Message definition (META-Farm)
The runtime you choose should be significantly larger than the average runtime of an individual case, ideally by a factor of 100 or more. 
It must definitely be larger than the longest runtime you expect for an individual case. 
On the other hand it should not be too large; say, no more than 3 days. 
The longer a job's runtime is, the longer it will usually wait to be scheduled. 
On Alliance general-purpose clusters, a good choice would be 12h or 24h due to [[Job_scheduling_policies#Time_limits|scheduling policies]]. 
Once you have settled on a runtime, divide the total number of CPU-hours by the runtime you have chosen (in hours) to get the required number of metajobs. 
Round up this number to the next integer.
