Support for max_loaded_maps and num_parallel variables/parameter

It does not seem that ollama running on ipex-llm supports the most recent max_loaded_maps and num_parallel variables/parameters. Is it supported in current ollama version under llama-cpp? how does one enables it? thanks

Hi @jars101 ,

  1. Ollama does not support max_loaded_maps.
  2. You may run the command below to enable num_parallel setting: 
    export OLLAMA_NUM_PARALLEL=2
./ollama serve

Thank you @sgwhat , most recent versions of ollama do support both OLLAMA_MAX_LOADED_MAPS and OLLAMA_NUM_PARALELL for linux and windows. Running ollama through cuda(ipex-llm) does not seem to keep the settings since for every request on same model it reloads the model into memory. This behaviour on ollama for windows (standalone) does not occur.

My bad, OLLAMA_NUM_PARALELL does work but OLLAMA_MAX_LOADED_MAPS does not. I went ahead and deployed a new installation of llm-cpp+ollama and I see that now i can make use of both variables. Also, ollama ps is available as well. The only problem I see when setting OLLAMA_KEEP_ALIVE to 600 seconds for instance is the following error:

Further removing OLLAMA_KEEP_ALIVE and letting it be default of 5miunutes, im observiing the same issue.

Could you please share the output of pip list from your environment and also your GPU model? Additionally, it would be helpful for us to resolve the issue if you could provide more information from the Ollama Server side.
