Abstract: A method includes receiving, at a controller of a computational storage (CS) device, a request to allocate computational storage to an application of a host device. The request includes a resource set ID associated with the application. The method further includes identifying a memory range within a memory region of the CS device. The method further includes storing, in a data structure associated with the resource set ID, an association between a memory range identifier (ID) of the memory range, the memory region, and an offset within the memory region. The method further includes sending the memory range ID to the host device.

Abstract: A method may include receiving, at a storage device, a command using a storage protocol, wherein the storage device is configured to execute a user program, and executing, at the storage device, a device program based on the command. The command may be a first command, and the method may further include receiving, at the storage device, using the storage protocol, a second command, and sending, from the storage device, using the storage protocol, information about the device program based on the second command. The method may further include sending, from the storage device, using the storage protocol, a list of device programs supported by the storage device based on the second command. The method may further include providing, by the storage device, output data from the device program. The providing may include sending, from the storage device, using the storage protocol, a log message.

Abstract: A host interface layer in a storage device is described. The host interface layer may include an arbitrator to select a first submission queue (SQ) from a set including at least the first SQ and a second SQ. The first SQ may be associated with a first Quality of Service (QoS) level, and the second SQ may be associated with a second QoS level. A command fetcher may retrieve an input/output (I/O) request from the first SQ. A command parser may place the I/O request in a first command queue from a set including at least the first command queue and a second command queue. The arbitrator may be configured to select the first SQ based at least in part on a first weight associated with the first SQ and a second weight associated with the second SQ. The first weight may be based at least in part on a first total storage capacity of at least one first namespace (NS) associated with the first QoS level, and the second weight may be based at least in part on a second total storage capacity of at least one second NS associated with the second QoS level.

Abstract: A method of partitioning a graph for processing may include sorting two or more vertices of the graph based on incoming edges and outgoing edges, placing a first one of the vertices with fewer incoming edges in a first partition, and placing a second one of the vertices with fewer outgoing edges in a second partition. The first one of the vertices may have a lowest number of incoming edges, and the first one of the vertices may be placed in a first available partition. The second one of the vertices may have a lowest number of outgoing edges, and the second one of the vertices may be placed in a second available partition. A method for updating vertices of a graph may include storing a first update in a first buffer, storing a second update in a second buffer, and transferring the first and second updates to a memory using different threads.
