[bug#58100] cbqn currently targets AVX2

[bug#58100] cbqn currently targets AVX2

[Christopher Rodriguez]

[-- Attachment #1: Type: text/plain, Size: 503 bytes --]

Hey All,

Came to my attention today that cbqn (which I recently submitted the
package for) was assuming a CPU with AVX2 extensions when built as I had
originally packaged it.

I have a patch to fix this; cbqn now will target a generic CPU, and the
AVX2 optimizations have been moved to their own package, cbqn-singeli.

Let me know what I can improve!

[bug#58100] [PATCH] gnu: cbqn: factor out singeli into derivative package.

[Christopher Rodriguez]

Persuant to a recent conversation[1] with upstream, I've factored the
AVX2-dependent builds into their own package (defaulting to a generic build
instead).

Instead of providing a singeli variant, would just tuning the package
suffice?  If not, I think we should try to properly unbundle singeli
(as in build an actual singeli package) before adding another package
variant.  Then, you could use existing patterns to decide whether to
use singeli by making it an input or not.

Thank You for pointing me in the right direction; I will ensure a
standardized changelog in my revised patch after reading all of the
linked info.

I am bumping the commit from 9c1cbdc99863b1da0116df61cd832137b196dc5c to
46501ac819c8f21c69d7d2ba4b0457a7356f5e42 (another commit was made when
closing the above-linked issue) as the new commit is the most recent one
for this un-tagged project.

There is no 'release' to package, and so in order to stay up to date
regular updates of this package's commit will likely be necessary.

I can see why the bootstrap commit might stay the same, however. Would
it be better to solely amend the commit on the actual installable
package instead?

> Okay

I have actually just re-read the documentation after the abovementioned
most recent commit, and noticed a surviving line in the upstream
`README.md`[1]:

`make PIE=""` on ARM CPUs (incl. Android & M1)

Perhaps I can incorporate this into the package to allow it to build on
aarch64 as well as x86_64? Though as mentioned in the original upstream
issue, I think there is a problem with a dependent package… perhaps this
should be saved for a separate issue, then.

> Instead of providing a singeli variant, would just tuning the package
> suffice?
This was actually my biggest question when making the patch. I chose a
singeli variant because there is no architecture detection at all in the
makefile; it relies entirely on the specified targets ("o3", "c", etc)
to decide what to build for.

As an example: Switching the target from "o3n-singeli" to "o3"
immediately changed the entire build, preventing it from looking at all
for Singeli sources, even though I had yet to unlink them from the
source directory.

Is there a preferred method for this kind of build structure in a Guix
package? I suppose I could do a (cond *) in the make flags… maybe
referencing a variable for the target? I don't know what variable that
might be, though, as we would not only be looking for an x86_64 target,
but specifically that the underlying system supports AVX2…

In general, I would much prefer to keep it as one package. I think it is
much easier to maintain that way, and makes the user experience much
easier as well. But I'm sorry to report that I'm unaware of how best to
implement this, and would greatly appreciate some advice.

As for unbundling singeli: Running singeli requires a version of cbqn
built with or without singeli support. Building a version of cbqn with
singeli support requires the /source/ for singeli to be present in the
build directory at build time, not a precompiled binary. Singeli itself
is actually just a BQN script[2], and not a compiled binary at all, and
is a transpiler from BQN to IR/C. It's used in the optimized version to
transpile/compile the SIMD algorithms (sic, I am unfamiliar with this
concept).

In short, to unbundle singeli, we can just avoid including singeli in
the build, as in the revised cbqn package in the patch. We could make a
package for singeli that uses an installed bqn binary from any cbqn
package, but we would still need the sources present at build time due
to the way they are used and called in the build script. Fully
decoupling the optimized cbqn from singeli would require rewriting the
parts of the build that locate and run the singeli script, and (I think)
is more suited to an upstream patch than a package definition. I have
opened an issue regarding this possibility with upstream as of this
email[3].

(FWIW, I've also opened an issue regarding release tagging[4], though
from my previous correspondence with upstream I'm fairly certain a
release tag is not yet something they are comfortable with).

project and those of GNU in general. I hope You have a great day!

There is no policy in Guix to tail untagged projects. For personal
experimentation, use transformations, e.g. --with-branch. But even if
there is a good reason to bump the package, use a separate commit for
this.

Staying up to date is not good in and of itself, you have to evaluate
costs and benefits. Right now, you provided neither.

I have no hard stance on this. While one could argue that it'd be
better for bootstrap binaries to be unmoving, this doesn't seem to
apply here. Other than that, it's better for bootstrap paths to be
short, see e.g. Rust.

I'm pretty sure we'd like to specify e.g. -shared instead.

It ought to at very least be a separate commit.

That would be handled by the tuning compiler.

My question is: what does singeli even do for cbqn?  If it's a
compiler, can you not simply run that compiler in a separate phase?

I'm pretty sure that finding the right arguments to copy-build-system
would be the first problem here.  As for the comment from dzaima, I
don't quite understand why you'd need two versions of cbqn.  Assume you
already have one built without singeli, how is it expected to change
once singeli is added?

On that note, do you even need CBQN to run singeli or does any
(conforming) BQN implementation suffice?  For instance, you could try
building BQN with CBQN and then use that to run singeli, or use the
Java BQN.

That's fair and well, but to come back to the point made earlier, we
probably won't go to a newer commit unless there's an important
feature, bug fix, etc.  You can spend a lot of time optimizing without
substantially changing anything and trailing every single step on this
way would be a fool's errand.

Cheers

Hi Liliana,

This series of patches that you sent LGTM!

However, how does it relate to AVX2-specific builds?  Anyhow, as you
suggested in the thread, it’d be a good idea to add a ‘tunable?’
property.

Thanks,
Ludo’.

IIUC, singeli is some tool that emits avx2-specific opcodes and the
singeli builds of cbqn use that somehw; I admit, I do not completely
understand what's going on on their side.

Will simply adding (tunable? . #t) as a property be enough?  Also
related to the signeli thing, do we have the means to create special
build flows for tuned packages?

Cheers

Oh, I see.

Yes, ci.guix builds tunable packages for several x86_64 ISA variants,
which are listed in (gnu ci).

Thanks,
