+Dynamic Load Balancing Library
+DLB is a dynamic library designed to speed up HPC hybrid 
+applications (i.e., two levels of parallelism) by improving the load balance of the outer 
+level of parallelism (e.g., MPI) by dynamically redistributing the computational resources 
+at the inner level of parallelism (e.g., OpenMP). at run time. This dynamism allows DLB to 
+react to different sources of imbalance: Algorithm, data, hardware architecture and 
+resource availability among others.
+
+Lend When Idle LeWI (Lend When Idle) is the algorithm 
+used to redistribute the computational resources that are not being used from one process 
+to another process inside the same shared memory node in order to speed up its execution. 
+
+Dynamic Resource Ownership Manager
+DROM (Dynamic Resource Ownership Manager) is the algorithm used to manage the CPU affinity of a process running a shared memory programming model (e.g., OpenMP)
