AY 201213: We are moving PDC topics further down into CS1 and CS2, fleshing out PDC coverage in our intermediate objectoriented development course (CS 313), and stepping up evaluation.

[for discussion]

To teach PDC topics effectively, they should not be taught

in isolation. Instead, they should be taught in the context

f relevant software engineering best practices. (Go beyond

functional and performance requirements.)

Mobile applications backed by RESTful cloud services are

rapidly emerging as the mainstream paradigm of computing [Christensen, OOPSLA '09]. PDC curricula should embrace it.

C CS S1 1

Spring 2013: separate section aimed at majors in physics and
ther hard sciences
includes some material on numerical methods at the K and C levels
about 9 class hours were dedicated to sequential and parallel

versions of these algorithms and the possible resulting speedup using data parallelism in C#

example: threads for speeding up trapezoidal rule integration

C CS S2 2

emphasis on PDC topics in CS2 starting in fall 2011
9hour PDC module on task parallelism, speedup, and load

balancing in algorithms involving arbitrary precision arithmetics

presentation at C/A levels in the form of various examples
example: compute Fibonacci numbers based on repeated

squaring of 2by2 matrices of BigIntegers in Java

experiment with the speedup and load balancing btw. tasks

since fall 2011: C#, emphasis on PDC topics
since fall 2012: Java + Android as context for

concurrent/distributed comp. topics (18h C/A)

concurrency and coordination
design forces: safety, liveness, performance
external events and internal timers
background threads
progress reporting and cancelation
offloading computation to cloud

// local task: i is number to check final long half = i / 2; for (long k = 2; k <= half; k += 1) { if (isCancelled() ) break; publishProgress((int) ((k / half) * 100) ) ; if (i % k == 0) return false; } return true;
