with a SCSI layer, can
take many seconds. Once you detect a disk it takes a bunch of slow seeks
to read the partition table and mount a modern file system (not EXT2).
So trimming the system initialization time further isn't a priority until
after the file system and IB init times are
k jobs), rather than re-think the need for running them at
all. IIRC, it was companies such as Octiga Bay that actually implemented
global-clock gang scheduling of system daemons, again with a network that
implemented global synchronization operations.

won't obviously break when we have 64 cores in each of 4

That's true for the "strip down a distribution" approach. You have to
repeat the work for each new release. And test it, since an
updated release might change to rely up
traffic, the whole cluster-wide app stops.
Next posting: how the app itself can be the cause of slow-downs, and why
cluster-specific nameservices and why library/executable memory
"wire-downs" solve problems.

The goal of clustering is to create a unified system out of independent
pieces -- creating the illusion of a single system. The more you have to

systems as needed for application data, not for the underlying system.)
