Hi Peter,
Using Alaric UCI and setting hash size to 96 MB I get a memory allocation of 162 MB! Setting 128 MB I get 194 MB allocation (right in the sense that it is 32 MB bigger).
Using Alaric WB and setting hash to 96 I get an incredible 258 MB memory allocation. Setting 128 MB the allocated memory is 322 MB!! This is 64 MB bigger than that with 96 MB setting.
I tried the UCI version under both the Arena 1.99beta4 and Shredder 9 GUI's.
Further value pairs of hash and allocation for the UCI version:
16 - 82
24 - 90
32 - 98
48 - 114
Up to now, normal increase, but too big 'offset'.
64 - 66 (??)
65 - 131
Best regards,
