BLonD pull request (Alex)
- corrected beam generation from Joel
- energy sampling for radial loop
- to be checked by Kostis
Kostis: testing multi-GPU, -CPU simulations on Greek supercomputer
BLonD-common
Renamings of RF objects/parameters
- "_d" more explicit: "_design"
- Already discussed last time
- counter only in tracking objects? -- for now into tracker, later into assembler
- Helga: should be modified by Assembler
- Markus: had a problem with ghost particles, where both trackers modified the same counter
- Add method to retrieve properties at a given moment (time or counter) -- both for Ring and RF
- Simon: singleton object? to make sure only a single object can write into it
- Kostis: singleton maybe not a good idea, in some cases
- soft copies of Ring parameters into RF?
- was used to have shortcut in e.g. tracker and other objects using it
- Helga: make soft copies in the objects where they are needed for calculation?
- Simon: make them a property? would not allow to modify them from another object
- Alex: e.g. charge = Beam.Proton.charge shorthand notation is useful, because it is used in many objects
- length_ratio: for now to Ring, and make it an array; check if any clash
- phi_modulation, phi_noise
- Helga: different objects act on different parts of the phase
- Simon: should it be in BLonD common at all? not a tracking parameter
- f_rf to be added for convenience?
- Helga: was not added to save memory, natural for tracking
- Alex: sometimes needed, make it a property?
- f_rev in Ring as property
Objects
- RFStation OK
- RFSystem: Single, Full, how to combine?
- For vector sum calculation, want to keep different inputs
- Want to map real hardware
- Have only one RFStation object, that can serve as RF harmonic, or single cavity-amplifier-feedback system -> add classmethods for vector sum etc.
Next meeting in 1 months: RFSystem pseudocode and go through remaining parameters
Markus: still working on synch rad, presentation will come
Panagiotis: had problem with runtime compilation in supercomputer; now also compilation before running
There are minutes attached to this event.
Show them.
