"Missing" parallel licences

Question

1 answer to this question

  • 0

A user has a parallel FEKO license for 96 processes. The user has 3 jobs running. The 1st job uses 16 processes, the 2nd also 16 processes and the 3rd job uses 32 processes. So there should be 32 processes left for calculation. But SECFEKO only shows 26 to be free. Where are the "missing" 6 licences?

When a parallel job of FEKO is started, then the corresponding number of parallel licences are checked out (e.g. a job using 16 parallel processes will check out 16 parallel processes from the floating licence server). If this FEKO job terminates normally, these 16 parallel processes are then again returned normally.

What might happen, however, is that a FEKO job terminates abnormally (e.g. a network communication failure) and then only some of the 16 processes terminate and return their licence, e.g. 10 are checked back in, but the remaining 6 processes then "hang around" and still use a licence. If these processes are killed the hard way (e.g kill -9 on Linux systems), then they will not return their parallel processes properly as they cannot execute any code if killed the hard way. These parallel instances will be checked-in automatically if for the given parallel licence there is no activity over a certain period (roughly 10 min). These can also be returned when the licence is checked-in manually using SECFEKO_GUI.

However, one must realise that if the same licence is used by multiple parallel jobs, then one cannot check-in the licence, otherwise these other jobs will also terminate then with a licence error.

There is presently no mechanism in the licencing mechanism to only manually return individual parallel instances of a parallel licence while this same parallel licence is still in use by other processes. Only the whole licence as such can be checked-in (or automatially, as soon as any parallel job using the same licence terminates, then after 10 min the licence will be checked in automatically).
