Summary:
Part of an effort to extract some important error logs (e.g. [#157996](https://github.com/pytorch/pytorch/pull/157996)) that was `tee`'ed to `stdout` and `stderr`.
The general idea is to:
- Duplicate the `tee`s on `stdout` and `stderr` to a separate file, `filtered_stdout.log` and `filtered_stderr.log`, respectively.
- In these files, as its name suggests, only log lines matching a customizable filter.
- Later on in another PR, append the contents of these files to the reply file.
Outline of changes in this PR:
- Enhance `TailLog` to be able to 1) stream to a file, and 2) only write when the line matches the passed filter.
- Add `filtered_stdout` and `filtered_stderr` to `LogsDest` and have `LogsSpecs` `reify` them.
- In `start_processes()` and `PContext`, add params `duplicate_stdout_filters` and `duplicate_stderr_filters` to filter and write the duplicated stream to the files above. When no filters are passed in, no duplicated streams are created.

# Context
This is an extension of #149334.
# This PR
Add support for NUMA bindings with Callable entrypoints, such as `do_train` instead of `/usr/local/bin/python`.
Most notably, we utilize a hack in order to force `Process.start()` to use custom NUMA bindings for each subprocess. Please search for `HACK:` in the code to see a description of the implementation we chose, and #160006 for discussion of alternatives and why this is necessary.
Other changes:
* Remove unnecessary `--preferred` option from all binding strategies. By default, Linux already allocates memory to the NUMA node local to the CPU which triggered the allocation. (See [MPOL_LOCAL](https://man7.org/linux/man-pages/man2/set_mempolicy.2.html).)
* Refactor so that the main API is `maybe_wrap_command_with_numa_bindings`, which computes bindings for a single rank at a time, rather than `maybe_wrap_with_numa_bindings` which computed bindings for all ranks at once. This allowed for more code sharing between `Callable` and `str` entrypoints.
# Test Plan
## Automated
`$ pytest test/test_numa_binding.py`
## Manual
Using [this benchmark,](https://gist.github.com/pdesupinski/bbe01ade455d86e989794f2c612e2d91), ran
```
$ PYTHONUNBUFFERED=1 LOGLEVEL=INFO perf stat -e ls_dmnd_fills_from_sys.dram_io_far,ls_dmnd_fills_from_sys.dram_io_near -- python -m torch.distributed.run --standalone --nproc-per-node=8 --numa-binding=node --run-path mlp_train.py 2>&1 | tee node_callable.txt && PYTHONUNBUFFERED=1 LOGLEVEL=INFO perf stat -e ls_dmnd_fills_from_sys.dram_io_far,ls_dmnd_fills_from_sys.dram_io_near -- python -u -m torch.distributed.run --standalone --nproc-per-node=8 --run-path mlp_train.py 2>&1 | tee none_callable.txt
```
and observed
* 6.6% remote memory accesses with 'node' bindings
* 11.6% remote without bindings
I also ran similar with `str` entrypoints as before just to be sure it's still working.
NOTE: [--run-path triggers the code to be run inside a `Callable`.](017259f9c6/torch/distributed/run.py (L870))

This reduces the default monitor_interval for torchelastic to 0.1s as testing shows negligble load for common use cases. Even at the extremes, 100k processes is only 45.4% cpu util of a single core.
Torchelastic monitor_interval only monitors the processes on a single worker so under typical loads even for huge jobs we expect ~8 subprocesses per machine with one per GPU.
As an external datapoint, Python's wait polls every 50usec-50ms (https://github.com/python/cpython/blob/main/Lib/subprocess.py#L2035).
## Motivation
This setting is used to control how frequently we poll for failed processes in elastic.
* For some jobs of note we run elastic 3 times per try so with the default timeout of 5 seconds we should save ~15 seconds per retry.
* @kiukchung's use case: Apparently this is annoying in notebooks etc since it adds delay to shutdown when testing things
## Results
This is measured in cores (100% is a single core under full load).
| monitor_interval (s) | nproc-per-node | CPU util (highest observed) |
| -------------------- | -------------- | --------------------------- |
| 1.0 | 10 | 0.2% |
| 0.1 | 1 | 0.4% |
| 0.1 | 10 | 0.4% |
| 0.01 | 10 | 0.9% |
| 0.001 | 10 | 4.0% |
| 0.1 | 100 | 0.5% |
| 0.1 | 1000 | 2.2% |
| 0.1 | 10000 | 15.7% |
| 0.1 | 100000 | 45.4% |
## Methodology
```sh
# run command
$ LOGLEVEL=INFO torchrun --nnodes 1 --nproc-per-node 10 --monitor-interval 0.1 ~/wait.py
# wait a few seconds for all processes to start and reach steady state and then run, wait ~30s or 3 prints and take the highest
$ top -b -d 10 -c | rg 'torchrun.*wait
```
wait.py
```py
import time
time.sleep(10*60)
```

Adds a ruff lint rule to ban raising raw exceptions. Most of these should at the very least be runtime exception, value errors, type errors or some other errors. There are hundreds of instance of these bad exception types already in the codebase, so I have noqa'd most of them. Hopefully this error code will get commiters to rethink what exception type they should raise when they submit a PR.
I also encourage people to gradually go and fix all the existing noqas that have been added so they can be removed overtime and our exception typing can be improved.

