A multi-phased multi-purpose micro-benchmark. The micro-benchmark is
|
||||
composed of 10 phases that perform various generic calculations (from
|
||||
memory to compute intensive).
|
||||
|
||||
It is a highly configurable tool which can be used for energy efficiency
|
||||
studies, ARM big.LITTLE Linux scheduler analysis and DVFS studies. It can
|
||||
be used for other benchmarking as well.
|
||||
|
||||
All floating-point calculations are double-precision.
|
||||
|
||||
| Phase 1: Floating-point & integer computations with good data locality
|
||||
| Phase 2: Vector multiplication & addition, 1 level of indirection in 1
|
||||
| source vector
|
||||
| Phase 3: Vector scalar addition and reductions
|
||||
| Phase 4: Vector addition
|
||||
| Phase 5: Vector addition, 1 level of indirection in both source vectors
|
||||
| Phase 6: Sparse matrix-vector multiplication
|
||||
| Phase 7: Linked-list traversal
|
||||
| Phase 8: Electrostatic force calculations
|
||||
| Phase 9: Palindrome calculations
|
||||
| Phase 10: Random memory accesses
|
||||
|
||||

||||

|
||||
|
||||
.. note:: current implementation of automation relies on the executable to
|
||||
be either statically linked or for all necessary depencies to be
|
||||
installed on the target.
