Lockless-MiniSPLASH2 is a lock-free version of part of the
Stanford Parallel Applications for Shared Memory.
In this version most lock-based data structures used by
the original SPLASH-2
were replaced by non blocking synchronisation
The SPLASH-2 suite of parallel applications has been developed
to facilitate the study of centralised and distributed and
shared-address-space multiprocessor systems and has been used
extensively by the parallel architecture community.
We developed the Lockless-MiniSPLASH2 together with the
Lockless-Spark98 Kernels in order to:
facilitate the understanding of the benefits of non-blocking
synchronisation in realistic and simple parallel codes,
expected to play a central role in many parallel
facilitate the understanding of
using nonblocking synchronisation instead of using lock-based
one when building cache coherent shared memory
The source code of Lockless-MiniSPLASH2 is based on the SPLASH-2 suite of parallel applications and
the modified part is developed under the
