|Description:||An experimental variant of the standard
This MPM is experimental, so it may or may not work as expected.
This is an experimental variant of the standard
worker MPM. It uses a Leader/Followers design pattern
to coordinate work among threads. For more info, see http://deuce.doc.wustl.edu/doc/pspdfs/lf.pdf.
This MPM depends on APR's atomic compare-and-swap operations for
thread synchronization. If you are compiling for an x86 target
and you don't need to support 386s, or you are compiling for a
SPARC and you don't need to run on pre-UltraSPARC chips, add
--enable-nonportable-atomics=yes to the
configure script's arguments. This will cause
APR to implement atomic operations
using efficient opcodes not available in older CPUs.
