Hiarcs retains hashtable info between moves for future reference. In Engine v. Engine in Fritx 5.32 (probably also in Hiarcs 7.32) I assume after Hirac's move RAM (hashtable)is cleaned by Fritz for its move. In playing around with various hashtable settings and time controls its fairly easy to get Fritz to fill hashtables frequently (I have 64MB Ram on Pent II @ 266). When that happens Fritz (apparently) goes to Win 98 dynamic swap file on hard drive as hard drive lights up and makes "writing, accessing" noises. After Fritz moves, Hiarc never accesses hard drive for its move. This leads me to believe that Hiarcs "saved" hashtable on its previous move has been deleted from RAM, and was never stored on the hard drive, so Hiarcs must start from scratch. Right? (for my tests I use same hashtable size for both engines, varies from 16- 25MB, higher values freeze fritz while, apparently, fritz cleans the swap file? and wastes valuable time, running its clock down) It seems this could also be a problem in, say, correspondence analysis mode if you are multi-tasking, using RAM in other applications. Question is, where does Hiarcs save the hashtable info after its move and can the "saved" info be easily deleted as described above. If so then a major feature of Hiarcs 7.32 can be easily compromised. Thanks, Regards, Chris
