Description
Dear maintainers,
Recently I attempted using the profiling workflow in the vidur project and collect profiling data on AWS EC2 instances. I experimented with the P5 48X which has 8X H100 connected using DGX with 8 GPUs for CodeLlama-34b-Instruct-hf. The code I used are vidur main branch and sarathi-serve vidur branch. However, the profiling results I got differ significantly from the ones in the provided data folder.
I have attached my collected data. I noticed several differences and potential issues.
- New profiled data uses flashinfer, while the reference uses flash_attention.
- New profiling data has additional columns for kv_cache_save.
Using the profiling data, vidur's prediction varies significantly from using the reference data. Could you please help me understand the correct profiling workflow?

Thank you for your help.

Research direction
Start with Vidur's profiling workflow and compare the attached New_H100_codellama_CodeLlama-34b-Instruct-hf_attention.csv with the reference data in the provided data folder. Check the reported flashinfer versus flash_attention entries and the additional kv_cache_save columns, then document the correct workflow and the source of the prediction differences.
