lume-impact-live-demo

Demonstration of LUME-Impact running a live model fetching data from the LCLS EPICS network

Setup

Make the lume-live-dev environment: conda env create --file environment-dev.yml

Convert notebooks to .py files:

./build.bash

EPICS:

ssh -fN -L 24666:lcls-prod01.slac.stanford.edu:5068 centos7.slac.stanford.edu
export EPICS_CA_NAME_SERVERS=localhost:24666

Test with: caget KLYS:LI22:11:KPHR

Run

For example, LCLS on SDF:

python lume-impact-live-demo.py

TOML properties file

Running the simulation requires definition of the following variables within a toml file:

Variable	Description
host	Host of Impact sim
config_file	Impact configuration file
distgen_input_file	Input to distgen generation
workdir	Working directory of simulation run
summary_output_dir	Output directory for summary files
plot_output_dir	Output directory of plot files
archive_dir	Output directory for archive files
shapshot_dir	Output directory for snapshot files
distgen_laser_file	File for generating distgen input
num_procs	Number of processes to use
mpi_run	command for running mpi

Running on SDF additionally requires:

Variable	Description
impact_command	Command for Impact execution
impact_command_mpi	Command for running MPI

Default configurations are given in the example environment files packaged with this repository.
