HotCRP Conference Management Software

HotCRP is conference management software: it accepts paper submissions and manages the review process. Many conference management packages are available, including EasyChair. HotCRP is especially good at navigating from paper to paper, searching for papers, tagging papers, and managing complex submission and review policies.

HotCRP is open source and requires that you run your own web server. Software requirements: Nginx, PHP version 7.0 or higher, and MySQL version 5 or higher, plus several PHP packages. The README for the latest release has more.

HotCRP was written for the HotNets V workshop in 2006 (based initially on Dirk Grunwald’s CRP), and used thereafter for USENIX 2007, SIGCOMM 2007, SOSP 2007, and SOSP 2009, among many others. It is currently used for all USENIX conferences and many ACM SIGCOMM and SIGPLAN conferences.

If you want a hosted version of HotCRP (so you don’t have to run your own server), try HotCRP.com.

Release News

Upgrading from an old version of HotCRP is easy. If you’re using git, just do git pull. If you originally installed from a tarball, then extract the new tarball over the old one. (Using GNU tar, try “cd HOTCRPDIR; tar --strip=1 -xf /tmp/hotcrp-VERSION.tar.gz”.)

HotCRP Features

Pronunciation note. Greg Minshall pronounces CRP as “crap”, so I suppose you could pronounce HotCRP as “hotcrap”.
