Intra-disk Parallelism: An Idea Whose Time Has Come
2008
2008 International Symposium on Computer Architecture
Preserved Fulltext
We find that rotational latency is the primary bottleneck that intra-disk parallelism needs to optimize. • We present an intra-disk parallel design, which involves the use of multiple disk arm assemblies ...
We discuss about the multi-actuator drives that were used in mainframes back in the 1970s and 80s, why they were discontinued, and show why our intra-disk parallelism idea is different. • We present a ...

The system has the full functionality of a DBMS. It is neither, as indicated above, a distributed file system, nor is it a transaction processing system. ...
Parallelism can increase throughput (using inter-query parallelism) and decrease transaction response times (using intra-query and intra-operation parallelism). ...
Intra-operation parallelism is achieved by executing an operation on several nodes of a multiprocessor machine. ...

Current DBC solutions for OLAP query processing provide for intra-query parallelism only, at the cost of full replication of the database. ...
We also propose a new load balancing strategy that takes advantage of an adaptive virtual partitioning to redistribute the load to the replicas. ...
Each one has already been employed in isolation for intra-query parallelism implementation during OLAP query processing. ...
