Subject: A thought about using huge physical memory for chess engine

I have seen that in CCT6 Crafty used only 386 MB for hash table on a machine
with 8 GB physical memory. It means that a huge memory (at least 7 GB) is almost
redundant. I think in coming time, the situation will be worse: more physical
memory could not be used for chess engines. I have been thinking some ways of
using large size of memory and here may be one: load all 3-4 EGTBs into memory
(near enough - need little more memory or some selections of EGTBs). Thus,
instead of searching on HDD, we can search on memory. Some good programs (like
Crafty) can develop some methods to look up EGTBs not only in main search but in
qsearch.

Just my two cents. :)
What do you comment?
