Significantly increased number of allocations in v0.16.4 compared to v0.16.3

[Yue-Zhengyuan]

I was doing SimpleUpdate benchmark tests using the current master branch of PEPSKit using the following script:

using Random
using TensorKit
using PEPSKit
using BenchmarkTools

Nr, Nc = 2, 2
ham = j1_j2_model(
    ComplexF64, Trivial, InfiniteSquare(Nr, Nc);
    J1 = 1.0, J2 = 0.0, sublattice = false
)
D = 8
Vvir = ℂ^D
state = InfinitePEPS(randn, ComplexF64, ℂ^2, Vvir; unitcell = (2, 2))
wts = SUWeight(state)
alg = SimpleUpdate(; trunc = truncrank(D))
evolver = TimeEvolver(state, ham, 0.1, 10, alg, wts)
circuit = evolver.gate

function test_suiter()
    return PEPSKit.su_iter(state, circuit, alg, wts)
end

@btime test_suiter()

Using TensorKit v0.16.4, the output is

13.033 ms (43992 allocations: 50.63 MiB)

If I downgrade to v0.16.3, I get

12.372 ms (25368 allocations: 49.86 MiB)

The number of allocations is almost 50% smaller with v0.16.3, though the speed change is not that dramatic. I haven't been able to produce a more minimal example. Is this something to worry about?

It is quite hard to gauge what is going on, since the number of allocations does not necessarily map directly to a performance regression. Since the whole cache management system got rewritten, it isn't odd that this is happening per se, since I think we now have to retrieve cache data in 2 steps, rather than in 1, and there is some allocations associated with that. If you have a more in-depth profile view it might be that we have a type instability somewhere, which is causing this?

[Yue-Zhengyuan]

I came up with a more minimal code that benchmarks the "apply_gate" step in simple update.

using BenchmarkTools
using Profile
using TensorKit

function contract(
        a::AbstractTensorMap{T, S, 2, 1}, b::AbstractTensorMap{T, S, 2, 1},
        gate::AbstractTensorMap{T, S, 2, 2}
    ) where {T, S}
    return @tensor a2b2[-1 -2; -3 -4] := gate[-2 -3; 1 2] * a[-1 1 3] * b[3 2 -4]
end

Vp, Vv = ℂ^4, ℂ^10
# P.S. if I use these, allocation number difference becomes much smaller.
# Vp = Vect[FermionParity ⊠ U1Irrep]((0, 0) => 2, (1, 1) => 1, (1, -1) => 1)
# Vv = Vect[FermionParity ⊠ U1Irrep]((0, 0) => 4, (1, 1) => 2, (1, -1) => 2, (0, 2) => 1, (0, -2) => 1)
a = randn(Vv ⊗ Vp ← Vv)
b = randn(Vv ⊗ Vp ← Vv)
gate = randn(Vp ⊗ Vp ← Vp ⊗ Vp)
a2b2 = contract(a, b, gate)

@btime contract($a, $b, $gate)
Profile.Allocs.clear()
Profile.Allocs.@profile sample_rate=1.0 contract(a, b, gate)

results = Profile.Allocs.fetch()
n_alloc = length(results.allocs)
@info "Length of results.allocs = $(n_alloc)"
for item in results.allocs
    println(item)
end

Good news is that if I increase the bond dimension, the relative differences in execution time and memory allocation of the two versions become smaller. So this is indeed caused by changes in bookkeeping code, instead of performance regression in contraction/decomposition that should scale with the bond dimension.

Below is the output for v0.16.3

I do see many Anys in both versions. Does it indicate type instability somewhere?

[Yue-Zhengyuan]

In v0.16.3, there are 20 allocations of FusionBlockStructure.

In #387, FusionBlockStructure is separated to SectorStructure and DegeneracyStructure. Here in v0.16.5, I observe 6 allocations of SectorStructure and 20 allocations of DegeneracyStructure.

So naively the numbers don't add up.

[lkdvos]

Actually I think they might, this was the entire point: the sector structure is shared whenever only the degeneracy changes (that was the entire point), and so it should indeed cache less sector stuff than degeneracy stuff :)

[lkdvos]

Will close this for now since it seems like this is expected and the actual size allocated hasn't increased drastically, but happy to reopen if this turns out to be an issue.
