*At Florida International U., a 'Bootstrap' Approach to Research*

[image: Research by the Bootstraps at Florida International U. 1]

Alex Quesada for The Chronicle

Among the research upgrades under way at Florida International U. is its
"Wall of Wind" hurricane simulator—a subject of considerable interest in
South Florida—with 12 electric fans.

By Jeffrey Brainard

Miami

Like the rest of South Florida, Florida International University has grown
fast. First came the students, many of them children of Cuban immigrants.
And now, perhaps surprisingly for a little-known institution that serves
mostly commuters, the university is pushing to become a major player in
scientific research.

Opened less than 40 years ago, Florida International is Miami's first and
only four-year, public institution. It rose on the grounds of a defunct
airport, inland from the glitz and breezes of Miami Beach.

Since then its rapid growth has made it the country's 20th-largest public
university, with an enrollment of about 44,000. And although South Florida's
historically high population growth has slowed, enrollment is projected to
surge 50 percent by 2020. The university, where Spanish can be heard across
the campus, has become the nation's largest source of bachelor's degrees for
Hispanic students.

Perhaps less well known is the steady expansion of Florida International's
research enterprise. Its federally financed spending on scientific and
engineering research—a key marker of the volume and competitiveness of its
scholarship—was $53.6-million in 2009, placing it 140th among reporting
institutions, up from 161st in 1999. That gain in rank was one of the
largest among research universities during the decade. It put Florida
International ahead of several older research institutions, like Auburn
University and Rensselaer Polytechnic Institute.

Florida International's research budget appears poised to climb still
further. In 2006, its state governing board authorized it to start a medical
school, one of only three non-osteopathic ones created nationally in the
previous 20 years. That will help the university vie for biomedical-research
funds from the National Institutes of Health, by far the largest source of
research funds.

Further expanding its research poses challenges for a university that is
simultaneously trying to keep a lid on its student-faculty ratio, one of the
highest among the nation's research institutions, while coping with deep
cutbacks in state appropriations.

But the story of Florida International's growth to date offers a case study
of what other midsized public research universities, and their legislative
patrons, aspire to do: expand scientific research and educate a lot more
students despite tight finances.

"This was Bootstrap U.," says Thomas A. Breslin, president of the Faculty
Senate and a former vice president for research who oversaw much of the
research growth. "We hired really ambitious and dedicated faculty who were
willing to come to a place where there wasn't much infrastructure."

*Using Its Money to Grow*

One explanation for the growth in federal research money is that Florida
International has primed the pump by spending more of its own internal funds
on its research. That spending, $26.5-million in 2009, more than doubled
during the previous decade. It allowed the university to provide start-up
money for young faculty members.

Florida International succeeded at assembling this pot of internal research
money thanks largely to a feature of the state's financing for higher
education. The Legislature annually doles out money for constructing campus
buildings from its Public Education Capital Outlays fund, financed by a
utility tax. With that support, the university has expanded its research
facilities by about one-third in recent years with space within three new
buildings for the health sciences on its main campus and one for marine
biology on its Biscayne Bay campus.

The pastel-colored buildings are part of a spurt of construction during the
past decade that brought a new museum, architecture school, football
stadium, and parking garages to the main campus.

The buildings themselves have helped Florida International lift its
research, because it collects overhead, or "indirect" cost reimbursements,
from federal grants to help cover the costs of constructing those and
previous campus laboratories. The university has been free to plow that
money back into its own research in subsequent years. It did not issue bonds
to construct the facilities, as other public institutions have done, and so
did not have to use the reimbursements to service debt, notes the provost,
Douglas Wartzok,

It also helped that Florida International's immediate past president,
Modesto A. (Mitch) Maidique, an engineer, steadily advocated for expanded
research during his 23-year tenure, which ended in 2009. Mr. Maidique's big
personality and self-assurance were on display when, in 2008, *The Miami
Herald* noted that he had asked visitors to name the only other college
president, besides himself, who had established schools of architecture,
law, and medicine. The answer, he said: Thomas Jefferson.

*Competing Priorities*

A steep drop in state revenues is hampering all of Florida's public
universities. Florida International's share of base appropriations fell from
$225-million in 2005 to $170-million in 2010.

Another challenge for the university is to maintain its research growth
while also finding funds to hold steady its student-faculty ratio, as both
enrollment and the number of professors continue to grow. In 2009 this ratio
stood at 27:1, the third-highest among all public research universities,
U.S. Education Department data show.

Despite agreeing to finance the medical school, the Legislature has been
cool to financing an expansion of research generally at Florida
International when the state already has two top-tier research institutions,
the University of Florida and Florida State University. In response,
officials here have emphasized how far away they are from those campuses, in
Gainesville and Tallahassee, respectively.

"The urbans"—Florida International and the University of Central Florida,
another fast-growing research institution, in Orlando—"have managed to get
the Legislature increasingly comfortable that we don't intend to be as
comprehensive as Florida and Florida State," says Mark B. Rosenberg, Florida
International's president. "I don't think the allocation of resources from
the Legislature will change appreciably. We'd like to have more support for
our enrollment, but we're not standing around waiting for the Legislature to
fix the challenges that we have."

Florida International has worked to add financing and hire faculty members
in niche areas of science that are a good fit with its strengths and its
region's needs.

That effort has included environmental and marine research to protect the
Everglades and coastal waters; engineering research to prepare for
hurricanes; and public-health research to deal with AIDS and other
conditions that afflict the area's black and Hispanic populations at
disproportionately high rates. In 2008 the university cut 200 jobs and 23
academic programs as part of efforts to better focus its resources on those
and other specified areas.

The university is also expanding its recruiting of accomplished professors.
It increased its faculty of about 900 full-time members by an additional 64
positions during the past year and plans to add 80 next year.

One recent hire was Ranu Jung, a specialist in research on prosthetic limbs
who became chair of biomedical engineering. She was attracted, in part,
because Hispanics are underrepresented in science and engineering. She wants
to encourage more Hispanic students to pursue degrees and careers in
science.

Eventually, Florida International's biomedical-engineering department will
be located adjacent to its new medical school to encourage interdisciplinary
collaborations.

"There was excitement here," she said, "that we were going to build those
bridges."

            <description><![CDATA[1. Finished the parsing function of the proxy.
   The proxy can now parse every kind of iSCSI PDUs from the TCP segments for several client connections.
 
  It can also tell the type of each PDU by looking into the header. For read/write request PDU, SCSI response PDU and SCSI DATA-IN PDU, the proxy needs extra processing to do the scheduling; and other kind of PDUs can just pass by without processing.

   SCSI DATA-IN PDU with the FLAG 0x81 is the response PDU for read request; SCSI response PDU is the response PDU for write request. With this we can know when a request is finished.

   The parsing version prints out each iSCSI PDU(opcode and 48 bytes header) received by the target; for r/w request, it also gets the request size and task tag for the purpose of scheduling; for the r/w response PDUs, it checks task tags to match the requests.

   I tested it with two clients connecting to the same targets, issuing r/w requests,it is working as expected.

2. Integrate the SFQ scheduling with the new parsing proxy. When I tested it, the proxy stuck after issuing iozone write test: the the issuing queue is full of r/w requests waiting for response PDUs. 

   It may because the queue length 4 is too short for large write requests that take a while to finish( get the response PDU). I am still debugging it.]]></description>
