Support for all except the latter was dropped back in 2014, leaving only the F8 based DL740 and DL760 G2 machines in this catery, with up to eight single-core Socket-603 Xeon-MP processors with hyperthreading. Like the already removed machines, the HP F8 servers at the time cost upwards of $100k in typical configurations, but were quickly obsoleted by their 64-bit Socket-604 cousins and the AMD Opteron. Earlier servers with up to 8 Pentium Pro or Xeon processors remain fully supported as they had no hyperthreading. Similarly, the more common 4-socket Xeon-MP machines with hyperthreading using Intel or ServerWorks chipsets continue to work without this, and all the multi-core Xeon processors also run 64-bit kernels. While the "bigsmp" support can also be used to run on later 64-bit machines (including VM guests), it seems best to discourage that and get any remaining users to update their kernels to 64-bit builds on these. As a side-effect of this, there is also no more need to support NUMA configurations on 32-bit x86, as all true 32-bit NUMA platforms are already gone.
