Nathan, > Looks like this is a scif bug. From the documentation:
and from the source code, scif_poll(...) simply calls poll(...) at least in MPSS 2.1 > Since that is not the case I will look through the documentation and see if there is a way other than pthread_cancel. what about : - use a global variable (a boolean called "close_requested") - update the scif thread so it checks close_requested after each scif_poll, and exits if true - when closing btl/scif : * set close_requested to true * scif_connect to myself * close this connection * pthread_join(...) that's a bit heavyweight, but it does the job ( and we keep an infinite timeout for scif_poll() so overhead at runtime is null) i can test this approach from tomorrow if needed Gilles
