摘要： A system and method for provisioning virtual machines in a virtualized environment includes determining a relationship between capacity need and performance for virtual machines (VMs) stored in memory storage media. Aggregate capacity needs for a plurality of VMs consolidated on a same physical server are estimated. VM combinations that yield capacity gains when provisioned jointly are identified such that when peaks and troughs are unaligned in capacity needs for a set of VMs, the set of VMs is provisioned together.

摘要： Affinity-based preferential call technique, in one aspect, may improve performance of distributed applications in a hybrid system having heterogeneous platforms. A segment of code in a program being executed on a processor may be intercepted or trapped in runtime. A platform is selected in the hybrid system for executing said segment of code, the platform determined to run the segment of code with best efficiency among a plurality of platforms in the hybrid system. The segment of code is dynamically executed on the selected platform determined to run the segment of code with best efficiency.

摘要： A clock offset between a client and a server is measured by: (a) the client sending a request to the server; (b) upon receiving the request in step (a), the server optionally sending a server acknowledgement to the client; (c) upon the client receiving the server acknowledgement in step (b) or directly, if no acknowledgement was used, each of the client and the server proceeding to concurrently exchange their respective timestamps with each other a multiplicity (n) of times, thus forming a multiplicity (n) of timestamp exchanges; and (d) determining a plurality of apparent forwards and backwards delays based on the multiplicity (n) of timestamp exchanges. The preferred apparent forwards and backwards delays are then selected based on the minimum values (for each direction) determined in (d) above. The clock offset between client and server is then determined based on the preferred apparent forwards and backwards delays.

摘要： A method, information processing system, and computer program product manage server placement of virtual machines in an operating environment. A mapping of each virtual machine in a plurality of virtual machines to at least one server in a set of servers is determined. The mapping substantially satisfies a set of primary constraints associated with the set of servers. A plurality of virtual machine clusters is created. Each virtual machine cluster includes a set of virtual machines from the plurality of virtual machines. A server placement of one virtual machine in a cluster is interchangeable with a server placement of another virtual machine in the same cluster while satisfying the set of primary constraints. A server placement of the set of virtual machines within each virtual machine on at least one mapped server is generated for each cluster. The server placement substantially satisfies a set of secondary constraints.

摘要： In an exemplary aspect, method, apparatus, and program products are disclosed suitable for clock offset determination. One method includes performing a number of exchanges of at least single bytes with another network node, where values of the single bytes are different for the exchanges. The method also includes capturing and storing timestamps for each of the number of exchanges performed on the network node. A second method includes capturing and saving arrival timestamps for each of a number of timing messages in a set of timing messages received from another network node. This second method also includes sending the timestamps to at least the another node in response to completion of the set of timing messages.
