Isaac sim 2021.1.1 crashes

im trying to launch isaac sim 2021.1.1 from the omniverse launcher.
the app window with the different choices comes up fine.
i pick “Isaac Sim” the first choice from the launcher and it crashes.

i have a geforce rtx 2070 with 16gb computer ram on ubuntu 1804

so ran it from the command line
/home/meta/.local/share/ov/pkg/isaac_sim-2021.1.1/isaac-sim.sh -v
and i get the following errors

Hi, what is your CPU specs?
Please see our system requirements for the recommended CPU.
https://docs.omniverse.nvidia.com/app_isaacsim/app_isaacsim/requirements.html

cat /proc/cpuinfo | grep “model name”
model name : Intel(R) Core™ i5-2500K CPU @ 3.30GHz
model name : Intel(R) Core™ i5-2500K CPU @ 3.30GHz
model name : Intel(R) Core™ i5-2500K CPU @ 3.30GHz
model name : Intel(R) Core™ i5-2500K CPU @ 3.30GH

It used to run last year but really slow.
i want to run multi robot simulations in a virtual factory and ultimately hardware in the loop test by connect it back to the ROS and ISAACs of the respective robots

If i go out and buy and i9 i also have to buy a motherboard, case and 64gb of ram. I hope that my scenario is not slow just for self teaching and understanding.

I was afraid i needed to buy a A6000 with 48gb of GPU ram
(The 3080s are all sold out everywhere)

i already have the geforce rtx 2070 and a 1080 ti in another machine.

could i build the inital build of a A6000 machine without the A6000 but instead link my 2 existing GPUs? will this be fast enough to be comfortable iterating over learning?

what if i just went with a i9 intel and the RTX 2070 with 32gb of ram?
is that going to be snappy enough to be worth the money? or should i just wait till i get money?

An intel 7000 series or later is recommended. The RTX 2070 with a 32GB RAM is the minimum spec for the upcoming version but may not be powerful enough to run a multi robot environment. More RAM and VRAM is recommended for this use case.

I’m afraid the 1080 Ti is not supported and may have issues running the 2070 with it.
