Improve Performance with Multiprocessors
Today's
multiprocessor computers offer superior performance on mainframe
platforms. The challenge is to use that computing power to
its ultimate advantage. MP/204 from Computer Corporation of
America (CCA) meets the challenge.
MP/204
enables a single copy of Model 204 to leverage multiprocessing
configurations on System z Processors running z/OS. The result
— significant performance enhancements in both system
throughput and response times by utilizing parallel CPU processing.
MP/204
can provide performance benefits in the following situations:
 |
Performance is suffering due to high CPU utilization, particularly from CPU intensive operations such as complex processing, large sorts, computation, and analysis |
|
You are experiencing significant transaction growth in online environments |
|
New applications are being added to an existing online system |
|
You have major batch requirements, yet batch windows are shrinking and now overlap with the online scheduler |
MP/204
is the answer. It delivers instant scalability to Model 204
applications by optimizing the use of your existing multiprocessor
hardware to provide an immediate capacity boost.
Since
you do not have to change a line of code to gain the advantages
of MP/204, you protect and leverage your investment in existing
applications.
The Power Within
The advantages
of MP/204 flow from the power within. It provides an immediate
and automatic capacity and performance boost in multiprocessor
environments.
Without
any programmer or user intervention, MP/204 automatically
offloads FIND statements and IFFIND IFAM functions, portions
of sort processing for medium to large sorts, loops and subroutines
that do not contain certain update statements, and any $functions
that allow parallel processing. MP/204 has proven its performance
benefits at sites running up to four parallel processors.
New System Monitoring Statistics
Along
with a boost to performance and capacity, MP/204 gives you
the tools you need to monitor your system so you can avert
problems before they happen.
Included
are new system statistics showing CPU utilization per task,
scheduler overhead, rate of task switching, WAIT and POST
macro statistics, and multi-processor lock contention.
All of
this new statistical information is written to the journal
dataset and can be queried using existing tools.
MP/204 Commands and Statements
MP/204 also adds commands to monitor tasks and associated offload
levels, User Language statements that dictate constructs to
be off-loaded, and User Language statements that help identify
code that cannot be offloaded. Also, you can use MP/204 User
Parameters to specify the number of subtasks attached at initialization,
the number of active subtasks at any point in time, and response
time versus overhead trade-offs in the scheduler. With MP/204,
you can dynamically configure/reconfigure the subtask configuration.
V7R1 Enhancements
Prior to the release of Model 204 V7R1 in March 2009, MP/204 customers
could achieve symmetric multi-processor utilization of up
to 650 percent. But some customers were forecasting growth
rates that would challenge even this amount of raw processing
power. Consequently, Model 204 V7R1 includes an extensively
re-engineered version of MP/204 that further increases the
multi-processing capabilities of Model 204 up to 850 percent,
thereby allowing a single copy of Model 204 to use up to 8,000
MIPS when running on a large System z10.
System Requirements:
|
Model 204 Version 6 Release 1.0 and above |
|
IBM z/OS Version 1.07 and above |
|
Multiprocessor hardware configuration |
