Abstract: Example implementations relate to scheduling of jobs for a plurality of graphics processing units (GPUs) providing concurrent processing by a plurality of virtual GPUs. According to an example, a computing system including one or more GPUs receives a request to schedule a new job to be executed by the computing system. The new job is allocated to one or more vGPUs. Allocations of existing jobs are updated to one or more vGPUs. Operational cost of operating the one or more GPUs and migration cost of allocating the new job are minimized and allocations of the existing jobs on the one or more vGPUs is updated. The new job and the existing jobs are processed by the one or more GPUs in the computing system.

Abstract: Example implementations relate to consensus protocols in a stretched network. According to an example, a distributed system includes continuously monitoring network performance and/or network latency among a cluster of a plurality of nodes in a distributed computer system. Leadership priority for each node is set based at least in part on the monitored network performance or network latency. Each node has a vote weight based at least in part on the leadership priority of the node. Each node's vote is biased by the node's vote weight. The node having a number of biased votes higher than a maximum possible number of votes biased by respective vote weights received by any other node in the cluster is selected as a leader node.

Abstract: Example implementations relate to edge acceleration by offloading network dependent applications to a hardware accelerator. According to one embodiment, queries are received at a cluster of a container orchestration platform. The cluster includes a host system and a hardware accelerator, each serving as individual worker machines of the cluster. The cluster further includes multiple worker nodes and a master node executing on the host system or the hardware accelerator. A first worker node executes on the hardware accelerator and runs a first instance of an application. A distribution of the queries is determined among the worker machines based on a queuing model that takes into consideration the respective compute capacities of the worker machines. Responsive to receipt of the queries by the host system or the hardware accelerator, the queries are directed to the master node or one of the worker nodes in accordance with the distribution.

Abstract: Systems and methods are provided for performing burst packet preloading for Available Bandwidth (ABW) estimation, that may include: preparing a chirp train to be used for ABW estimation, the chirp train comprising a quantity of original probe packets; determining a quantity of additional probe packets that will transition the network path from a short-term mode into a long-term mode; inserting the determined quantity of additional probe packets at the beginning of the chirp train; and transmitting the chirp train, including the determined quantity of additional probe packets on the network path, to a receiver that can perform ABW estimation of the network path.

Abstract: Example implementations relate to a proactive auto-scaling approach. According to an example, a target performance metric for an application running in a serverless framework of a private cloud is received. A machine-learning prediction model is trained to forecast future serverless workloads during a window of time for the application based on historical serverless workload information. The serverless framework is monitored to obtain serverless workload observations for the application. A future serverless workload for the application at a future time is predicted by the trained machine learning prediction model based on workload observations. A feedback control system is then used to output a new number of replicas based on a current value of the performance metric, the target performance metric and the predicted future serverless workload. Finally, the serverless framework is caused to scale and pre-warm a number of replicas supporting the application to the new number.

Abstract: Systems and methods are provided for available network bandwidth estimation using a one-way-delay noise filter with bump detection. The method includes receiving one-way delay measurements for each probe packet in a probe train sent over the telecommunications path; grouping the probe packets into a plurality of pairs based on the one-way delay measurements; for each pair, computing a respective noise threshold based on the one-way delay measurements of all the probe packets transmitted after a later-transmitted probe packet of the pair; selecting one of the pairs according to the noise thresholds and the one-way delay measurements for the probe packets of the pairs; and estimating the available bandwidth on the telecommunications path based on transmission times of the probe packets in the selected pair.

Abstract: Techniques and architectures for measuring available bandwidth. A train of probe packets is received from a remote electronic device. A network transmission delay for at least two packets from the train of probe packets is measured. Network congestion is estimated utilizing the at least two packets from the train of probe packets. An estimated available bandwidth is computed based on the network transmission and estimated network congestion. One or more network transmission characteristics are modified based on the estimated available bandwidth.
