IBM RT (TM) SYSTEM NEW MODELS
IBM Announcement Letter Number 188-120 dated July 19, 1988
IBM US - Last Revised on July 19, 1988
Brief Description of Announcement, Charges, and Availability
The IBM RT system family has been expanded to include three
new high-performance models of RT systems: Models 130, 135 and B35.
These models feature increased processor cycle speed and include an
enhanced CMOS RISC processor card, an enhanced level of the Advanced
Floating Point Accelerator and 114Mb of fixed disk storage. All new
models come standard with 16Mb memory on the new processor card.
These models offer increased performance over the previously
available IBM RT systems in the AIX (TM) workstation family of
products. They are particularly attractive for the demanding
engineering/scientific and technical/professional application
environment. The new models support the majority of features
announced for the 100 series of RT models. (Refer to Product
Announcements 186-006, dated January 21, 1986, and 187-021, dated
February 17, 1987.)

HIGHLIGHTS
o Three models featuring a CMOS RISC processor and memory chips
o Enhanced level of the IBM Advanced Floating Point Accelerator as
standard
o Standard 16Mb of fast memory on Models 130/135/B35
o Standard 114Mb Extended ESDI Fixed Disk and Adapter
o Selectable option to upgrade to a 310Mb fixed disk installed in
first drive position (additional charge)
o Two additional drives may be installed on Models 135/B35 for a
total of 930Mb of internal storage
DESCRIPTION
The IBM RT family of products is being expanded with the
addition of Models 130/135 and B35. These new models come equipped
with a CMOS RISC processor on the advanced processor card. The new
Models 130/135/B35 have 16Mb of memory in their base configuration.
Also included as standard features are an enhanced level of the
Advanced Floating Point Accelerator (designed to operate with the
enhanced processor card), an Extended ESDI Magnetic Media Adapter,
114Mb Extended ESDI Fixed Disk Drive, and 1.2Mb diskette drive.
Models 135 and B35 are floor standing system units and can
accommodate two additional fixed disk drives (70, 114, or 310Mb) as
well as a second 1.2Mb diskette drive. Model 130 is a desktop system
similar to the Model 115.
The three new models are functionally compatible with the
existing 6150/51 Models 115/125, and B25. Compatibility is also
provided (at the level of the virtual machine interface and above)
with the other models of the RT system. Performance is substantially
improved when running the same IBM programming and configured with
the same IBM feature and peripherals.
NOTE: Recompiling of programs may be necessary to achieve maximum
performance of the new models.
TECHNOLOGY
The RT Models 130/135 and B35 belong to the new series of RT system
products announced February 17, 1987. Technology and architecture
are similar to the Models 115, 125, and B25, but differ in that
processor cycle speed has been increased. In addition, logic and
architecture have been modified to synchronize the faster processor
with other system components (for example, Advanced Floating Point
Accelerator) in order to maximize overall performance. (Refer to the
Technology, Performance and Configuration sections of Product
Announcement 187-021, dated February 17, 1987, for a more complete
discussion.)
PERFORMANCE
Today's announcement focuses on greater performance. The
improvements include a faster processor and faster floating point
performance. The new RT models being announced bring the RT system
to a measurably higher performance level.
The RT advanced processor has a reduced cycle time and
executes up to 5.6 million instructions per second (MIPS), depending
upon the actual instruction mix. Specifically, a configuration
consisting of an IBM RT System Model 135 (which includes the Enhanced
Advanced Processor Card, the Enhanced Version of the the Advanced
Floating Point Adapter) and AIX/RT Operating System Version 2.2,
produced the results indicated below on the industry standard
Whetstone and LINPACK FORTRAN benchmarks. No other jobs were
processing while the performance benchmarks were running.
o Floating-Point FORTRAN benchmarks
- Whetstones (double precision) -- 2020 KWIPS
- Linpack (double precision) -- 410/780* KFLOPS
* NOTE: AIX/RT Version 2.2 supports improved performance in solving
a system of linear equations. The LINPACK benchmark in double
precision using Coded Basic Linear Algebra Subprograms (coded BLAS)
and the FORTRAN 77 compiler, was executed on an RT System Model
135/B35 with Enhanced Advanced Processor and Enhanced Version of the
Advanced Floating-Point accelerator card installed, performs at .780
million floating-point operations per second (MFLOPS). This increase
in performance is accomplished through enhancements to AIX/RT
Operating System Version 2.2, consisting of Assembler language
subroutines that execute via Advanced Floating Point microcode.
Floating point microcode enhancements contribute to some of
the performance improvements. Although the microcode enhancements
are not licensed programming, for customer convenience they are
shipped with the VRM portion of the AIX/RT Operating System Version
2.2. The Floating Point assembler language subroutines are shipped
with the AIX/RT 2.2 operating system. User programming is required
to achieve the maximum performance improvement. Documented
instructions and examples of how to use the Assembler routines are
provided in the RT PC Hardware Technical Reference Manual, Advanced
Floating Point section.
Performance in fixed point operations has also been improved.
An IBM RT configuration consisting of an IBM RT Model 135, or B35,
AIX/RT Operating System Version 2.2 and Advanced C Compiler produced
the results indicated on the industry standard Dhrystone Version 1.1
fixed point benchmark. No other jobs were being processed while the
performance benchmarks were running.
o Fixed-Point benchmark -- using the Advanced C Compiler
- Dhrystones 10400
NOTE: These benchmarks are sensitive to the types of compiler
optimizations performed. For the results shown, these optimizations
include:
o In-line subroutine expansion
o Code motioning
o Constant folding
o Straightening
o Commutation
o Short circuiting.
Overall system and programming performance are subject to a
number of other variables, and accordingly, the foregoing parameters
are not necessarily representative of either overall system or
programming performance.
