BibTeX does not have the right entry for preprints. This is a hack for producing the correct reference:
@booklet{EasyChair:14488,
author = {Cristian Campos and Rafael Asenjo and Javier Hormigo and Angeles Navarro},
title = {Computing DTWs on CPU, GPU and FPGA with SYCL},
howpublished = {EasyChair Preprint 14488},
year = {EasyChair, 2024}}
