Cuda Plotter Crashes During P1 #9

Closed THESHULK closed 1 year ago

THESHULK commented 1 year ago

I'm having trouble getting the k32 cuda plotter working. As you can see from the command output below, it stops plotting after P1 Table 2 without any indication as to why. Is there a log file somewhere I can look at? I'm hoping this is simply user error. I've tried various memory levels to no avail. My E: drive is an M.2 NVMe 1TB drive and the F: drive is a 14TB HDD.

Here are my system specs:

That CPU is PCIe 3 only, so 3080 is mostly going to sit idle. 3060 ti is the cutoff for PCIe 3, I think.

Don't you need 128 GB RAM to use cuda plotter?

From what I understand, I can still plot with the 3080 Ti but I don't get any added benefits over a 3060 Ti. As for the RAM, according to this table k32 with compression level 1 the RAM is not applicable? I'm not sure what that means though.

EDIT: I just realized that table is referencing farming not plotting.

Jacek-ghub commented 1 year ago

If you have a spare 3080, by all means, it will work great. Not sure, but may have some power saving, as it will be underutilized.

Yup, exactly that is the farming table. Here is the readme for cuda plotter - https://github.com/madMAx43v3r/chia-gigahorse/tree/master/cuda-plotter

So, this one applies to plotting - "or partially in RAM with 128G."

THESHULK commented 1 year ago

Ah thank you. It's working with k29. Plots are generating in under a minute. Hopefully they're valid.

Jacek-ghub commented 1 year ago

Sorry, I was thinking about k32 plots.

No, k29 are no good. Only used to for testing.

If you plot for Chia, you need k32. If for MMX, the minimum is k30. (Yeah, from your logs, looks like Chia, so k32 it is.)

THESHULK commented 1 year ago

I see, well that's a bummer. So I need a minimum of 128GB RAM so I can plot k32. And once I create the plots, I have to farm them with the gigahorse node, right?

madMAx43v3r commented 1 year ago

yes

THESHULK commented 1 year ago

Thanks so much!

However, you can open an enhancement ticket asking for 64 GB RAM for k32 plots, and have your buddies support you on that. ;) There is a lot of chat about that as most farmers don't run server grade boxes.
