likwid.jl's Issues

Switch group example (Marker API)

As far as I can see, there is no group switch in the example code at https://juliaperf.github.io/LIKWID.jl/dev/examples/perfmon/, that's why only the first group gets measured (| is the group delimiter). You would need to run your benchmark code twice, once for the first group, then "switch groups" and run your benchmark again for the second group measurement.
The two groups have different gids, so when reading the results/metrics, you have to specify the right gid.

NvMon.init([0])
gid = NvMon.add_event_set("FLOPS_DP")
NvMon.setup_counters(gid)
NvMon.start_counters()

Not sure yet whether this is an issue with likwid, LIKWID.jl, or the likwid installation on Noctua 2.

Could not load library "liblikwid"

EDIT - The particular test cases work fine if I started Julia as

likwid-perfctr -C 0 -g FLOPS_SP -G 0 -W FLOPS_SP -m julia

However, the tests still fail (log given as a post below)

I am getting the following issues when trying to use LIKWID. Starting the julia REPL as usual with $ julia (which might be wrong for LIKWID.jl?), executing ] test LIKWID, I get

Segfault on repeated evaluation

Including twice this code at the REPL gives me a segfault:

using LIKWID
using LinearAlgebra

a = randn(1000, 1000)
function f()
    a*a
end
peak = LinearAlgebra.peakflops() # FLOP/s

using STREAMBenchmark
bw = memory_bandwidth(write_allocate=false)[1] * (1024^2) #byte/s

# intensity is FLOP per byte
roof(intensity) = min(peak, intensity*bw)

NUM_THREADS = 1
cpustr = join(collect(0:NUM_THREADS-1), ",")
LIKWID.LIKWID_THREADS(cpustr)
# the location the marker file will be stored
LIKWID.LIKWID_FILEPATH(joinpath(@__DIR__, "likwid_marker.out"))
# Use the access daemon

# Events to measure
LIKWID.LIKWID_EVENTS("FLOPS_DP|L2|INSTR_RETIRED_ANY:FIXC0")

using LIKWID: PerfMon
Marker.init_nothreads()
PerfMon.init()
Marker.registerregion("total")

Marker.startregion("total")
for _ = 1:100
    f()
end
Marker.stopregion("total")

nevents, events, time, count = Marker.getregion("total")
Marker.close()

Segfault for unkown CPUs

When likwid fails to identify the CPU it returns an only partially initialized cpu info stuct. However during topology resolution (here

LIKWID.jl/src/topology.jl

Lines 79 to 80 in 5d2cd59

 unsafe_string(ci.name), 

 unsafe_string(ci.short_name),

) it is assumed that the strings for name and short_name are initialized.

Reproducible on master for likwid and LIKWID.jl, as well as for both latest releases.

`@nvmon`: Unreasonable metric values

using LIKWID
using CUDA
LIKWID.init_topology_gpu()

N = 10_000
a = 3.141f0 # Float32
x = CUDA.rand(Float32, N)
y = CUDA.rand(Float32, N)
z = CUDA.zeros(Float32, N)

saxpy!(z, a, x, y) = z .= a .* x .+ y
saxpy!(z, a, x, y); # warmup

metrics, events = @nvmon "FLOPS_SP" saxpy!(z, a, x, y);

gives

julia> metrics, events = @nvmon "FLOPS_SP" saxpy!(z, a, x, y);

The metric values don't make sense!?

sigabrt's on Julia 1.9 with native access

Hi there,
I'm having some problems with running LIKWID.jl on my cluster. This is what I've done so far with the native backend:

First I tried running @perfmon , it segfaulted because likwid v4.0.0 was installed and the LIKWID.jl bindings were generated against a newer version, so I asked the admins to update it to 5.2.2.

Tried running @perfmon again, this time I see a bunch of sigabrts but the Julia process stays alive and the command seemingly completes successfully (though I'm not sure I trust the results). From the stacktraces (see below) I guessed that the issue is this call in likwid to fork(): https://github.com/RRZE-HPC/likwid/blob/v5.2.2/src/access_x86_rdpmc.c#L101. I figured that the sigabrts are coming from the child processes, and that's why the main Julia process doesn't die.

That code to use rdpmc instructions was added in likwid v5.2.0, so then I tried installing v5.1.1. Unfortunately that segfaults as well because the LIKWID.jl bindings are for a newer version, specifically, this PR changed a struct. I checked the git history of likwid and that struct was changed after rdpmc support was added, so there's no version I can use that will work with LIKWID.jl's binding and doesn't have rdpmc support (and the earliest LIKWID.jl version that doesn't require that particular struct is v0.1.1, so I don't really want to downgrade that...).

TL;DR, @perfmon printed a bunch of sigabrt stacktraces every time I run it because of the way likwid checks for rdpmc support (I think) and I can't downgrade anything to get around it.

