Amdahl has more than 11 years experience in the development of UNIX system 
solutions. 

In fact, the next release of UTS or UTS4 (General Availability = April 1993)
is based on UNIX System Laboratories'(USL) SVR4.1 Enhanced Security(SVR4.1ES).
UTS4 is a value added 370-architecture specific SVR4.1ES that has been enhanced
to extend a standard compliant, open system operating system to the Enterprise
environment. Amdahl has added approximately 5 million lines of code to provide
value-added enhancements required by commercial, enterperise customers (in
comparison to the 2 million lines of code shipped by USL).

Some of the UTS4 value added features are MP kernel (that's right. UTS4
provides symmetric multiprocessing support for configurations up to 
eight-way processors), config(1M), migration aid tools and backup/restore 
and many more commands and features.

Amdahl's UTS Release 4 offers increased compliance to key open systems industry
standards, including: AT&T SVID, Issue 3; the IEEE POSIX Part 1(P1003.1),
System Application Program Interface(API); and, the X/OPEN Portability 
Guide, Issue 3 (XPG3), OSI(Government OSI Profile(GOSIP)), X/Windows V11R4,
OSF Motif 1.1 GUI standards, etc.

The following are some of the main features of UTS4:

.Operating System enhancements in the following areas:
	1- Virtual Memory Architecture
	2- Mapped Files
	3- Job Control
	4- STREAMS-based character I/O system
	5- Device-Kernel Interface

.File System  

UTS4 has the following filessytems: Virtual File System(VFS), Amdahl's
Extended File System(EFS), u4K (Amdahl's implementation of UNIX file system,
enhanced to use a 4K block size to match the 370-XA page size) and
ufs (BSD's fast file system).

.networking (TCP/IP, etc) 
.Real Time Processing
.User Interfaces
.Enhanced Security

Also, in the next release of UTS4(in 2 Quarter 1993)
Amdahl will provide UltraNet and 4655(i.e. VCSHost, Async terminals, OSI WAN
and BX.25), STK 4400 tape silo, X/Windows V11R5, Motif 1.2, ESCON, 6390 native,
SNMP agent, Amdahl UniTree, VCS Fiber Support for 4655 Datakit, etc. etc.
