Personal course is offered for individuals. One batch queue is shared by users of Personal course on a best-effort basis, and is controlled by the fair-share scheduling to prevent the exclusive use.
Group course was designed for using in laboratories and collaborative research groups. A UNIX group and a batch job queue are assigned to each group. A certain amount of resources relative to the requested resources (1/1, 1/2, 1/4, or best-effort) are always ensured depending on course type.
