The present disclosure includes apparatuses and methods for in data path compute operations. An example apparatus includes an array of memory cells. Sensing circuitry is selectably coupled to the array. A plurality of shared input/output (I/O) lines provides a data path. The plurality of shared I/O lines selectably couples a first subrow of a row of the array via the sensing circuitry to a first compute component in the data path to move a first data value from the first subrow to the first compute component and a second subrow of the respective row via the sensing circuitry to a second compute component to move a second data value from the second subrow to the second compute component. An operation is performed on the first data value from the first subrow using the first compute component substantially simultaneously with movement of the second data value from the second subrow to the second compute component.

A method and apparatus of a device that determines a cause and effect of congestion in this device is described. In an exemplary embodiment, the device measures a queue group occupancy of a queue group for a port in the device, where the queue group stores a plurality of packets to be communicated through that port. In addition, the device determines if the measurement indicates a potential congestion of the queue group, where the congestion prevents a packet from being communicated within a time period. If potential congestion exists on that queue group, the device further gathers information regarding packets to be transmitted through that port. For example, the device can gather statistics packets that are stored in the queue group and/or new enqueue packets.
