“…We have observed that the I/O problem has indeed been addressed in modern database engines, and that memory system performance is already the main bottleneck. Perl and Sites [14] study Microsoft SQL Server performance on an Alpha-based Windows NT server through trace-driven simulation. They claim that OLTP performance is mostly limited by chip pin bandwidth, since the bandwidth that would be required to maintain a CPI of 1 in the Alpha 21164 would be much greater than what is available in that processor.…”

“…Yet, current processors have been primarily optimized to perform well on the SPEC95 [18] benchmark suite. Similarly, design of multiprocessor architectures, along with academic research in this area, have been heavily influenced by popular scientific and engineering benchmarks such as SPLASH-2 [26] and STREAMS [13], with only a handful of published architectural studies that have in some way tried to address issues specific to commercial workloads [3,7,9,12,14,16,20,21,24].…”

Commercial applications such as databases and Web servers constitute the largest and fastest-growing segment of the market for multiprocessor servers. Ongoing innovations in disk subsystems, along with the ever increasing gap between processor and memory speeds, have elevated memory system design as the critical performance factor for such workloads. However, most current server designs have been optimized to perform well on scientific and engineering workloads, potentially leading to design decisions that are non-ideal for commercial applications. The above problem is exacerbated by the lack of information on the performance requirements of commercial workloads, the lack of available applications for widespread study, and the fact that most representative applications are too large and complex to serve as suitable benchmarks for evaluating trade-offs in the design of processors and servers. This paper presents a detailed performance study of three important classes of commercial workloads: online transaction processing (OLTP), decision support systems (DSS), and Web index search. We use the Oracle commercial database engine for our OLTP and DSS workloads, and the AltaVista search engine for our Web index search workload. This study characterizes the memory system behavior of these workloads through a large number of architectural experiments on Alpha multiprocessors augmented with full system simulations to determine the impact of architectural trends. We also identify a set of simplifications that make these workloads more amenable to monitoring and simulation without affecting representative memory system behavior. We observe that systems optimized for OLTP versus DSS and index search workloads may lead to diverging designs, specifically in the size and speed requirements for off-chip caches.

“…Perl and Sites [14] demonstrated that both high bandwidth and low latency are required to effectively run OLTP and other commercial applications. Their experiments assumed single-cycle instruction latencies and on-chip cache sizes of the Alpha 21064 (8KB I, 8KB D) and 21164 (8KB I, 8KB D, and 96KB unified on-chip L2).…”

Using generational garbage collection to implement cache-conscious data placement

The cost of accessing main memory is increasing. Machine designers have tried to mitigate the consequences of the processor and memory technology trends underlying this increasing gap with a variety of techniques to reduce or tolerate memory latency. These techniques, unfortunately, are only occasionally successful for pointer-manipulating programs. Recent research has demonstrated the value of a complementary approach, in which pointer-based data structures are reorganized to improve cache locality. This paper studies a technique for using a generational garbage collector to reorganize data structures to produce a cache-conscious data layout, in which objects with high temporal affinity are placed next to each other, so that they are likely to reside in the same cache block. The paper explains how to collect, with low overhead, real-time profiling information about data access patterns in object-oriented languages, and describes a new copying algorithm that utilizes this information to produce a cache-conscious object layout. Preliminary results show that this technique reduces cache miss rates by 21-42%, and improves program performance by 14-37% over Cheney's algorithm. We also compare our layouts against those produced by the WilsonLam-Moher algorithm, which attempts to improve program locality at the page level. Our cache-conscious object layouts reduces cache miss rates by 20-41% and improves program performance by 18-31% over their algorithm, indicating that improving locality at the page level is not necessarily beneficial at the cache level.
