Beowulf List

Don't have time to read the Beowulf List Archives. No problem, our resident List Lurker (and contributor) Jeff Layton has you covered. Our Best of the Beowulf List column provides a convenient readers Digest Version with important links!

Grids, disks, directories, and Weird OS tricks (wheee!)

Jeff visits a few other lists in search of cluster goodies

The Beowulf mailing list provides detailed discussions about issues concerning Linux HPC clusters. In this column I report on using semi-public PC's for grid type applications and how we can handle large numbers of files. We also turn to the ganglia-developers mailings list to report on how one can add a "disk alive" metric to ganglia. You can consult the Beowulf archives, the bioclusters archives, and the ganglia archives for the actual conversations.

Cluster Cooling, Noise and Benchmark Timing

The Beowulf mailing list provides detailed discussions about issues concerning Linux HPC clusters. In this column I report on some popular infrastructure issues as well as some benchmarks for beowulfs. You can consult the Beowulf archives for the actual conversations.

SATA drives, benchmarks, booting from USB

Wisdom of the ages ...

The Beowulf mailing list provides detailed discussions about issues concerning Linux HPC clusters. In this column I report on Serial ATA (SATA) drives , I/O benchmarks, cluster benchmarks, and booting from solid state USB drives. You can consult the Beowulf archives for the actual conversations.

Grids, Ganglia Metrics, IO, and UML

The Beowulf mailing list provides detailed discussions about issues concerning Linux HPC clusters. In this column we turn our attention to the bioclusters mailing list where we report on using semi-public PC's for grid type applications and how we can handle large numbers of files. I also turn to the ganglia-developers mailings list to report on how one can add a "disk alive" metric to ganglia. You can consult the Beowulf archives or the Biocluster archives

Cluster Noise and Clock Resolution

In this installment of the Best of the Beowulf Mailing List we review some postings about noise issues (always a problem) and clock resolution for code profiling. You can consult the archives for the actual conversations.

Beowulf: Quiet and Powerful

If you have stood next to a rack of 1U dual processor computers you know how loud they can be. On December 12, 2003, Joshua Baker-LePain asked about systems that provided the best bang for the noise (performance per dB anyone?). He currently has six 1U nodes with dual 2.4 GHz Xeon processors in them. Each node has eleven small fans, resulting in a setup that was very loud for the people around them (and there were people in the same room as the machines). He is looking for systems that are much quieter but without a penalty in speed. Nicholas Henke was the first to respond that his desktop Dell 650N box was very quiet and it was a dual processor machine.
