go-trackml

trackml is a Go package to simplify working with the High Energy Physics Tracking Machine Learning challenge.

For more informations about the minute details of what go-trackml tries to do, please have a look at the Python version:

• https://github.com/LAL/trackml-library

trackml is a Go reimplementation of the above Python library.

Installation

$> go get github.com/sbinet/go-trackml

Documentation

Served by GoDoc.

Example

$> go get github.com/sbinet/go-trackml/cmd/trkml-hough

$> trkml-hough -h
trkml-hough uses a Hough transform to make predictions.

Usage:

  $> trkml-hough [OPTIONS] <path-to-dataset> <evtid-prefix> [<path-to-test-dataset]

Examples:

  $> trkml-hough ./example_standard/dataset event000000200
  $> trkml-hough -npcus=+1 ./example_standard/dataset event000000200
  $> trkml-hough -npcus=-1 ./example_standard/dataset event000000200
  $> trkml-hough -npcus=-1 ./train_sample.zip event000001000

Options:

  -ncpus int
    	number of goroutines to use for the prediction (default 1)
  -prof-cpu
    	enable CPU profiling
  -prof-mem
    	enable MEM profiling
  -submit
     	create a submission file

Going parallel

Go has a few built-in facilities to apply concurrent programming. The simple trkml-hough command leverages them:

$> time trkml-hough -ncpus=-1 ./example_standard/dataset event000000200
trkml-hough: loading [event000000200 from ./example_standard/dataset]...
trkml-hough: loading [event000000200 from ./example_standard/dataset]... [done]
trkml-hough: score for event 200: 0.13160123640712013
