| 2025-02-26 12:55:56 +0100 | <Athas> | We'll see if the memory issue has also been solved. |
| 2025-02-26 12:55:49 +0100 | <Athas> | The commented-out code seems to perform quite OK now: https://github.com/gradbench/gradbench/blob/main/tools/haskell/src/GradBench/KMeans.hs#L78-L95 |
| 2025-02-26 12:55:46 +0100 | <tomsmeding> | *faster |
| 2025-02-26 12:55:42 +0100 | <tomsmeding> | What function from Numeric.AD.Double aer you using in the version that doesn't get vaster? |
| 2025-02-26 12:55:28 +0100 | <tomsmeding> | interesting! |
| 2025-02-26 12:55:14 +0100 | <Athas> | When I use that version, I do see significant speedup with +ffi. |
| 2025-02-26 12:55:13 +0100 | <tomsmeding> | something something hessian jacobian product? |
| 2025-02-26 12:55:02 +0100 | <Athas> | But now I have an interesting result. Do you remember I had a version that "ought" to be faster, but wasn't? |
| 2025-02-26 12:54:58 +0100 | <tomsmeding> | the whole point of Numeric.AD.Double is that it optimises the `Reverse s Double` case |

| 2025-02-26 12:54:51 +0100 | <Athas> | tomsmeding: yes, but I'm just using a single exported function from Numeric.AD.Double. |

| 2025-02-26 12:54:33 +0100 | <tomsmeding> | Athas: aren't you doing reverse-then-forward in kmeans? i.e. your reverse mode is not actually on Doubles, but on dual numbers? |
| 2025-02-26 12:53:53 +0100 | <Athas> | Oh, this is interesting. I don't see tape_backPropagate when I use Numeric.AD.Double in my kmeans implementation, but I do see it when I use it for the dummy 'hello' benchmark. |
| 2025-02-26 12:53:45 +0100 | <tomsmeding> | well, I put a newline and an indent after the `:`, but otherwise, yes, that's exactly what I did |

| 2025-02-26 12:52:29 +0100 | <Athas> | And 'constraints: ad +ffi' in my cabal.project is enough? |

| 2025-02-26 12:51:50 +0100 | <tomsmeding> | it worked for me! |
| 2025-02-26 12:51:42 +0100 | <Athas> | I assume cabal's logic for recompiling dependencies on flag changes is sound, right? |
| 2025-02-26 12:51:19 +0100 | <Athas> | It does not. |
| 2025-02-26 12:50:53 +0100 | <tomsmeding> | that distinguishes between an ad +ffi and an ad -ffi build for me |
| 2025-02-26 12:50:21 +0100 | <tomsmeding> | Athas: if you `nm` your executable, does it reference `tape_backPropagate`? |
