Release notes
=============
ARTIQ-4
-------
2018-01-11 11:38:06 +08:00
4.0
***
2017-09-30 00:29:54 +08:00
2018-01-11 11:38:06 +08:00
* RTIO outputs use a new architecture called Scalable Event Dispatcher (SED),
which allows building systems with large number of RTIO channels more
efficiently.
From the user perspective, collision errors become asynchronous, and non-
monotonic timestamps on any combination of channels are generally allowed
(instead of producing sequence errors).
RTIO inputs are not affected.
* The DDS channel number for the NIST CLOCK target has changed.
* The dashboard configuration files are now stored one-per-master, keyed by the
server address argument and the notify port.
* The master now has a ``--name`` argument. If given, the dashboard is labelled
with this name rather than the server address.
* ``artiq_flash -m/--adapter`` has been changed to ``artiq_flash -V/--variant``.
2018-01-22 18:25:10 +08:00
* ``kc705_dds`` has been renamed ``kc705``.
* the ``-H/--hw-adapter`` option of ``kc705`` has ben renamed ``-V/--variant``.
* SPI masters have been switched from misoc-spi to misoc-spi2. This affects
all out-of-tree RTIO core device drivers using those buses. See the various
2018-03-24 22:20:04 +08:00
commits on e.g. the ``ad53xx`` driver for an example how to port from the old
to the new bus.
2018-03-24 22:20:04 +08:00
* The ``ad5360`` coredevice driver has been renamed to ``ad53xx`` and the API
has changed to better support Zotino.

3.2
***
2017-12-27 10:52:41 +08:00
* To accommodate larger runtimes, the flash layout as changed. As a result, the
contents of the flash storage will be lost when upgrading. Set the values back
(IP, MAC address, startup kernel, etc.) after the upgrade.

***
2016-09-04 23:32:09 +08:00
2017-09-30 01:10:10 +08:00
* The ``--embed`` option of applets is replaced with the environment variable
2017-05-22 19:05:39 +08:00
``ARTIQ_APPLET_EMBED``. The GUI sets this enviroment variable itself and the
user simply needs to remove the ``--embed`` argument.
2017-09-30 01:10:10 +08:00
* ``EnvExperiment``'s ``prepare`` calls ``prepare`` for all its children.
2017-05-22 19:05:39 +08:00
* Dynamic ``__getattr__``'s returning RPC target methods are not supported anymore.
Controller driver classes must define all their methods intended for RPC as
members.
* Datasets requested by experiments are by default archived into their HDF5
output. If this behavior is undesirable, turn it off by passing
``archive=False`` to ``get_dataset``.
2016-11-21 23:51:39 +08:00
* ``seconds_to_mu`` and ``mu_to_seconds`` have become methods of the core
device driver (use e.g. ``self.core.seconds_to_mu()``).
* AD9858 DDSes and NIST QC1 hardware are no longer supported.
* The DDS class names and setup options have changed, this requires an update of
the device database.
* ``int(a, width=b)`` has been removed. Use ``int32(a)`` and ``int64(a)``.
2017-09-30 01:10:10 +08:00
* The KC705 gateware target has been renamed ``kc705_dds``.
* ``artiq.coredevice.comm_tcp`` has been renamed ``artiq.coredevice.comm_kernel``,
and ``Comm`` has been renamed ``CommKernel``.
* The "collision" and "busy" RTIO errors are reported through the log instead of
raising exceptions.
* Results are still saved when ``analyze`` raises an exception.
2017-05-15 17:21:54 +08:00
* ``LinearScan`` and ``RandomScan`` have been consolidated into RangeScan.
* The Pipistrello is no longer supported. For a low-cost ARTIQ setup, use either
ARTIQ 2.x with Pipistrello, or the future ARTIQ 4.x with Kasli. Note that the
Pipistrello board has also been discontinued by the manufacturer but its design
files are freely available.
* The device database is now generated by an executable Python script. To migrate
an existing database, add ``device_db = `` at the beginning, and replace any PYON
identifiers (``true``, ``null``, ...) with their Python equivalents
2017-05-22 19:05:39 +08:00
(``True``, ``None`` ...).
* Controllers are now named ``aqctl_XXX`` instead of ``XXX_controller``.
2017-09-30 01:10:10 +08:00
* In the device database, the ``comm`` device has been folded into the ``core`` device.
Move the "host" argument into the ``core`` device, and remove the ``comm`` device.
* The core device log now contains important information about events such as
RTIO collisions. A new controller ``aqctl_corelog`` must be running to forward
those logs to the master. See the example device databases to see how to
instantiate this controller. Using ``artiq_session`` ensures that a controller
manager is running simultaneously with the master.
* Experiments scheduled with the "flush pipeline" option now proceed when there
are lower-priority experiments in the pipeline. Only experiments at the current
(or higher) priority level are flushed.
* The PDQ(2/3) driver has been removed and is now being maintained out-of tree
at https://github.com/m-labs/pdq. All SPI/USB driver layers, Mediator,
CompoundPDQ and examples/documentation has been moved.
* The master now rotates log files at midnight, rather than based on log size.
2017-09-30 01:10:10 +08:00
* The results keys ``start_time`` and ``run_time`` are now stored as doubles of UNIX time,
2017-08-03 19:56:15 +08:00
rather than ints. The file names are still based on local time.
2017-09-29 23:14:21 +08:00
* Packages are no longer available for 32-bit Windows.

