Sometimes I can not select a depth 3 or 4 orghammogram for a musician. Why is that?
Producing orghammograms is quite compute intensive, this is specially true for depth 3 and 4 orghammograms. Also, as we add information about recordings to the Hammond Jazz Invenory database the orghammograms of musicians participating on the new recordings have to be recomputed. This is why we have choosen only to offer depth 1 and 2 orghammograms on demand. If a current depth 1 or 2 orghammogram is not available on the server, it will be computed the first time a visitor requests it. This first time requester will have to wait a little for the orghammogram construction to finish. The next visitor will have it delivered almost instantly because after the first requester it will be available on the server. Depth 3 and 4 orghammograms are computed by a process running in the background, independent from visitors requests. If you would like us to provide a currently unavailable depth 3 or 4 orghammogram for a specific musician please leave a message here.
