This invention generally relates to one or more computer networks having computers like personal computers or network servers with microprocessors linked by broadband transmission means and having hardware, software, firmware, and other means such that at least one parallel processing operation occurs that involve at least two computers in the network. More particularly, this invention relates to one or more large networks composed of smaller networks and large numbers of computers connected, like the Internet, wherein more than one separate parallel processing operation involving more than one different set of computers occurs simultaneously and wherein ongoing processing linkages can be established between virtually any microprocessors of separate computers connected to the network. Still more particularly, this invention relates to business arrangements enabling the shared used of network microprocessors for parallel and other processing, wherein personal computer owners provide microprocessor processing power to a network, preferably for parallel processing, in exchange for network linkage to other personal and other computers supplied by network providers, including linkage to other microprocessors for parallel or other processing; the basis of the exchange between owners and providers being whatever terms to which the parties agree, subject to governing laws, regulations, or rules, including payment from either party to the other based on periodic measurement of net use or provision of processing power.

Global network computers

A method and system for assigning tasks to peer-to-peer computers connected via a wide area network. The system includes a central computer and one or more remote computers. The central computer and the remote computers operate in one of a pluralility of relationships, including a subscriber relationship and a contractor relationship. In the subscriber relationship, the central computer determines whether a remote computer still subscribes to an Internet Service Provider (ISP) and bills the remote computer accordingly. In the contractor relationship, the central computer polls each remote computer to inquire about the available times when the remote computer is idle and the computational capabilities of the remote computer. The central computer then executes an assignment or scheduling program to assign tasks to idle remote computers for processing. After the idle remote computers finish processing the assigned tasks, the central computer credits a payment to the remote computer. In one embodiment, the remote computer disconnects from the network while processing the assigned task and periodically reconnects to transmit status reports to the central computer.

Commercial distributed processing by personal computers over the internet

A system comprising a personal computer configured to operate with another computer connected to a network of computers. The personal computer includes a microchip having a microprocessor with a control unit and at least two processing units, the control unit being configured to allow a user of the personal computer to control the two processing units, and the microchip including a power management component. The personal computer includes an internal firewall configured to allow and/or deny access to portions of the microchip both to the user of the personal computer and to a user of the microchip from the network of computers during a shared use of the microchip; and the internal firewall is configured to deny access to portions of the microchip from the network of computers.

Microchips with inner firewalls, faraday cages, and/or photovoltaic cells

A personal computer, comprising a microchip, the microchip comprising at least four microprocessors, exclusive of any digital signal processors (DSPs); a non-volatile memory component; a power management component; a internal firewall with a hardware component, the internal firewall being configured to allow and/or deny access to portions of the microchip both to a user of the personal computer and to a user of the microchip from a network of computers during a shared use of the microchip, and the internal firewall being configured to deny access to portions of the microchip from the network; and a wireless network connection mechanism configured to connect the personal computer to the network, the network comprising the Internet.

Internal hardware firewalls for microchips

Networks of workstations make cheap and powerful parallel processors and many systems have been demonstrated using Unix workstations. Personal computers, with their cheap, high performance CPUs, can also be used in a similar way. However, if we are to exploit the multitudes of PCs that sit on desks idle for much of the time, we need robust systems. The uncontrolled environment and physical separation between elements of the parallel system make them prone to a variety of faults that would not normally plague a single processor in a machine room. We describe extensions made to the run-time system for Old MacDonald-a network of PowerPC based Macintoshes-to enable programs written in a functional style using Cilk-a threaded extension of C-to continue in the face of processor and network failures and unpredictable delays likely to be encountered when using widely dispersed machines as components of a parallel system.
