I am trying to use MPI but each node uses the full RAM. Is this how MPI is supposed to work? I didn't think it was. Here's the details.

I am on commit 1cbf561. I modified the Makefile so I could compile it like this (see #2208).

LLAMA_MPI=1 LLAMA_METAL=1 make CC=/opt/homebrew/bin/mpicc CXX=/opt/homebrew/bin/mpicxx

I run the following.

mpirun -hostfile hostfile -n 3 ./main -m airoboros-65B-gpt4-1.2.ggmlv3.q4_0.bin -n 128 -p "Q. What is the capital of Germany? A. Berlin. Q. What is the capital of France? A."

This is the output. It works, but each node uses 39 GB of RAM. Each node has 16 GB of RAM, so they swap bad.

I'm guessing it fails because it runs out of memory.

Can you try updating to latest master since 32c5411 was an mmap regression

Also, maybe try using mlock argument - again, I'm just giving random ideas without really having a good understanding if this makes sense

Not sure about 65B, but I tried a 33B model that mmaps 26GB on a Mac mini with 24GB RAM. It swapped and worked at 46 seconds per token. Then I added a second Mac mini over MPI and together they worked at 450ms per token, which is 100x faster.

Yup, the approach is definitely viable. There is more progress here: #2164 (comment)

On Mac mini, you can also enable Metal which might lead to some extra improvements
