Re: Computing in High Energy Physics '91, Tsukuba Japan 11-15 March 1991.
22 May 1991
ABSTRACT.
The international Computing in High Energy Physics meeting, held 11-15
March 1991, in Tsukuba Science City Japan is summarized.
CHEP'91.
High energy physicists are engaged in "big ticket" physics. These are the
people whose experiments require the large accelerators at CERN, Fermi
National Accelerator Lab (FNAL), National Lab for High Energy Physics in
Japan (KEK), the Super Collider at Texas (SSC), etc. The experiments
generate massive amounts of data. Experiments can generate 100
megabytes/second of data, a terabyte a day, and a pentabyte a year.
Acquiring, moving, and storing this data needs high speed, high bandwidth
networks, libraries of tapes and other external storage devices as well
as automated retrieval systems.
Processing the data is required first in real time during the
experiments, and then as post processing afterwards for analysis. For
both of these requirements, the computing needs have always outstripped
the capabilities of whatever was the current fastest supercomputer.
Related theoretical analysis, such as lattice gauge theory, which does
not depend on the experimental data, also requires tremendous computing
resources which will barely be satisfied by teraflop computers. In fact,
special purpose computers are being built specifically for some of these
analyses.
Each year high energy physicists from around the world who are interested
in computing come together for their annual meeting (Computing in High
Energy Physics-CHEP). This year it was held in Tsukuba Science City,
about one hour outside Tokyo, from 11-15 March 1991. This was truly an
international meeting as the participant's list summary below shows.

There were 30 plenary talks and 84 presentations in the parallel and
poster sessions. There was also a small exhibition by vendors. Because
several other meetings were being held during the same week I was only
able to attend the first day and a half of this conference, and I missed
a great many fascinating-sounding papers. The purpose of this summary
is to provide my general impressions of the work as far as I was able to
assess it. Many thanks to Professor Yoshio Oyanagi (University of
Tokyo), and Mr. Sverre Jarp (CERN) who participated in all of CHEP '91,
read this report and made important suggestions. A complete list of the
titles and authors of the papers is attached to the end of this report.

(1) High energy physics computing demands are at least as great as those
in some better known fields, such as fluid dynamics, molecular modeling,
etc.
(2) The scientists working in high energy physics are already using
large, interconnected, state of the art hardware for their experiments.
Thus the use of complicated computer networks and collections of
distributed computers for data processing and analysis does not put them
off. Rather, they have been doing distributed and parallel computing for
years using "farms" of minicomputers, typically Vax's. Vax computers
are so ingrained into the culture that performance is measured in VUPs
(Vax Units of Performance). Postprocessing of data is also done on
whatever is the largest machine available (in Japan these are typically
FACOM or Hitachi mainframes). A good deal of the "tracking" computations
can be vectorized but not much else. However, there is a definite
movement toward RISC workstations and parallel computers. In fact, the
computing environment surrounding some of these experiments may be more
sophisticated (although often homegrown) than in laboratories that are
famous for supercomputing. Also at the software level these labs are
already dealing with some extremely large (often multi-millions of
lines) source programs. Few software tools are being used, and most of
those are either homegrown or vendor supplied utilities. Thomas Nash
(FNAL, nash@fnal.fnal.gov) emphasized the need for research in software
engineering to aid in software management.
(3) The high energy physics community has more or less spurned
mainframes and related centralized services. HEP code has never been
cost-justified on expensive supercomputers or mainframes because the
highly computational programs (1) are often small and (2) rarely
vectorize. Hence the interest for cheaper systems (Unix and RISC) that
offer the promise of the huge computer quantities that the community
needs. At the same time they realize that supercomputer companies can
offer some services that cannot be duplicated elsewhere.
David O. Willims from CERN (davidw@cernvm.cern.ch) discussed
the relationships between mainframes and workstations as seen by his
constituency. With respect to the question "is the role of the mainframe
terminated" he made the following conclusions.
* General purpose mainframes as we know them in HEP are at the start of
their run-down phase. This phase will take about 5 years in HEP and
longer in the general marketplace.
* The services provided by these mainframes are essential and over time
will be provided by more specialized systems.
He urged mainframe builders to realign prices towards the workstation
server market, emphasize integration, push the mainframes I/O advantage
relative to workstations, perform research related to quickly accessing
vast quantities of data on a worldwide basis, and emphasize
dependability, service, ease of use, and other things that will have a
big payoff for scientists. (Robert Grossman from U Illinois,
grossman@uicbert.eecs.uic.edu, echoed a part of this by pointing out that
performance of database systems will have to be dramatically improved.
For example the "distance" between two physical events in a 10^(15) item
DB can be very great. Thus the first query will always be expensive, but
research needs to be done on methods to speed up subsequent queries.)
Williams' advice for workstation builders is to maintain aggressive
pricing, emphasize integration, push I/O capacity, develop good
peripherals and multiprocessors.
I believe that most of the audience agreed with his points.
(4) Specialized computers for simulation, in particular quantum
chronodynamics, have been built, or are under development in US, Japan,
Italy, and perhaps other countries. These QCD machines include one at
Columbia University, Italy's APE, Tsukuba University's QCDPAX, IBM
Yorktown Heights' GF11, and FermiLab's ACP-MAPS. The Japanese QCDPAX
project began in the late 1970's and is now running with 480 nodes and a
peak speed of about 14GFlops (see also my report PAX 12 April 1990),
beginning its fifth generation. The Columbia machine has almost as long a
history and is of similar performance. The following table (from the
paper given by Iwasaki) gives some details of existing parallel computer
projects dedicated to lattice gauge theory.

