Compute Intensive VM

[drzakir]

Hi,
I have 3x Hosts (each has CPU=Dual 2.1 Ghz, 16 Cores, RAM=64 GB, GPU= Nvidia RTX A2000, NIC= 1G Dual Ports).

Now I want to create a single VM that wants to use all the compute resources i.e, CPU, RAM and GPU of all 3x Hosts, (means a single VM with 2.1 Ghz dual CPU of 48 Cores, 192 GB RAM and 3 GPUs). Is it possible in Proxmox?

This is not possible with any known virtualization system.

No. As already said.

A single VM can use (nearly) all resources of one host - the host it is running on.

A process running on one computer can not run on different computers at the same time. Never. (Actually there may be special ways to achieve this in critical technical systems like the Mars Rover...)

If your goal is to utilize the compute power of a cluster for a single program to solve a specific problem, you need to dissect the problem, parallelize it and distribute it. This is the way a HPC - a High Performance Cluster - works. This is NOT the kind of concept PVE is implementing.
