CONTRIBUTING.markdown

+Contributing to The Project
+===========================
+
+The following is a set of guidelines for contributing to this project. These
+are guidelines, not rules, so use your best judgement and feel free to propose
+changes.
+
+## Commit Messages Styleguide
+
+- use present tense, imperative mood
+- reference issues and merge requests
+- you can use [Gitlab Flavored Markdown](https://docs.gitlab.com/ee/user/markdown.html)
+
+If you want some help, here is a commit template that you can add to your git
+configuration. Save it to a `my-commit-template.txt` file and use `git config
+commit.template my-config-template.txt` to use it automatically.
+
+```
+# [type] If applied, this commit will...    ---->|
+
+
+# Why this change
+
+# Links or keys to tickets and others
+# --- COMMIT END ---
+# Type can be 
+#    feature
+#    fix (bug fix)
+#    doc (changes to documentation)
+#    style (formatting, missing semi colons, etc; no code change)
+#    refactor (refactoring production code)
+#    test (adding missing tests, refactoring tests; no production code change)
+# --------------------
+# Remember to
+#    Separate subject from body with a blank line
+#    Limit the subject line to 50 characters
+#    Capitalize the subject line
+#    Do not end the subject line with a period
+#    Use the imperative mood in the subject line
+#    Wrap the body at 72 characters
+#    Use the body to explain what and why vs. how
+#    Can use multiple lines with "-" for bullet points in body
+# --------------------
+```
+

+Welcome to NRM's documentation!
+===============================
+
+If you know about NRM and are just looking to get it to run on your
+application, please visit the :doc:`quickstart <quickstart>` guide.
+
+This documentation is technical. For a high-level overview of NRM, please
+refer to the Argo website_.
+
+The Node Resource Manager(NRM) is a node-local userspace client-server daemon
+for managing your scientific applications. It runs the various tasks that
+compose an application in resource-constrained slices, monitors
+performance, power use and application progress, and arbitrates resources at
+the node level, among which CPU Cores, NUMA Nodes, and Power budgets.
+
+There are two user software components shipped with NRM itself: the `nrm`
+command-line client and the `nrmd` daemon. Additionally, NRM ships with the
+`libnrm` application instrumentation library, to be used for progress
+monitoring. The following diagram describes this architecture:
+
+ .. image:: nrm.svg
+
+Note that the container runtime used by NRM to allocate slices is a
+system-installed dependency, regardless of whether Argo NodeOS or Singularity is used.
+
+The :doc:`quickstart <quickstart>` guide describes the use of `nrm` and `nrmd`.
+An important part of running tasks with `nrm` is the application :doc:`manifest
+<manifest>`, which you probably want to read about too.  Finally, please refer to the :doc:`libnrm <libnrm>` guide for
+application istrumentation.

