• Project 3 update

  Soft realtime applications describe their scheduling requirements using the leaky bucket traffic parameters, as shown in the project description. But this class is implemented as a bandwidth preserving server, I encourage you to use weighted fair queuing. For an example see the following paper:

  Pawan Goyal, Xingang Guo, and Harrick M. Vin, A Hierarchical CPU Scheduler for Multimedia Operating Systems, Operating Systems Design and Implementation, Seattle, WA, Oct. 1996.

• Test code for you Project

  I have placed a test application for projects in the cse522 account. I have tested it on the CEC Linux hosts against my wuthread library. You can get it from the following directory:

          /home/cec/class/cse522/src/wuthreads/testapp.c
  

  I have also included a makefile and my wuthread library so you can always compile this test app to verify it still works against my library. Grab the Makefile, testapp.c and Linux/libwth.a and give it a try.
