Class PiParallel
java.lang.Object
org.apfloat.samples.Pi
org.apfloat.samples.PiParallel
- Direct Known Subclasses:
- PiDistributed
public class PiParallel
- extends Pi
Calculates pi using multiple threads in parallel.
Note that to get any performance gain from running many
threads in parallel, the JVM must be executing native threads.
If the JVM is running in green threads mode, there is no
advantage of having multiple threads, as the JVM will in fact
execute just one thread and divide its time to multiple
simulated threads.
