I am planning on getting back to a more regular cadence of writing. I enjoy it, and hopefully, I don’t annoy (all) readers. A brief retrospective on what has been over the last decade first. First, having experienced this first hand, its important to talk about the use pattern shifts. In 2010, cloud for HPC … Read more Whats coming in #HPC

For those who aren’t aware, I had written (a long, long time ago) a simple IO benchmark test, when I had been displeased with the (at the time) standard tools. Since then fio has come out and been quite useful, though somewhat orthogonal to what I wanted to use. The new results are at the … Read more Updated io-bm and results from system I was working on

Often times, when we are working on a project with a well defined set of milestones, we’ll be asked to add something to the list of tasks. These asks may be simple and quick, or long and time consuming. One thing each ask does, is increase the scoping of the milestone, increase the risk surface, … Read more On the importance of saying “no”

Its been a while, I know. My apologies. Ok, first off, I’ve been very busy at the $dayjob. More in a later post. But I’ve been doing some code fix up for a number of my tools, specifically the net-tools collection. This one had nagged me a long time. Ok, here it is in a … Read more Updated net-tools with fixes and license change

I have to be quite careful to not discuss $dayjob stuff here. Which, as that consumes a large chunk of my daytime (a bit more than 8h/day), leaves me with precious little time for me. But I enjoy this position, and the company. It is nice to be part of an organization that values (deep) … Read more Apologies for the long delay in posting

I learned today, of the HPE Greenlake flex system. It has a nice infographic which describes it. What struck me, was that this was a model very similar to something I had worked on in 2014-2015, that I had been trying to raise capital to execute against, at Scalable Informatics (RIP). The question the VCs … Read more When you see someone deploying a business model very similar to one you had developed on your own …

We’ve seen issues in the past, with massive flooding in Thailand, wreaking havoc on critical components in supply chains. The subsequent demonstration of the basic economics laws of supply and demand did not make users or vendors very happy. This arose due to a significant over-allocation of one small geographical region to a critical component … Read more Length and complexity of supply chain as a risk factor for HPC and storage

So I’m playing with Julia in my off time to get more proficient with it. Doing some “simple” things in preparation for the work I want to do. One of the things I like to play with are environments linear algebra capabilities. This was one of my favorite areas as an undergraduate (cringe) years ago, … Read more Slightly more complexity than I had thought, or RTFM!

Ok, this came about from many hours … HOURS … of not being able to get rescue CD images to boot correctly on my laptop, or in VMs. Things were broken on them, that I could not fix. That’s when the thought occurred to me … hey … I’d developed this great project nyble (pronounced … Read more Nyble FTW! Installing my rambooted environment on linux laptop for rescue with grub

I’ve got a pair of Samsung 28 inch 4k monitors that I use for my daily environment. I have 3 (actually 4) machines to share them between, 2(3) linux boxen and 1 Mac laptop. In my original design, pre-KVM switch, I had one monitor dedicated to the Mac, and one switched with the annoying little … Read more displayport KVMs for sharing monitors and keyboards
