摘要： Data is collected by an active node from passive nodes and arranges and stores the collected data on receiving nodes. A source node extracts the data format, and a remote memory blade identification (ID), a remote memory blade address, and ranges of the RMMA space, and composes and sends metadata to the receiving nodes and receiving racks. The RMMA space is unmapped by the source node thereby removing all entries in page tables that map a linear address to a remote RMMA space. The system memory address (SMA) space that is associated with alternative RMMA space is free.

摘要： Various embodiments for performing hardware upgrades in a disaggregated computing environment. A workload is run on a disaggregated computing system while providing a new component to at least one of a plurality of component pools used by the disaggregated computing system. Point-to-point circuit wire level switching is used to switch the disaggregated system from an assigned component residing in a first of the plurality of component pools to the new component residing in a second of the plurality of component pools without interrupting the running workload.

摘要： Embodiments are provided herein for maximizing resource utilization in a disaggregated computing system. A general purpose link is established between a first sub-plurality of computing elements and a second sub-plurality of computing elements. The first sub-plurality belongs to a first plurality of computing components of a first type and the second sub-plurality belongs to a second plurality of computing components of a second type in the disaggregated computing system. A determination is made that the first and second sub-pluralities of computing elements are assigned to a first tenant having first data communications. The general purpose link is secured to the first tenant while allowing second data communications of a second tenant to pass through the general purpose link concurrent with the first data communications of the first tenant.

摘要： An embodiment of the invention includes applying a first partition to a plurality of LPs, wherein a particular LP is assigned to a first set of LPs. A second partition is applied to the LPs, wherein the particular LP is assigned to an LP set different from the first set. For both the first and second partitions, lookahead values and transit times are determined for each of the LPs and related links. For the first partition, a first system progression rate is computed using a specified function with the lookahead values and transit times determined for the first partition. For the second partition, a second system progression rate is computed using the specified function with the lookahead values and transit times determined for the second partition. The first and second system progression rates are compared to determine which is the lowest.

摘要： Photonic circuits are disclosed having an efficient optical power distribution network. Laser chips (InP) having different wavelengths are flip-chip assembled near the center of a silicon photonic chip. Each InP die has multiple optical lanes, but a given die has only one wavelength. Waveguides formed in the photonic chip are optically connected to the lanes, and fan out to form multiple waveguide sets, where each waveguide set has one of the waveguides from each of the different wavelengths, i.e., one waveguide from each InP die. The waveguide network is optimized to minimize the number of crossings that any given waveguide may have, and no waveguide having a particular wavelength crosses another waveguide of the same wavelength. The unique arrangements of light sources and waveguides allows the use of a smaller number of more intense laser sources, particularly in applications such as performance-optimized datacenters where liquid cooling systems may be leveraged.

摘要： Embodiments for optimizing dynamic resource allocations in a disaggregated computing environment. A data heat map associated with a data access pattern of data elements associated with a workload is maintained. The workload is classified into one of a plurality of classes, each class characterized by the data access pattern associated with the workload. The workload is then assigned to a dynamically constructed disaggregated system optimized with resources according to the one of the plurality of classes the workload is classified into to increase efficiency during a performance of the workload.

摘要： Embodiments are provided herein for dynamic memory-based communication in a disaggregated computing system. A pool of similar computing elements is configured as a large address space, the large address space segmented by an identifier. Data travel distances are optimized depending on a historical or expected use of a data object by using a grouping and amortization algorithm to relocate the data object within the pool of similar computing elements at a particular address within the large address space according to the historical or expected use.

摘要： Embodiments for disaster recovery in a disaggregated computing system. A memory is allocated at a secondary, disaster recovery site for data received from a primary site. A degree of resiliency is defined for respective workloads associated with the data at the primary site to specify how critical each respective workload is to execute in case of disaster, and the data is replicated to the allocated memory at the disaster recovery site according to the degree of resiliency.
