The invention relates to a method for clarification of raw green liquor in a sedimentation tank. According to the invention is a part of dregs separated in the sedimentation tank recirculated back into the inflow of raw green liquor, and preferably after passing the dregs through at least one turbulence generator () that could break up larger dregs particles into smaller dregs particles, and thus create larger total surface on the dregs particles, improving sedimentation rate in the sedimentation tank. In a preferred embodiment is the recirculated dregs added into the flow of raw green liquor before a flocculant is added into the flow of raw green liquor and mixed recirculated dregs.

An apparatus and method for controlling a device with shared hardware resources to provide separate execution environments for control and data functions are disclosed. A processor may be configured to generate a first request to access control functions of the device in response to execution of a first thread, and generate a second request to access data functions of the device in response to execution of a second thread. A communication unit may send first indicative of the first request and second data indicative of the second request to the device via first and second ports, respectively.

An apparatus and method for resetting a virtualized device are disclosed. The virtualized device may be coupled to a first port on a communication unit via a first link. The first port may send one or more instructions to the virtualized device via the first link using a first communication protocol. A processor may be configured to detect a reset condition for the virtualized device. In response to the detection of the reset condition for the virtualized device, the first port may disregard one or more transaction requests made by the virtualized device. The first port may further send an error message to the processor in response to receiving a Programmed Input/Output (PIO) request from the processor after the detection of the reset condition.

Implementation of reset functions in an SoC virtualized device

A method and apparatus are disclosed for enabling nodes in a distributed system to share one or more memory portions. A home node makes a portion of its main memory available for sharing, and one or more sharer nodes mirrors that shared portion of the home node's main memory in its own main memory. To maintain memory coherency, a memory coherence protocol is implemented. Under this protocol, load and store instructions that target the mirrored memory portion of a sharer node are trapped, and store instructions that target the shared memory portion of a home node are trapped. With this protocol, valid data is obtained from the home node and updates are propagated to the home node. Thus, no 'dirty' data is transferred between sharer nodes. As a result, the failure of one node will not cause the failure of another node or the failure of the entire system.

Memory sharing across distributed nodes

Providing a property replacement loan offer to a customer that has lost property in a total loss event where the offer is provided automatically in response to an indication of the total loss event. The invention includes computer-based processes that collect customer-specific data for the customer whose property is involved in the total loss event and using this data to prequalify the customer for the property replacement loan. The processing includes accessing a credit bureau to receive data related to the customer's credit.

Providing loan services in the event of a total loss claim

Nodes in a distributed node system are configured to support memory corruption detection when memory is shared between the nodes. Nodes in the distributed node system share data in units of memory referred to herein as 'shared cache lines.' A node associates a version value with data in a shared cache line. The version value and data may be stored in a shared cache line in the node's main memory. When the node performs a memory operation, it can use the version value to determine whether memory corruption has occurred. For example, a pointer may be associated with a version value. When the pointer is used to access memory, the version value of the pointer may indicate the expected version value at the memory location. If the version values do not match, then memory corruption has occurred.

Memory corruption detection support for distributed shared memory applications

A system and method implementing revocable secure remote keys is disclosed. A plurality of indexed base secrets is stored in a register of a coprocessor of a local node coupled with a local memory. When it is determined that a selected base secret expired, the base secret stored in the register based on the base secret index is changed, thereby invalidating remote keys generated based on the expired base secret. A remote key with validation data and a base secret index is received from a node requesting access to the local memory. A validation base secret is obtained from the register based on the base secret index. The coprocessor performs hardware validation on the validation data based on the validation base secret. Hardware validation fails if the base secret associated with the base secret index has been changed in the register of the selected coprocessor.

Remote-key based memory buffer access control mechanism

A method and apparatus for sending and receiving messages between nodes on a compute cluster is provided. Communication between nodes on a compute cluster, which do not share physical memory, is performed by passing messages over an I/O subsystem. Typically, each node includes a synchronization mechanism, a thread ready to receive connections, and other threads to process and reassemble messages. Frequently, a separate queue is maintained in memory for each node on the I/O subsystem sending messages to the receiving node. Such overhead increases latency and limits message throughput. Due to a specialized coprocessor running on each node, messages on an I/O subsystem are sent, received, authenticated, synchronized, and reassembled at a faster rate and with lower latency. Additionally, the memory structure used may reduce memory consumption by storing messages from multiple sources in the same memory structure, eliminating the need for per-source queues.

Hardware message queues for intra-cluster communication

A computer-based method for automatically providing a loan offer to a customer may include: receiving an indication of a total loss event for the customer's property, collecting prequalification data for the customer from a data source comprising customer-specific data, collecting credit data associated with the customer's credit, determining whether to prequalify the customer for a property replacement loan based at least on (a) the collected prequalification data for the customer and (b) the collected credit data associated with the customer's credit, and in response to a determination to prequalify the customer for a property replacement loan, communicating to the customer an offer for the property replacement loan.

The disclosed embodiments provide a system that uses unused bits in a memory pointer. During operation, the system determines a set of address bits in a address space that will not be needed for addressing purposes during program operation. Subsequently, the system stores data associated with the memory pointer in this set of address bits. The system masks this set of address bits when using the memory pointer to access the memory address associated with the memory pointer. Storing additional data in unused pointer bits can reduce the number of memory accesses for a program and improve program performance and/or reliability.

Method and apparatus for using unused bits in a memory pointer

The disclosed embodiments provide a system that validates message-signaled interrupts. During operation, the system receives a message-signaled interrupt from a requesting device. This message-signaled interrupt includes an interrupt vector that identifies an interrupt, and is accompanied by an identification tag that identifies the source of the interrupt. The system uses the interrupt vector to access a stored tag from a tracking mechanism that associates source devices with their assigned interrupt vector(s). The system then compares the identification tag and the stored tag to validate the message-signaled interrupt.
