team discovers star

Fermilab scientists Douglas Tucker of SCD and William Wester of PPD,
visiting Professor J Allyn Smith from Austin Peay State University, and
interns Samuel Wyatt and Mees Fix identified a cataclysmic variable
star while looking for white dwarf stars as part of the Dark Energy
“They’re not unusual, but they’re really interesting scientifically,”
says Smith. “[This type of star] is the progenitor of a Type I
supernova,” although this particular star won’t explode for millions of
Cataclysmic variable stars are actually a set of two stars, one white
dwarf and one normal. The super-dense dwarf draws matter away from the
companion star, which forms an accretion disk around the star. When
matter falls into the star or when the disk becomes very dense and
heated, it emits radiation.
Fix made the actual discovery, when he noticed these emissions while
analyzing the star’s spectroscopy. He brought the results to the group,
who recognized the emissions pattern as one belonging to a cataclysmic
Although it appeared in sky surveys dating back to the 1950s, no one
had previously identified this object as a cataclysmic variable star.
“It took a young summer student to clean up the spectra that we
recorded to identify it,” said Wester.
While the star can’t be used as a part of the Dark Energy Survey, the
team plans to do further research to discover more about this

Science display at Indian
Prairie Public Library in honor of Adam Lyon's talk
(SCD/Scientific Programs/Intensity Frontier)
spoke last month about the
g minus 2 (gm2) experiment at both the Woodridge Public Library and the
Indian Prairie Public Libary in Darien. Turnout to both presentations
was good, with 40 attendees in Woodridge despite short notice and
corresponding lack of publicity and 75 in Darien. Both library
directors were impressed. The director at Indian Prairie said they do
not often get a turnout that big, and though they have rarely hosted
science-related talks, they will be doing more now.
"I had a lot of fun giving the talks, and the enthusiasm of the
audiences was terrific," says Lyon. "Fermilab received lots of warm and
fuzzy feelings from the public!"

Letter from Rob Roser: Snowmass on
For nine days earlier
this month, nearly 700 physicists from
almost 100 universities and laboratories in the United States, as well
colleagues from around the world, gathered in Minneapolis for the final
of the 2013
Community Summer Study. The last
time the high energy physics community got together to do this exercise
back in 2001. The
physics landscape has
changed dramatically since then.
These nine days were the
culmination of a nearly year-long
process in which the high energy physics community wrestled with
the most compelling physics opportunities over the next decade or so
that we as
a field want to answer.
This process was about
taking stock in what we have learned
and starting the process for charting our future. It took
a broad view of the field – not only were
the three “science frontiers” (energy, intensity and cosmic) discussed
there was also a computing frontier and instrumentation frontier as
well as discussions
on facilities and communications and outreach.
To my mind, this is the
first time in these planning
processes that both computing and instrumentation was given such a high
– recognition from our community of its importance to doing this
science. Our own
Lothar Bauerdick co-chaired the
computing frontier with Steve Gottlieb, a lattice gauge theorist with
University of Indiana. Fifteen
of SCD attended Snowmass, and all played significant roles in both the
computing and/or instrumetation sessions as well as his or her
interest. Ian Fisk
journeyed from CERN
to Minneapolis to deliver an excellent colloquium talk
looking forward in computing.
I would like to thank all
of our SCD members that
participated in the process. I
Snowmass was a great success, and each individual had an impact. It was great to see so
many scientists with
diverse interests and opinions come together to chart the course for
physics. A truly astonishing range of physics topics and technology
capabilities were explored and discussed in detail.
Snowmass is not the end –
but rather the first step in
writing down the field’s priority-based plan. That job will commence in
the coming month
with the re-establishment of
the US Particle Physics Project Prioritization Panel (P-5). The
Snowmass process will
provide the basis
for this plan.
three-year grant for network research
Wenji Wu (left) and Phil
Demar, through a grant from DOE, will work with BNL on improving data
transfer by developing a middleware tool.
Last month, DOE awarded a
three-year grant to a proposal led
by the CCD Network Research group and in collaboration with Brookhaven
Laboratory (BNL) to develop “Multicore-aware Data
(MDTM).” The aim of
the research, according to Principal
Investigator Wenji Wu, is to speed up data transfers by developing a
scheduler to harness multicore technology.”
Data transfer involves
the sending system, the network and the
receiving system. The
overall speed and
efficiency depends upon the performance of each of these components; if
is slower, it constrains the overall performance, reducing, or possibly
negating, advanced capabilities available elsewhere.
“[It’s] like building a high-speed highway
network,” says Wu, “but if your car is not fast, then you cannot go
This is a recognizable
problem for systems facing
ever-increasing demands for data transfer.
While network technology is moving into the
realm of 40 to 100-gigabit
per second transfers and many systems now feature multiple CPUs, we
need to develop
the other elements, like middleware, to match.
This grant will support
Fermilab’s development of a
distributable prototype MDTM tool.
Ultimately, the tool will
provide four major
will provide data transfer-centric
scheduling and resource management capabilities. MDTM
schedules and assigns system resources based on the needs and
requirements of data transfer applications. The characteristics of individual data
transfer process threads will be factored into core scheduling
decisions, a feature that does not exist today.
will introduce topology awareness
into process/thread scheduling as well. Data transfer threads belonging
to the same data transfer will be assigned to the same nodes on
systems. In addition, data transfer threads will be assigned to cores
near the I/O devices they use (I/O device locality).
It will manage
process migration among
cores in a manner that minimizes the host-induced out-of-order packet
issues that arise from unmanaged process migration.
will introduce a capability for
differentiated services and prioritization in process resource
assignment and scheduling.
BNL’s contribution will
be to adapt data transfer
applications for MDTM.
can see the
synergy between Fermilab developing the middleware itself and
[providing] the hooks and necessary modifications to BBCP [a data
tool] to use it,” says the Network Research group leader, Phil Demar.
So, the team is preparing
to soup up the engine and
accelerate up the highway.
