I work in a french firm called Thomson Detexis and we use your Ptolemy software. We would like, in the CGC domain, to use clusters that could integrate BDF scheduler (only in these clusters). The target used is unixMulti_C, shedName is HIER and childType is Makefile_C. Actually, only SDF scheduler is accepted in a cluster (this is the field : loopScheduler, SDFScheduler or Cluster). So when we write the field : BDFScheduler, I call in this case BDF functions rather than SDF functions (this is virtuals functions). But it seems that there is problems with ports index of BDF cluster. So I would like to know : what do you think of the difficulty to develop these kinds of clusters? In what direction can I follow my studies? In advance, thank you.
