Question: Is there software that lets me use 3–5 computers (some with GPUs) as a shared environment to run AI agent sessions, experiments, and research?

Answer:

Yes. What you want is basically a personal AI research cluster / agent workstation orchestration layer. There are several approaches depending on whether you want:

Run agents/jobs across machines
Share GPU compute
Manage experiments
Have one “brain” controlling multiple workers

For your setup (RTX 4070 + other PCs + AI agents), I would look at these:

1. Ray — probably the closest match

Ray

Ray was built for exactly this:

multiple machines
CPU/GPU scheduling
distributed Python workloads
RL/LLM experiments
agents

Architecture:

                 Ray Head Node
              (your main machine)
                      |
        +-------------+-------------+
        |             |             |
     Worker 1      Worker 2      Worker 3
     RTX 4070      RTX GPU       CPU only

        |             |             |
     LLM agent     training     evaluation

Example:

Machine A:

ray start --head --port=6379

Machine B/C/D:

ray start \
  --address='192.168.1.10:6379'

Then Python:

import ray

ray.init()

@ray.remote(num_gpus=1)
class GPUWorker:
    def run(self):
        return "training on GPU"

worker = GPUWorker.remote()

print(ray.get(worker.run.remote()))

You can run:

multiple Claude/OpenAI/local agents
model evaluation
fine-tuning jobs
data processing

This is what many AI labs use internally.

2. Kubernetes + GPU scheduling

If you want a mini AI cloud:

                 Kubernetes
                     |
       +-------------+-------------+
       |             |             |
     PC1           PC2           PC3
   RTX4070       RTX GPU        CPU

       |
  vLLM / Ollama / Training / Agents

Stack:

Kubernetes
NVIDIA GPU Operator
KServe
vLLM
Argo Workflows

More production-like.

For 3–5 home machines, however, Kubernetes is often overkill.

3. Slurm — HPC style

Slurm Workload Manager

Classic research cluster scheduler.

Used by:

universities
supercomputing centers
AI labs

Example:

submit job

sbatch train.sh


Scheduler decides:

node1 GPU
node2 GPU
node3 CPU

Great for:

GPT training
distributed experiments
sweeps

Less good for interactive agents.

4. Docker Swarm — simple home cluster

If you want something lightweight:

docker swarm init

docker swarm join

Then:

docker service create \
 --replicas 5 \
 my-agent

Good for:

agent servers
API workers
databases

Not as good for GPU ML.

5. AI agent specific: OpenHands / SWE-agent style workers

For coding agents:

OpenHands

You can have:

Controller

 |
 +-- Agent worker 1
 |       coding task
 |
 +-- Agent worker 2
 |       test task
 |
 +-- Agent worker 3
        research task

Combine with Ray:

Ray
 |
 +-- Claude API agent
 +-- Qwen local agent
 +-- coding sandbox
 +-- evaluation worker

6. My recommended architecture for you

Given your history:

RTX 4070
trained GPT-2 locally
building CLI agents
running experiments
multiple computers

I would build:

                 Mac / Laptop
              Agent Controller
                    |
                  Ray
                    |
       +------------+------------+
       |            |            |
    Ubuntu GPU   Windows GPU   CPU box

       |            |            |
    vLLM        Ollama        data jobs

       |
   Experiment DB
       |
   MLflow/W&B

Software:

Purpose	Tool
cluster control	Ray
containers	Docker
local LLM serving	vLLM / Ollama
experiments	MLflow
dataset processing	Ray Data
agent orchestration	LangGraph / your own CLI
monitoring	Prometheus + Grafana

Minimal home version

Install Ray:

pip install ray

Head:

ray start --head

Workers:

ray start --address=<HEAD_IP>:6379

Now your 5 computers become one logical machine.

For an AI engineer building agents, I would choose:

Ray first → add MLflow → add Docker → only later Kubernetes.

It gives you 80% of an AI lab cluster with 20% of the complexity.