+Libnrm
+======
+
+.. highlight:: bash
+
+Welcome to the libnrm guide. This document will help you in your use of the
+C/C++ and Fortran interface for NRM.
+
+Install
+=======
+
+The libnrm code can be installed for source::
+
+ git clone https://xgitlab.cels.anl.gov/argo/libnrm.git
+ cd libnrm
+ ./autogen.sh
+ ./configure
+ make && make install
+
+API
+===
+
+**nrm_ctxt_create(void)**
+
+This function creates a context and returns it.
+
+**nrm_init(struct nrm_context *, const char *)**
+
+This funciton starts the connection with NRM and gives all the application's
+communications a label.
+
+**`nrm_send_progress(struct nrm_context *, unsigned long progress)**
+
+This funciton sends the progress of the application to NRM.
+
+**nrm_fini(struct nrm_context *)**
+
+This function close the connection to NRM.
+
+**nrm_ctxt_delete(struct nrm_context *)**
+
+This functions deletes the NRM context.
+
+Using libnrm in your C/ C++ application
+=======================================
+.. highlight:: C
+
+The best way to understand how to make your application report progress to NRM
+is to use an example::
+
+ # include <stdio.h>
+
+ int main()
+ {
+   int i;
+
+   printf("hello\n")
+
+   for (i=1; j<4; i++){
+     printf("number %i\n",i);
+   }
+
+   printf("done!");
+   return 0;
+ }
+
+To make this code report progress to NRM, we need to:
+
+- include the library in the same way you include your other dependencies,
+- declare a nrm_context structure,
+- initialize your NRM context,
+- report progress to NRM at one point in your code,
+- close the connection and delete your NRM context,
+
+using the functions from the API. We end up with something like this::
+
+ # include <stdio.h>
+ # include <nrm.h>
+
+ int main()
+ {
+   int i;
+   struct nrm_context context;
+
+   printf("hello\n")
+   nrm_init(&context, "example");
+
+   for (i=1; j<4; i++){
+     printf("number %i\n",i);
+     nrm_send_progress(&context, 1);
+   }
+
+   printf("done!");
+   nrm_fini(&context);
+   return 0;
+ }
+
+Using libnrm in your Fortran application
+========================================
+.. highlight:: Fortran
+
+The same thing can be done with a Fortran application, using the Fortran
+interface of this library. Let's take a similar example::
+
+ implicit none
+
+ integer i
+
+ print*, "hello"
+
+ do i=1, 4
+   print*, "number", i
+ end do
+
+ print*, "done!"
+
+The functions in the Fortran interface are similar to the ones from the C API,
+only with a `f_` in front.
+To talk to NRM, the code becomes::
+
+ implicit none
+
+ include 'f_nrm.h'
+ include(kind=NRM_PTR) context
+
+ integer rc, i
+
+ print*, "hello"
+ rc = f_nrm_ctxt_create(context);
+ rc = f_nrm_init(context, 'example', len('example'))
+
+ do i=1, 4
+   print*, "number", i
+   progress = 1.0
+   rc = f_nrm_send_progress(context, progress)
+ end do
+
+ print*, "done!"
+ rc = f_nrm_fini(context)
+ rc = f_nrm_ctxt_delete(context)

+
+NodeOS
+~~~~~~
+
+For NodeOScontainer usage, you need to install our container piece
+on the system. On a production platform, this should be done by a sysadmin. On
+a development platform, this can be acheived with::
+
+ git clone https://xgitlab.cels.anl.gov/argo/containers.git

