Subject [jira] Updated: (HARMONY-5964) a garbage collection for CMP
Date Sat, 30 Aug 2008 13:40:44 GMT

     [ https://issues.apache.org/jira/browse/HARMONY-5964?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

YangBin updated HARMONY-5964:
-----------------------------

    Description: 
I have designed a "STW" garbage collection for CMP. Its performance and total pause time is
better than the garbage collection Harmony M2 on Intel dual-core platform. (My development
environment is 5.0M2). In the attachment there are the souce code, compile configure file
and test report.

-XX:gc.corenum=core number        default value is 2       i.e    -XX:gc.corenum=2
-XX:gc.blocksize=block size             default value is 64     i.e    -XX:gc.blocksize=64

 I am very glad to get some opinion for everyone. 
Thank you.
