Hello, WorldThis is officially the first post! How exciting!
It ‘twas the morning of July 18, 2019 as I was working on this site; just polishing up a few tidbits, when my 2012 Macbook Pro became quite warm and decided to poweroff, never to return again. About 30 minutes had past while I aimlessly troubleshot, but ultimately I found myself on Apple’s support site scheduling an appointment to have my laptop serviced.
If you searched for “promptfoo” and landed here, you might be wondering: is this the official promptfoo site? Are PromptFu and promptfoo the same thing? Here’s the clear answer.
If you’ve been searching for promptfoo, you’ve found the right place. This is a comprehensive guide to the promptfoo framework — what it is, what it does, and how to get started with AI prompt testing.

Rsync between hosts, using a jump host’s ssh keys as the intermediary:
cat raw.old.new.list | awk '{ print( " ssh " $1 " \x27 " "rsync -avP /app/users " $2 ":/app \x27 ") }'
# and to run it...
cat raw.old.new.list | awk '{ system( " ssh -A " $1 " \x27 " "rsync -avP /app/users " $2 ":/app \x27 ") }'
Summary
taskset is used to affine an application to a specific set of CPU cores; usally taking into account NUMA architecture.
CPU/memory affinity can improve performance of workloads that are performance-critical and/or that may be network-heavy.
Affining closely related applications on the same NUMA node can improve memory access latencies, and newtork-heavy workloads can take advantage of affining applications by scheduling network I/O on the same NUMA node as the NIC card to reduce the latency between the CPU and PCIe.
