This is the one that called odp_init_global().

An implementation could also support other than child processes joining an instance, so this definition is too narrow. We'll need to add an ODP instance ID param into local init, but other than that, its implementation specific how ODP threads join an ODP instance (not always parent -> child connection). Also, can the instantiation process exit ODP? On some implementation it could and the instance terminates when the last ODP thread exits it. So in general terms ODP thread in Linux: any pthread or process that is running as part of an ODP instance (have called odp_init_local()). -Petri _______________________________________________ lng-odp mailing list lng-odp@lists.linaro.org https://lists.linaro.org/mailman/listinfo/lng-odp