+
+NRM
+---
+
+The NRM core components (the `nrmd` daemon and `nrm` client) can be installed
+in multiple ways:
+
+using Spack
+~~~~~~~~~~~
+
+ spack install nrm
+
+using Nix
+~~~~~~~~~
+
+NRM has a Nix package in our local package repository::
+
+ nix-env -f "https://xgitlab.cels.anl.gov/argo/argopkgs/-/archive/master/argopkgs-master.tar.gz" -iA nrm
+
+using Pip
+~~~~~~~~~
+
+You should be able to get NRM and its dependencies on any machine with::
+
+ pip install git+https://xgitlab.cels.anl.gov/argo/nrm.git
+
+And entering the resulting virtual environment with `pipenv shell`.
+
+Setup: Launching the `nrmd` daemon
+==================================
+
+NRM's behavior is controlled by the `nrmd` userspace daemon.  The `nrmd` daemon
+should be launched by the application framework in the background and manages
+the resource arbitration on the machine.
+
+The daemon is launched via `nrmd` and logs its output to `/tmp/nrm_log` by
+default.
+
+`nrm` command-line options
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The `nrm` daemon is mainly configured
+through its command-line options.::
+
+  usage: nrmd [-h] [-c FILE] [-d] [-v] [--nrm_log NRM_LOG] [--hwloc HWLOC]
+              [--argo_nodeos_config ARGO_NODEOS_CONFIG] [--perf PERF]
+              [--pmpi_lib PMPI_LIB] [--argo_perf_wrapper ARGO_PERF_WRAPPER]
+              [--singularity SINGULARITY]
+              [--container-runtime {nodeos,singularity}]
+
+  optional arguments:
+    -h, --help            show this help message and exit
+    -c FILE, --configuration FILE
+                          Specify a config json-formatted config file to
+                          override any of the available CLI options. If an
+                          option is actually provided on the command-line, it
+                          overrides its corresponding value from the
+                          configuration file.
+    -d, --print_defaults  Print the default configuration file.
+    -v, --verbose         increase output verbosity
+    --nrm_log NRM_LOG     Main log file. Override default with the NRM_LOG
+                          environment variable
+    --hwloc HWLOC         Path to the hwloc to use. This path can be relative
+                          and makes uses of the $PATH if necessary. Override
+                          default with the HWLOC environment variable.
+    --argo_nodeos_config ARGO_NODEOS_CONFIG
+                          Path to the argo_nodeos_config to use. This path can
+                          be relative and makes uses of the $PATH if necessary.
+                          Override default with the ARGO_NODEOS_CONFIG
+                          environment variable.
+    --perf PERF           Path to the linux perf tool to use. This path can be
+                          relative and makes uses of the $PATH if necessary.
+                          Override default with the PERF environment variable.
+    --pmpi_lib PMPI_LIB   Path to the libnrm PMPI library used for the power
+                          policy. Override default with the PMPI environment
+                          variable.
+    --argo_perf_wrapper ARGO_PERF_WRAPPER
+                          Path to the linux perf tool to use. This path can be
+                          relative and makes uses of the $PATH if necessary.
+                          Override default with the PERFWRAPPER environment
+                          variable.
+    --singularity SINGULARITY
+                          Path to the singularity command. Override default with
+                          the SINGULARITY environment variable.
+    --container-runtime {nodeos,singularity}
+                          Choice of container runtime. Override default with the
+                          ARGO_CONTAINER_RUNTIME environment variable.
+
+Running jobs using `nrm`
+========================
+
+Tasks are configured using a JSON file called a manifest and started using the `nrm`
+command-line utility. Here's an example manifest that allocates two CPUS and
+enables application progress monitoring with a one second rate limit.::
+
+  name: basic
+  version: 0.0.1
+  app:
+    container:
+      cpus: 2
+      mems: 1
+    perfwrapper: true
+    monitoring:
+      ratelimit: 1000000000
+
+This manifest can be used in the following way to launch a command::
+
+ $ nrm run /path/to/manifest.yaml echo "foobar"
+ foobar
+ INFO:nrm:process ended: msg_up_rpc_rep_process_exit(api=u'up_rpc_rep', container_uuid=u'b54f12ed-6418-4b32-b6ab-2dda7503a1c8', status=u'0', type=u'process_exit')
+ INFO:nrm:command ended: msg_up_rpc_rep_process_exit(api=u'up_rpc_rep', container_uuid=u'b54f12ed-6418-4b32-b6ab-2dda7503a1c8', status=u'0', type=u'process_exit')
+
+You have run your first nrm-enabled command. See the :doc:`manifest
+guide <manifest>` for an in-depth description of the manifest file format.
+
+`nrm` command-line options
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The `nrm` command-line client can be used for a number of operations::
+
+  usage: nrm [-h] [-v] {run,kill,list,listen,setpower} ...
+
+  positional arguments:
+    {run,kill,list,listen,setpower}
+
+  optional arguments:
+    -h, --help            show this help message and exit
+    -v, --verbose         verbose logging information
+
+Start containerized tasks, using a container specification we refer to as an application :doc:`manifest <manifest>`::
+
+  usage: nrm run [-h] [-u [UCONTAINERNAME]] manifest command ...
+
+  positional arguments:
+    manifest              manifest file to apply
+    command               command to execute
+    args                  command arguments
+
+  optional arguments:
+    -h, --help            show this help message and exit
+    -u [UCONTAINERNAME], --ucontainername [UCONTAINERNAME]
+                          user-specified name for container used to attach
+                          proceses
+
+Listen for performance and power data::
+
+  usage: nrm listen [-h] [-u UUID] [-f FILTER]
+
+  optional arguments:
+    -h, --help            show this help message and exit
+    -u UUID, --uuid UUID  container uuid to listen for
+    -f FILTER, --filter FILTER
+                          type of message to filter and prettyprint, in
+                          {power,performance}
+
+List running tasks::
+
+  usage: nrm list [-h]
+
+  optional arguments:
+    -h, --help  show this help message and exit
+
+Kill tasks::
+
+  usage: nrm kill [-h] uuid
+
+  positional arguments:
+    uuid        uuid of the container
+
+  optional arguments:
+    -h, --help  show this help message and exit
+
+Set a node power target::
+
+  usage: nrm setpower [-h] [-f] limit
+
+  positional arguments:
+    limit         set new power limit
+
+  optional arguments:
+    -h, --help    show this help message and exit
+    -f, --follow  listen for power changes
