have you planned building ARMv8 apps?
because raspberry pi 3 has an ARMv8 processor

ARM:           12m49.368s
ARM+NEON:       9m56.425s
AARCH64, NEON: 13m54.945s

ARM:           20m35.665s
ARM+NEON:      15m57.060s
AARCH64, NEON: 20m52.180s

Thanks Daniel,

I will install 64 bit Windows.

And how to make such benchmarks?

Есть компьютер с 3 гигабайтами памяти, процессором Intel Pentium Dual Core E2220 и новым пустым жёстким диском.
Планируется поставить Windows 7 на него.
А какой лучше поставить?
32 или 64 разрядный?
32 или 64 разрядные оптимизированные под SSSE3 приложения RakeSearch будут считать быстрее?
Проводились ли замеры скорости счёта на одном и том же компьютере но под 32 и под 64 разрядный Windows?

I have a computer with 3 gigabytes of memory, Intel Pentium Dual Core E2220 processor and a new empty hard drive.
I planned to install Windows 7 on this computer.
What's version of Windows 7 is the best to install?
32 or 64 bit?
32 or 64 bit SSSE3-optimized RakeSearch applications will be count faster?
Whether measurements were carried out of speed of crunching on the same computer but under 32 and under 64 bit Windows?

@ Daniel

Will there be also a "AVX2 NOPEXT" v1.1 for AMD? :thumbsup:

We are still running rank 9 at this moment, correct (the 50% completion mark)? All my ODSL pairs found are rank 9.

So there is a possibility to run rank 10 search in the future?

Yes, search on space or diagonal latin squares of rank 9 is performed now. Search on space of rank 10 is also possible and interesting, but now it is a far future.

Happy crunching! :)

Thanks Daniel for the updates! Have the AVX running on a couple older machines and the AVX2 on a Ryzen. Unfortunately Panda AV flagged both exe files on all 3 machines as a virus (and deleted them) and I had to exclude them to get them to run. Never had this happen with the older versions. Is it possible to clue in the Panda people concerning this?

Hi daniel, how is about new app? cant wait.. ))
i use just AVX ,still best on win 10 with THR 2 cpu.. i experimented with coreprio last month but for boinc is not there improvement.. maybe for gamers or web. ,, i try also cinebench and other tests from hwboot but different was 100-200 points in cine. for exemple..
Thank you much for work.

I looked at the list of optimized apps, but I couldn't see the one that my computer needs, which is Linux 32-bit with SSE2.
Whereabouts on the page is it?

Can one be built for me please?

I wonder if it's possible to have the current code to run on GPUs, from what I know it should be doable: the memory requirements of the project are very low and the search is about comparing latin squares, nothing too complex.

Perhaps, but there is no news on this subject yet.

Thank you for participation!

Hi Daniel, thanks for working on this! To clarify/summarize this long thread:
What's the current status/version of the optimized app, how much faster is it than the stock version and approximately when is it due to be made default?

Repository for optimized versions: https://github.com/sirzooro/RakeSearch/releases/tag/v1.0

Any thoughts on which version is currently best for most 64bit machines?

Thanks Daniel. I grep'ed for sse2 on the Phenom, didn't think to grep for neon on the Arms.

It turns out that both the pi 2 and the pi 3 Arm processors support NEON. Both processor systems have completed units. The pi 2 and pi 3 systems have gotten credit for NEON units.
Pi zeros don't work with the accelerated apps. They error out right away. (I've turned them off.) One zero was running Jessie, and the other Stretch, but I'm sure it's the processor, not the OS.

I've verified that the AMD A8 is in fact running the AVX accelerated app, and is successful. It's about 20% slower than the Phenom II, which doesn't have AVX, and is running SSE2. It's not unusual for the A8 to run 20% faster or 20% slower than the Phenom II on different apps or benchmarks. I might try the SSE2 app on the A8. I time these by pasting 20 valid units stats into a spreadsheet, and averaging.

Stephen.
