Basic ARTIQ Python
|

^^^^^^^^^^^^^^^^^^
|

|
||||
Basic Python features can broadly be used inside kernels without further compunctions. This includes loops (``for`` / ``while`` / ``break`` / ``continue``), conditionals (``if``, ``else``, ``elif``), functions, exceptions, ``try`` / ``except`` / ``else`` blocks, and statically typed variables of any supported types.

Kernel code can call host functions without any additional ceremony. However, such functions are assumed to return ``None``, and if a value other than ``None`` is returned, an exception is raised. To call a host function returning a value other than ``None`` its return type must be annotated, using the standard Python syntax, e.g.: ::

The core device contains some flash storage space which is used to store configuration data. It is one sector (typically 64 kB) large and organized as a list of key-value records, accessible by using ``artiq_coremgmt`` (see :ref:`core-device-management-tool`). The core device IP and MAC addresses, as well as, if present, the startup and/or idle kernels (see :ref:`miscellaneous_config_core_device`) are stored here.

As of ARTIQ 8, it is now possible for Kasli and Kasli-SoC configurations to enable WRPLL -- a clock recovery method using `DDMTD <http://white-rabbit.web.cern.ch/documents/DDMTD_for_Sub-ns_Synchronization.pdf>`_ and Si549 oscillators -- both to lock the main RTIO clock and (in DRTIO configurations) to lock satellites to master. This is set by the ``enable_wrpll`` option in the JSON description file. Because WRPLL requires slightly different gateware and firmware, it is necessary to re-flash devices to enable or disable it in extant systems. If you would like to obtain the firmware for a different WRPLL setting through ``awfs_client``, write to the helpdesk@ email.

If phase noise performance is the priority, it is recommended to use ``ext0_synth0_125to125`` over other ``ext0`` options, as this bypasses the (noisy) MMCM.

ARTIQ Releases
|

##############
|
||||
|

ARTIQ follows a rolling release model, with beta, stable, and legacy channels. Different releases are saved as different branches on the M-Labs `ARTIQ repository <https://github.com/m-labs/artiq>`_. The ``master`` branch represents the beta version, where at any time the next stable release of ARTIQ is currently in development. This branch is unstable and does not yet guarantee reliability or consistency, but may also already offer new features and improvements; see the `beta release notes <https://github.com/m-labs/artiq/blob/master/RELEASE_NOTES.rst>`_ for the most up-to-date information. The ``release-[number]`` branches represent stable releases, of which the most recent is considered the current stable version, and the second-most recent the current legacy version.

To install the current stable version of ARTIQ, consult the *current* `Installing ARTIQ <https://m-labs.hk/artiq/manual/installing.html>`_ page. To install beta or legacy versions, consult the same page in their respective manuals. Instructions given in pre-legacy versions of the manual may or may not install their corresponding ARTIQ systems, and may or may not currently be supported (e.g. M-Labs does not host older ARTIQ versions for Conda, and Conda support will probably eventually be removed entirely). Regardless, all out-of-date versions remain available as complete source code on the repository.

Certain peripheral cards with onboard FPGAs of their own (e.g. Shuttler) can be configured as satellites in a DRTIO setting, allowing them to run their own subkernels and make use of DDMA. In these cases, the EEM connection to the core device is used for DRTIO communication (DRTIO-over-EEM).

As with other configuration changes (e.g. adding new hardware), if you are in possession of a non-distributed ARTIQ system and you'd like to expand it into a DRTIO setup, it's easily possible to do so, but you need to be sure that both master and satellite are (re)flashed with this in mind. As usual, if you obtained your hardware from M-Labs, you will normally be supplied with all the binaries you need, through ``awfs_client`` or otherwise.

Do not confuse the DRTIO *master device* (used to mean the central controlling core device of a distributed system) with the *ARTIQ master* (the central piece of software of ARTIQ's management system, which interacts with ``artiq_client`` and the dashboard.) ``artiq_run`` can be used to run experiments on DRTIO systems just as easily as non-distributed ones, and the ARTIQ master interacts with the central core device regardless of whether it's configured as a DRTIO master or standalone.
