WorkSetConcurrencyLimitArgument
WORK_API void WorkSetConcurrencyLimitArgument(int n)
Sanitize n as described below and set the concurrency limit accordingly.

WorkGetPhysicalConcurrencyLimit
WORK_API unsigned WorkGetPhysicalConcurrencyLimit()
Return the number of physical execution cores available to the program.

WorkSetMaximumConcurrencyLimit
WORK_API void WorkSetMaximumConcurrencyLimit()
Set the concurrency limit to be the maximum recommended for the hardware on which it's running.

WorkGetConcurrencyLimit
WORK_API unsigned WorkGetConcurrencyLimit()
Return the current concurrency limit, always >= 1.

WorkSetConcurrencyLimit
WORK_API void WorkSetConcurrencyLimit(unsigned n)
Set the concurrency limit to n, if n is a non-zero value.

WorkHasConcurrency
WORK_API bool WorkHasConcurrency()
Return true if WorkGetPhysicalConcurrencyLimit() returns a number greater than 1 and PXR_WORK_THREAD_...
