1. In [Measuring / Calculating Startup Time](#sec-measurements),I provide a
summary of how the startup time is identified and calculated.
2. I'm not sure exactly I understand
> Will the measurement methodology be the same for distributed training? For
> examples, we can measure the start-up time for the rank0?
The startup time is being measured for distributed training (logs only
created on `RANK = 0`)
3. I discuss in [Minimal Working Example](#minimal-working-example) a minimal example that can be used to measure
the startup times.
- This is using a library I've been working on,
[`ezpz`](https://github.com/saforem2/ezpz) that is designed to help
simplify the process of setting up / initializing distributed training
across many GPUs.
### Measuring / Calculating Startup Time {#sec-measurements}
- The startup timing was identified by parsing the logfiles from existing runs
and calculating the difference $\delta t = t_{1} - t_{0}$,
- $t_{0}$ is the time stamp at the _very_ beginning of the shell script
(defined [here](https://github.com/argonne-lcf/Megatron-DeepSpeed/blob/657bb3e312e793d7b503f475b59e44c1aee44205/ALCF/train-gpt3.sh#L3))
which then launches `mpiexec <mpi-args> python3 [...]`.
- $t_{0}$ appears in the logfile as:
```bash
Job started at: 2023-11-02-183323 on x3004c0s13b0n0
```
- $t_{1}$ is identified as the timestamp associated with the completion of
the first training step
- $t_{1}$ appears in the logfile as:
```bash
[2023-11-02 18:34:13,122] [INFO] [logging.py:96:log_dist] [Rank 0] step=0, skipped=0, lr=[0.0, 0.0], mom=[(0.9, 0.999), (0.9, 0.999)]
```
- Below is an example of the bash script use to parse the logfiles and identify these timestamps:
```bash
$ for f in $(tail -5 logfiles) ; do echo $f; cat $f | grep -E "Job started|step=0\," | uniq ; echo "\n" ; done

: Startup times on Perlmutter
:::
:::
## Minimal Working Example
- As for 3:
> If we need to report the startup time for the DL applications, do we need
> to collect measurements using the actual Aurora NRE workloads or some small
> benchmarking test cases? For example, we can try to recreate the typical
> start-up scenarios, like library imports, and measure those separately as
> shown below.
- I've been working on a library to help simplify this:
[{{< iconify tabler brand-github >}} `ezpz`](https://github.com/saforem2/ezpz)
[_Minimal library that handles the initialization of distributed training_]{.dim-text}
- [x] Working on Aurora, example:
- Setup / Install:
```bash
# launch job
$ qsub -q EarlyAppAccess -A Aurora_Deployment -l walltime=2:00:00 -l select=4 -I
# load frameworks
$ module use -a /soft/modulefiles ; module --ignore_cache load frameworks
$ module load frameworks/.2023.12.15.001
# install `ezpz`
$ git clone https://github.com/saforem2/ezpz
$ cd ezpz
$ mkdir -p venvs/aurora/2023.12.15.001
$ python3 -m venv venvs/aurora/2023.12.15.001 --system-site-packages
$ source venvs/aurora/2023.12.15.001/bin/activate
$ python3 -m pip install -e .
# print job info and define `launch` alias
$ source ezpz/src/ezpz/bin/savejobenv
