The question I have is whether or not the contents of >the hash table used by Shredder would then be used by Fritz. The first thought >would be that switching engines would erase the Shredder hash table(s) and set >up new empty Fritz hash table(s). But does it have to be that way? The hash table is part of the program's memory address space. Each program has it's own address space. There is no sharing of this space between chess engines. Most modern operating systems take care that one address space does not access another program's address space, as this would defeat the goals of system stability and program reliability in spectacular ways.
