Abstract: The invention is a compression method having characteristics of smooth compression and internal cooling of the gas. Embodiments of the invention employ a cylindrical chamber and an orbiting rotor to create a moving duct or chamber whose walls converge, relative to a static gas packet drawn into the moving duct, at a “pinch point”. Preferably the closing speed of the walls is subsonic and the speed of the pinch point is supersonic. This enables high pressure to co-exist, at the narrowing end of the duct, with low pressure elsewhere in the duct, because of the pressure information barrier produced by the supersonic advance of the pinch point. The invention also discloses means for providing gas inlet and outlet functionality, and means for providing a variable flow compressor.

Abstract: A method, and apparatus are provided for implementing processor bus speculative data completion in a computer system. A memory controller in the computer system sends uncorrected data from a memory to a processor bus. The memory controller also applies the uncorrected data to error correcting code (ECC) checking and correcting circuit. When a single bit error (SBE) is detected, corrected data is sent to the processor bus a predefined number of cycles after the uncorrected data.

Abstract: A method, apparatus, system, and signal-bearing medium that, in an embodiment, select a command to send to memory. In an embodiment, the oldest command in a write queue that does not collide with a conflict queue is sent to memory and added to the conflict queue if some or all of the following are true: all of the commands in the read queue collide with the conflict queue, any read command incoming from the processor does not collide with the write queue, the number of commands in the write queue is greater than a first threshold, and all commands in the conflict queue have been present for less than a second threshold. In an embodiment, a command does not collide with a queue if the command does not access the same cache line in memory as the commands in the queue. In this way, in an embodiment, write commands are sent to the memory at a time that reduces the impact on the performance of read commands.

Abstract: A method and circuit for implementing multiple active paths between source and destination devices in an interconnect system while removing ghost packets, and a design structure on which the subject circuit resides are provided. Each packet includes a generation ID and is assigned an End-to-End (ETE) sequence number in the source interconnect chip that represents the packet position in an ordered packet stream from the source device. The packets are transmitted from a source interconnect chip source to a destination interconnect chip on the multiple active paths. The generation ID of a received packet is compared with a current generation ID at a destination interconnect chip to validate packet acceptance. The destination interconnect chip uses the ETE sequence numbers to reorder the accepted received packets into the correct order before sending the packets to the destination device.

Abstract: A method and circuit for implementing ordered and reliable transfer of packets while spraying packets over multiple links, and a design structure on which the subject circuit resides are provided. Each source interconnect chip maintains a spray mask including multiple available links for each destination chip for spraying packets across multiple links of a local rack interconnect system. Each packet is assigned an End-to-End (ETE) sequence number in the source interconnect chip that represents the packet position in an ordered packet stream from the source device. The destination interconnect chip uses the ETE sequence numbers to reorder the received sprayed packets into the correct order before sending the packets to the destination device.

Abstract: A computer system includes at least one processor, multiple memory modules embodying a main memory, a communications medium for communicating data between the at least one processor and main memory, and memory access control logic which controls the routing of data and access to memory. The communications medium and memory access control logic are designed to accommodate a heterogenous collection of main memory configurations, in which at least one physical parameter is variable for different configurations. The bits of the memory address are mapped to actual memory locations by assigning fixed bit positions to the most critical physical parameters across multiple different module types, and assigning remaining non-contiguous bit positions to less critical physical parameters. In the preferred embodiment, the computer system employs a distributed memory architecture.

Abstract: A memory controller performs a mirror copy function in a way that allows processor accesses to memory to continue during the mirror copy operations that make up the mirror copy function. Data integrity of mirror copy operations is assured by protocols set up in the memory controller. The result is a memory controller that performs a mirror copy function in a way that allows normal processor accesses to memory to be interleaved with mirror copy operations, thereby minimizing the impact on system performance of executing the mirror copy function.

Abstract: A memory controller optimizes execution of a read/modify/write command by breaking the RMW command into separate and unique read and write commands that do not need to be executed together, but just need to be executed in the proper sequence. The most preferred embodiments use a separate RMW queue in the controller in conjunction with the read queue and write queue. In other embodiments, the controller places the read and write portions of the RMW into the read and write queue, but where the write queue has a dependency indicator associated with the RMW write command in the write queue to insure the controller maintains the proper execution sequence. The embodiments allow the memory controller to translate RMW commands into read and write commands with the proper sequence of execution to preserve data coherency.
