Alenka is a modern analytical database engine written to take advantage of vector based processing and high bandwidth of modern GPUs.
Features include:

Vector-based processing
CUDA programming model allows a single operation to be applied to an entire set of data at once.
  
Self optimizing compression
Ultra fast compression and decompression performed directly inside GPU
  
Column-based storage 
Minimize disk I/O by only accessing the relevant data
  
Support for zone maps. All columns have indexes allowing for better performance.
