Database connection pooling
no vote
Application background The connection pool is a technique for creating and managing a connected buffer pool that is ready to be used by any thread that needs them.This technique is based on the fact that the connection is "pooled": for most applications, when they are processing transactions that typically require a few milliseconds, only 1 threads of access to the JDBC connection are required. When the transaction is not handled, the connection is idle. In contrast, the connection pool allows idle connections to be used by other threads. Key Technology In fact, when a thread needs to operate with a JDBC on a GBase or other database, it requests a connection from the pool. When this thread uses the connection, it will be returned to the connection pool so that it can be used by other threads.

Cloudsim Simulator
4.0
Cloudsim Simulator Australia grids lab, University of Melbourne and the Gridbus project announced the launch of cloud computing called CloudSim simulation software. CloudSim is in SimJava, discrete-event simulation package developed by libraries because SimJava has some limitations, such as: creating a scalable simulation environment will impose the following restrictions: (1) it is not allowed at run time to reset analog programming. (2) it at runtime does not support the creation of new modeling entity (once the simulation has been initialized). (3) as the system scale increases, SimJava characteristics of multi-threading increases performance overhead, excessive context switching between threads lead to performance degradat
