cpuaddr2<br />

Use DEFINE <strong>CP</strong>U to do the following:<br />

v Add one or more processors to your virtual machine<br />

v Change the address of a defined virtual processor.<br />

cpuaddr<br />

defines a virtual processor for your virtual machine configuration at the address<br />

you specify for cpuaddr. You can specify multiple addresses in a list or in range<br />

form. If you specify a list of addresses, separate each address from the others<br />

by at least one blank. If you specify a range of addresses, specify the first <strong>and</strong><br />

last addresses in the range <strong>and</strong> put a hyphen between them. The processor<br />

addresses can be any value from 0 to 3F; the initial address of your base<br />

processor is specified in your system directory entry, or it defaults to 0.<br />

cpuaddr cpuaddr<br />

identifies a list of addresses or ranges delimited by blanks.<br />

DEFINE <strong>CP</strong>U<br />

cpuaddr1-cpuaddr2<br />

specifies a nonwrapping pair of addresses separated by a hyphen (-) <strong>and</strong> not<br />

separated by any blanks.<br />

cpuaddr1 AS <strong>CP</strong>U cpuaddr2<br />

changes the address of the processor currently defined at cpuaddr1 to the<br />

address cpuaddr2.<br />

1. Your system directory entry specifies the maximum number of processors you<br />

can define for your virtual machine.<br />

2. If your system directory entry contains multiple <strong>CP</strong>U statements that specify a<br />

virtual multiprocessing configuration, that configuration is created for you at<br />

logon time. If your directory entry does not specify additional processors, your<br />

virtual machine logs on as a uniprocessor. Once logged on, you can use<br />

DEFINE <strong>CP</strong>U to modify your virtual configuration.<br />

3. All future <strong>CP</strong> responses are prefaced with the number of the <strong>CP</strong>U that issues<br />

the responses. This continues as long as you have the virtual multiprocessor<br />

configuration.<br />
