Age	Commit message (Collapse)	Author
2011-08-25	add cuda sorting/searching algorithms in src/sorting.h	Anthony LaTorre

2011-08-23	Fix Likelihood to use self.sim instead of the global sim, so now it	Stan Seibert
	imports properly. Also correct a units bug in the default time range for the PDFs. We work in units of seconds, not nanoseconds!
2011-08-22	Oops, uncomment other benchmark tests	Stan Seibert

2011-08-22	Use PDF created on GPU in likelihood calculation. This is 11x faster than ↵	Stan Seibert
	before.
2011-08-22	Benchmark and unit test for PDF creation	Stan Seibert

2011-08-22	Expose interface to PDF creation on the GPU in the Simulation class.	Stan Seibert

2011-08-22	Enable creation of charge and time PDF on GPU	Stan Seibert

2011-08-21	nreps was not actually being used properly by the Simulation class	Stan Seibert

2011-08-21	Add new nreps parameter to Simulation.simulate() to allow the same initial ↵	Stan Seibert
	photon distributions to be propagated multiple times. Default nreps is 1.
2011-08-21	Repeating iterator that returns the item from the parent iterator multiple ↵	Stan Seibert
	times before moving to the next element.
2011-08-20	fix bug in Likelihood class; pdfs for each pmt were the same histogram	Anthony LaTorre

2011-08-20	merge	Anthony LaTorre

2011-08-20	add likelihood class to evaluate likelihoods for detector events.	Anthony LaTorre

2011-08-20	remove old commented code	Anthony LaTorre

2011-08-20	sim.py displays help if run with no arguments	Anthony LaTorre

2011-08-20	Gar! GEANT4 needs the world volume resized to contain our lone box of material.	Stan Seibert

2011-08-20	A failing test demonstrating the faiure of G4ParallelGenerator to produce ↵	Stan Seibert
	photons when the parent particle is at (1,0,0)
2011-08-20	A simple unit test of the constant particle gun	Stan Seibert

2011-08-20	Assign base RNG seed when none is given in G4ParallelGenerator.	Stan Seibert

2011-08-20	Convenience gun generator when all inputs are constant.	Stan Seibert

2011-08-20	Missing import from fileio.root	Stan Seibert

2011-08-19	Do the hash-bang correctly at the top of the benchmark script.	Stan Seibert

2011-08-19	Benchmark photon load times	Stan Seibert

2011-08-19	merge	Anthony LaTorre

2011-08-19	ignore first kernel call in benchmarks	Anthony LaTorre

2011-08-19	Liquid argon properties from MiniCLEAN	Stan Seibert

2011-08-19	Rename test scripts so nose will find them.	Stan Seibert

2011-08-19	merge	Anthony LaTorre

2011-08-19	add benchmarks for ray intersection and photon propagation	Anthony LaTorre

2011-08-18	merge	Stan Seibert

2011-08-18	Actually pass the max_steps variable in sim.propagate_photons to the	Stan Seibert
	GPU class.
2011-08-18	Unit test to verify that photons at normal incidence do not abort.	Stan Seibert

2011-08-18	Replace Rayleigh scattering implementation with that from SNOMAN. The	Stan Seibert
	angular distribution is slightly different, and now fits with the distribution given in the GEANT4 physics reference manual. Unit test is now included to verify the correctness of the scattering.
2011-08-18	Could have run off the end of the array by 1 because the queue counter ↵	Stan Seibert
	points to the next available photon slot.
2011-08-18	Fix bug that caused photons to NAN_ABORT if they hit a triangle	Stan Seibert
	at exactly normal incidence. The plane of incidence was undefined in that case, but should have been the plane normal to polarization vector.
2011-08-18	merge	Anthony LaTorre

2011-08-18	make default camera resolution widescreen. fix checkerboard scene.	Anthony LaTorre

2011-08-17	Start of MiniCLEAN geometry.	Stan Seibert

2011-08-17	add grouper function from the itertools example	Stan Seibert

2011-08-17	event module is no longer part of generator package	Stan Seibert

2011-08-17	Add flag to Simulation() and Geometry.build() to ignore the BVH cache.	Stan Seibert

2011-08-17	Put the temporary ZeroMQ IPC socket file into /tmp directory.	Stan Seibert

2011-08-17	merge	Stan Seibert

2011-08-17	Switch to ZeroMQ for both directions of communication between	Stan Seibert
	the GEANT4 processes. Also handle sending the initial particle vertices from a thread in the main process to avoid possible deadlocking if the vertex queues fill up.
2011-08-17	Switch from multiprocessing.Queue to ZeroMQ push/pull socket for moving ↵	Stan Seibert
	photon information around. Improves LBNE performance from 1.4 to 2 Mphotons/sec.
2011-08-17	move useful bits from view.py into camera.py and get rid of view.py	Anthony LaTorre

2011-08-17	merge	Anthony LaTorre

2011-08-17	import chroma modules from subpackages with import chroma.module_name	Anthony LaTorre

2011-08-16	merge documentation changes	Stan Seibert

2011-08-16	Remove some unused parts of generator/photon.py	Stan Seibert
