Front page changed

August 3rd, 2012 No comments

Some dynamic elements are added to the front page, which now shows a slideshow instead of a random picture. The slideshow controls are also provided (previous, next, and pause/resume). The previous and next buttons are easy to spot, but where is the pause/resume button?

The answer is the page number.

Reducing communication overhead (1) — shared memory approach

May 26th, 2012 No comments

In a computer system employing on-chip accelerator processors such as streaming co-processor or reconfigurable hardware co-processor, it is vital to minimize communication overhead lest the communication overhead cancel out any performance improvement by the co-processor accelerator.

Our first cut approach to this problem, tailored to reconfigurable hardware co-processors that we’ve been working with, is an on-chip shared memory that is little more intelligent than just a scratch-pad memory but less so than a cache. We call it Configurable Range Memory (CRM). Here is an article introducing its basic ideas.

Application-specific hardware and reconfigurable processors can dramatically speed up compute-intensive kernels of  applications, offloading the burden of main processor.  To minimize the communication overhead in such a coprocessor  approach, the two processors can share an on-chip memory, which may be considered by each processor as a scratchpad  memory.  However, this setup poses a significant challenge to the main processor, which now must manage data on the  scratchpad explicitly, often resulting in superfluous data copy.  This paper presents an enhancement to scratchpad,  called Configurable Range Memory (CRM), that can reduce the need for explicit management and thus reduce data  copy and promote data reuse on the shared memory.  Our experimental results using benchmarks from DSP and multimedia  applications demonstrate that our CRM architecture can significantly reduce the communication overhead compared to the  architecture without shared memory, while not requiring explicit data management.

Connect-6 Design Contest

March 7th, 2012 No comments

As part of the 2012 International Conference on Field Programming Technology, there will be a design contest for the best/fastest Connect-6 game designs.

For more details see website: http://www.eecg.toronto.edu/~janders/FPT_2011_competition/ (it is for the previous year, but this year’s rules will be similar)

또 한 가지 중요한 정보는 이 국제 대회를 준비하기 위하여 국내 대회를 개최할 예정입니다. 국내에서 처음으로 개최되는 대회이고 아직 공식 발표된 것이 아니기 때문에 누구든지 지금부터라도 준비하면 괜찮은 결과를 얻을 수 있습니다. 또 처음 개최되는 대회라서 참가자를 유인하기 위하여 많은 상이 마련되어 있는 것으로 알고 있습니다. 관심 있는 학생은 문의바랍니다.

Efficient Writing, Effective Work

January 5th, 2012 No comments

Here are some of Crawford’s tips for maximizing writing work habits:

  • Create a routine
  • Minimize distractions
  • Controlled daydreaming
  • Beware of empty praise or destructive criticism
  • Open your avenues of opportunity

I agree that it’s more of a habit than of one’s ability or anything else.

ACM TACO (HiPEAC 2012) paper accepted!

November 23rd, 2011 No comments

This time, HiPEAC tries a new publication model. Instead of first publishing your paper in a conference, they do a journal review process for all submitted papers, and those accepted papers will have a chance to get presented in a conference, in addition to the journal publication. Our paper on nested loop compilation for reconfigurable architectures, was accepted for this journal issue. Congrats to those involved in this work!

End of Moore’s Law (?)

November 1st, 2011 No comments

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?
