Methods, apparatuses, and computer program products for load balancing servers are provided. Embodiments include determining, by a balance module, for each server within a rack comprising a plurality of servers, a vertical position of the server relative to the other servers within the rack; selecting from the plurality of servers, by the balance module, based on the determined vertical positions of the servers, a particular server to assign a workload; and assigning, by the balance module, the workload to the selected server.

Methods, apparatuses, and computer program products for synchronously debugging a software program using a plurality of virtual machines are provided. Embodiments include controlling, by a master debugging module operating on a first virtual machine, execution of the software program within the first virtual machine; controlling, by a slave debugging module operating on a second virtual machine, execution of the software program within the second virtual machine including delaying execution of the software program within the second virtual machine relative to the execution of the software program within the first virtual machine; detecting, by the master debugging module, an error in the execution of the software program within the first virtual machine; and in response to the detection of the error, capturing, by a hypervisor, a snapshot of the second virtual machine.

摘要:
A computer program product is provided for managing workload in a computer system. Computer usable program code cause a first compute node to broadcast a workload bid request to a plurality of compute nodes, wherein the workload bid request includes workload parameters. The compute nodes each receive the request from the first compute node, and each compute node uses the workload parameters to calculate a cost of running the workload. One or more individual compute nodes within the plurality of compute nodes send a workload bid to the first compute node, wherein each workload bid includes the cost of running the workload on the individual compute node sending the workload bid. The first compute node receives and uses each workload bid to select a target compute node to run the workload, wherein the target compute node is selected from the individual compute nodes and the first compute node.

A computer-implemented method for workload management in a computer system is provided. According to the method, a first compute node broadcasts a workload bid request to a plurality of compute nodes, wherein the workload bid request includes workload parameters characterizing the workload. The plurality of compute nodes each receive the workload bid request from the first compute node, and each of the plurality of compute nodes uses the workload parameters included in the workload bid request to calculate a cost of running the workload. One or more individual compute nodes within the plurality of compute nodes each send a workload bid to the first compute node, wherein each workload bid includes the cost of running the workload on the individual compute node sending the workload bid. The first compute node receives each workload bid and selects a target compute node to run the workload.

Methods and systems for generating still images and video by capture of images projected by light passing through a display screen are disclosed. According to an aspect, a method includes controlling light emitting components of a display screen to activate in a sequence for displaying a sequence of images. For example, in an organic light emitting diode (OLED) display screen, the method may include controlling a subset of the display screen OLEDs to activate in sequence to display a sequence of images. The displayed sequence of images may appear to a viewer of the display screen to be a still image or a video. The method may control light emitting components different subsets of the LEDs to be activated in the sequence, such that different areas of the display screen display images in each part of the sequence.
