RFR(XS): 8001425: G1: Change the default values for certain G1 specific flags
by John Cuthbertson 16 Jan '13

16 Jan '13

Hi Everyone, Can I have a couple of volunteers look of the code changes for this CR? The webrev can be found at: http://cr.openjdk.java.net/~johnc/8001425/webrev.0/ Background: These changes change the default values of: G1MixedGCLiveThresholdPercent from 90 down to 65 This means that we we don't consider regions with a live occupancy > 65% as good candidates for collection during the next mixed GC phase. Evacuating regions that have a high live occupancy can get expensive and a 90% cut off was deemed to be too high. G1HeapWastePercent up from 5% to 10% This means that we are prepared to sacrifice 10% of the heap to avoid really expensive mixed GCs. G1MixedGCCountTarget up from 4 to 8 We can do up to 8 mixed GCs after a marking cycle instead of 4. This should mean that an individual mixed GC is less expensive and we should collect more regions before we reach the regions that are really expensive to collect. And for heaps no more than 4GB: G1NewSizePercent is reduced from 20% to 5%. This value was placing a lower bound on how far we could shrink the young generation. 20% was deemed to be too high. G1MaxNewSizePercent is reduced from 80% to 60%. A value of 80% was allowing the young generation to grow too large increasing the possibility of evacuation failures. These new values have been suggested by the performance team based upon their tuning experiments (including feedback from people the performance team has helped out). Going forward I think some of these values should be set dynamically. For example G1MixedGCLiveThresholdPercent could be tied to the overall heap occupancy. Thanks, JohnC

Request for review (S): 8006242: G1: WorkerDataArray<T>::verify() too strict for double calculations
by Bengt Rutisson 16 Jan '13

16 Jan '13

Hi all, Could I have a couple of reviews for this small change? http://cr.openjdk.java.net/~brutisso/8006242/webrev.00/ Thanks to John Cuthbertson for finding this bug and providing excellent data to track down the issue. From the bug report: In non-product builds the WorkerDataArrays in G1 are initialized to -1 in WorkerDataArray<T>::reset() when a GC starts. At the end of a GC WorkerDataArray<T>::verify() verifies that all entries in a WorkerDataArray has been set. Currently it does this by asserting that the entries are >= 0. This is fine in theory since the entries should contain counts or times that are all positive. The problem is that some WorkerDataArrays are of type double. And some of those are set up through calculations using doubles. If those calculations result in a value close to 0 we could end up with a value slightly less than 0 since double calculations don't have full precision. All we really want to verify is that all the entries were set. So, it should be enough to verify that entries do not contain the value set by the reset() method. Bengt
