If multiple threads call increment() concurrently, the outcome is unpredictable. The increment operation might not be atomic (meaning it's not guaranteed to be executed as a single, indivisible step). This could lead to a race condition where the final value of count is less than the expected...
Compilers can reorder instructions for maximum throughput. Compilers won’t choose an ordering that changes the meaning of the code, but they assume that memory values are changed only when there are explicit instructions in the code. However, a memory value can be changed by another thread! If...
To better understand the usefulness of condition variables, let's look at an example where a group of workers are working on two tasks, A and B. Task B is dependent on Task A, meaning all workers must finish working on Task A before they can start working on Task B. ...
The remaining examples in this procedure assume you created a user called iswuser. To install a Sun Java System Directory Server Connector, you must choose a non-privileged port for the Connector during installation. For example, ports larger than 1024 are acceptable. Port 1389 is recommended ...
For the past several weeks I have been writing a synchronization library in my free time. This can be used in a distributed manner, meaning several nodes in a cluster can use this library to synchronize between each other. This implementation is based on Apache Zookeeper. Though primarily Zooke...

We assume that all the agents are introspective, meaning that they have access to their own local measurements. As a special case of heterogeneous MAS, we study state and regulated state synchronization of homogeneous MAS with non-introspective agents.Liu, Zhenwei...
Bvckup 2 is a backup/synchronization tool that uses "delta" copy methods, meaning it only transfers changes to a file or files rather than recopying the entire set. This is frequently faster, saves bandwidth for network backups and can help flash media live longer by reducing the overall num...
