I’m attending SC18 next week. It’s been 3 years since I last attended (2015). Then we (@scalableinfo) had a large booth, lots of traffic, and showed off some of the first commercial NVMe high performance storage systems running BeeGFS over 100GbE. I am looking forward to talking with as many people as I can, to … Read moreLooking forward to #SC18 next week and a discussion of all things #HPC
There are a set of modules in the Perl universe that I’ve been looking for an excuse to use for a while. They are the MCE set of modules, which purportedly enable easy concurrency and parallelism, exploiting many core CPUs, and a number of techniques. Sure enough, I had a task to handle recently that … Read moreFinally got to use MCE::* in a project
Way back in the pre-history of the internet (really DARPA-net/BITNET days), while dinosaur programming languages frolicked freely on servers with “modern” programming systems and data sets, there was a push to go from a static linking programs to a more modular dynamic linking. The thought processes were that it would save precious memory, not having … Read moreWhat is old, is new again
This is something we’ve been working on for a while … a completely clean, as baseline a distro as possible, version of our SIOS RAMdisk image using CentOS (and by extension, Red Hat … just need to point to those repositories). And its available to pull down and use as you wish from our download … Read moreFully RAMdisk booted CentOS 7.2 based SIOS image for #HPC , #bigdata , #storage etc.
While the day job builds (hyperconverged) appliances for big data analytics and storage, our partners build the tools that enable users to work easily with astounding quantities of data, and do so very rapidly, and without a great deal of code. I’ve always been amazed at the raw power in this tool. Think of a … Read moreRaw Unapologetic Firepower: kdb+ from @Kx
We’ve got customers with very large resource machines. And software that sees all those resources and goes “gimme!!!!”. So people run. And then more people use it. And more runs. Until the resources are exhausted. And hilarity (of the bad kind) ensues. These are firedrills. I get an open ticket that “there must be something … Read moreWhen infinite resources aren't, and why software assumes they are infinite
An article appeared on HN this morning. In it, the author noted that all was not well with the universe, as their backup, using Amazon’s Glacier product, wound up being quite expensive for a small backup/restore. The OP discovered some of the issues with Glacier when they began the restore (not commenting on performance, merely … Read more"Unexpected" cloud storage retrieval charges, or "RTFM"
In Feb 2013, I opined (with some measure of disgust) that people were looking at various software packages as silver bullets, these magical bits of a stack which could suddenly transform massive steaming piles of bits (big … uh … “data” ?) into golden nuggets of actionable data. Many of the “solutions” marketed these days … Read moreThere are no silver bullets, 2015 edition
So far, 3 components, and working to fix a few things in formatting. On github, grab it here. First, lsbond.pl to report about bond details root@unison-mgr-1:~/net-tools# ./lsbond.pl bond0: mac 0c:c4:7a:48:69:cb state up mode fault-tolerance (active-backup) xmit_hash layer2 0 active slave eth1 polling 100 ms up_delay 200 ms down_delay 200 ms slave nics: eth1: mac 0c:c4:7a:48:69:cb, … Read moreUpdated net-tools bits
This is a very exciting hyper-converged system, representing our next generation of time series, and big data analytical systems. Tremendous internal bandwidths coupled with massive internal parallelism, and minimal latency design on networks. This unit has been designed to focus upon delivering the maximal performance possible in an as minimal footprint … both rack based … Read moreThe worlds fastest hyper-converged appliance is faster and more affordable than ever
