LOAD DATA FROM DATABASE WITH CUDA

Dear all,
I am new to GPU computing and CUDA. As a part of my project i have been given a task to find duplicate entities in a large database with cuda programming. How to load the data in the database to GPU device with CUDA. I have surfed internet but unable to find any references.

Any little suggestion will help me a lot.

Thanks in Advance

The data from the database will first have to be load into cpu/main ram.

Then the data must be transferred to gpu/ram and then the cuda kernel can be executed on it.
