Operating systems work as part of the NYU Ultracomputer Project is currently
focused on design and implementation of a new UNIX system for highly-parallel
shared-memory MIMD computers.  This new system, known as symunix 2, includes
the following features:
	- avoidance of serial bottlenecks due to critical sections.
	- efficient support for applications with highly-volatile
	  fine-grained parallelism.
	- support for very low overhead inter-process synchronization
	  and communication via shared memory.
	- a new virtual memory system with powerful and flexible support
	  for memory sharing, high-performance I/O, debugging, and
	  checkpoint/restart.
as well as others.