Summary:
Minor logging cleanup in distributed library
1. Don't use "f" formatted strings - address linter issues.
2. Nits: Make use of unused `e` (error) in a few logs.
3. Change info->debug as asked in issue #113545
4. Nit: rename log -> logger in a few files for consistency
5. Fix a linter error.
Test Plan:
1. Local build passes.
2. Linter is happy.

Summary:
Expose an option to users to specify name of the LogsSpec implementation to use.
- Has to be defined in entrypoints under `torchrun.logs_specs` group.
- Must implement LogsSpec defined in prior PR/diff.

Summary:
Pulling out logging parameters into a logging specs that can be overridden (follow-up changes on possible mechanism)
Why?
Right now the logging approach is quite rigid:
- Requires for log directory to exist and not be empty
- Will create tempdir otherwise,
- Creates subdir for a run
- creates subdir for each attempt
- creates files named as stdout.log, stderr.log, error.json
In some instances some of the users would like to customize the behavior including file names based on context. And we do have right now a mechanism to template multiplexed teed output prefix.
With current changes, users can create custom log spec that can use env variables to change the behavior.
Notes:
Made `LaunchConf.logs_specs` as an optional field that will be bound to `DefaultLogsSpecs` instance. There are large number of clients (code) that use the API directly without using torchrun API. For those cases, we have to explicitly pass LogSpecs implementation if we would like to override the implementation. For the regular torchrun users, we can use pluggable approach proposed in the follow up change.
Test Plan: CI + unit tests

Addresses issue https://github.com/pytorch/pytorch/issues/117383
The implementation exposes `--local-ranks-filter` which filters by rank which files we pass to `TailLog` (used in torchrun to determine which logs to output to stdout/stderr)
## Behavior
### with --tee
Currently --tee is implemented as --redirect to file, and streams file to console using `tail`. When --tee is specified, file logs will be unaffected and we will only filter the output to console.
### with --redirect
When --redirect is specified without --tee, nothing is logged to console, so we no-op.
### with neither
When neither --tee or --redirect are specified, torchrun uses empty string "" to indicate logging to console. We intercept this empty string, and redirect it to "/dev/null" to not print to console.
The api also allows a per-rank configuration for --tee and --redirect, and is also supported by this filter implementation.
## Usage
### without --tee

Pull Request resolved: https://github.com/pytorch/pytorch/pull/112953
Approved by: https://github.com/weifengpy
Summary:
Add an ability to customize log lines and addtional template like behavior to enrich log information.
Motivation:
a) Log stream processing/aggregation gains additional value when it includes information about the global rank. Extension to that is that it will be easier to map ranks to hosts from log stream information (less relevant at the moment)
b) Users can easily map the failure to the right rank without matching node rank offset+local rank.
Implementation
- BC change - keeps the logs line prefix as `[<role name><local rank>]:`
- Optional env variable TORCHELASTIC_LOG_LINE_HEADER that will be used as a prefix when specified and currently exposes `role_name`, `rank` and `local_rank` variables that will be bound when agent assigns the ranks.
Test Plan:

Given standalone generates args anyways, it seems like it would be more convenient if it explicitly used a random port by default instead of trying to use 29400.
That way users can directly go with `--standalone` instead of having to spell out `--rdzv-backend=c10d --rdzv-endpoint=localhost:0`

Summary:
Calls to this function without an argument will get a stack trace at
import time. This is expensive, we can just skip it by passing in a value.
Test Plan: Wait for tests

Preferring dash over underscore in command-line options. Add `--command-arg-name` to the argument parser. The old arguments with underscores `--command_arg_name` are kept for backward compatibility.
Both dashes and underscores are used in the PyTorch codebase. Some argument parsers only have dashes or only have underscores in arguments. For example, the `torchrun` utility for distributed training only accepts underscore arguments (e.g., `--master_port`). The dashes are more common in other command-line tools. And it looks to be the default choice in the Python standard library:
`argparse.BooleanOptionalAction`: 4a9dff0e5a/Lib/argparse.py (L893-L895)
```python
class BooleanOptionalAction(Action):
def __init__(...):
if option_string.startswith('--'):
option_string = '--no-' + option_string[2:]
_option_strings.append(option_string)
```
It adds `--no-argname`, not `--no_argname`. Also typing `_` need to press the shift or the caps-lock key than `-`.
