Fourth quarterly meeting of 2009 November 17th, 2009
Presentation
Abstracts
Reducing Java Garbage
Collection Pause Times A common issue with
getting Java applications to adhere to service level response time
agreements is taming the garbage collection pause time. This paper
examines ways to reduce the pause time, mentioning various options that
are helpful in this regard. In addition, this paper covers the
Concurrent Mark-Sweep collector and the new Garbage First collector,
both of which perform collections without pausing the application.
Load Testing on a
Budget, Part II An earlier paper provided
a introductory tutorial on using the open-source tool JMeter to load
test a web application. But that paper just scratched the surface of
what JMeter is capable of. This paper continues where that paper left
off, describing how you can make use of some of the other capabilities
of JMeter to load test applications. This paper is provided as a
tutorial giving specific steps to accomplish various tasks.
Improving z/OS Capacity and
Performance with Parallel Sysplex Parallel Sysplex has been an integral part of z/OS systems for over a decade - primarily to improve the availability of systems and applications. Many smaller z/OS installations without stringent availability requirements have not implemented Sysplex. This paper takes a look at using the Parallel Sysplex Resource Sharing and the Coupling Facility technology to improve the performance and throughput of z/OS systems and applications without increasing the MIPS or MSUs of the processing complex.
Performance Computing Cluster on
Commodity Hardware
High Performance Computing (HPC) Cluster
implementation at Saint Louis University will be discussed. This session
will review how we built an HPC using commodity hardware, explore the
issues and pitfalls, review hardware architecture, overview the
extensive open source software and applications available.
We will look at the batch-queuing system SLU selected (Sun Grid
Engine). Power and cooling concerns will be discussed.
InfiniBand and Lustre file system will be briefly touched upon.
We will also look at some of the free tools presented by Adrian
Cockcroft at the last STL-CMG meeting as applied to HPC.
Costs will be presented. This session will conclude with some of
the future enhancements we are looking at including SSD (sold state
disks) and High Throughput Computing (HTC).
