Until then, I'm very interested in any suggestions for how I can hack it on the app side, but preferably still using libtiff for as much as possible. My read of the libtiff internals is that although I can read or write raw (uncompressed) strips or tiles, the codec implementations are have state and are therefore not reentrant -- I can't call them in parallel on multiple raw strips that I've already read, nor can I call the compressors on multiple data blocks to generate raw strips in parallel.
Yes, but you can do the compression yourself in parallel, then jam the already-compressed strips into libtiff...
