<cpu_list>

Each <element> specifies a processor on which the thread may run.

<cpu_list>
    <element>value</element>
</cpu_list>

Only applies to platforms that support controlling CPU core affinity (see 21.5 Controlling CPU Core Affinity for RTI Threads and the RTI Connext DDS Core Libraries Platform Notes).

<cpu_
rotation>

Determines how the CPUs in <cpu_list> will be used by the thread. The value can be either:

• THREAD_SETTINGS_CPU_NO_ROTATION

The thread can run on any listed processor, as determined by OS scheduling.

• THREAD_SETTINGS_CPU_RR_ROTATION

The thread will be assigned a CPU from the list in round-robin order.

Only applies to platforms that support controlling CPU core affinity (see the RTI Connext DDS Core Libraries Platform Notes).

<mask>

A collection of flags used to configure threads of execution. Not all of these options may be relevant for all operating systems. May include these bits:

• STDIO
• FLOATING_POINT
• REALTIME_PRIORITY
• PRIORITY_ENFORCE

It can also be set to a combination of the above bits by using the “or” symbol (|), such as STDIO|FLOATING_POINT.

Default: MASK_DEFAULT

<priority>

Thread priority. The value can be specified as an unsigned integer or one of the following strings.

• THREAD_PRIORITY_DEFAULT
• THREAD_PRIORITY_HIGH
• THREAD_PRIORITY_ABOVE_NORMAL
• THREAD_PRIORITY_NORMAL
• THREAD_PRIORITY_BELOW_NORMAL
• THREAD_PRIORITY_LOW

When using an unsigned integer, the allowed range is platform-dependent.

When thread priorities are configured using XML, the values are considered native priorities.

Example:

<thread>
    <mask>STDIO|FLOATING_POINT</mask>
	<priority>10</priority>
	<stack_size>THREAD_STACK_SIZE_DEFAULT</stack_size>
</thread>

When the XML file is loaded using the Java API, the priority is a native priority, not a Java thread priority.
