Description
We use ipp for distributed processing of large topographic data sets. Therefore, we typically split the data set into spatial tiles. Each tile is then distributed as separate task through ipp. To give the user detailed feedback on ipp cluster and the processing status, we are planning to create a kind of dashboard application which graphically shows tiles that have been (successfully or not successfully) processed, tiles that are currently computed and tiles that are waiting in the queue.
So we need some sort of mapping between task message id (msg_id) and our tile identifier. Of course it would be possible to store this mapping outside the ipp task database, but it would be a hassle to keep everything aligned/in sync. Things would be much easier, if the task database/interface would allow storing a custom data field (e.g. a comment string or something similar) which could store our tile id. This way no external mapping is needed.
