but then you probably want it to explode?

00:00

because most likely it didn't fully finish successfuly

jnthn

Yes, but if it didn't, you could have accidentally relied on it not doing so...somehow.

But given this was only a problem for certain ways of it getting killed, and normal unsuccessful exits already exploded, I suspect it will not hurt so much.

00:01

AlexDaniel

if this breaks my own code I'd be so pissed :D

00:02

pmurias

jnthn: I get 3.5 for moar, 14s for truffle and 35s for the jvm

00:06

interesting why MasterDuke and mine jvm times are that different

MasterDuke

pmurias: oh, i bet i'm still using the graal jdk/jre to run the old code

00:07

hm, nope, don't think so

00:08

Xliff

Rig diffs.

00:10

pmurias

MasterDuke: I'm using the graalvm-ce-19.2.1 for both

Xliff

As in... what are your respective machine specs...

MasterDuke

openjdk version "13.0.1" 2019-10-15 OpenJDK Runtime Environment (build 13.0.1+9) OpenJDK 64-Bit Server VM (build 13.0.1+9, mixed mode)

for regular code

OpenJDK 64-Bit GraalVM CE 19.2.1 (build 25.232-b07-jvmci-19.2-b03, mixed mode) for truffle

00:11

and ryzen 3700x is the hardware

00:12

pmurias

MasterDuke: have you compared running the old backend with the GraalVM CE (just using a regular ./nqp-j with the same java)

MasterDuke

pmurias: i haven't. i'll do that tomorrow, but i'll have to rebuild it (i just tried without and got `Error: A JNI error has occurred, please check your installation and try againException in thread "main" java.lang.UnsupportedClassVersionError: org/perl6/nqp/runtime/CompilationUnit has been compiled by a more recent version of the Java Runtime

00:14

(class file version 53.0), this version of the Java Runtime only recognizes class file versions up to 52.0`

pmurias

hmm, seem super weird

00:15

Xliff

Would someone appreciate another benchmark?

00:16

I could run one, if someone told me how.

$ perl6 scripts/dependencies.pl6 -> 20

Oops

00:17

pmurias

MasterDuke: you get that error for the nqp-j in a non-truffle checkout?

Xliff

perl6 -e '$*KERNEL.cpu-cores.say' # 20

MasterDuke

pmurias: yeah, i just put the graal directories at the beginning of my PATH (like they are when i run the truffle code)

00:18

00:18 tyil[m] left

pmurias

Xliff: I have to hit the bed asap as I'm not thinking straigh, stayed up too late to see how the optimized WVal will work

00:19

00:19 tyil[m] joined

MasterDuke

Xliff: nqp code is `class Point { has $!x; has $!y; method new(:$x, :$y) { my $obj := nqp::create(self); nqp::bindattr($obj, Point, q|$!x|, $x); nqp::bindattr($obj, Point, q|$!y|, $y); $obj; }; method x() { $!x }; method y() { $!y } }; my $total := 0; my int $i := -1; while ++$i < 50000000 { my $p := Point.new(x => 2, y => 3); $total := $total +

00:19

$p.x + $p.y; }; say($total)`

how long does that take with the jvm backend for you?

00:20

but i too need to get to bed

Xliff

MasterDuke: I don't think I build the jvm backend. Let me get that running. I will .tell you and pmurias the results.

pmurias

jnthn: the truffle backend still doesn't have method call optimized properly (with polymorphic inline caching) one I figure out how to do it in a way that's actually faster the benchmarks should be more representative

00:22

MasterDuke

Xliff: this always bites me. if you get weird errors during build, make sure you're not parallelizing your make call (i.e., `make install`, not `make -j16 install`)

Xliff

MasterDuke++ # Thanks on the heads up!

00:23

"javac: invalid flag: --release" ??

I'm using openjdk-8-jdk

MasterDuke

-version

Xliff

Feh. Now installing -14

Ah. There we go.

Exception in thread "Thread-4" org.perl6.nqp.runtime.UnwindException

00:36

I'm going to leave the build running, but the process seems hung at this point with it repeating that exception message.

00:42

MasterDuke, pmurias: Aborting jvm make... something isn't write either with my system or the build process. It is hanging at: '/home/home/cbwood/Projects/rakudobrew/versions/jvm-2019.07.1/perl6-j' '/home/home/cbwood/Projects/rakudobrew/versions/jvm-2019.07.1/tools/build/install-core-dist.p6'
