jdk_time target fails on some arm32_linux nodes #3360

smlambert · 2024-01-29T19:04:02Z

Please set the title to indicate the test name and machine name where known.

As indicated by Jan 2024 CPU triage, in adoptium/aqa-tests#4982 (comment), the jdk_time test target was failing with timeouts on ci.adoptium.net arm32 nodes. It was able to pass on the temurin-compliance arm32 linux node.

To make it easy for the infrastructure team to repeat and diagnose, please
answer the following questions:

test suite/name (e.g, BUILD_LIST, TARGET, CUSTOM_TARGET)? BUILD_LIST=openjdk, TARGET=jdk_time
a link into recent Test_ job on https://ci.adoptium.net which showed the failure
- https://ci.adoptium.net/job/Test_openjdk11_hs_extended.openjdk_arm_linux/127/
- https://ci.adoptium.net/job/Grinder/8603
Hyperlink to re-run in Grinder:

Is there an existing issue elsewhere covering this? No
Which machine(s) does it work on? jck-equinix-containerized-ubuntu2004-aarch32-1
Which machine(s) does it fail on? https://ci.adoptium.net/label/hw.arch.aarch32&&ci.role.test&&sw.os.linux/

Looks like it times out when you run them in jdk_time together, but pass when running them individually.

I think the jdk_time test target might be a bit much for the docker static containers.

The grinder has caused test-docker-ubuntu2004-armv7l-4 to disconnect from jenkins

Passed on the odroid machine. Also passed on test-docker-ubuntu2004-armv7l-2 https://ci.adoptium.net/job/Grinder/8701/console

sxa · 2024-01-31T23:50:19Z

Interesting ...

@Haroon-Khel Are they all new containers and did you cap the CPU/memory on them? From the Grinder logs the run on both containers as mentioned in #3360 (comment) and #3360 (comment) were both running with -concurrency:81 on the jtreg command line (CPU cores/2+1. Those machines have 160 physical cores) but most of the containers should be started with options that restrict the containers to less than that. I'm not quite sure why the two container Grinders didn't show the same behaviour, but the odroid system had concurrency:1 so were potentially safer. I'm slightly surprised that a time related test would give a large load, but maybe we need to restrict those tests. I would have expected similar results on the aarch64 systems though, which are run on the same host 🤷🏻

Noting that the calculation for currency is the one I was looking at adjusting in adoptium/aqa-tests#4792 (in case you want to see where it is and play with it) but I don't think that will affect this particular situation.

Haroon-Khel · 2024-02-01T12:45:16Z

Ive updated my branch to run the test with concurrency:2
Rerunning on test-docker-ubuntu2004-armv7l-4 https://ci.adoptium.net/job/Grinder/8703/console

Are they all new containers and did you cap the CPU/memory on them?

Yes, the images are built with
docker build --cpu-period=100000 --cpu-quota=800000

And are run with
docker run --restart unless-stopped --cpus=4.0 --memory=6G

Bear in mind the jdk_time_2 tests passed on test-docker-ubuntu2004-armv7l-2, another static container but running on dockerhost-equinix-ubuntu2004-armv8-1 not dockerhost-equinix-ubuntu2204-armv8-1. Link to the grinder https://ci.adoptium.net/job/Grinder/8701/console -concurrency:81 is used

Haroon-Khel · 2024-02-01T12:51:47Z

https://ci.adoptium.net/job/Grinder/8703/console passed. So we need to limit concurrency on the docker static containers, and eventhough its passes with -concurrency:81 on some, it shouldnt be using a value this high

Haroon-Khel · 2024-02-01T13:03:35Z

adoptium/aqa-tests#4792 looks good, but I want to first look at why the test scripts are reporting 160 cores and not the set 4 (or whatever) cores of the docker containers

sxa · 2024-02-01T16:47:28Z

adoptium/aqa-tests#4792 looks good

Unfortunately I'm not yet convinced which is why it's still in draft, but I need to get back to it ;-)
It will be getting 160 cores from /proc/cpuinfo by default which is ok, but it ought to be reading the memory size from /sys/fs/cgroup/memory/memory.limit_in_bytes in the container (8589934592 bytes, converting to to Mb (8192 which goes into MEMORY_SIZE - this is the bit that will go wrong on the arm systems if my PR goes in) and then should set CONC (the value for concurrency) to 4 (Half the memory in Gb) as that's less than the number of cores (160)
All that logic is in https://github.com/adoptium/aqa-tests/blob/c27e9e649919f839444c638844e133a0d13edd04/openjdk/openjdk.mk#L52

Haroon-Khel · 2024-02-02T18:16:29Z

Im having some luck with --cpuset-cpus="0-3" instead of --cpus=4.0 to assign cpus to containers, and with nproc to find the number of processors

Container started with --cpus=4.0

root@d0a2dceb584c:/# nproc
160

Container started with --cpuset-cpus="0-3"

root@91b440680d8b:/# nproc
4

So a solution is to change https://github.com/adoptium/aqa-tests/blob/c27e9e649919f839444c638844e133a0d13edd04/openjdk/openjdk.mk#L22 to use nproc to find the number of cpus and to restart our arm32 containers with --cpuset-cpus="0-3"

Haroon-Khel · 2024-02-02T18:31:01Z

I've redeployed test-docker-ubuntu2004-armv7l-4 with --cpuset-cpus="0-3"

Rerunning jdk_time_2 from my branch on it, JTREG_TIMEOUT_OPTION is set back to normal. https://ci.adoptium.net/job/Grinder/8710/console

Concurrency should be 4/2 +1 =3 which shouldn't cause a timeout

Haroon-Khel · 2024-02-02T18:32:43Z

Looks good -timeoutFactor:8 -xml:verify -concurrency:3

Haroon-Khel · 2024-02-02T18:36:33Z

Grinder passed 👍🏻

Haroon-Khel · 2024-02-02T18:40:33Z

Passes for jdk11 too https://ci.adoptium.net/job/Grinder/8711/console

Haroon-Khel · 2024-02-05T13:37:57Z

The remaining arm32 nodes on dockerhost-equinix-ubuntu2204-armv8-1 have been restarted with --cpuset-cpus="0-3"

sxa · 2024-02-05T14:29:13Z

Do you know what the difference in behaviour is between the two options i.e. is there likely to be any downside to this change? We should check whether this is happening elsewhere too e g. X64 and ppcle systems to see if they are the same (trying to use more cores than they should be at present)

Nice find!
