzd10h had to recompile some of his tools via 4.x, as 5.x (at time when it was tested) give some problems. I not sure there through, just as far as i remember. Maybe that all deal with already in adtools.
