Update the version of Ipopt_jll

[amontoison]

I recompiled Ipopt with the release 2023.8.2 of SPRAL.

@amontoison let's merge this? I'm not sure if it will fix my issue, but I had trouble using SPRAL even though I followed the instructions here and exported the three environment variables in the terminal before starting Julia:

julia> optimize!(model)
Setting: "spral" is not a valid setting for Option: linear_solver. Check the option documentation.

### linear_solver (String)  ###
Category: Linear Solver
Description: Linear solver used for step computations.
Valid Settings:
    ma27 (load the Harwell routine MA27 from library at runtime)
    ma57 (load the Harwell routine MA57 from library at runtime)
    ma77 (load the Harwell routine HSL_MA77 from library at runtime)
    ma86 (load the Harwell routine MA86 from library at runtime)
    ma97 (load the Harwell routine MA97 from library at runtime)
    pardiso (load the Pardiso package from pardiso-project.org from user-provided library at runtime)
    mumps (use the Mumps package)
    custom (use custom linear solver (expert use))
Default: "mumps"
ERROR: IPOPT: Couldn't set option 'linear_solver' to value 'spral'.

@chriscoey what version of Ipopt were you using?

[chriscoey]

I was using v1.4.1 - up to date. I will try again when 1.4.2 gets tagged. All I did was paste the exports from the README (OMP_CANCELLATION=TRUE OMP_NESTED=TRUE OMP_PROC_BIND=TRUE, though now there's only two in the README) into the console then open julia 1.9.2 and run

using Ipopt, JuMP

# An optimization problem
model = Model(Ipopt.Optimizer)
@variable(model, x)
@objective(model, Min, (x - 2)^2)

# Use the linear solver SPRAL
set_attribute(model, "linear_solver", "spral")
optimize!(model)

Can we add any tests for SPRAL?

[odow]

No, I mean, what version of Ipopt the solver (Ipopt_jll, or the initial part of a log file)

[odow]

We didn't add tests because of the environment variable problem. But I guess we could

[chriscoey]

Oh sorry, here: version = "300.1400.400+0"

[chriscoey]

Upgraded to Ipopt v1.4.2, but my version of Ipopt_jll is still the same, and I still get the error above. The environment variables are correctly set:

ccoey@CCoey's Macbook Pro ~ % echo $OMP_CANCELLATION
TRUE
ccoey@CCoey's Macbook Pro ~ % echo $OMP_PROC_BIND   
TRUE

and I see this when printing ENV in Julia too.

[odow]

I think you need to more recent version of Ipopt_jll

[chriscoey]

Hm OK, what is the recommended way to keep that up to date? I naively thought (and I think users would think the same...) that updating Ipopt.jl, or doing ]up, would keep everything up to date, but I did that and it doesn't do anything to Ipopt_jll. So do I need to manually add Ipopt_jll and update that?

[odow]

JLLs are no different than any other dependency. You probably have some other compat holding you back. If you want to force a compat bound on Ipopt_jll, you'll need to add it as an explicit dependency.

[chriscoey]

Weird. Perhaps it was SCIP? I just did:

        Info Packages marked with ⌃ and ⌅ have new versions available, but those with ⌅ are restricted by compatibility constraints from upgrading. To see why use `status --outdated -m`

[chriscoey]

So SCIP's project.toml has ipopt_jll as a dep and no version bound, but also SCIP_jll has ipopt_jll as a dep plus a version upper bound. I think we should try to change SCIP_jll...

[chriscoey]

SCIP_PaPILO_jll does the same to ipopt_jll

[chriscoey]

And I can use SPRAL now that Ipopt_jll is updated 🥳
