 Robbie Buxton | * They have a rev | 23:56:25 |

 apyh | ah fair enough | 00:10:30 |
 SomeoneSerge (back on matrix) | step 1: torchWithCuda = pkgsCuda.....torch (we were supposed to be here now, but it got out of hand)
step 2: torchWithCuda = warn "..." pkgsCuda...
step 3: torchWithCuda = throw | 00:12:18 |
| SomeoneSerge (back on matrix) | and what we really want is late binding and incremental builds | 00:13:41 |
 connor (burnt/out) (UTC-8) | Why are you building for so many CUDA capabilities? I can’t really think of a reason you’d need that range in particular. | 01:59:14 |
| connor (burnt/out) (UTC-8) | Added to merge queue | 02:07:23 |

Why are you building for so many CUDA capabilities? I can’t really think of a reason you’d need that range in particular. 's a distributed ml training application that needs to run on everything from gtx 10xx gpus to modern data center GH/GB200s :/ | 03:27:37 |
| apyh | most common hardware is gonna be 30xx 40xx 50xx, h100, a100, b200 | 03:27:56 |
| apyh | though.. i could just see what pytorch precompiled wherls runs on and limit to that | 03:28:54 |
| apyh | should be fine | 03:28:56 |
| connor (burnt/out) (UTC-8) | Flash attention doesn’t support anything older than Ampere I thought | 03:29:07 |
| Robbie Buxton | V2 does | 03:29:19 |
| Robbie Buxton | V3 is hopper only | 03:29:24 |
| apyh | ya its only v3 iirc | 03:29:26 |
| Robbie Buxton | V4 (cute) is Blackwell | 03:29:33 |
| Robbie Buxton | But that’s a wip | 03:29:38 |
| apyh | and yeah fair enough I could drop fa for older gpus, ig i can provide cuda capabilities different per package | 03:30:06 |
| Robbie Buxton | Requires cutlass-dsl | 03:30:07 |
| connor (burnt/out) (UTC-8) | V2 doesn’t support older than Ampere per their readme, unless they forgot to update it | 03:30:25 |

V2 doesn’t support older than Ampere per their readme, unless they forgot to update it yeah makes sense then maybe I'll just drop and see if anyone complains lol | 03:30:43 |

V2 doesn’t support older than Ampere per their readme, unless they forgot to update it It’s not optimized but it runs | 03:30:46 |
| Robbie Buxton | V3 is busted | 03:30:54 |
| connor (burnt/out) (UTC-8) | So long as you have PTX it should be fine | 03:30:55 |
| connor (burnt/out) (UTC-8) | cries in Ada | 03:31:14 |
| connor (burnt/out) (UTC-8) | Robbie have you been following PyTorch Helion? Seems interesting (but boooooo Bazel build) | 03:32:07 |
| Robbie Buxton | Yeah seems cool, morach too! | 03:32:37 |
| Robbie Buxton | * Yeah seems cool, monarch too! | 03:32:47 |
| apyh | monarch looks sweeet | 03:32:52 |
| apyh | were any of you at pytorch conference? | 03:33:02 |
| apyh | shoulda asked when i was there lol | 03:33:08 |
