Abstract
Embodiments herein describe generating packets that combine an atomic operation (e.g., an atomic fetch) with a data operation (e.g., a put). Previous remote atomics first transmit a packet to a remote node that provides a lock for the data. If the lock is granted, the node transmits another packet containing a data operation which can read or write data. However, the embodiments herein can use a relaxed range-based atomics where the packet uses a range to reserve space in a dataset (e.g., a buffer) at the destination node for the data operation.
Claims17
A computing system, comprising:
- one or more processors;
- and
- memory storing an application which, when executed by the one or more processors, performs an operation, the operation comprising:
- generating a relaxed range for a data operation;
- generating a packet that combines an atomic operation with the data operation;
- and
- transmitting the packet on a network,
- wherein the packet contains an extended transport header (ETH) indicating that the packet contains an atomic operation, and wherein the ETH comprises an add data field that indicates a size of the data operation in a payload of the packet.
A method, comprising:
- generating a relaxed range for a data operation;
- generating a packet that combines an atomic operation with the data operation, wherein the packet contains an extended transport header (ETH) indicating that the packet contains an atomic operation, and wherein the ETH comprises an add data field that indicates a size of the data operation in a payload of the packet;
- and
- transmitting the packet on a network.
A non-transitory computer readable storage medium comprising computer readable program code embodied therewith, the computer readable program code executable by one or more computer processors to perform an operation, the operation comprising:
- generating a relaxed range for a data operation;
- generating a packet that combines an atomic operation with the data operation, wherein the packet contains an extended transport header (ETH) indicating that the packet contains an atomic operation, and wherein the ETH comprises an add data field that indicates a size of the data operation in a payload of the packet;
- and
- transmitting the packet on a network.
