prefetch instructions in Hotspot

[Mahmood Naderan]

Hi, 

I have some naive questions so any answer to the following questions are appreciated.

1- I have open-jdk 1.6 and 1.7. Do I have to install additional things? 

2- I want to use some intrinsics (readPrefetch) but there are little information on how to use the intrinsics. Is there any example for that? The only thing I see is https://bugs.openjdk.java.net/browse/JDK-2146656



 
Regards,
Mahmood
