Farewell, CDFGrid

This shows the jobs that have run on CDFGrid over the past 24 months. As many as 5,000 jobs could run at the same time. The level sustained over the last 12 months is anticipated to continue on FermiGrid. Image courtesy of Costas Vellidis, PPD

For more than a decade, CDFGrid was a cornerstone of the Tevatron physics program, serving as the main computing resource for the CDF experiment. Recently the CDF data preservation team, in collaboration with Scientific Computing Division personnel, migrated their analysis efforts to Fermilab's general-purpose grid cluster, GPGrid, taking over the tasks of the experiment-specific CDFGrid. Thus on March 1, CDFGrid was retired after a long, noteworthy run.

CDFGrid was the main computing facility for all of the major results of CDF in the last 10 years and had huge impacts in the field of particle physics. These include the measurements of the W boson mass and the top quark mass with the highest precision in the world; the first observation of single-top quark production, in collaboration with the concurrent DZero experiment; the first evidence for the Higgs boson in a decay channel involving fermions, also in collaboration with DZero; and the first observation of matter-antimatter oscillations in heavy quark flavor.

All these achievements required intensive processing of an enormous amount of experimental and simulated data that would never have been possible without CDFGrid. It supported the production of more than 400 peer-reviewed publications and more than 300 Ph.D. theses by CDF. With its excellent operation by the Fermilab Scientific Computing Division, CDFGrid contributed to a major part of the Tevatron physics legacy.

As many as 5,000 jobs could run in parallel on CDFGrid. The level sustained over the last 12 months is anticipated to continue on FermiGrid through 2015, evidence of the continued interest in this unusual and important data set.

CDFGrid was also a valued resource in the Open Science Grid, a global community of scientists, researchers and experts in high-throughput computing. CDFGrid provided 44 million CPU-hours to other experiments and collaborations over the last three years. The number of computers on the farm has varied over time, peaking at 6,500. The 3,700 computers that remained when this facility was turned off will be migrated to the general-purpose farm, further extending their availability to the science program of the lab.

CDF analysis will continue to thrive; its code base has been modernized to operate on the current general-purpose farm. The 10 petabytes of data can continue to be mined for further scientific results over the next decade or more.

Prepare to be blown away by this picture of comet Lovejoy

From Los Angeles Times, Feb. 27, 2015

What happens when you take a camera that was designed to see things as far as 8 billion light-years away and point it at an object that's a mere 51 million miles away? You get this amazing picture of comet Lovejoy.

The stunning image below is a composite of 62 pictures taken with the Dark Energy Camera, known to its astronomer friends as DECam. The 570-megapixel camera sits nearly 1.5 miles up in the Andes Mountains, at Cerro Tololo Inter-American Observatory. From its lofty perch, it is scanning the night skies to help solve one of the biggest mysteries in science: As the universe expands, why is it speeding up instead of being slowed down by gravity?

To answer that question, DECam is surveying as much of the universe's 14-billion-year history as it possibly can. Seeing further into the past means seeing across mind-boggling distances. This camera, built at the Fermi National Accelerator Laboratory in Batavia, Ill., was specially designed for the task.

Risky business: project risk management

Marc Kaducak

Marc Kaducak, head of the Office of Project Support Services, wrote this column.

Life is full of little gambles known as risks, and so are projects. We can allow risks to paralyze us with fear, or we can objectively assess them and carry on making progress. Project teams perform this assessment by implementing a risk management plan.

Lucas Taylor of U.S. CMS is currently developing a standard project risk management plan with input from the Fermilab project management community. This plan describes how to identify, assess and report risks. Most project teams are already managing risks in a similar manner, and hopefully a standard plan will allow for even more quality, consistency and efficiency.

In general risks are ranked along two axes: 1) the probability of their occurrence and 2) the severity of their impact. Often these things are difficult to quantify precisely, but the act of identifying and roughly ranking risks helps to guide a project's plan. Risks with high ratings along both axes require special attention. Sometimes a risk can be avoided altogether by choosing a different approach such as using a more conservative technology. Certain risks can be transferred to a nonproject entity such as a vendor with insurance or guarantees. Sometimes the most sensible treatment is none at all, also known as accepting the risk. Probably the most common treatment is to actively reduce the probability, impact, or both through additional testing, pursuing two options in parallel, including extra margin or headroom, or any number of other approaches.

Human factors can have significant influence on risk assessments. Our individual perspectives can be limiting, so there is value in seeking input from a diverse group. There is a tendency to overstate risks that are more popularized or sensational versus those that are more statistically significant. The classic example is the fear of flying versus driving. We also have our optimism bias, where we assume that we will succeed where others have failed. One way to convert this optimism into reality is to learn from history, which is why an organized list of risks and lessons learned helps to improve our likelihood of success.

Speaking of optimism, things occasionally go better than planned. In risk management these favorable risks are called opportunities, which can also be ranked in order to pursue those with the most potential upside.

If building our complex projects is somewhat of a gamble, a good risk management plan is like using loaded dice. Roll the bones!

Safety Update

ESH&Q weekly report, March 3

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

An employee fell on the sidewalk and dislocated her right shoulder and scraped her right knee.

An employee fell off a ladder and injured his right ankle. This is a pending claim.
