Should be able to work on 4GB GPU too

What are technical problems to make this GPU accelerated proving work on 4GB card?
It will be nice for developers to try out things on low end GPUs.

it's tradeoff. we have optimized memory usage.
We have to save temp data somewhere to avoid data copy, because the data copy from disc or memory to GPU need a lot time.

The minimum requirement is 10G, recommended 12G.

Is it possible to control how many kernels will be launched? And based on that help make it work on low end GPU ?

This is not the direction we are working on.
Currently only one GPU is used, Out next goal would be multiple GPU in parallel if we got funded.

FYI, Memory usage depends on your circuit. you can use a small circuit for the development.
