These are approximately the top 8 actively developed engines with Houdini and Gull thrown in as gatekeepers/benchmarks. SF-YBW representative included as well.
Nice result for the latest Andscacs so far.

Start all threads searching on root position and
use only the shared TT table as synching scheme.
It seems this scheme scales better than YBWC for
high number of threads.
