Thank you for report!

I recently got a new pi 3, and couldn't recall how to install the app. Google got me to my own instructions here. I had forgotten the restart. I now have the instructions local. Apparently, i use the neon version on pi 2 and pi 3.

My notes suggest that the neon version may be 10% faster than the other one on the pi 3. That's within experimental error.

I don't have a comparison on the pi 2. I only have neon times.

I don't have a comparison on the pi 2. I only have neon times. Weird. I also started routinely overclocking the pi 2 about then.
The overclocked pi 2 shows 23% faster than the pi 3. Also weird.

Stephen.

just a quick question.
i am explaining the installation of this app to a few other people, and i found out, the standart poinc path in windows changed.
maybe you could change this

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?

Hi,
I am working on new version of my optimized app. I am going to release it before end of January. I will add 32-bit Linux versions together with other ones.

I'm curious to hear more about that and once it's ready benchmark it! Keep up the good job!

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.

Things looks good, most things are ready now. If everything will go well, I will release new version this week.

Hi all,
I have (finally!) released new version of my optimized RakeSearch app, Opti v1.1. It can be downloaded from here: https://github.com/sirzooro/RakeSearch/releases/tag/v1.1. Installation instruction is the same as before, so please refer to 1st post in this thread for details.

There are 4 versions available as before: SSE2, AVX, AVX2 and AVX512. There are also apps for 32-bit Windows and Linux.

For comparison, here are results for previous (Opti v1.0) version:

SSE2:
real    6m2.431s
user    6m0.451s
sys     0m0.030s

AVX:
real    5m45.740s
user    5m43.759s
sys     0m0.026s

AVX2:
real    5m24.624s
user    5m22.626s
sys     0m0.042s

And this is for new version:

SSE2:
real    4m14.850s
user    4m12.858s
sys     0m0.047s

AVX:
real    3m58.809s
user    3m56.813s
sys     0m0.035s

AVX2:
real    3m51.881s
user    3m49.885s
sys     0m0.040s

As you can see, new app version is about 30% faster than previous one.

New AVX2 app does not use PEXT instruction. This means that this app version also on AMD Ryzen and Threadripper will be faster than AVX one.

I also changed AVX512 app version a bit, now it uses new instructions which operate on old (SSE/AVX) registers only. This means that it will not suffer from CPU frequency throttling related to use of new AVX512 registers. I have some results captured for his app version. Unfortunately this machine had other things running on it, so results look high in comparison to ones above. Anyway, you can see that AVX512 app is the fastest:

SSE2:
real    6m47,701s
user    0m0,000s
sys     0m0,046s

AVX:
real    6m22,165s
user    0m0,015s
sys     0m0,062s

AVX2:
real    6m14,271s
user    0m0,000s
sys     0m0,031s

AVX512:
real    6m12,458s
user    0m0,000s
sys     0m0,062s

I did not create ARM/AARCH64 app versions yet, I am going to release them soon.

Thank you very much, Daniel! It is a pleasure to see your interest in the project, and we appreciate how much effort you are contributing.

Thanks Daniel! Great job.

Yea great work Daniel thanks again :)

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?

Hmm, interesting. I tried to scan them using Virus Total which allows ts scan file using 69 scanners (including Panda) and they are clear. MetaDefender (37 scanners) also confirmed this. Anyway, I sent info to Panda about this false positive.

Thanks Daniel for your efforts in getting this out there.

However I seem to have a problem with your new programme, all I get is

<core_client_version>7.4.25</core_client_version>

Which is trashing a heap of work units, I re-downloaded and re-installed the files but this made no difference.
I noticed that the line <platform>xxxx</platform> had been added to the apt_info.xml file so I removed that to see if it made a difference but alas it did not.
So I will re-install your older version and see if all starts working again.

Thanks
Conan

Which app was used? The 955 doesn't have AVX so the SSE app would be required.

Same exe name so these should be a drop in replacement.

Thanks for the great work Daniel.
