摘要:
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.

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.

摘要:
A biometric authentication system includes an image database and a user database containing user profiles. Each user profile is associated with a selected image in the image database as an image key and with an ocular biometric data record obtained from an eye of the associated user. A user input terminal receives asserted user credentials, an eye scanning module obtains ocular biometric data, and a position detection module detects an eye position or eyelid position. An access control module communicates with the user database for obtaining a user profile associated with the asserted user credentials, communicates with a display device for displaying the image key associated with the obtained user profile, communicates with the position detection module for verifying the biometric authentication system by detecting whether the user is viewing the image key, and communicates with the eye scanning module for obtaining ocular biometric data and authenticating the user.
