Simulation and meshing jobs are run on dedicated [AWS instances](https://aws.amazon.com/ec2/instance-types/) and SimScale automatically determines the amount of CPU cores, main memory, GPUs, and GPU memory that is required to run your simulations successfully and efficiently. SimScale has instances available with up to 755GB of memory for the largest of simulation jobs.
