Notice: The reproducibility variables underlying each score are classified using an automated LLM-based pipeline, validated against a manually labeled dataset. LLM-based classification introduces uncertainty and potential bias; scores should be interpreted as estimates. Full accuracy metrics and methodology are described in Coakley et alK. L. Coakley, T.

Research Type Experimental Evaluated across a range of Transformer models, CATransformers consistently demonstrates the potential to reduce total carbon emissions by up to 30% while maintaining accuracy and latency. We further highlight its extensibility through a focused case study on multi-modal models. (Abstract) and 4 Evaluation (Section Title)

Pseudocode No The paper describes methods in prose and diagrams (e.g., Figure 2: Overview of the CATransformers framework) but does not include any explicitly labeled pseudocode or algorithm blocks.
Open Source Code Yes The source code of CATransformers is available at https://github.com/facebookresearch/CATransformers.
Open Datasets Yes For language models we use the MRPC task from the GLUE dataset [WSM+18] for semantic similarity detection, for vision models, the CIFAR-10 dataset [Kri09] for image classification; and for CLIP models, the MSCOCO dataset [LMB+15] for retrieval... and adopt Open CLIP s [IWW+21] Data Comp-1B [GIF+23] models for CLIP.
Dataset Splits Yes For language models we use the MRPC task from the GLUE dataset [WSM+18] for semantic similarity detection, for vision models, the CIFAR-10 dataset [Kri09] for image classification; and for CLIP models, the MSCOCO dataset [LMB+15] for retrieval.
Hardware Specification Yes Bayesian optimization is performed on a single node (8 V100 GPUs, 80 CPUs) over 100 trials... We further validate energy and latency predictions against real GPU hardware (V100, A100, H100) by modeling GPU-like architectures.
Software Dependencies No The paper mentions several software tools and frameworks used (e.g., Hugging Face, Open CLIP, Ax, BoTorch, Accelergy, Sunstone, ACT, Electricity Maps), but does not provide specific version numbers for these software dependencies as required for reproducible description.
Experiment Setup Yes Bayesian optimization is performed on a single node (8 V100 GPUs, 80 CPUs) over 100 trials, taking 5-20 hours depending on the model. Post-pruning training of Carbon CLIP uses 224 GPUs on the Meta CLIP-2.5B dataset [XXT+24], with a batch size of 128, learning rate of 5 10^4, and 2 distillation epochs... We evaluate different optimization modes under a 20 TOPS compute budget... When latency is not an optimization target, a maximum latency constraint of 50ms is enforced...
