Ioi, I can confirm that current patchset works on aarch64 as expected. It passes all tests in runtime/SharedArchiveFile. I'll re-check it when other version of fix/more tests become available. -Dmitry On 30.10.2017 18:52, Ioi Lam wrote: > Hi Dmitry, > > In the latest JDK 10 repo, is_jrt has been renamed to is_modules_image. > Please change the code accordingly. > > I will post my latest diff soon, with some test cases as well. > > Thanks > > - Ioi > > > On 10/30/17 4:04 AM, Dmitry Samersoff wrote: >> Ioi, >> >> I'd tried to apply your patch to latest open JDK10 and >> the compilation fails with: >> >> /root/dsamersoff/ESC/appcds/hs/src/hotspot/share/classfile/systemDictionaryShared.cpp:400:16: >> >> error: ‘class SharedClassPathEntry’ has no member named ‘is_jrt’ >> >> Did I miss something? >> >> -Dmitry >> >> On 13.10.2017 02:48, Ioi Lam wrote: >>> Hi, >>> >>> Please review this change set. >>> >>> http://cr.openjdk.java.net/~iklam/jdk10/8188791-open-appcds-impl.v01/ >>> https://bugs.openjdk.java.net/browse/JDK-8188791 >>> >>> This is the first step of implementing the following JEP, which moves >>> AppCDS from >>> closed repos into the openjdk repo: >>> >>> https://bugs.openjdk.java.net/browse/JDK-8185996 >>> >>> In JDK 9, significant portion of AppCDS code resided in the closed repo. >>> As part >>> of the open-sourcing effort of JDK 18.3, we will move the source code >>> into the >>> open repo. >>> >>> In this changeset, the code is moved verbatim as much as possible.

[10] RFR: 8189101 - AARCH64: AARCH64: string compare intrinsic doesn't use prefetch
by Dmitrij Pochepko 30 Oct '17

30 Oct '17

Hi, this is a second pre-review as part of JEP “Improve performance of String and Array operations on AArch64” for another improved intrinsics to get early feedback. Please pre-review patch for 8189101 - “AARCH64: AARCH64: string compare intrinsic doesn't use prefetch” This patch moves code for long string processing to a stub and reorganize it. For large strings code was re-organized, added large 64-byte unrolled loops and prefetch. Webrev is available at [1]. Surpisingly, it helps a bit for small strings, because code for string comparison node is now shorter, so, less icache lines needed to be populated to execute it. A benchmark was developed to measure performance [2], which contains 4 cases with various sizes: LL (latin1 vs latin1), LU (latin1 vs utf), UL (utf vs latin1) and UU (utf vs utf). I can see up to x5 performance on systems without h/w prefetcher (ThunderX) and up to 40% improvement on system with h/w prefetcher(Cortex A53). Raw performance numbers are at [3]. Charts for performance numbers above are: Cortex A53 [4] and ThunderX [5]. Testing: I've run java/lang/String (contains test for String::compareTo method) jtreg tests with both Xmixed and Xcomp modes and found no regressions. Any additional numbers on other systems are welcome, as well as early feedback on the code.

[10] RFR: 8187472 - AARCH64: array_equals intrinsic doesn't use prefetch for large arrays
by Dmitrij Pochepko 30 Oct '17

30 Oct '17

Hi, as part of JEP “Improve performance of String and Array operations on AArch64” I wanted to send out a pre-review for some of the improved intrinsics to get early feedback. This is the first in a row. Please pre-review patch for 8187472 - “AARCH64: array_equals intrinsic doesn't use prefetch for large arrays” which improves large array handling (small arrays are unaffected). In short, this patch uses large (64 byte) loop with prefetch instruction to handle large arrays, which is done in a stub. I can observe performance boost on systems without h/w prefetcher up to x6. System with hardware prefetching (Cortex A53 and some very modern ones) also benefit from this patch (15% improvement). I've tried a number of different versions (attached to JDK-8187472) with different load instructions (ldr/ldp/<simd>), slightly different code shapes, different data dependencies across registers, alignments, e.t.c. Version presented in webrev (version 2.6d from JDK-8187472 attachments) is the simplest from the fast ones (as measured on 3 systems available for testing). I've used this simple benchmark to measure performance: http://cr.openjdk.java.net/~dpochepk/8187472/ArrayEqualsBench.java Chart for ThunderX: http://cr.openjdk.java.net/~dpochepk/8187472/ThunderX.png Chart for Cortex A53(R-Pi): http://cr.openjdk.java.net/~dpochepk/8187472/R-Pi.png Raw numbers for ThunderX: http://cr.openjdk.java.net/~dpochepk/8187472/ThunderX.results.txt Raw numbers for R-Pi: http://cr.openjdk.java.net/~dpochepk/8187472/R-Pi.results.txt webrev: http://cr.openjdk.java.net/~dpochepk/8187472/webrev.01/ Testing: I've run existing jtreg test (java/util/Arrays/ArraysEqCmpTest.java) in both Xmixed and Xcomp and found no regressions. Any additional numbers on other systems are welcome, as well as early feedback on the code. Thanks, Dmitrij

ZeroTLAB and block zeroing
by Andrew Haley 26 Oct '17

26 Oct '17

MacroAssembler::tlab_refill() does not call MacroAssembler::zero_words(), so it does not use DC ZVA. It certainly could, and perhaps someone could try. It would remove most of our loops when allocating objects. It'd be interesting to see if this helps anything. -- Andrew Haley Java Platform Lead Engineer Red Hat UK Ltd. <https://www.redhat.com> EAC8 43EB D3EF DB98 CC77 2FAD A5CD 6035 332F A671

Bugzilla assignments
by Andrew Haley 25 Oct '17

25 Oct '17

>From now on, please send a brief email to this list when you assign a Bugzilla entry to someone. This is somewhat redundant because of the automatic emails, but I don't get to see assignments automatically, and it's good for all of us to know what each other are doing. -- Andrew Haley Java Platform Lead Engineer Red Hat UK Ltd. <https://www.redhat.com> EAC8 43EB D3EF DB98 CC77 2FAD A5CD 6035 332F A671
