30a7d7096c Bump VRAM buffer back up
Under stress scenarios we're seeing OOMs so this should help stabilize
the allocations under heavy concurrency stress.

34b9db5afc Request and model concurrency
This change adds support for multiple concurrent requests, as well as
loading multiple models by spawning multiple runners. The default
settings are currently set at 1 concurrent request per model and only 1
loaded model at a time, but these can be adjusted by setting
OLLAMA_NUM_PARALLEL and OLLAMA_MAX_LOADED_MODELS.

be330174dd Allow setting max vram for workarounds
Until we get all the memory calculations correct, this can provide
and escape valve for users to workaround out of memory crashes.

Determine max VRAM on macOS using recommendedMaxWorkingSetSize (#2354)
* read iogpu.wired_limit_mb on macOS

Fix for https://github.com/ollama/ollama/issues/1826

* improved determination of available vram on macOS

read the recommended maximal vram on macOS via Metal API

* Removed macOS-specific logging

* Remove logging from gpu_darwin.go

* release Core Foundation object

fixes a possible memory leak

7427fa1387 Fix up the CPU fallback selection
The memory changes and multi-variant change had some merge
glitches I missed.  This fixes them so we actually get the cpu llm lib
and best variant for the given system.

39928a42e8 Always dynamically load the llm server library
This switches darwin to dynamic loading, and refactors the code now that no
static linking of the library is used on any platform

d88c527be3 Build multiple CPU variants and pick the best
This reduces the built-in linux version to not use any vector extensions
which enables the resulting builds to run under Rosetta on MacOS in
Docker.  Then at runtime it checks for the actual CPU vector
extensions and loads the best CPU library available

d966b730ac Switch windows build to fully dynamic
Refactor where we store build outputs, and support a fully dynamic loading
model on windows so the base executable has no special dependencies thus
doesn't require a special PATH.

7555ea44f8 Revamp the dynamic library shim
This switches the default llama.cpp to be CPU based, and builds the GPU variants
as dynamically loaded libraries which we can select at runtime.

This also bumps the ROCm library to version 6 given 5.7 builds don't work
on the latest ROCm library that just shipped.
