Max number of parallel envs in Isaac Sim

Hi, recently I tested OmniIsaacGymEnvs on my RTX 3090 with 24 GB memory. I tried to run the random action script with 8192 parallel environments, but it popped an out-of-memory error.

I am wondering about the maximum number of parallel envs we can use in Isaac Sim, as I know that we can use even more than 30,000 envs in Isaac Gym.


Hi there, Isaac Sim is expected to take up larger memory than standalone gym, the exact amount of memory depends on the scene you are running and on the number/type of robots/meshes in the scene. Note that this applies to both GPU and CPU memory. Please checkout the Memory Consumption section in our docs for an example: OmniIsaacGymEnvs/ at main · NVIDIA-Omniverse/OmniIsaacGymEnvs · GitHub
