 Approved src.alt available as ompl-purdue1-20040324.tar.gz
 Used for 331.art_l base.
 
 For all benchmarks threads were bound to CPUs using the following submit command:
 dplace -x2 -cNTM1,0 $command,
 where NTM1 is the number of threads minus 1.
 This binds threads in order of creation, beginning with the master
 thread on cpu NTM1, the first slave thread on cpu NTM1-1, and so on.
 The -x2 flag instructs dplace to skip placement of the lightweight
 OpenMP monitor thread, which is created prior to the slave threads.
