Put my Riemann Zeta Function sum reduction code on github
Repo is here: https://github.com/joelandman/rzf. There’s a lightning talk to go along with it, and I’ll make sure I can get it together for this as well.

I’ve not heard of aria2c before today. Sort of a super wget as far as I could tell. Does parallel transfers to reduce data motion time, if possible. So I pulled it down, built it. I have some large data sets to move. And a nice storage area for them. Ok. Fire it up to … Read moreAria2c for the win!

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
Though, when I look at the “great speed”, it is often on par with or less than Scalable Informatics sustained years before. From 2013 SC13 show, on the show floor, after blasting through a POC at unheard of speed, and setting long standing records in the STAC-M3 benchmarks … Article in question is in the … Read moreI always love these breathless stories of great speed, and how VCs love them …
Way way back in the early aughts (2000’s), we had built a set of designs for an accelerator system to speed up things like BLAST, HMMer, and other codes. We were told that no one would buy such things, as the software layer was good enough and people didn’t want black boxes. This was part … Read moreBrings a smile to my face … #BioIT #HPC accelerator
For a partner. They made a request for something we’ve not built in a while … it had been end of lifed. One of our old Pegasus units. A portable deskside supercomputer. In this case, a deskside franken-computer … built out of the spare parts from other units in our lab. It started out as … Read moreHows this for a nice deskside system … one of our Cadence boxen
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
Most people use squashfs which creates a read-only (immutable) boot environment. Nothing wrong with this, but this forces you to have an overlay file system if you want to write. Which complicates things … not to mention when you overwrite too much, and run out of available inodes on the overlayfs. Then your file system … Read morenew SIOS feature: compressed ram image for OS
TL;DR version: 10GB/s write, 10GB/s read in a single 2U unit over 100Gb network to a backing file system. This is tremendous. The system and clients are using our default tuning/config. Real hyperconvergence requires hardware that can move bits to/from storage/networking very quickly. This is that. These units are available. Now. In volume. And are … Read moreNot even breaking a sweat: 10GB/s write to single node Forte unit over 100Gb net #realhyperconverged #HPC #storage
