The HEPiX forum brings together worldwide Information Technology staff, including system administrators, system engineers, and managers from the High Energy Physics and Nuclear Physics laboratories and institutes, to foster a learning and sharing experience between sites facing scientific computing and data challenges. Participating sites include BNL, CERN, DESY, FNAL, IHEP, IN2P3, INFN, JLAB, NIKHEF, RAL, SLAC, TRIUMF and many others. The HEPiX organization was formed in 1991, and its semi-annual meetings are an excellent source of information and sharing for IT experts in scientific computing.

Pre-History

First, throughout the 80s, there was HEPVM, a very successful collaboration of the major HEP labs which concentrated on the IBM VM operating system then in common use. In 1988, in a meeting at NIKHEF, there was a first attempt by several European labs to create something similar for UNIX. At CHEP in Oxford later that year, Willem van Leeuwen (NIKHEF) tried to get some user support for the idea. Unfortunately, these were without apparent success.

A History of HEPiX

HEPiX really started at CHEP’91 in Tsukuba, Japan. Representatives from SLAC (Les Cottrell), FNAL (Judy Nicholls) and CERN (Alan Silverman) recognised the possibilities and advantages of learning and mastering the brave new world of UNIX in partnership with other institutes. With HEPVM as a model, they proposed to set up a series of regular meetings with invitation to all HEP labs to discuss issues of mutual concern.
They started with 2 Chapters, one in North America, one European, plus a common meeting associated with CHEP conferences. At CHEP Annecy, we decided there was more strength in one world-wide organisation with joint meetings: Meetings to be every 6 months, on opposite sides of the Atlantic plus a meeting associated with CHEP conferences.
The very first meetings were actually scheduled alongside those of HEPVM, for example one in NIKHEF in 1993 was called HEPmix.

HEPiX Working Groups

HEPiX forms specific groups from time to time to target specific areas. Some working groups may be long-lived, others may exist to perform a given task and then disband. In general the groups will report their activities either through conference proceedings, by issuing news, by publishing documents or by some combination of these. We will maintain mailing lists of people working in such groups as long as the working groups are active.

HEPNT Created

Meanwhile, in 1997, the HTASC sub-committee of HEP-CCC created HEPNT, chaired by Dave Kelsey of RAL to look into the use of Windows in HEP sites. Initially, HEPNT was a closed group by invitation only although they held their first open meeting in CERN in December 1998. Since October 1999, their meetings have been associated with, subsequently merged with, those of HEPiX.

Participants

The group is intended for High Energy Physics institutes and academic establishments concerned with High Energy Physics. But its activities are not closed and anyone is welcome to participate in its meetings, its maillists, and so on. However, the activities of the group should remain focused on HEP since there are many other forum where general UNIX/Windows topics are covered. Currently, there are over 180 names on the mailing list.

The participants work at the IT departments of the following research institutes:

Working Groups

In general the groups will report their activities either through conference proceedings or by issuing news or by publishing documents or by some combination of these. We will maintain mailing lists of people working in such groups as long as the working groups are active. To add your name to a list, see the descriptions of the groups below and contact the convener of the one(s) which interest you. (But remember that most groups will make their results public at the appropriate time so joining an interested party list is not necessary just to get access to the results of the work of any group.)

 

Active Working groups

Batch Monitoring
The objective of this newly-formed working group is to provide guidance on a community-driven effort to employ and support a common set of batch monitoring solutions. Current activities include investigating HTCondor monitoring tools presently deployed, documenting features of existing solutions and making recommendations on best practices.
CPU Benchmarking
The working group investigating Benchmarks. The current task is twofold; firstly to find a replacement for HEPSPEC06 and secondly to suggest a fast benchmark that can be run at the beginning of a job.
BIT Preservation
The working group forming to respond to a request by the DPHEP collaboration for advice on technical matters of bit preservation.
Configuration Management
The working group was created to share information, experiences and where possible code, amongst sites using various config management solutions. Currently in 'Observer Mode'
IPv6
The working group was created in April 2011 with the following aims: first, consider whether and how IPv6 should be deployed in HEP (especially for WLCG), then propose a timetable and consider the implementation plan (e.g. advice on end system and firewall configuration) during transition period.

 

Past Working groups

Virtualization
At the Fall 2009 Berkeley meeting, a Virtualization Working Group was set up chaired by Tony Cass (CERN). The group completed its mandate, gave a final report at the Beijing meeting (Fall 2012), and wound down.
Storage
This site is meant to reflect some of HEPiX activities in the field of storage technology. Apart from a collection of past presentations, one may consult here the pages of the HEPiX/IHEPCCC Storage Working Group. The Group was aiming to provide information and practical advice on storage solutions for participating institutions and beyond; the group was closed down quite some years ago.

Co-Chairs

Helge Meinhard of CERN was appointed European Co-Chair at our Spring 2012 Prague meeting, replacing Michel Jouvin of LAL IN2P3.

Tony Wong of Brookhaven National Laboratory was appointed North-American Co-Chair at the Fall 2014 meeting in Lincoln (Nebraska), replacing Sandy Philpott of Jefferson Lab.

The principal role of co-chair is to coordinate the preparation of their respective North American and European HEPiX meetings, helping the local organizers to establish the agenda, the choice of convenors and make sure that the working groups will present their reports during the meeting. They are also working together on all common HEPiX subjects. Co-Chair appointments are for the period of 3 years, and renewable for one additional appointment.
