dictionary type datastructure in cuda

Hi all,
I want to store certain values to certain keys, something like ‘dict = {{1:.090, 28:1.2, 90:0.3},{3:2.3, 45:.8, 100: 1.2,110: 3.3}, …}’ and so on. I want to implement the equivalent of list of dictionary as in python in Cuda. Please help me out

Or anything similar to that which is less expensive.

may possibly be of interest:
