Can someone help with this?

[ChrisRackauckas]

@chriselrod do you know what can cause this?

[chriselrod]

@daammiix
I think this is related:
JuliaSIMD/VectorizationBase.jl#27
I.e., "Hwloc has proven to be unreliable".

Earlier, I used CpuId.jl instead, which only supports Intel and AMD, but has been pretty reliable for them.
For unsupported CPUs, I just made some basic assumptions.
I think I should:

1. Depend on CpuId.jl again, and use it for Sys.ARCH === :x86_64 or Sys.ARCH === :i686.
2. Use Hwloc.jl otherwise.

I'll only using the one library based on Sys.ARCH, but it would be nice if there were a way to not require both of these to be dependencies.

[chriselrod]

@daammiix I would like to know if you are in fact on an x86 cpu. If you are not, the changes I propose above will not help you. Mind showing me

versioninfo()

?

I'd also like to know if you're doing anything like running in a VM or similar basic details about your setup. It'd help me to know on which sorts of systems/setups CpuId doesn't work well.

Could you show me the outputs of:

using CpuId
cachesize()
cachelinesize()
cpucores()

using Hwloc
Hwloc.topology_load()

Great, thanks.

Now, does this work:

using Hwloc

const TOPOLOGY = Hwloc.topology_load();
const CACHE = TOPOLOGY.children[1].children[1];
const COUNTS = Hwloc.histmap(TOPOLOGY);
# TODO: Makes topological assumptions that aren't right for
# multiple nodes or with >3 or <3 levels of Cache.

const CACHE_COUNT = (
    COUNTS[:L1Cache],
    COUNTS[:L2Cache],
    COUNTS[:L3Cache],
    COUNTS[:L4Cache]
)
const NUM_CORES = COUNTS[:Core]

const CACHE_LEVELS = something(findfirst(isequal(0), CACHE_COUNT) - 1, length(CACHE_COUNT) + 1)

function define_cache(N)
    if N > CACHE_LEVELS
        return (
            size = nothing,
            depth = nothing,
            linesize = nothing,
            associativity = nothing,
            type = nothing
        )
    end
    cache_name = (:L1Cache, :L2Cache, :L3Cache, :L4Cache)[N]
    c = first(t for t in TOPOLOGY if t.type_ == cache_name && t.attr.depth == N).attr
    (
        size = c.size,
        depth = c.depth,
        linesize = c.linesize,
        associativity = c.associativity,
        type = c.type_
    )
end


const L₁CACHE = define_cache(1)
const L₂CACHE = define_cache(2)
const L₃CACHE = define_cache(3)
const L₄CACHE = define_cache(4)
"""

const CACHE_SIZE = (
    L₁CACHE.size,
    L₂CACHE.size,
    L₃CACHE.size,

[chriselrod]

I posted two code snippets.

The first one also gave me that error, but I fixed it in the second.

Can you confirm you get that with the second code snippet (the one I did not delete) gives you that error?

[daammiix]

@chriselrod
It works now,no errors,what next should i do?

[chriselrod]

Okay, thanks, I'll replace the code that caused your error in VectorizationBase with that and make a new release.

I'll post here once that happens so you can update your packages and (assuming nothing else goes wrong) precompile DifferentialEquations.

[daammiix]

@chriselrod
Okey,thanks.

[chriselrod]

It's merged. Things should work after updating packages (on VectorizationBase 0.13.12+).

[daammiix]

@chriselrod
Yeah,its working,thank You a lot man.
