GPU based algorithm on AWS Lambda

Question

I have a function which perform some mathematical operations and need a 16gb GPU system, But this function will not be triggered always and rest of time my system will not be in

Answer 1

You can't specify the runtime environment for AWS Lambda functions, so no, you can't require the presence of a GPU (in fact the physical machines AWS chooses to put into its Lambda pool will almost certainly not have one).

Your best bet would be to run the GPU-requiring function as a Batch job on a compute cluster configured to use p-type instances. The guide here might be helpful.
