    strace for Fun and Profit Introducing an strace analyzer. Also using strace to examine some ISV codes OK, I Wrote an strace Analyzer Using strace to look at the IO pattern of codes, particularly for MPI codes makes my life a lot easier. I use strace to examine the bandwidth of read and write functions...
  • 5-27-2008 - HPCC is the Fastest Growing Sector of IT - Comments

    HPCC is Fastest Growing Sector of IT Who would have thought? HPCC is Fastest Growing Sector of IT Just a quick blog (really a note) that HPC is now recognized as the fastest growing sector of IT. This article from eWeek points out that HPC is was a $11.5 Billion per year business in 2007 and is growing...
  • HPC Cluster Storage

    For many years people viewed storage as kind of an afterthought in the design of clusters. But over time as HPCC has grown and taken on an increasingly important role in companies' overall strategy, storage has become much more important and is usually designed into the cluster from the beginning...
  • 11-24-2008 - Tiering Your Data

    In the past, I’ve talked about ways you can learn about the IO patterns of your applications. Once you know the characteristics of the IO pattern of your applications, you can start to think about how to construct your storage solution from the perspective of performance and capacity requirements...
  • 01-07-2009 - Things You Didn’t Know About Solid State Disks (SSD’s)

    I’m sure pretty much everyone has heard about SSDs. They are the current technology rave in storage. They have, as their name suggests, no moving parts. They use NAND for storing data, much like flash drives . What makes them so attractive is: They have no moving parts, so you can drop them without...
  • 02-18-2009 - Great Tips on SSDs

    There is a new article at PC Perspective that talks about the really hot Intel SSDs. But it goes beyond a normal review and gets into some of the guts of SSDs and talks about an important topic: file system performance as it ages. So, I want to write about the review and point out the file system aging...
  • 04-08-2009 - Nehalem and Memory Configurations

    The Intel® Xeon® processor 5500 series architecture (code named, "Nehalem")–based systems bring a whole new level of memory bandwidth to the high-performance computing (HPC) party. But the new architecture brings with it some options that allow you to trade memory price, memory...

Last September, CASC had its 20th anniversary meeting . Academic and industry leaders gathered in Washington DC to discuss...
  • Changing BIOS settings with syscfg from the DTK

    If you find yourself in need of a tool that can change BIOS settings while you are still booted into the operating system, look no further. syscfg is a powerful tool provided by DTK (Dell Toolkit) that allows you to do just that. This article will cover using syscfg to change the number of CPU cores...

    Introduction by Dell's Dr. Jeff Layton Dr. Jeff Layton Dell Enterprise Technologist HPC Everyone is probably aware that the amount of computational power in HPC is growing at a tremendous rate. Problem sizes are growing, fidelity of the models is improving, more difficult...
  • HPC Tech Tip: Updating your compute nodes firmware via PXE - 03-12-2010

    Introduction If you find yourself having to update any firmware on your servers via DOS, instead of walking to each server and using a USB drive, or booting to a USB floppy, try it via PXE. In most cases we have a Linux based update package, so you can avoid updating in this manner. I am assuming that...
  • A Comparison of Ext2, Ext3 and Ext4 Performance

    The goal of this post is to study the sequential read and write performance that one can get from a RAID array using various local file systems available in Linux, specifically the ext2, ext3 and ext4 file systems. Ext3 file system adds journal feature to ext2 for better reliability. Ext4 is an incremental...
  • PetaFLOPS for the Common Man- Pt 5 Challenges with PetaFLOPS scale systems

    I think it’s fairly safe to say that so far PetaFLOPS class systems will be more fairly straight-forward to build in the next three years or so. The processing part of the problem, whether it be from CPUs or a hybrid of CPUs and GPUs, is gaining a fair amount of momentum and in 3 years we should...
  • Comparing Different PV MD1200 Connection Topologies

    The Dell PowerVault MD1200/1220 arrays provide a convenient way to expand the PowerEdge servers to gain access to more drives. The MD1200 and MD1220 models use the 6Gb SAS technology, and they can be daisy chained up to 4 units. This allows a maximum of 8 arrays to be connected to a single adapter since...

  • Architecting HPC Systems for Fault Tolerance and Reliability Part 7- Login Head Nodes

    Typically, clustered HPC systems have at least one node that is dedicated to handling logins from individual users of the system. From here, users manipulate their data, submit jobs into the system, and track status of their running jobs. Login nodes are generally not extremely critical to continued...
  • Seeking Nominations for HPC Advisory Council Awards at ISC’10

    The HPC Advisory Council is asking all HPC hardware and software vendors and end-users to nominate their choice for the four 2009-2010 HPC Advisory Council Awards.

  • Architecting HPC Systems for Fault Tolerance & Reliability Part 8- Compute Nodes

    The real work of an HPC cluster happens on the compute nodes. Most of the other subsystems in a cluster are there to support the computational needs of the compute nodes. It might be a little surprising then, to find out then that the compute nodes generally require very little in the way of fault tolerant...
