JobSystemThreadPool

public JobSystemThreadPool(int maxJobs,
 int maxBarriers)

Instantiate a job system with the specified limits.

Parameters:

maxJobs - the maximum number of jobs the system can allocate (>1)

maxBarriers - the maximum number of barriers the system can allocate

JobSystemThreadPool

public JobSystemThreadPool(int maxJobs,
 int maxBarriers,
 int numThreads)

Instantiate a job system with the specified limits.

Parameters:

maxJobs - the maximum number of jobs the system can allocate (>1)

maxBarriers - the maximum number of barriers the system can allocate

numThreads - the number of worker threads to start (≥0) or -1 to autodetect

Method Details

setNumThreads

public void setNumThreads(int numThreads)

Alter the number of worker threads. This is one less than the maximum number of jobs that can execute concurrently.

Parameters:

numThreads - the desired number of threads (≥0)
