administrative privileges. You can download PRIO using following links for 32 and 64 versions

supporting through Windows 7:

http://www.prnwatch.com/prio.exe

http://www.prnwatch.com/prio_x64.exe

Alternately, you could launch MSDMT_32.EXE via a batch file and set the priority for the

duration of each use by creating a Batch file such as DMT.BAT which contains:

cmd /C Start /high C:\MARS\MSDMT\MSDMT_32

SETTING PROCESSOR AFFINITY

If you have a computer with more than one processor, you can set Windows processes to use

different processors in order to make a program run faster or to isolate a particular program

that uses a lot of processing power. This is called Processor Affinity. Setting Processor Affinity

(a.k.a. CPU Pinning) limits the execution of the program or process to the selected processors

and might increase the programs performance but may decrease overall performance. The use

of Processor Affinity with the MS-DMT tool will depend on the CPU or CPU’s on the host PC and

the effects noted in performance.

Windows XP, Windows Vista, and Windows 7 applications by default run on all available cores of

the processor. If you have a dual or quad core processor, then you can set affinity to an

application to control which core of the processor an application can use, in this way you can

assign one application or a program to use only one physical processor or one core of a multi-

core processors while all other applications can run on other processor or cores. Although you

cannot set priority to system services but you can set affinity to applications, in this way you can

achieve a good overall performance. When installing additional software you need to check that

the installation does not invalidate your MS-DMT tools dedicated configuration or either its own

processor or core.

In Windows, you can force a process to run in a specific CPU just using the Task Manager (right

click your process and select “Set Affinity”). The “Set Affinity” command selection is available