Then I tried with the perf_event backend and that kinda worked, modulo some permission errors:

Tutorial: put a function on the roofline model

Great package! As far as I understand it provides the information needed to locate an application on the roofline model but finding the info without screwing up feels a bit scary to me. Could an example be put in a tutorial or in the library, so that I could do something like roofline(f) and it'd plot the roofline model and locate f() on it?

(this is for teaching basic performance notions)

NvMon

Check GPU indexing consistency. Also, shoudl we start counting at 0 (like CUDA)?

Update mention of LIKWID.jl on FAU website

Once #10 is merged, we should update https://hpc.fau.de/2021/01/29/julia-interface-for-likwid/.

The tool video looked amaizing. Exactly what I need.
I tried to install and run it with the CPU version, but I stucked at:

I installed Likwid: I think I did exactly like it is mentioned in the video:

# Path were to install likwid
PREFIX ?= /home/master/.local#NO SPACE

# Set the default mode for MSR access.
# This can usually be overriden on the commandline.
# Valid values are: direct, accessdaemon and perf_event
ACCESSMODE = accessdaemon#NO SPACE

...
...

# Build LIKWID with NVIDIA interface (CUDA, CUPTI)
# For configuring include paths, go to CUDA section
NVIDIA_INTERFACE = false#NO SPACE

added: ] add LIKWID

(Also tried with this:
PREFIX ?= /usr/local#NO SPACE)

Both arrives to the same result that I missing the library. Should I load it explicitly with julia or what is this?

Broken tests

We have a few @test_broken. Figure out why they are broken and whether that's a bug on our or LIKWIDs side.

BinaryBuilder builds?

First I don't use the project. But maybe It would be easier to use if it was on Yggdrassil. I can contribute to this if you think it would be fine to add it.

Use `@threads :static` instead of `@threads`

Once JuliaLang/julia#44136 is merged (will likely be in Julia 1.8) @threads will default to @threads :dynamic instead of the previous @threads :static! We must therefore replace @threads by the more explicit @threads :static where necessary!

Hidden version requirements to liblikwid

I just saw your talk from JuliaCon 2023 that also mentioned LIKWID.jl and I was eager to try it out. 🚀

Unfortunately, trying the very first tutorial, I got a segfault. After some digging, I found the culprit: the definitions of CpuTopology between LIKWID.jl and the underlying liblikwid differed. My likwid.h version 5.1 (installed via apt) defines the CpuTopology struct without the numDies field, while LIKWID.jl version 0.4.4 defines its CpuTopology struct having numDies in position 4. Consequently, the fields are shifted when transferring the data from C to Julia: Julia's numDies contains C's numCoresPerSocket, ..., numCacheLevels contains the value of threadPool, which is a pointer. Wrapping cacheLevels (C's topologyTree) into an array of length numCacheLevels (C's threadPool) leads to the malformed memory accesses. 💥

likwid.h: https://github.com/RRZE-HPC/likwid/blob/v5.1/src/includes/likwid.h#L370-L380

typedef struct {
    uint32_t numHWThreads; /*!< \brief Amount of active HW threads in the system (e.g. in cpuset) */
    uint32_t activeHWThreads; /*!< \brief Amount of HW threads in the system and length of \a threadPool */
    uint32_t numSockets; /*!< \brief Amount of CPU sockets/packages in the system */
    uint32_t numCoresPerSocket; /*!< \brief Amount of physical cores in one CPU socket/package */
    uint32_t numThreadsPerCore; /*!< \brief Amount of HW threads in one physical CPU core */
    uint32_t numCacheLevels; /*!< \brief Amount of caches for each HW thread and length of \a cacheLevels */
    HWThread* threadPool; /*!< \brief List of all HW thread descriptions */
    CacheLevel*  cacheLevels; /*!< \brief List of all caches in the hierarchy */
    struct treeNode* topologyTree; /*!< \brief Anchor for a tree structure describing the system topology */
} CpuTopology;

Liblikwid.jl: https://github.com/JuliaPerf/LIKWID.jl/blob/v0.4.4/src/LibLikwid.jl#L640-L651

struct CpuTopology
    numHWThreads::UInt32
    activeHWThreads::UInt32
    numSockets::UInt32
    numDies::UInt32
    numCoresPerSocket::UInt32
    numThreadsPerCore::UInt32
    numCacheLevels::UInt32
    threadPool::Ptr{HWThread}
    cacheLevels::Ptr{CacheLevel}
    topologyTree::Ptr{treeNode}
end

The numDies field has been added in RRZE-HPC/likwid@a0ac14d, which according to GitHub shipped in likwid version 5.2 and onwards. Moving the numDies field to the end of the C struct is not an option, I guess, and removing numDies from LIKWID.jl as its not used anyways. Therefore, I would recommend:

Document the version requirements for liblikwid
Let LIKWID.jl fail gracefully, if it recognizes an unsupported version of liblikwid
Let LIKWID.jl bundle its own liblikwid
