"""Do standard clsim processing up to the I3Photon level.
These photons still need to be converted to I3MCPEs to be usable
for further steps in the standard IceCube MC processing chain.
Reads its particles from an I3MCTree and writes an I3PhotonSeriesMap.
All available OpenCL GPUs (and optionally CPUs) will
be used. This will take over your entire machine,
so make sure to configure your batch jobs correctly
when using this on a cluster.
When using nVidia cards, you can set the
CUDA_VISIBLE_DEVICES environment variable to
limit GPU visibility. A setting of
CUDA_VISIBLE_DEVICES="0,3" would only use cards
#0 and #3 and ignore cards #1 and #2. In case you are
using a batch system, chances are this variable is already
set. Unfortunately, there is no corresponding setting
for the AMD driver.
This segment assumes that MMC has been applied to the
I3MCTree and that MMC was *NOT* run using the "-recc" option.
:param UseCPUs:
Turn this on to also use CPU-based devices.
(This may potentially slow down photon generation, which
is also done on the CPU in parallel.)
:param UseGPUs:
Turn this off to not use GPU-based devices.
This may be useful if your GPU is used for display
purposes and you don't want it to slow down.
:param UseOnlyDeviceNumber:
Use only a single device number, even if there is more than
one device found matching the required description. The numbering
starts at 0.
:param MCTreeName:
The name of the I3MCTree containing the particles to propagate.
:param OutputMCTreeName:
A copy of the (possibly sliced) MCTree will be stored as this name.
:param FlasherInfoVectName:
Set this to the name of I3FlasherInfoVect objects in the frame to
enable flasher simulation. The module will read I3FlasherInfoVect objects
and generate photons according to assumed parameterizations.
:param FlasherPulseSeriesName:
Set this to the name of an I3CLSimFlasherPulseSeries object in the frame to
enable flasher/Standard Candle simulation.
This cannot be used at the same time as FlasherInfoVectName.
(I3CLSimFlasherPulseSeries objects are clsim's internal flasher
representation, if "FlasherInfoVectName" is used, the I3FlasherInfoVect
objects are converted to I3CLSimFlasherPulseSeries objects.)
:param MMCTrackListName:
Only used if *ChopMuons* is active. Set it to the name
of the I3MMCTrackList object that contains additional
muon energy loss information.
:param ParallelEvents:
clsim will work on a couple of events in parallel in order
not to starve the GPU. Setting this too high will result
in excessive memory usage (all your frames have to be cached
in RAM). Setting it too low may impact simulation performance.
The optimal value depends on your energy distribution/particle type.
:param RandomService:
Set this to an instance of a I3RandomService. Alternatively,
you can specify the name of a configured I3RandomServiceFactory
added to I3Tray using tray.AddService(). If you don't configure
this, the default I3RandomServiceFactory will be used.
:param MediumProperties:
Set this either to a directory containing a PPC-compatible
ice description (icemodel.dat, icemodel.par and cfg.txt) or
to a photonics ice table file. PPC-compatible ice files should
generally lead to faster execution times on GPUs since it involves
less interpolation between table entries (the PPC ice-specification
is parametric w.r.t. wavelength, whereas the photonics specification
is not).
:param Area:
Geometric area of the sensor. If None, use the area of an IceCube DOM
:param WavelengthAcceptance:
Quantum efficiency of the sensor, relative to the geometric area. If
None, use the IceCube DOM (standard QE)
:param AngularAcceptance:
Efficiency as a function of polar angle, relative to the geometric area.
If None, use the IceCube angular efficiency, assuming hole ice.
:param UseGeant4:
Enabling this setting will disable all cascade and muon light yield
parameterizations. All particles will sent to Geant4 for a full
simulation. This does **not** apply to muons that do have a length
assigned. These are assumed to have been generated by MMC and
their light is generated according to the usual parameterization.
:param CrossoverEnergyEM:
If set it defines the crossover energy between full Geant4 simulations and
light yield parameterizations for electro magnetic cascades. This only works
when UseGeant4 is set to true. It works in conjunction with CrossoverEnergyHadron.
If one of both is set to a positiv value greater 0 (GeV), the hybrid simulation
is used.
If CrossoverEnergyEM is set to None while CrossoverEnergyHadron is set so
hybrid mode is working, GEANT4 is used for EM cascades.
If CrossoverEnergyEM is set to 0 (GeV) while CrossoverEnergyHadron is set
so hybrid mode is working, leptons and EM cascades will use parameterizations
for the whole energy range.
:param CrossoverEnergyHadron:
If set it defines the crossover energy between full Geant4 simulations and
light yield parameterizations for hadronic cascades. This only works when
UseGeant4 is set to true. It works in conjunction with CrossoverEnergyEM.
If one of both is set to a positiv value greater 0 (GeV), the hybrid simulation
is used.
If CrossoverEnergyHadron is set to None while CrossoverEnergyEM is set so
hybrid mode is working, GEANT4 is used for hadronic cascades.
If CrossoverEnergyHadron is set to 0 (GeV) while CrossoverEnergyHadron is
set so hybrid mode is working, hadronic cascades will use parameterizations
for the whole energy range.
:param UseCascadeExtension:
If True, simulate the longitudinal development of cascades. Otherwise,
simulate cascades as pointlike objects.
:param DoNotParallelize:
Try only using a single work item in parallel when running the
OpenCL simulation. This might be useful if you want to run jobs
in parallel on a batch system. This will only affect CPUs and
will be a no-op for GPUs.
:param OverrideApproximateNumberOfWorkItems:
Allows to override the auto-detection for the maximum number of parallel work items.
You should only change this if you know what you are doing.
:param If:
Python function to use as conditional execution test for segment modules.