2.0rc1
******
* The format of the influxdb pattern file is simplified. The procedure to
edit patterns is also changed to modifying the pattern file and calling:
``artiq_rpctool.py ::1 3248 call scan_patterns`` (or restarting the bridge)
The patterns can be converted to the new format using this code snippet::
from artiq.protocols import pyon
patterns = pyon.load_file("influxdb_patterns.pyon")
for p in patterns:
print(p)
2016-04-05 13:59:58 +08:00
* The "GUI" has been renamed the "dashboard".
* When flashing NIST boards, use "-m nist_qcX" or "-m nist_clock" instead of
just "-m qcX" or "-m clock" (#290).
* Applet command lines now use templates (e.g. $python) instead of formats
(e.g. {python}).
* On Windows, GUI applications no longer open a console. For debugging
purposes, the console messages can still be displayed by running the GUI
applications this way::
python3.5 -m artiq.frontend.artiq_browser
python3.5 -m artiq.frontend.artiq_dashboard
(you may need to replace python3.5 with python)
Please always include the console output when reporting a GUI crash.
* The result folders are formatted "%Y-%m-%d/%H instead of "%Y-%m-%d/%H-%M".
(i.e. grouping by day and then by hour, instead of by day and then by minute)
2016-04-16 19:31:07 +08:00
* The ``parent`` keyword argument of ``HasEnvironment`` (and ``EnvExperiment``)
has been replaced. Pass the parent as first argument instead.
* During experiment examination (and a fortiori repository scan), the values of
all arguments are set to ``None`` regardless of any default values supplied.
* In the dashboard's experiment windows, partial or full argument recomputation
takes into account the repository revision field.
* By default, ``NumberValue`` and ``Scannable`` infer the scale from the unit
for common units.
* By default, artiq_client keeps the current persist flag on the master.
* GUI state files for the browser and the dashboard are stores in "standard"
locations for each operating system. Those are
``~/.config/artiq/2/artiq_*.pyon`` on Linux and
``C:\Users\<username>\AppData\Local\m-labs\artiq\2\artiq_*.pyon`` on
Windows 7.
* The position of the time cursor is kept across experiments and RTIO resets
are manual and explicit (inter-experiment seamless handover).
* All integers manipulated by kernels are numpy integers (numpy.int32,
numpy.int64). If you pass an integer as a RPC argument, the target function
receives a numpy type.

1.0rc3
******
2016-04-05 17:21:51 +08:00
* The HDF5 format has changed.
* The datasets are located in the HDF5 subgroup ``datasets``.
2016-04-05 18:09:30 +08:00
* Datasets are now stored without additional type conversions and annotations
from ARTIQ, trusting that h5py maps and converts types between HDF5 and
python/numpy "as expected".
* NumberValue now returns an integer if ``ndecimals`` = 0, ``scale`` = 1 and
``step`` is integer.
2016-03-31 16:05:41 +08:00
1.0rc2
******
* The CPU speed in the pipistrello gateware has been reduced from 83 1/3 MHz to
75 MHz. This will reduce the achievable sustained pulse rate and latency
accordingly. ISE was intermittently failing to meet timing (#341).
* set_dataset in broadcast mode no longer returns a Notifier. Mutating datasets
should be done with mutate_dataset instead (#345).
2016-03-19 07:12:20 +08:00
1.0rc1
******
2016-01-29 12:55:03 +08:00
* Experiments (your code) should use ``from artiq.experiment import *``
(and not ``from artiq import *`` as previously)
* Core device flash storage has moved due to increased runtime size.
This requires reflashing the runtime and the flash storage filesystem image
2016-01-31 05:50:15 +08:00
or erase and rewrite its entries.
* ``RTIOCollisionError`` has been renamed to ``RTIOCollision``
* the new API for DDS batches is::
2016-03-19 05:55:39 +08:00
with self.core_dds.batch:
...
with ``core_dds`` a device of type ``artiq.coredevice.dds.CoreDDS``.
The dds_bus device should not be used anymore.
* LinearScan now supports scanning from high to low. Accordingly,
2016-03-19 07:12:20 +08:00
its arguments ``min/max`` have been renamed to ``start/stop`` respectively.
Same for RandomScan (even though there direction matters little).
