According to SGE 5.3 Manual,
Slots – The number of jobs which may be executed concurrently in that queue
I am new to these concepts and want to start by understanding one by one.
For suppose, if RAM is 10G and if there are 10 slots, and hence 1G per slot, then does only jobs less than 1G can be run? And if the job needs only some 0.5G, it will be wasting the remaining 0.5G in that slot right? And if so, what's the use of grid then if there is no optimization of the resources?
And if a job of 2G is shared among multiple slots, is this called a parallel job or normal job?
And is there any difference between queue and slot concept in SGE v5.3 and v6.0 & above?
