2.6 Why keep CPU: GPU ratio of 1:1 in R940xa? Query Performance with respect to IO bandwidth [Source: MapD] As shown in Figure 4 above, query performance increases as the data is moved closer to the compute layer. Database acceleration is not achieved if data is fetched from disk (SSD) because of IO bottlenecks. Since GPUs improve performance only when data is available in main memory, any database architecture using GPUs for acceleration should also use CPU in-memory technology.

Why keep CPU: GPU ratio of 1:1 in R940xa?
Query Performance with respect to IO bandwidth [Source: MapD]
As shown in Figure 4 above, query performance increases as the data is moved closer to the compute layer.
Database acceleration is not achieved if data is fetched from disk (SSD) because of IO bottlenecks. Since
GPUs improve performance only when data is available in main memory, any database architecture using
GPUs for acceleration should also use CPU in-memory technology.
