  • Patent number: 10908961
    Abstract: In an embodiment, a method is provided. In an embodiment, the method includes implementing a virtual remote direct memory access (RDMA) component in a virtualization layer on the computer system, the virtual RDMA component having an interface implementing RDMA semantics. An RDMA send request from a send queue associated with a first application running on the first VM is read using the virtual RDMA component, the RDMA send request referencing a send buffer in an application memory space for the first application. The virtual RDMA component then copies or transfers a message in the send buffer to a receive buffer in the second VM. A host computing system configured to implement the method and instructions configured to be executed on a host computing system is also provided.

  • Patent number: 10248182
    Abstract: Methods for performing power management of InfiniBand (IB) switches and apparatus and software configured to implement the methods. Power management datagrams (MADs) are used to inform IB switches that host servers connected to the IB switch's ports are to transition to a reduced-power or offline state or have returned to a normal operating state. A subnet management agent (SMA) on the IB switch receives the power MADs from the host servers and tracks each server's operating state. In response to power down MADs, the SMA coordinates power reduction of the switch's ports and other switch circuitry. For switches with multi-port IB interfaces, a multi-port interface is caused to enter a reduced-power state when all of its ports are connected to host servers that are idle or offline. Additionally, when all of a switch's ports are connected to idle or offline servers the SMA may put the switch's core switch logic into a reduced-power state.

  • Patent number: 10089197
    Abstract: Methods, apparatus, and systems for leveraging an offload programming model for local checkpoints. Compute entities in a computing environment are implemented as one or more sources and a larger number of sinks. A job dispatcher dispatches jobs comprising executable code to the source(s), and the execution of the job code is managed by the source(s). Code sections in the job code designated for offload are offloaded to the sinks by creating offload context information. In conjunction with each offload, an offload object is generated and written to storage. The offloaded code sections are executed by the sinks, which return result data to the source, e.g., via a direct write to a memory buffer specified in the offload context information.

  • Patent number: 10055371
    Abstract: Embodiments of apparatuses and methods for remote direct memory access (RDMA) with commit acknowledgements (ACKs) are described. In embodiments, a device may include a process queue to store a remote direct memory access (RDMA) request from an initiator to update a target memory. The device may further include a control module, coupled to the process queue, to issue a commit operation to the target memory based on the RDMA request and generate an acknowledgement, ACK, to be sent to the initiator on completion of the commit operation. Other embodiments may be described and/or claimed.

  • Patent number: 9749413
    Abstract: Methods and apparatus to provide peer-to-peer interrupt signaling between devices coupled via one or more interconnects are described. In one embodiment, a NIC (Network Interface Card such as a Remote Direct Memory Access (RDMA) capable NIC) transfers data directly into or out of the memory of a peer device that is coupled to the NIC via one or more interconnects, bypassing a host computing/processing unit and/or main system memory. Other embodiments are also disclosed.

  • Patent number: 9632973
    Abstract: Methods, apparatus, and software for implementing RMA application programming interfaces (APIs) over Active Message (AM). AM write and AM read requests are sent from a local node to a remote node to write data to or read data from memory on the remote node using Remote Memory Access (RMA) techniques. The AM requests are handled by corresponding AM handlers, which automatically perform operations associated with the requests. For example, for AM write requests an AM write request handler may write data contained in an AM write request to a remote address space in memory on the remote node, or generate a corresponding RMA write request that is enqueued into an RMA queue used in accordance with a tagged message scheme. Similar operations are performed by AM read requests handlers. RMA reads and writes using AM are further facilitated through use of associated read, write, and RMA progress modules.

  • Patent number: 9582463
    Abstract: Methods and apparatus to provide heterogeneous I/O (Input/Output) using RDMA (Remote Direct Memory Access) and/or Active Message are described. In an embodiment, information is exchanged between an embedded system and a storage device via a source device. The embedded system and the storage device exchange information over a first link and a second link instead of a third link in response to a transfer rate of the first link (coupled between the embedded system and the source device) being faster than a transfer rate of the second link (coupled between the source device and the storage device). The third link is capable to directly couple the embedded system and the storage device. Other embodiments are also disclosed and claimed.

  • Patent number: 9558148
    Abstract: Methods, apparatus, and software for optimizing network data flows within constrained systems. The methods enable data to be transferred between PCIe cards in multi-socket server platforms, each platform including a local socket having an InfiniBand (IB) HCA and a remote socket. Data to be transmitted outbound from a platform is transferred from a PCIe card to the platform's IB HCA via a proxied datapath. Data received at a platform may employ a direct PCIe peer-to-peer (P2P) transfer if the destined PCIe card is installed in the local socket or via a proxied datapath if the destined PCIe card is installed in a remote socket. Outbound transfers from a PCIe card in a local socket to the platform's IB HCA may selectively be transferred using an either a proxied data path for larger data transfers or a direct P2P datapath for smaller data transfers.
