Frankenstein needs help for settings
Any good soul that would give me a basic script values for latest llama.cpp to run Flash Next Q2_XXL on my Frankenstein Linux PC with 3 GPUs 24GB + 12 GB + 8GB VRAM and 64GB of RAM? With or without ngram on nvme.
I am running 3.8 27B Q8_0 with BF16 KV cache flawlessly, no luck to even load Flash Next. Who knows maybe Q2 is not worth it vs 27B Q8?
Don't know if this helps, but if you just want to test it - with today's update a UD-IQ4_XS quant loads nicely for me in Unsloth Studio on Linux. I also have a multi GPU setup: 32GB + 24GB VRAM and 64GB RAM.
I set a 50k context and managed to get around 30 tokens/s.
Thank You.
Last night I installed Unsloth Studio, but it randomly freeze even without model loaded. I will try again.
Random freeze again. Updated to 804 Beta.
Does anyone has simple parameters for the script to run it on plain llama.cpp
Plain llama.cpp does not support this model yet, you have to compile it manually by pulling in this PR: https://github.com/ggml-org/llama.cpp/pull/27742
