Re-enable cgroup test for s390x #189

omajid · 2022-02-10T14:59:37Z

Cgroup support is currently not implemented on mono (used on s390x). We are going to, shortly, disable that test on s390x.

But upstream is working on a fix, we should enable the test for s390x when mono gets support for cgroups.

omajid · 2022-10-27T01:49:44Z

This was fixed in mono with dotnet/runtime#74237 and should be a part of 7.0 now. This test is now expected to pass on 7.0 for mono runtimes too.

omajid · 2022-10-27T19:06:02Z

I have run this test on ppc64le and s390x now and both fail:

s390x

@tmds @uweigand @janani66 Does this seem expected? Any idea what's going on? Is it a test bug or a bug in mono?

tmds · 2022-10-27T19:15:22Z

209715200 -lt 100000000

means GC.GetGCMemoryInfo().TotalAvailableMemoryBytes returns exactly 200MB, which is more than the 100MB limit we've set.

If you vary the MemoryLimit, how does TotalAvailableMemoryBytes behave?

janani66 · 2022-10-27T19:50:06Z

@tmds Well changing the MemoryLimit doesn't seem to change anything on ppc64le running .NET7 RC2 code

[cgroup-limit]#systemd-run -q --scope -p CPUQuota=100% -p MemoryLimit=250M bin/Debug/net7.0/cgroup-limit

janani66 · 2022-10-27T19:51:58Z

BTW, I am testing with .NET7.0 RC2 which has:
[release/7.0] [mono] Determine any memory/CPU limitations from sysfs cgroup#74881 (dotnet/runtime#74881)

But it does not have:
[release/7.0][mono][sgen] Update memory load information after world is resumed #76534 (dotnet/runtime#76534).
Is this second commit also needed for Cgroup Limits to work? Note: This second commit dotnet/runtime#76534 landed in the .NET7 GA code

tmds · 2022-10-28T04:07:05Z

@omajid this is not a blocker for 7.0, right?

uweigand · 2022-10-28T09:26:35Z

Hmm. Looking at the sources, I see:

                                restricted_limit = (3 * restricted_limit) / 4;  /* Use 75% limit of container */
                        }
                }
                return (restricted_limit < MINMEMSZ ? MINMEMSZ :        /* Use at least 20MB */
                        (restricted_limit < memsize ? restricted_limit : memsize));

However, the variable MINMEMSZ is actually defined as:

#define MINMEMSZ 209715200      /* Minimum restricted memory size */

So I believe the intent was to allow using "75% of the container limit, but at least 20MB" - but the code actually does "75% of the container limit, but at least 200MB". This seems to match the measurements above. @janani66 can you try larger values? E.g. with 300MB container limit, you should be seeing more than 200MB.

@nealef, I'm assuming the comment is correct and this should really be 20MB instead of 200MB? I cannot find either limit in the CoreCLR implementation at first glance, so I'm not sure where these values come from ...

uweigand · 2022-10-28T09:27:59Z

@omajid if changing the MINMEMSZ variable fixes this, is this something that could be done for GA?

janani66 · 2022-10-28T13:33:11Z

@uweigand -- you nailed it

omajid · 2022-10-28T13:34:32Z

@omajid this is not a blocker for 7.0, right?

IMO, It's not a blocker. Most importantly, it's not a regression. It only affects mono (where cgroup was previously compleletey broken). If we have a fix, we can take it, or we can wait for a fix to flow in through a monthly servicing update.

@omajid if changing the MINMEMSZ variable fixes this, is this something that could be done for GA?

Yes. We don't have the final builds GA yet so we have some time to tweak things. Since this only affects mono, if you and @janani66 agree on a fix, We can include it. It would be nice to send a PR to dotnet/runtime for 7.0 though (for review/sanity-check and reduce our maintenance burden down the road).

uweigand · 2022-10-28T14:26:53Z

I've now found the corresponding place in CoreCLR, and it is indeed using 20 MB, not 200 MB. See the comment here:
https://github.com/dotnet/runtime/blob/a6f4527ebf2c3faa5b9f55e8a7acb12df4571425/src/coreclr/gc/gcpriv.h#L4062-L4067
and the implementation at around line 45176 in src/coreclr/gc/gc.cpp:

    // If the hard limit is specified, the user is saying even if the process is already
    // running in a container, use this limit for the GC heap.
    if (gc_heap::heap_hard_limit)
    {
#ifdef FEATURE_EVENT_TRACE
        gc_heap::hard_limit_config_p = true;
#endif //FEATURE_EVENT_TRACE
    }
    else
    {
        if (gc_heap::is_restricted_physical_mem)
        {
            uint64_t physical_mem_for_gc = gc_heap::total_physical_mem * (uint64_t)75 / (uint64_t)100;
            gc_heap::heap_hard_limit = (size_t)max ((20 * 1024 * 1024), physical_mem_for_gc);
        }
    }

The attached patch implements the obvious fix to change to 20 MB in Mono as well:
mono-cgroup-minmemsz-fix.txt

@nealef given that this is originally your implementation, could you move that forward as PRs in all affected branches as well? Thanks!

nealef · 2022-10-28T14:41:27Z

Will do. The irony is I had coded it as 20 *1024*1024 but was told I should use a #define and then incorrectly calculated the value instead of leaving it in that form.

See the comment here: https://github.com/dotnet/runtime/blob/a6f4527ebf2c3faa5b9f55e8a7acb12df4571425/src/coreclr/gc/gcpriv.h#L4062-L4067 and the implementation at around line 45176 in src/coreclr/gc/gc.cpp: // If the hard limit is specified, the user is saying even if the process is already // running in a container, use this limit for the GC heap. if (gc_heap::heap_hard_limit) { #ifdef FEATURE_EVENT_TRACE gc_heap::hard_limit_config_p = true; #endif //FEATURE_EVENT_TRACE } else { if (gc_heap::is_restricted_physical_mem) { uint64_t physical_mem_for_gc = gc_heap::total_physical_mem * (uint64_t)75 / (uint64_t)100; gc_heap::heap_hard_limit = (size_t)max ((20 * 1024 * 1024), physical_mem_for_gc); } } The attached patch implements the obvious fix to change to 20 MB in Mono as well: mono-cgroup-minmemsz-fix.txt<https://github.com/redhat-developer/dotnet-regular-tests/files/9889185/mono-cgroup-minmemsz-fix.txt> @nealef<https://github.com/nealef> given that this is originally your implementation, could you move that forward as PRs in all affected branches as well?
