Allocate Jobs to Machines Based on Percentages

All taskers in Accelerator offer a consumable resource called PERCENT with total available count equal to 100. By default, jobs use none of this resource. Although the PERCENT resource was originally designed as a way to get exclusive host access for a job, the recommended way to run a job with exclusive access is to specify the CORES/N resource request, where N is the total number of logical cores on that node.
