 Detect CPU bound and I/O bound processes  Increase process priority for CPU bound processes and lower nice value  Lower priority for I/O bound processes and increase nice value  Control operation using a system call  Toggle functionality  Set parameters  Log detection and changes to process priority

 Virtual machine (VM)  2GB RAM  2 2.1GHz cores  Ubuntu  3.8-rc6 Kernel

 Kernel/sched/fair.c  Include/linux/syscalls.h  Arch/x86/syscalls.tbl

 Phoronix  Automated open source testing framework   Chess test suite  Tscp – AI algorithm for the game of chess  Custom AI project test  Classification

 High deviations in collected data both with and without modifications  Caused by virtual environment?  Time skew issue wasted a lot of time  Would have tested/validated modifications more  Would have cleaned up the code a bit more  Would have explored rt, se  Etc.  Slow VM!!!!
