flexgen

Benchmark FlexGen

NOTE: This benchmark uses dummy weights by default for faster experiments. It is expected if you see randomly generated garbled characters, but the throughput and latency numbers should be correct.

Mount SSD

The following commands use ~/flexgen_offload_dir as the offloading folder by default. To get the best performance, it is recommonded to mount this folder on a fast SSD. If you use AWS or GCP instances with local SSDs, you can use mount_nvme_aws.sh or mount_nvme_gcp.sh to mount the local SSDs.
