Actually not. Past the intial node. it is $100/node. So $3,025. That seems large until look at 30 x $1,199 ==> $35,970. So that is about 8.5% of the cost of the cluster. It is a bit high but in the single digit percentage of the "cost" of the cluster. If get more CPU cycles out of the part time Pooch grid than a dedicated $4,000 server running full time then it is a good value. If there are so few "excess" cycles that can't outcompute a $4,000 server then not.
I'll admit I was looking at the Pooch Pro license cost, which I think is the appropriate one for the functions that are being talked about.
It might be a good value, but it's a hell of a lot harder sell than "Free with OS X"
As I said before, this is far more about getting something for nothing ("free beer" and "off the IT radar" software acquisition) than about usability or features/value.
I don't think it is, any more than if Terminal.app was depreciated, and your only option was iTerm. It's not "something for nothing" - its something you were getting for free, core OS functionality that you may have built purchasing decisions on (indeed, XGrid was one of the major reasons I was considering a purely-Mac lab...) that went away rather abruptly.
I think dismissing that as "free beer" is disingenuous. It was an extended capability of the OS. It was a strength that made OS X decent for client-nodes. And yes, it was cheap, on an otherwise expensive hardware platform. It was also baked in and easy to use.
The new alternative is inherently not baked in, and generally speaking easy OR free.
$25/year would be about $2/month. That's pretty cheap. That's cheaper than what Amazon would charge for a single EC2 Linux node for 8 CPU days/mo.
Apples to Oranges.
I suspect Dauger Research charges so much for Pooch because folks buy it and then disappear for many years. So the number of paying customer per year is low.... so the unit price goes up. That generates a bad positive feedback loop pushing the unit costs up (or at very least stay constant over time).
I suspect its because they have very low unit sales and have to pay the bills. To be blunt, Macs are good enough client Machines in a Linux environment that for the most part, anyone seriously looking at doing this needs to be really dedicated not to go with a non-Apple hardware solution. Selling to a few die-hards (myself sometimes included) isn't a high volume business, even if you lower the price.
If primarily scavenging for cycles then something heterogeneous is better. If so broke can't pay for CPU cycles it is distinct disadvantage if can only get a small subset of the free cycles out there in the world. If there is a Windows PC CAD cluster down the hall XGrid does nothing with that.
There's a considerable excluded middle - notably the potential to essentially have dual-use machines that aren't purely cycle scavenging in the background, but aren't a dedicated cluster setup. For example, 4 or 5 Mac Pros in a lab that when the lights go off at 8 turn into a small cluster for longer running overnight jobs.
I suspect someone will either do some work to add Condor or Open Grid to macports (i.e., make it so there is an "easy default config install" ) or that some other either "free beer" project will pop up or a commercial one.
Macports itself is kind of in shambles, and its neither as easy nor as well supported as XGrid.
That's the thing. There are alternatives. But every time I go look at "alternatives", and ad-hoc projects and poorly supported ports, I start asking myself if the convenience factor of OS X is still there. Eroding convenience while keeping a price premium is, for at least me as a customer, a losing proposition.
There is always flux in applications the die off or come to market.
And if this was just random noise, it would be one thing. But we haven't had "good news" about scientific computing on a Mac for some time now. At a certain point, data becomes a trend.
The "bad website" is marginally better than no website. If folks keep bugging Apple about it seems likely they just take the whole set of pages down.
No, its not. A website talking about solutions that can no longer be obtained, with incorrect and obsolete documentation that gives the perception this is supported when its not *is worse* than no website at all.
At this point, if Apple releases new Mac Pros it will only be the "obsolete" ones that can run XGrid. If that is such a high value add then not so "obsolete".
"Don't worry, our ancient products can still use our depreciated software!" isn't a defense. And XGrid was a value add - it wasn't an infinite value add.
Select "processor generation" (as opposed to vendors) and hit submit. Between the 5500 and 5600 series that is more than 50% of all the top 500 supercomputers in the world. Really the majority of the world's supercomputers are obsolete? Not really.
Not the bleeding edge is different from being obsolete.
A Top 500 cluster is a vast, yawning gulf of infrastructure investment than a workstation, or even a group of workstations. The Mac Pro is obsolete. It just is. It's got an out of date processor, a laughably out of date graphics chip, and lacks essentially every major new I/O option out there (USB3, SATA3, Thunderbolt...) Far superior workstation models can be had from Apple's competitors right now.
Does that make a Top 500 cluster built off a 5500 or 5600 obsolete? No. Does it make it useless? Really, really no.
But I wasn't saying either one of those things.
