    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.

    CPC classification number: G06F12/08

    Abstract: Systems and method for memory representation and tracking are disclosed. A storage system may identify a request to allocate memory in a first storage medium. In response to the request, the storage system may represent the memory via at least a first node of a first data structure. The first node may store first information for a first portion of the memory and a second portion of the memory. A criterion may be monitored for at least one of the first portion or the second portion. An order of the first node in the first data structure may be updated based on detecting the criterion.

    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.

    Abstract: A method includes receiving, at a hardware circuit of a device, a target value corresponding to a target data. The method further includes outputting, from the hardware circuit, a first indicator that source data corresponds to the target value. The method further includes, based on the first indicator, outputting, from software executing at the device, a result indicator that the source data corresponds to the target data.

    Abstract: A multi-port memory device in communication with a controller includes a memory array for storing data provided by the controller, a first port coupled to the controller via a first controller channel, a second port coupled to the controller via a second controller channel, a processor, and a processor memory local to the processor, wherein the processor memory has stored thereon instructions that, when executed by the processor, cause the processor to: enable data transfer through the first port and/or the second port in response to a first control signal received from the first controller channel and/or a second control signal received from second controller channel, decode at least one of the received first and second control signals to identify a data operation to perform, the identified data operation including a read or write operation from or to the memory array, and execute the identified data operation.
