Concurrent Communicating Kernels in CUDA?

Lets say I have a device with 2880 cuda cores.

I want to run a Monte Carlo simulation where:

• 2000 threads are each running a sample
• 880 threads are generating random numbers

This is because:

• I only want 2000 samples therefore the other 880 would be sitting idle
• I know that generating random numbers can be slow

Therefore I want to make a pool of random numbers that is replenished continuously by the 880 threads which the 2000 sample threads can take when required.
