Cyclone 3.4: a warning!

[Jouni]

Please note, that default is dynamic hash. So when I run long analysis/test suites Cyclone used only small hash optimized for 5s play!
In analysis engine should automatically use all available hash.

Use your GUIs UCI options...

In Arena:
Choose:
Engines
Engine 1 Cyclone 3.4 -> Configure

uncheck the 'Dynamic Hash' checkbox...
set 'Hash' 'to the desired size (for ex: 512 or 1024)
or
leave 'Dynamic Hash' checkbox enabled and set 'Nodes per Second' and 'Seconds per Move' to whatever settings are appropriate...
for example, changing 'Seconds per Move' to 300 (5 minutes) will also increase the Hash size...

there's more info here:
