So, I'm curious. Anyone have any major projects that people want before the end of the year?We have a business user that keeps asking for X fix, which I already have coded actually. But our SDLC requires the QA team to do thorough testing and none of them have the bandwidth until mid-January, which makes this a February release. None of which stops the BU from asking me if I can put the code into production NOW PLEASE.
What's worse is that he should know better given what impatience has done to his processes before. But some lessons just don't seem to stick.
When something goes into production, expedited and skipping some testing, who is to blame when there are issues?
Likely you, not the business.
So they usually end up with little risk in pushing to short circuit the process.
Business needs to make a case to support more resources at the bottleneck.
All too often, they expect IT to be doing this.
When they actually might be in a better position to quantify benefits to the business.
Hopefully they are part of the QA process, so the more they push, the more they end up being part of the resources needed to speed things up.
They selectively ignore requests for testing, never do the testing they're supposed to do and keep pushing for the production release. When things to awry, they don't know what happened or why things didn't work the way they wanted them to. It's just what they asked for, but not what they wanted. It isn't until later that they say they "didn't have time to test" with the deadline already here. Pay no attention to the fact that they were asking for quotes for new work when they were supposed to be testing.
This is one reason why I like to log *everything*.
User: "Hey, when's project wombat going live <bigwig> is asking I'll have to tell him the delay's with you"
Dev: "When you've tested it"
User: "Oh that's done"
Dev: "Funny that - the log says you've done none"
User "You're SPYING on us?!"
Dev: "Aye - I'd bear that in mind ... "

Trying another rephrase to see if I understand this correctly.So basically instead of creating multiple physical processors like memory makers create sticks of RAM, some bright soul thought to "weld" multiple processors into one "container" and hook them together. That way motherboards still only needed one (or two) slots for a CPU but servers and PCs could get the benefits of having multiple processors.
Yes? No? Maybe?
Actually, I wouldn't be surprised if that was about the thought process when the engineers came up with the first multi-core CPU...
So, yes, that's a pretty decent way to think of it.

I think it had a lot to do with proximity and speed of response. The closer the processors are to one another, the faster they can communicate with one another. If they're part of the same unit, they're very close and have no intermediary (the motherboard) between them to slow things down.

Don't confuse things with details!
:hehe:
But yes, interconnect speed likely played a very big part in the development of multi-cores. Imagine the difficulties in keeping 4+ single core CPUs in-sync when they're separated by a couple inches on the motherboard vs keeping them in-sync when they're only a couple fractions of a millimeter apart on a CPU die. Plus there would be cost savings from various things that could be shared between the cores, rather than having each reproduces on each CPU.

Not directly related, but something to maybe note.
Numa architecture in the machines kind of layers RAM in a similar fashion.
You may have 2 main banks, each tied to a socket. And specific memory (size and speed) optimized to work together.
So memory - and upgrade path - may be a consideration.
You may want to review some of the other licensing - especially for a virtual machine.
Host and how many cores - not what may be allocated to an instance - is the driver.
You can imagine the licensing true up costs, especially if you have multiple 8 or more core procs in a machine.
I liked the old licensing model better - it was much clearer and easier to understand.

(I think some of the L2 and L1 cache, various other bits and bobs)
Each core has it's own L1, at least with the Intel processors. L2 is 'shared' (kinda, one core can't flush the entire of L2), L3 if present as well.
Reason multiple cores is better than multiple processors is to do with the inter-core communication. With them really close together, there's less delay in communications between them.

I couldn't agree more if I tried. We're trying to gather licensing information now and it's to the point where the sales guy doesn't even know. He has an expert in SQL licensing he has to consult with every question I ask. They've made things unnecessarily complicated. One thing is certain...In the end, we'll pay more. It shouldn't have to be so complicated.

Unfortunately we're not going to get virtual machines this time around. Corporate doesn't have the design ready and we need the servers yesterday to respond to a vendor upgrade.
At least this time around we have a vendor upgrading before us instead of two years after us. That's got to count for something, right?

I ran into the same thing a few years ago.
I knew more than our Rep.
And corporate didn't listen to me, and heard a true up horror story after I left.
Here's a blast from the past -
remember how they used to market the processor based licensing as a competitive advantage?
and VM licensing too?

Always nice to have vendors supporting something more current.
VM's are good, but there is a learning curve.
Especially if you try to crowd too much onto them, and don't understand how to troubleshoot a performance issue.
VM's do offer some pretty good options for scaling and recovering.
So it is worth the learning curve.

Yes. Processor is the socket and cores is the number of cpus on the socket or that can fit in the socket. Cores are smaller, but to save space, it was easier to bring those cores together to fit in the same socket.
