Fwd: [concurrency-interest] ConcurrentHashMap footprint and contention improvements
by Doug Lea 22 Apr '11

22 Apr '11

Members of this list are also invited to check this out. I'm not sure if it will make Java7 schedule, but the improvements seem worthwhile given the increased use of ConcurrentHashMap inside the JDK (including multiple tables per class loader in JDK7.) -Doug -------- Original Message -------- Subject: [concurrency-interest] ConcurrentHashMap footprint and contention improvements Date: Tue, 12 Apr 2011 20:07:17 -0400 From: Doug Lea <dl(a)cs.oswego.edu> To: Concurrency-interest(a)cs.oswego.edu <Concurrency-interest(a)cs.oswego.edu> For years, we've known that ConcurrentHashMaps have initial footprints (over 1000 bytes using default constructor) that are too big for casual use. And that the best way to address this would be to use the Fences API to emulate "final field" memory model guarantees in the presence of lazy initialization. But we aren't releasing the Fences API. So I committed a version that instead uses Unsafe calls to essentially the same effect (reducing initial footprint to around 100 bytes, plus a few percent savings for large populated tables). Also, this version includes throughput improvements under contention (mainly by interleaving locking with probes, to absorb cache misses), which can double performance on big tables with many threads. While conceptually straightforward, these lead to many line-of-code changes. The main price paid for these improvements is a greater reliance of "volatile" vs "final" reads, which are essentially equivalent in cost on most machines, but can be more costly on ARM and POWER. Even on these though, the net effect should be positive. It would be helpful if members of this list could help check that this is so. The committed version is now in java.util.concurrent sources (at http://gee.cs.oswego.edu/dl/concurrency-interest/index.html) and can be run by getting jsr166.jar and using "java -Xbootclasspath/p:jsr166.jar" with any java7 build or binary (http://dlc.sun.com.edgesuite.net/jdk7/binaries/index.html) Also, as an alternative, I temporarily placed an unpackaged source version (with the class renamed "CHM") at http://gee.cs.oswego.edu/dl/wwwtmp/CHM.java You can compile and somehow run in any java6/7 JVM. While working on these changes, I also contemplated other more extensive redesigns, including Cliff Click's non-blocking version (http://sourceforge.net/projects/high-scale-lib/) which usually has better scalability with large numbers of threads solely using get and put, but not otherwise uniformly a better choice. -Doug _______________________________________________ Concurrency-interest mailing list Concurrency-interest(a)cs.oswego.edu http://cs.oswego.edu/mailman/listinfo/concurrency-interest
