Hi List, I want to share memory between several instances of PD running on separate reserved cores. I've tried the share-mem lib, but it has a very high overhead. Since I am writing custom externals for the puredata patches, I have started to include writing the data to be shared into files on a ramdisk. It does work quite nicely, but I am wondering whether some more elegant solution could be done using the Memory-Mapped Files, or are there any other simple and fast solutions around? Has anyone on this list experience with this? I don't actually need to share large data sets, mostly it's just bytes that indicate the state of the patch. Network based solutions have proven to be too slow. These patches will run on raspberry pi. Thanks!
