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)