Several new machines are in the pipeline. A teraflop machine for QCD has
been proposed to the US Department of Energy by a collaboration of
scientists from (mostly) US universities and National Laboratories. New
machines are under development at Fermi Lab, and other places. The
Japanese Ministry of Education, Science, and Culture (MOMBUSHO) has just
approved funding of the next generation PAX (about $10M US from 1992-
1996). All of these are estimating performance in the range of several
hundred gigaflops within the next few years. The network topology of QCD
machines has been getting more sophisticated too, moving from 1D (16
CPU), 2D (16x16), 3D (16x16x8), to 4D (16x16x8x8). There are still plenty
of problems though, as neither the topology nor control structure (SIMD,
MIMD, ?) is really settled. In addition, reliability (MTBF) as well as
pin and cabling issues have to be addressed. Nevertheless at the leading
edge, some of these scientists are already talking about performance
beyond one teraflop.
(5) The community is very international, with visits to each other's
labs and joint projects being very common. For example, Katsuya Amako
(KEK- Japan) pointed out that in each of the Tristan experiments (Venus,
Topaz, Amy) physicists from almost 17 institutes are participating.
Frankly, this is one of the most well mixed international research
communities that I have seen. A glance at the joint authorship of many
papers presented at this symposium testifies to this fact. Consequently
there is a great deal of data sharing and savvy about advanced computing
and networking. There is not much going on within their world that is
not rapidly known by all the active participants. (I urge readers, even
nonspecialists, to scan the attached list of papers in order to get a
sense of how close to the front of the technology wave this community is
riding.) On the other hand there does not seem to be nearly as much
communication between this group and others doing high performance
computing. I see several reasons for this, including an intuitive sense
by the physicists that they have the best expertise needed to treat
their problems (because their computing needs are so special purpose),
and an almost exclusive dependence on VMS software until recently--thus
an isolation from the Unix world. High energy physicists are moving
heavily and rapidly from minicomputers to workstations, and a "wind of
Unix" was definitely blowing through the conference. The growth of Unix
is already bringing people closer together and I am very optimistic that
all parties can learn from each other. In particular, it seems to me
that as computing becomes more distributed, the experiences of the
physics community who have actually been doing this for some time can be
beneficial in more general situations. Similarly, the physicists can
learn from computer scientists and algorithm developers who have broader
views. Incidentally, Japanese contributions in this area are bound to
increase rapidly; when Unix is the accepted standard, then the best
hardware will be easily adopted worldwide.
(5) For the future, the participants see data storage, cpu power, and
software as three crisis issues. Networking between remote scientists and
the experiment, or among scientists, was seen as something that needed to
be beefed up, but not emphasized as at a crisis stage. In Japan, future
high energy physics projects are viewed as large international
collaborations, and there is a strong feeling that a more unified
worldwide HEP computing environment is needed.
(6) Parallel computing is moving more into the mainstream of Japanese
science. Two Japanese parallel computers that I reported on within
the past year (QCDPAX and AP1000) were used to perform real work
presented at this meeting. In addition, some applications of transputers
were also shown. I am predicting that we will see this trend continue as
Japanese-built parallel machines are installed in other "friendly"
outside user installations.
