This line in that post is mystifying: they peddled Infiniband, an inferior design based on bus technology, but repositioned as a point to point network
At least initially (~2005 or so?) we had customers who were given free IB for their HPC clusters ripping the IB out and replacing it with with paid Myrinet installations because they could never get their IB clusters to work reliably. Although we had the superior product, we could not market our way out of a wet paper bag. Our CEO counted on our (then) superior engineering & expected our products to market themselves…
unless I'm thinking of the wrong vendor, the myrinet devices supported programming the nic. for some applications that was a really big win over IB verbs

> The CEO capped the full time headcount at 49 people so he wouldn’t be subject to California law requiring him to provide his employees with a health plan. Can you imagine being this stingy and short sighted? The employees are largely PhDs and he is willing to cripple his company to avoid paying benefits.
I can totally imagine not wanting the hassle of my company having to be a health insurance broker in addition to its actual purpose. What's wrong with paying employees a good salary and having them be responsible for their own insurance, any more than having them buy their own food, housing, and transportation?

I believe this was disputed by a former employee elsewhere ITT.

I believe that There are many things that kick in at 50 people. It's oversimplifying to assume this was due to not wanting to offer benefits. First google hit: https://www.aeisadvisors.com/california-compliance-is-my-com...
Why 50? Isn’t that arbitrary? Why not just force benefits for all employees? At least target revenue, if a company makes X revenue it has to provide Y benefits per employee. CEOs definitely won’t be able to easily make the decision to take in less money, as that will piss off share holders.
It is arbitrary, but we have to draw the line somewhere.
It is not about money, tax is about money. This is about the extra work needed to accommodate for said obligations, it can involve several full time jobs, and the state considers that it is too much for a company of less than 50 employees.
Really, it is a lot of paperwork, and the more a company spends on paperwork, the less there is to pay employees.

#106I worked for Myricom 2001->2013, and Google 2013->2015. And, wow, I wish I could comment on this thread.. :) EDIT: Scott's Medium blog post linked from this article is fascinating: https://medium.com/swlh/myricom-an-hpc-story-and-lessons-lea...
Correct me if I'm wrong, but Lanai was designed by Jakov. Who sadly and unexpectedly passed away a few weeks ago.

> Why not just force benefits for all employees? Public perception. Small business owners occupy a different perceptual space than large businesses. Lawmakers don't want to be perceived as hurting small businesses and craft laws to avoid it. It's more about maintaining political power as much as anything else.
I thought of this too, and it’s actually good system. Those small businesses should be exempt I think. It’s only the large corporations that should be forced to pay (I wouldn’t even be opposed to subsidizing health care for those businesses by taxing larger ones more.)
I think a system where we go by revenue is a lot of logical than going by number of employees. If a business makes 1Bpy but only has two employees, would it not be exempt from the current regulations?

Downvotes are fickle things. Unrelated, why turn down the health care? With double health care you can tell you're health provider you've got double coverage and they will bill the primary first, and then the secondary for what is left (and if the secondary is designed to be a primary program it will cover all that is left so you end up with zero out of pocket, even for co-payments).
I don’t know if it’s illegal, but basically every health care plan will deny you if they know you have other coverage. This is bad advice.
You’re wrong. It is perfectly common to have double coverage. I had it on multiple occasion. You can read about it if you google “coordination of benefits”.

Yes and no. The original firmware / host driver stack was open (shared?) source called MyriAPI. It was so terrible that spawned an ecosystem of uni and research lab projects to implement replacements. I worked on one such project at Duke (Trapeze). Others included BIP, Fast Messages, Active Messages.
MyriAPI was later replaced by a new firmware / host stack called GM. I think at some point we stopped shipping firmware source. I think that point was the transition from MyriAPI to GM...
