Is it possible to add flags for setting the smaller bloom filter to use MIC ram (7200 MT/s) for people using Xeon Phi hardware? These systems have about 14GB of on chip memory, which is somewhere around 2.5-3.5 times faster than the DIMM memory on the system.

You would need to use numactl to enable it, and the processor in SNC2/SNC4 mode

Of the 16GB of ram present on chip, typically about 14GB is available for running a program.

I'd like to make a patch to do this, but my C/C++ skills are lacking.

How do the three different bloom filters relate to each other?

Thank you in advance.
