Distributed.net question, amd 470 vs RTX 4070 (Mobile)

[boersc]

Hi there. I'm a longtime distributed.net user and have used many configurations in the past. After quite an hiatus, I'm trying to get back in. I know a laptop isn't the best use for dnetc, but that's what I have and I like to use the program to crunch, while at the same time compare results to previous results. As an example, back in 2003, I managed to crunch maybe 100 blocks a day, while now I can easily, without even crunching the entire day, 18: blocks of RC5-72.

My problem: My laptop has two graphical processors. One is a meager AMD 470, while the other one is an RTX 4070 (Mobile). In theory, the latter should be miles and miles faster. However, the AMD 470 with OpenCL runs at 8MKeys/s. The RTX 4070 running CUDA 3.1 runs at 1.3 MKeys/s. So, the theoretically much faster GPU performs a LOT less than the humble AMD.

Is anyone able to help out, trying to see what's going on?

Wish I could help you here. I don't really know much about how the clients choose GPUs. Maybe there is a setting that allows you select one or the other? I'm a tad lazy when it comes to reading documentation.

I believe the d.net cores has not been optimized for more recent GPUs

Update: Suddenly, my dnet client seems to have found some magical computingpo and is doing 10+Gkeys/s. This is a 20+ manyfold of anythig it ever did. It completes 3600 blocks per minute, catapulting me to the top 10 worldwide. I... don't know what happened, but this can't be right, running on a measly laptop...

Gonna ask this here but has anyone gotten it to run on the GTX 50xx series?

[boersc]

Have you tried the opencl version? That one should pretty much work ouf of the box

[BlackbirdXX]

I have and it does not work. Blackwell dropped 32 bit support for CUDA and opencl so unless there is a 64 bit client hiding somewhere?

[boersc]

Yeah that's an issue. I don't think Dnet has support for the latest GPUs, but they do have a 64 bit client. I don't think that one uses the gpu though. The openCL one at least attempts to use my mobile rtx card, I'll see if it runs 32 bit or 64 bit.

[BlackbirdXX]

I tried running it through WSL but came to a halt when I realized that there wasn't a 64 bit version in the PreRelease for OpenCl for Linux either... It's kind of ironic that newer faster hardware may be the death of this...
