Question

Question: 6.17 Benchmarking is field of study that involves identifying representative workloads to run on specific computing platforms in order to be able to objectively compare performance of one system to another. In this exercise we will compare two classes of benchmarks: the Whetstone CPU benchmark and the PARSEC Benchmark suite. Select one program from PARSEC. All programs should be freely available on the Internet. Consider running multiple copies of Whetstone versus running the PARSEC Benchmark on any of systems described in Section 6.11.

6.17.1 [60] what is inherently different between these two classes of workload when run on these multi-core systems?

6.17.2 [60] In terms of the Roofline Model, how dependent will the results you obtain when running these benchmarks be on the amount of sharing and synchronization present in the workload used?

Short answer

6.17.1

The two differences between these two suites:

• Whetstone

• PARSEC

6.17.2

The benchmark of the “PARSEC” should be only impacted by the synchronization and the sharing.

Step-by-step solution

Define the concept.

6.17.1

Whetstone is referred to a test of the benchmark whose purpose is for measuring the performance of the floating-point operations in the computer. The performance is computed by calculating the speed and the efficiency. The outcome of the test is provided in "KWIPS" units. This unit is known as also the "kilo-whetstones-per-second".

6.17.2

The "PARSEC" is referred to as a benchmark suite. The purpose is to study the "CMPs". These “Cmps” are basically Chip-Multiprocessors. This suit is also including mining and synthesis. Also, the emerged applications in recognition are included with this. One of the characteristics of this is to cover the broad spectrum of data sharing, synchronization working sets, locality, and so on.

Determine the calculation.

6.17.1

The first difference describes the design for the performance of the floating point. And the second one is for the workloads of those, which are determined by the programs of multithread. The purpose of whetstone is for measuring the performance of the floating-point operations in the computer. The performance is computed by calculating the speed and the efficiency. The outcome of the test is provided in "KWIPS" units. This unit is known as also the "kilo-whetstones-per-second".

6.17.2

The benchmark of the “PARSEC” should be only impacted by the synchronization and the sharing. But this should not be a factor of the “Whetstone”. The purpose of the "PARSEC” is to study the "CMPs". These “Cmps” are basically Chip-Multiprocessors. This suit is also including mining and synthesis. Also, the emerged applications in recognition are included with this. One of the characteristics of this is to cover the broad spectrum of data sharing, synchronization working sets, locality, and so on.
