✨ NAME ✨

oshdiff — bestie, the whole name is just oshdiff, that's it, that's the vibe 💅

🦋 DESCRIPTION 🦋

okay so let's get into it 🫶 — here's how you call this thing:

usage: oshdiff [options] options:

and here are ALL the --osh- flags, no skipping, I would never 🙈:

• --osh-memory — prints the amount of memory used at peak plus a stacktrace of that max memory use 📈
• --osh-time — prints how much time gets spent in certain functions ⏱️
• --osh-time-percent — same deal, but as a percentage 💯
• --osh-time-chop 0.0 — only prints functions whose percent time is greater than the value you give it (like, e.g. --osh-time-chop=2) ✂️
• --osh-time-with-filename — adds the file name onto the function name in the profile output 📁
• --osh-signal — catches signals and prints a stacktrace 🚨
• --osh-fpe — enables floating-point exceptions 🌊
• --osh-silent — suppresses all output 🤫
• --osh-pool — uses memory pooling 🏊
• --osh-self-send value — controls the self send threshold 🎚️
• --osh-mpi-ranks-per-node value — mpi ranks per node (for CUDA+MPI) 👑💻

then, for actually running a diff, you call it like:

usage: oshdiff [options] gold.osh result.osh

or: oshdiff [-help]
       (usage)

and the options for that are:

• -help — prints this summary and exits 👋
• -tolerance <$val> — overrides the default tolerance of 1.0E-6 🎯
• -Floor <$val> — overrides the default floor tolerance of 0.0 🧊
• -superset — allows the result to have more arrays than gold ➕

not me noticing this whole block shows up a second time below, literally identical, same energy, same facts, so here it is again fr fr 💖

usage: oshdiff [options] gold.osh result.osh

or: oshdiff [-help]
       (usage)

• -help — prints this summary and exits 👋
• -tolerance <$val> — overrides the default tolerance of 1.0E-6 🎯
• -Floor <$val> — overrides the default floor tolerance of 0.0 🧊
• -superset — allows the result to have more arrays than gold ➕
