ploughshare is hosted by Hepforge, IPPP Durham


for all your interpolation grid needs

Ploughshare allows users from the HEP community to share fast interpolation grids in a standardised way. PDF fitters and those from the experimental collaborations are be able to upload their validated grids and access the grids of others quickly and with the minimum of fuss. 

What is Ploughshare ?

  1. Quick to use - a web based utility for the automated distribution of fast inperpolation grids for the high energy physcis community.
  2. Secure storage - registered users can upload grid files and corresponding standard format configuration files to describe the grids and physics processes and these are added to a central repository.
  3. Automatic distribution - a standard utility library will be provided to download any required grids automatically in user code.

A utility for the community Ploughshare allows users to share their grids, so it is important that the provenance of the grids is guaranteed. This is achieved by allowing only registered users to upload their validated grids. Subsequently however, anyone is free to download and use the grids as they wish.

Ploughshare is an open source project.

Available grid statistics

Statistics for the submitted grids are collected and reported here

Breakdown by physics process

Statistics on the submitted grids are show here, broken down by number of grids by process, DIS, ep, heavy ion etc.

Eventually, this section may shoe a breakdown of the different grids submited by each of the contributing groups the project.
