A test instrument for MCPL_input_once

Identification

• Site: Tests_MCPL_etc
• Author: Peter Willendrup
• Origin: DTU
• Date: Mar 2024

Description

This is a unit test for the MCPL_input_once component. Since Oct 2026 MCPL_input_once
is an INHERIT of MCPL_input with repeat_count=1 and replicate_across_processes=0 forced:
the file content is shared among MPI processes and every particle is used once.

Examples

(Test cases in bold)

• Test: -n1e3 v_smear=0.1 MCPLFILE=voutput.mcpl.gz Detector: m1_I=2.42284e+11
• Test: -n1e3 v_smear=0.1 MCPLFILE=voutput_legacy Detector: m1_I=2.42284e+11

Input parameters

Parameters in boldface are required; the others are optional.
