Difference between a positive vs a negative person

November 16th, 2021 Comments off

A quotation from a keynote at “ICT Colloquium 2021” today, “A positive person knows no limit, but a negative person has no result.”  (The two clauses rhyme very well in Korean.)

U-WURF 2013

December 26th, 2013 Comments off

(This was posted using org2blog plugin.)


  • Learn LLVM, the state-of-the-art compiler infrastructure
  • Explore application of compiler techniques to solving interesting problems

LLVM resources


  • creating a module
  • implementing DFG gen (or similar)
  • hacking the front-end

Seminar Topics

  • LLVM (of course!)
  • JIT compilation (?)
  • … any suggestions?

For More Ambitious Students

Study/evaluation of LLVM based JIT translator

  • LLVM-based JIT translator is already designed/implemented
  • The main goal of this activity is to learn the JIT version by running it with benchmarks
  • One possible outcome is to compare its performance with a static version (which is also LLVM-based)
  • If you can improve the performance of the JIT version, it will be fantastic! (probably need an extended period of time…)





There are other interesting projects as well for those who are inclined toward hardware design (such as FPGA) or GPU computing. We will discuss this in the first meeting.

  • other things: SRP trial (paek), VM security thing (youn), GPU profiling (choi)

Graduate students wanted!

November 26th, 2013 Comments off


Image source:

In Embedded Computing Lab, we are currently recruiting motivated graduate students with CS or EE background.

Applications to UNIST for academic year 2014 are still open until at least mid-December.

Senior-level undergraduate students who are interested in the design and optimization of computer architecture/compiler/systems especially for mobile embedded systems are also welcome!

In ICCL lab, we are particularly interested in various (=energy-efficient) ways of implementing computation and programmability.  If you are a good programmer, it will help a lot, but even if you aren’t, you can learn how to program (along with many others) while in the graduate school.  Please contact us if interested.

Our mission as engineers

May 21st, 2013 Comments off

“At Bell Labs, the first thing they told us was that we were there to use our brains, not for just for our engineering skills,” said Chen. “Now that’s what I tell my students.”


Nowadays, I find EETimes articles are much more interesting than those of CACM. The above quote is something that reminds me of our mission as researchers in academia.

End of Moore’s Law (?)

November 1st, 2011 Comments off

I have been thinking of the implications of the possible “End of Moore’s Law”. Read a related article, Is Moore’s Party Over?, in Comm of ACM.

Whether the end of Moore’s law is near is a topic of active debate, so I don’t want to delve into that. But most people will agree that things are slowing down when it comes to computing.

If Moore’s law is over, will even the number of cores be flattened? What would that mean to computer scientists, engineers, programmers, students, and teachers? Where will big innovations be made if it’s not in exponential performance growth?

Month of the Most Deadlines

September 8th, 2011 Comments off

Which month has the greatest number of deadlines for paper submission to conferences in our field? Well, you need to check all the conference deadlines, which is by no means an easy task, but these days it seems that September is definitely in the top class. In comparison, October/November seems to have far less. So what’s in September? DATE, CGO, IPDPS (October 1, so practically September), and I just received C4P for PECCS. Lesson? Summer is perhaps the best season to concentrate on conference papers…

Specialties of US states

July 25th, 2011 Comments off

According to US Bureau of Labor Statistics, the New York state has the highest concentration of fashion designers, and in California you have the highest chance of coming across parking enforcement workers. Understandably, game dealers can be most commonly found in Nevada, but it is a little known fact that telemarketers are most concentrated in Utah. Pennsylvania has the highest concentration of mental health counselors, in Floria you are most likely to meet pest control workers!

* Data from US Bureau of Labor Statistics, of May 2009.

Which Major Will Pay You the Best?

July 18th, 2011 Comments off

For many students in Electrical and Computer Engineering major,there seems to be some sort of envy toward some other thingslike physics and material, at least here in UNIST. Here it is, you who major in ECE, the actual datathat “shows” that the future is brighter for us!


The graph above compares the wage distributions among different occupations (data from the US Bureau of Labor Statistics, see below). The wages shown in the legend (on the right) are on an hourly basis. So the red segments represent the highest level of wage in this chart whereas light green represent the lowest level of wage. As can be seen, in the case of managers (e.g., CEO) and lawyers, more than 30% of them are very well paid. On the other hand, Food Preparation and Serving Related occupation (e.g., waiters and waitresses) has the large portion of the lowest paying jobs.

Then how is the prospect for our ECE (Electrical and Computer Engineering) graduates? As you can see, from the chart above, Computer Scientists/Engineers and Engineers in general belong to the top paying occupations. More than 10% of the CS graduates enjoy the highest level of wages, which is on the same level as Healthcare Practitioners and Technical (e.g., medical doctors and paramedics).  Moreover, in those three Engineering/Science related occupations (the three occupations in red boxes in the chart) low paying jobs are much rarer than in other occupations. So the average income of those in the three Engineering/Science occupations will substantially higher than others.

Lastly, I would like to emphasize that those majoring in CSE have a much better outlook even compared to those majoring in general engineering or some life/physical/social sciences. In fact, Computer and Information System Scientists/Engineers are frequently cited as the highest paying positions across all occupations. Now you have good reasons to take pride in your choice if you have chosen CSE. 🙂

The original data and more detailed statistics can be found in here: (of May 2010), and
