If your job does not use the system openmpi, or does not use MPI, then any desired core binding will need to be set up with whatever mechanism the software uses. Otherwise, there will be no core binding. Again, that may not be a major issue. If your job does not work well with HT then run on a number of cores equal to half of the number of slots requested and the OS scheduler will minimize contention.
new SGE utilities
While SoGE is very similar to previous versions of SGE there are some new utilities that people may find of interest. There are manual pages for each of these.
