Proper values for watermarks?

[yulistic]

What are the proper values of the WATERMARKs in Memtis?

#define MIN_WATERMARK_LOWER_LIMIT   128 * 100 // 50MB
#define MIN_WATERMARK_UPPER_LIMIT   2560 * 100 // 1000MB
#define MAX_WATERMARK_LOWER_LIMIT   256 * 100 // 100MB
#define MAX_WATERMARK_UPPER_LIMIT   3840 * 100 // 1500MB

#define MIN_WATERMARK_LOWER_LIMIT 128 * 100 // 50MB

We may use 1/10 of the original values. For example, RSS of our Liblinear benchmark is 1/10 of that of the Memtis' experimental setup.

For the MIN_WATERMARK 3% of the DRAM (top-tier) capacity is used and For the MAX_WATERMARK, 2% is used.

max_nr_pages = max_nr_pages * 2 / 100; // 2%
