    Abstract: In some examples, a processor receives a first request to allocate a memory region for a collective operation by process entities in a plurality of computer nodes. In response to the first request, the processor creates a virtual address for the memory region and allocates the memory region in a network-attached memory coupled to the plurality of computer nodes over a network. The processor correlates the virtual address to an address of the memory region in mapping information. The processor identifies the memory region in the network-attached memory by obtaining the address of the memory region from the mapping information using the virtual address in a second request. In response to the second request, the processor performs the collective operation.

    Abstract: Systems and methods are provided for sparse matrix vector multiplication with a matrix vector multiplication unit. The method includes partitioning a sparse matrix of entries into a plurality of sub-matrices; mapping each of the sub-matrices to one of a plurality of respective matrix vector multiplication engines; partitioning an input vector into a plurality of sub-vectors; computing, via each matrix vector multiplication engine, a plurality of intermediate result vectors each resulting from a multiplication of one of the sub-matrices and one of the sub-vectors; for each set of rows of the sparse matrix, adding elementwise the intermediate result vectors to produce a plurality of result sub-vectors; and concatenating the result sub-vectors to form a result vector.

    Abstract: Some examples relate to providing a fabric-attached memory (FAM) for applications using message passing procedure. In an example, a remotely accessible memory creation function of a message passing procedure is modified to include a reference to a region of memory in a FAM. A remotely accessible memory data structure representing a remotely accessible memory is created through the remotely accessible memory creation function. When an application calls a message passing function of the message passing procedure, a determination is made whether the remotely accessible memory data structure in the message passing function includes a reference to the region of memory in the FAM. In response to a determination that the remotely accessible memory data structure includes a reference to the region of memory in the FAM, the message passing function call is routed to a FAM message passing function corresponding to the message passing function.

    Abstract: In accordance with example implementations, a process includes receiving, by a connector that is associated with a compute node and is associated with a fabric-attached memory (FAM), an application programming interface (API) called to perform an operation that is associated with a hierarchical data format (HDF) object of an HDF file. The API call includes a HDF object identifier, which corresponds to the HDF object. The process includes, responsive to the request, based on the HDF object identifier, accessing, by the connector, mapping information that is stored in the FAM; and using, by the connector, the mapping information to identify a FAM descriptor corresponding to a first data item that is stored in the FAM and corresponds to the HDF object. The process includes, responsive to the request, serving, by the connector, the API call responsive to the identification of the FAM descriptor.
