Keeping cool at Grid Computing Center

Aside from the accelerators, nothing at Fermilab uses as much energy as its three computing centers.

That's why the laboratory's computing staff is constantly searching for ways to increase energy efficiency. The latest of these ideas is, if you'll pardon the expression, a pretty cool one — workers are installing glass doors and plastic panels between server racks at the Grid Computing Center to keep the cold air in and to reduce the energy used to keep the equipment from overheating.

According to GCC Manager Adam Walters, for every megawatt of power the servers use processing data, it takes another half megawatt to keep them cool enough to operate. Step into the Grid Computing Center, and you'll be hit with a wave of sound — hundreds of fans running at once inside hundreds of servers on metal racks.

Those racks are arranged with hot aisles and cold aisles between them. Rather than keep the entire room at a frigid temperature, the cold aisles direct colder air where it's needed most — into the server air inlets — and the hot aisles give the warmth the servers generate somewhere to go. Traditionally, the cold air has been kept in using plastic curtains, but the new sliding doors and top panels will allow less of it to escape, Walters said.

"This should allow us to run fewer fans and run the ones that are on more slowly," Walters said. "That will enable us to use less electricity."

It will also help equalize the temperatures in the cold aisles, which will allow for better control. Additionally, the plastic panels over the top of the aisles will shrink under extreme heat and fall away, clearing the way for the sprinkler systems in the event of a fire.

Walters said this idea has been talked about for roughly five years, and computing staff visited other institutions to see how it has been implemented. The project involves the installation of 16 sets of sliding doors and plastic panels between server racks at a cost of $90,000. The work is under way and should be complete by early November. If it saves a significant amount of money, Walters said, the idea may expand to the Feynman and Lattice computing centers.

This is just the latest in a line of energy-saving practices at Grid Computing Center, practices that have led to the U.S. Environmental Protection Agency awarding its Energy Star status to the center for three years running. Walters said that status means that GCC is in the top 25 percent of data centers in the country when it comes to energy efficiency.

Cutting down on energy consumption is part of the culture at the Grid Computing Center, Walters said, and the staff will continue to seek out new ideas.

"Efficiency is important because we use a lot of energy out here," Walters said. "We're saving the lab money, and that's money that can be used for other mission-critical projects."

Accelerator Update

Accelerator update, Nov. 4

Proton Source
AD personnel worked on a Linac ESS ground fault and fixed an arcing problem in the BRF19 high-voltage junction box.

Main Injector/NuMI
Between Oct. 28 and Nov. 4, the Main Injector provided 122 hours of proton beam to the NuMI target for the production of neutrinos for MINERvA, MINOS and NOvA. The machine delivered an integrated intensity of 5.97 x 1018 protons on target.

AD personnel, with assistance from the alignment group, continued to work on understanding and correcting the Recycler aperture restrictions.

AD personnel worked on extraction and beamline tuning.

Fixed-target area: Test Beam Facility
AD personnel worked on tuning beam for the experiments in the Fermilab Test Beam Facility.

Fixed-target area: SeaQuest
Experts conducted NM1 polarity checks and continued vacuum leak checks in preparation for the startup of the SeaQuest experiment.

New charged charmonium-like states observed at BESIII

From, Nov. 4, 2013

(IHEP, Beijing) Since the discovery of the electrically charged Zc(3900), a possible four-quark object, the Beijing-based BESIII Collaboration has made a rapid string of related discoveries. While quarks have long been known to bind together in groups of twos or threes, these new results seem to be quickly opening the door to a previously elusive type of four-quark matter.

From the Particle Physics Division

Creative thinking during tight budgets

Mike Lindgren

Mike Lindgren, head of the Particle Physics Division, wrote this column.

This week we are in the middle of the annual DOE Science and Technology review. The preparation for this review has given us an opportunity to reflect on important questions about the quality of our science program, how well we are operating the facilities and how well we are serving the needs of our user community.

I don't know anyone who enjoys being reviewed, but preparing for reviews does remind us of how much we accomplish. For instance, as we gathered information from the first months of accelerator operations after the shutdown, we were reminded of the immense effort that had gone into improving our experiments and test beam facilities and that they are going to perform even better than they did before the shutdown.

At the same time, these reviews also remind us that we can do better and that we need to set priorities. When some efforts only provide marginal improvements, we should focus our activities on new things or strengthen efforts that need help to make them world-class. A good example is the new Experiment Operations Center, which will occupy the current One North meeting space in Wilson Hall; construction will begin later this year. Consolidating Intensity Frontier experiment operations into one modern location for experiment and beam monitoring, access control and shifts will serve detector operations well for the next decade and beyond.

I always appreciate when people offer ideas to make things better, whether they are simple efficiency improvements in our daily work or big ideas about revamping our technical facilities by building state-of-the-art, integrated workplaces to better serve science.

My first reaction often is to say that budgets are tight, but then I remind myself that there is no better way to quash initiative than to tell people that. Instead, I challenge my colleagues and myself to figure out how we can accomplish at least some of these good ideas within our existing funding. That is not an easy task, but our lab has a history of being innovative and doing hard things. I believe we can embrace this as a challenge, knowing that if we do a great job, we will be serving the country and community well.

As we prepared for the review, I saw evidence for people who already think that way. We will take those good ideas, ask for more of them, work together to select the best and make them happen safely and efficiently.

Doing that while running experiments and operating this great research complex is not easy, but I think the people in the Particle Physics Division and across the laboratory are quite capable of it.

Fornax galaxy cluster

The Dark Energy Survey has posted this detailed image of the Fornax galaxy cluster. The survey will measure the distributions of galaxies that are far away from Earth and compare them to the patterns of galaxies closer to Earth. Differences in these patterns give indispensable clues about how dark energy has affected spacetime over the last several billions of years. Read more in Dark Energy Detectives.

Safety Update

ESH&Q weekly report, Nov. 5

This week's safety report, compiled by the Fermilab ESH&Q Section, contains two incidents.

An employee was exposed to scintillator oil on her right forearm, after which a red patch appeared on her arm. She received first-aid treatment.

An employee experienced electric shock from cables that were not grounded or connected to a device. He later felt mild pain in his right hand and elbow. He received medical treatment.

Find the full report here.
