Abstract: Techniques are provided to allow more sophisticated operations to be performed remotely by machines that are not fully functional. Operations that can be performed reliably by a machine that has experienced a hardware and/or software error are referred to herein as Remote Direct Memory Operations or “RDMOs”. Unlike RDMAs, which typically involve trivially simple operations such as the retrieval of a single value from the memory of a remote machine, RDMOs may be arbitrarily complex. The techniques described herein can help applications run without interruption when there are software faults or glitches on a remote system with which they interact.

Abstract: An object of the present disclosure is to provide a provider network device, a network system, and a program that shorten a communication disconnection time during redundancy switching in a Single-Active redundant configuration. The provider network device according to the present disclosure notifies a CE that a VLAN, which has been communicating with traffic, is disabled due to setting of a block point or that new traffic communication is enabled due to releasing of the block point. This allows the CE to quickly delete a previously used transfer database and build up a new transfer database, and thus it is possible to shorten a communication disconnection time during redundancy switching.

Abstract: An object is to provide a network device and the like that enable a first network that determines a traffic communication route using the Ethernet ring protocol and a second network that determines a traffic communication route by transmitting/receiving a control frame related to the traffic communication route within the network to be connected in a redundant configuration. When the network device according to the present invention has transitioned to a state in which there is no interface that can communicate with the first network and there is an interface that can communicate with the second network, it transitions to a standby state and further transmits information indicating that communication is impossible to the second network, and when there is an interface that can communicate with the first network and there is no interface that can communicate with the second network, it transitions to the standby state and further transmits communication route change information to the first network.

Abstract: An object is to provide a communication device, a communication method, and a program that make it possible to suppress an increase in the communication band due to communication via a GWR when Dual Connectivity is implemented, without making an additional setting on base stations. A communication device according to the present invention enables a communication packet to be transferred through a path that is shorter than conventional paths, and can therefore suppress an increase in the communication band. Also, this short cut of the communication path need only be set on the communication device, and need not be additionally set on the base stations.

Abstract: A shared-nothing database system is provided in which parallelism and workload balancing are increased by assigning the rows of each table to “slices”, and storing multiple copies (“duplicas”) of each slice across the persistent storage of multiple nodes of the shared-nothing database system. When the data for a table is distributed among the nodes of a shared-nothing system in this manner, requests to read data from a particular row of the table may be handled by any node that stores a duplica of the slice to which the row is assigned. For each slice, a single duplica of the slice is designated as the “primary duplica”. All DML operations (e.g. inserts, deletes, updates, etc.) that target a particular row of the table are performed by the node that has the primary duplica of the slice to which the particular row is assigned. The changes made by the DML operations are then propagated from the primary duplica to the other duplicas (“secondary duplicas”) of the same slice.

Abstract: Example implementations disclosed herein can be used to build, maintain, and access databases built database in multi-core computing systems with large VRAM and huge NVRAM. The database with optimistic concurrency control can be built on a transactional key-value data store that includes logically equivalent data pages stored in both VRAM and VRAM. Data records in volatile data pages in the VRAM represent the most recent version of the data. Data records in the NVRAM immutable and are organized in a stratified composite snapshot. A distributed log gleaner process is used to process log entries corresponding to transactions on the volatile data pages and construct the snapshot. The log gleaner sorts the log entries by epoch, key range, and most recent use to partition the snapshot across multiple nodes.

Abstract: Systems and methods for reducing latency of probing operations of remotely located linear hash tables are described herein. In an embodiment, a system receives a request to perform a probing operation on a remotely located linear hash table based on a key value. Prior to performing the probing operation, the system dynamically predicts a number of slots for a single read of the linear hash table to minimize total cost for an average probing operation. The system determines a hash value based on the key value and determines a slot of the linear hash table to which the hash value corresponds. After predicting the number of slots, the system issues an RDMA request to perform a read of the predicted number of slots from the linear hash table starting at the slot to which the hash value corresponds.

Abstract: An object is to provide a means for causing wirings and device setting configurations to conform between communication devices and then establishing communication by generating a device setting configuration in accordance with wirings between the communication devices and reflecting the device setting configuration in interfaces of the communication devices. A device setting configuration for establishing communication between communication devices is generated based on information regarding an adjacent device acquired from each communication device, using a network setting information database configured to hold, in an associated manner, information regarding the communication device, information regarding the adjacent device connected directly to the communication device via a communication cable, and information regarding a device setting configuration to be set for an interface of the communication device used to connect to the adjacent device.

Abstract: Provided is a diagnostic device for a coil including a voltage application unit applying an impulse voltage to the coil; a response voltage detection unit detecting a response voltage from the coil with respect to the impulse voltage; an index calculation unit calculating a determination index indicating an electrical feature of the coil based on the response voltage; and a determination unit determining whether there is an abnormality in a target coil to be diagnosed by comparing the determination index of a reference coil that is the coil that is normal and the determination index of the target coil. At least one of a zero cross point at which the response voltage intersects with a reference voltage and a peak voltage on a positive side and a negative side of the response voltage is used as the determination index, in addition to a circuit constant of the coil.

Abstract: Example implementations disclosed herein include techniques for a ready only bufferpool for use in local nodes of a multi-node computing system. Read only transactions executed by a processor can reference a ready only bufferpool resident in a VRAM on the same node. If the desired data page is in the bufferpool the transaction can immediately read data records from the cached data pages. If the desired data page is not in the bufferpool, then the transaction can cause a copy of a corresponding data page in a secondary memory to be installed in the bufferpool. The bufferpool can include more than one copy of a data page simultaneously to handle and prevent cache line misses. Data page are dropped from the bufferpool based on an incrementing per data page counter.

Abstract: Hybrid concurrency control in a database transaction is disclosed. A contention value associated with a database object is read. The contention value is dynamically updated based on access patterns of the database object. If the contention value indicates the database object is under high contention, a pessimistic concurrency control mechanism is applied to the database object. An optimistic concurrency control mechanism is applied to the database object if the contention value does not indicate the database object is under high contention.

Abstract: Techniques are described for offloading remote direct memory operations (RDMOs) to “execution candidates”. The execution candidates may be any hardware capable of performing the offloaded operation. Thus, the execution candidates may be network interface controllers, specialized co-processors, FPGAs, etc. The execution candidates may be on a machine that is remote from the processor that is offloading the operation, or may be on the same machine as the processor that is offloading the operation. Details for certain specific RDMOs, which are particularly useful in online transaction processing (OLTP) and hybrid transactional/analytical (HTAP) workloads, are provided.
