MySQL Cluster should be possible to run on both of these
setups. Each ndbd process is partly multi-threaded and can
utilize both processors efficiently. For larger SMP machines
we currently recommend running several ndbd processes on
the machine to better utilize the hardware. Fully multi-threaded
(like the MySQL server, mysqld) database nodes are planned for
future releases, but not in the near future.