Tabulate the distribution of photoelectron yields on IceCube DOMs from various
light sources. The light profiles of the sources are computed from the same
parameterizations used in PPC, but like in the direct propagation mode can
be computed using GEANT4 instead.
The mode of tabulation is controlled primarily by the **PhotonSource** parameter.
- *'cascade'* will simulate an electromagnetic cascade of **Energy** GeV at
(0, 0, **ZCoordinate**), oriented according to **Zenith** and **Azimuth**.
The default coordinate system is spherical and centered the given vertex,
with 200 quadratically spaced bins in radius, 36 linear bins in azimuthal
angle (only from 0 to 180 degrees by default), 100 linear bins in the
cosine of the polar angle, and 105 quadratic bins in time residual w.r.t
the direct path from (0, 0, **ZCoordinate**).
- *'flasher'* will simulate a 405 nm LED flasher pulse with the given
**FlasherWidth** and **FlasherBrightness** settings. The source position
and coordinate system are the same as for the 'cascade' case.
- *'infinite-muon'* will simulate a "bare" muon of infinite length. The
coordinate system is cylindrical and centered on the axis of the muon.
Since the muon's position is degenerate with time, the usual parallel
distance is replaced by the z coordinate of the closest approach to the
detection position, and the starting positions of the simulated muons are
sampled randomly (**ZCoordinate** is ignored). There are 100 quadratic
bins in perpendicular distance to the source axis, 36 linear bins in
azimuthal angle (0 to :math:`\pi` radians), 100 linear bins in z
coordinate of closest approach, and 105 quadratic bins in time residual
w.r.t. the earliest possible Cherenkov photon.
:param PhotonSource: the type of photon source ('cascade', 'flasher', or 'infinite-muon').
:param Zenith: the orientation of the source
:param ZCoordinate: the depth of the source
:param Energy: the energy of the source (only for cascade tables)
:param FlasherWidth: the width of the flasher pulse (only for flasher tables)

:param NEvents: the number of events to simulate
:param RecordErrors: record the squares of weights as well (useful for error bars)

'photonics_wham/Ice_table.wham.i3coords.cos094.11jul2011.txt' Photonics-style WHAM! table
:param DisableTilt: if true, disable tilt in ice model
:param Filename: the name of the FITS file to write
:param TabulateImpactAngle: if True, tabulate the impact position of the
photon on the DOM instead of weighting by the DOM's angular acceptance
:param Axes: a subclass of :cpp:class:`clsim::tabulator::Axes` that defines the coordinate system.
If None, an appropriate default will be chosen based on **PhotonSource**.
