</div>
<div style="font-family: Consolas; font-size: medium;">================================</div>
<div style="font-family: Consolas; font-size: medium;"><br>
</div>
<div style="font-family: Consolas; font-size: medium;">The objective of the WBDB workshops is to make progress towards</div>
<div style="font-family: Consolas; font-size: medium;">development of industry standard application-level benchmarks</div>
<div style="font-family: Consolas; font-size: medium;">for evaluating hardware and software systems for big data applications.</div>
<div style="font-family: Consolas; font-size: medium;"><br>
</div>
<div style="font-family: Consolas; font-size: medium;">Discussions from previous WBDB workshops have resulted in the formation of</div>
<div style="font-family: Consolas; font-size: medium;">the TPC-BigData subcommittee, which is currently</div>
<div style="font-family: Consolas; font-size: medium;">working on the TPCx-HS benchmark, for Hadoop Systems. There have also been</div>
<div style="font-family: Consolas; font-size: medium;">presentations on a variety of proposed benchmarks</div>
<div style="font-family: Consolas; font-size: medium;">including, BigBench, HiBench, BigDataBenchmark, BigDecision, and the Deep</div>
<div style="font-family: Consolas; font-size: medium;">Analytics Pipeline.</div>
<div style="font-family: Consolas; font-size: medium;"><br>
</div>
<div style="font-family: Consolas; font-size: medium;">Meeting Topics:</div>
<div style="font-family: Consolas; font-size: medium;">To continue making progress towards big data benchmarking standards, the</div>
<div style="font-family: Consolas; font-size: medium;">workshop will explore a range of issues including:</div>
<div style="font-family: Consolas; font-size: medium;">- Data features: New feature sets of data including, high-dimensional</div>
<div style="font-family: Consolas; font-size: medium;">data, sparse data,</div>
<div style="font-family: Consolas; font-size: medium;"> event-based data, and enormous data sizes.</div>
<div style="font-family: Consolas; font-size: medium;">- System characteristics: System-level issues including, large-scale and</div>
<div style="font-family: Consolas; font-size: medium;">evolving system configurations,</div>
<div style="font-family: Consolas; font-size: medium;"> shifting loads, and heterogeneous technologies for big data and cloud</div>
<div style="font-family: Consolas; font-size: medium;">platforms.</div>
<div style="font-family: Consolas; font-size: medium;">- Implementation options: Different implementation options such as SQL,</div>
<div style="font-family: Consolas; font-size: medium;">NoSQL, Hadoop software ecosystem,</div>
<div style="font-family: Consolas; font-size: medium;">and different implementations of HDFS.</div>
<div style="font-family: Consolas; font-size: medium;">- Workloads: Representative big data business problems and corresponding</div>
<div style="font-family: Consolas; font-size: medium;">benchmark implementations. Specification</div>
<div style="font-family: Consolas; font-size: medium;"> of benchmark applications that represent the different modalities of big</div>
<div style="font-family: Consolas; font-size: medium;">data, including graphs, streams,</div>
<div style="font-family: Consolas; font-size: medium;"> scientific data, and document collections.</div>
<div style="font-family: Consolas; font-size: medium;">- Hardware options: Evaluation of new options in hardware including</div>
<div style="font-family: Consolas; font-size: medium;">different types of HDD, SSD, and main memory,</div>
<div style="font-family: Consolas; font-size: medium;"> and large-memory systems, and new platform options that include</div>
<div style="font-family: Consolas; font-size: medium;">dedicated commodity clusters and cloud platforms.</div>
<div style="font-family: Consolas; font-size: medium;">- Synthetic data generation: Models and procedures for generating</div>
<div style="font-family: Consolas; font-size: medium;">large-scale synthetic data with requisite properties.</div>
<div style="font-family: Consolas; font-size: medium;">- Benchmark execution rules: E.g. data scale factors, benchmark versioning</div>
<div style="font-family: Consolas; font-size: medium;">to account for rapidly evolving workloads</div>
<div style="font-family: Consolas; font-size: medium;"> and system configurations, benchmark metrics.</div>
<div style="font-family: Consolas; font-size: medium;">- Metrics for efficiency: Measuring the efficiency of the solution, e.g.</div>
<div style="font-family: Consolas; font-size: medium;">based on costs of acquisition, ownership,</div>
<div style="font-family: Consolas; font-size: medium;"> energy and/or other factors, while encouraging innovation and avoiding</div>
<div style="font-family: Consolas; font-size: medium;">benchmark escalations that favor large</div>
<div style="font-family: Consolas; font-size: medium;"> inefficient configuration over small efficient configurations.</div>
<div style="font-family: Consolas; font-size: medium;">- Evaluation frameworks: Tool chains, suites and frameworks for evaluating</div>
<div style="font-family: Consolas; font-size: medium;">big data systems. </div>
<div style="font-family: Consolas; font-size: medium;">- Early implementations: E.g. of, say, BigBench, HiBench,</div>
<div style="font-family: Consolas; font-size: medium;">BigDataBenchmark, BigDecision, and the Deep Analytics</div>
<div style="font-family: Consolas; font-size: medium;"> Pipeline, and lessons learned in benchmarking big data applications.</div>
