Distributed processing of shared content

A computer memory holding instructions executable by a processor of a specified client device to distribute content data from a broadcast-source device to a plurality of networked client devices in a social media network environment, the instructions comprising:

• instructions to compute a threshold number of recipients for recursive parallel distribution, wherein the threshold number is based on a number of online users of the social media network environment;
• instructions to, in response to a distribution request by a broadcast user wherein a requested number of recipients is above the threshold number, receive the content data from a first ring of client devices at the specified client device, the specified client device being one of a second ring of client devices, each client device of the second ring having a unidirectional pointer to another of the second ring of client devices and having one or more second-ring computer-memory containers;
• instructions to distribute the content data to one of the second-ring computer-memory containers upon determining that the one of the second-ring computer-memory containers is a destination container corresponding to one or more users following the broadcast user in the social media network environment,
• instructions to forward the content data from the specified client device to exactly one client device of the second ring based on the unidirectional pointer, and to store the content data at the one or more second-ring computer-memory containers identified as a destination container, wherein the content data is forwarded unidirectionally and recursively to each of the client devices of the second ring via the sub-node pointers of the client devices of the second ring;
• instructions to, responsive to identification of a bidirectional connection pointer to exactly one associated client device of a third ring of client devices, distribute the content data to the exactly one associated client device, each of the third ring of client devices being arranged outside of the second ring of client devices, having a unidirectional pointer to another of the third ring of client devices, and having one or more third-ring computer-memory containers, wherein each client device of the second ring of client devices is connectable to a client device of another ring of client devices via a bidirectional connection pointer;
• and
• instructions to compare a number of connections of the broadcast user to the threshold number, and, when the number of connections is below the threshold number, to provide a distribution list including one or more destination containers and receive distribution of the content data from the broadcast-source device directly to the one or more destination containers.
