I have made some improvements to the cpu code. I am seeing somewhere between 30% and 40% speedup, depending on the case.

I have deployed the new executable for 64bit linux. I am currently trying to get it to build for 64bit windows. I hope to have that ready by tomorrow sometime.

The next step is to use these same tricks on the GPU versions. GPUs can be very finicky, so this might take several weeks before I have something worthwhile.

Sounds good. Please you are having some success in speeding things up for science.

Good news! Thank you for your work and your dedication to make the applications evolve.

That's impressive. Looking forward to try out the new app version soon!

Yes, we should overcome somehow that 20 million tasks search.

The 64 bit Windows version has been deployed.

Now moving on to GPUs...

Will you be able to create a new faster app version for 32-bit Linux, for those of us still using older hardware?

Unfortunately, the tricks I used took advantage of 64 bit registers. There is no way to do the same thing for 32 bit machines.

Now moving on to GPUs...

Out of curiosity are you planning on releasing a improved GPU app before we start search 16×271? I have read your latest post in batch plan. I thought it was more appropriate to ask the question here.
Edit= changed the number 13 to 16 for the search

I will if it's ready in time. Other things came up so I lost several weeks in there, but am now back to improving the GPU app.

Thanks for the update. All the best making improvements

Hi. Es, gibt, für NVidia Geforce GPU's, einen, Neuen Treiber, für Windows 10 x64. :-)



Auf, www.nvidia.de . Gibt, es, die Version 460.79 notebook win10 64bit , zum herunterladen. :-)



Und, damit, einen, Neuen, Treiber, zu installieren, und damit, ihn zu aktualisieren. :-)



Boinc, zuvor, Schlie0en, Treiber Updaten, Boinc Starten, und Benchmark durchführen. :-)



MfG

I just released the new app version for Linux Nvidia Cuda.

I tested it on 100 WUs and it averaged about 33% faster over the previous Cuda version.

I am now making these same improvements to the openCL versions. If all goes well, I should have new apps for Windows and AMD cards within a week.

Hit a snag on host 2248192

/lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.29' not found (required by [cuda 30 app])

Investigating.

Seems I've got

GNU C Library (Ubuntu GLIBC 2.27-3ubuntu1.3) stable release version 2.27.

and it seems the free-standing downloads of 2.29 are no longer available. May try upgrading from Mint 'Tessa' 19.1 to Mint 'Mate' 20 ???

Same for me on an older system that still GLIBC on 2.28. It would be time to update

Sorry guys. I used a newer version of Cuda which apparently requires glibc 2.29. Not sure what else I can do on my end.

Glibc for me too. You really ought to compile on the oldest Linux you can find. Ubuntu LTS 16.04 or Debian or something.

Going to leave it for tonight. I've converted the GPU tasks back to run on the CPU, so they won't be wasted or need to be resent. I'll have another look at upgrading in daylight tomorrow, now I know what I'm looking for.

I don't think it's the version of Linux I build on. My version of Glibc is 2.31 but the executable still comes out 2.29. Sounds like there's something going on in my makefile, possibly related to the Cuda compiler nvcc. When I get a chance I will look into it.

After what feels like a very long day (the promised 'upgrade in place' tool appears not to exist), host 2248192 now reports itself as "Linux Mint 20". That claims to include 'Ubuntu GLIBC 2.31', but it's evidently backwards compatible - both GTX 1660 SUPER cards are now happily crunching with the new app.

I should have mentioned, I am going to rebuild inside a VM with an older linux version in order to get around this problem. If you had known this in advance, you could have skipped the troublesome upgrade process, so I apologize for that.

Anyways, other users now know that a fix is on the way. I hope to have the newer version built by sometime tomorrow.

I should also mention, the app is now using a lookup table to set some gpu parameters dynamically. The settings for the 1660 were based on my card. But I've been wondering if there might be other system parameters that affect performance such as RAM, CPU, or PCI-express version. I guess time will tell. If you want to play with the lookup table, it should be in the project subdirectory with the executable.
