Abstract: A parallel processor network comprised of a plurality of nodes, each node including a processor containing a number of I/O ports, and a local memory. A  communication path is established through a node by comparing a target node address in a first address packet with a processor ID of the node. If node address is equal to the target node address a receive channel is allocated to the input port and a route ready command is sent over an output port paired with the input port. If the node address is not equal to the target node address, then a first unallocated output port is selected from a port vector and the address packet is forwarded to a next node over the selected output port.

Abstract: A process for producing potassium sulfate, sodium sulfate, and sodium chloride from potash and a sodium sulfate/water source, wherein potash (12), sodium sulfate (14), slurry (34) from the recovery stage and brine (18) from the gaserite decomposition stage (20) are introduced to a first stage (10), wherein the sodium sulfate and potash dissolve, such that glaserite is precipitated. The slurry is concentrated and delivered (22) to the glaserite decomposition stage (20) along with water (24). Potash is introduced directly (8) and/or via stream (22) by introducing excess potash into stage (10). The potassium sulfate solids are separated, washed and dried to give a potassium sulfate product (27). The mother liquor (18) removed from the reactor is returned to the glaserite production stage (10). The brine (26) produced in the production of glaserite (10) is evaporated in an evaporative crystallizer (28). The removal of water (30) produces a supersaturation of sodium chloride, which precipitates out of solution.
