Below is what I found about compute bound.
Makes perfect sense to me.
I do understand about this stuff, how everything going around the big
circle has to match up, front side bus, video sub system, and
considering we're still using bios based systems instead of efi like
the rest of the modern computing world, it's a wonder this stuff runs at all.
With the apps I use, timing and latency and optimizing a machine for
audio performance means you have to be aware of what the hardware is doing.
So this was an easy one smart guy, try again.
And Jeff, you can blow it out your ear too, just because you can
crunch a bit of code and make win-amp do a dance, doesn't make you
the smartest guy in the world either.
YOu told me yourself you weren't a hard-ware guy, some of you guys
who flap code couldn't put a drive in or seat a processor or even put
in memory.
yourself,
Much less install your os from scratch,
so feel smug, you'll be paying someone $100 an hour to fix your
machine when it breaks, and I'll happily fix my own.
If this is what being a nerd is about, I'm glad I'm a music man and
not a full time computer guy, these cats can't stand any criticism or
any one giving a challenge.
Or someone expressing their needs to be met.
No wonder window-eyes lags so far behind.
Are these clowns the best we got?
Wow, I'm impressed.
But I'll keep trying as long as I've got anything invested.
A couple of jerks don't make the whole pile bad.
, CPU bound (or compute bound
) is when the time for a
computer
to complete a task is determined principally by the speed of the
central processor
: processor utilization is high, perhaps at 100% usage for many
seconds or minutes.
Interrupts
generated by
peripherals
may be processed slowly, or indefinitely delayed.
The concept of CPU bound was developed during early computers, when
data paths between
computer components were simpler, and it was possible to visually see
one component
working while another was idle. Examples components were CPU, tape
drives, hard disks,
card-readers, and printers. Computers that predominantly
used peripherals were characterized
as
I/O bound
. Establishing that a computer is frequently CPU bound implies that
upgrading the
CPU or optimizing code will improve the overall computer performance.
With the advent of multiple busses, parallel processing,
multiprogramming
,
preemptive
scheduling, advanced
graphics cards
, advanced
sound cards
and generally, more decentralized loads, it became less likely to
identify one particular
component as always being a
bottleneck
. It is likely that a computer's bottleneck shifts rapidly between
components. Furthermore,
in modern computers it is possible to have 100% CPU utilization with
minimal impact
to another component. Finally, tasks required of modern computers
often emphasize
quite different components, so that resolving bottleneck for one task
may not affect
the performance of another. For these reasons, upgrading a CPU does
not always have
a dramatic effect. The concept of being CPU bound is now one of many
factors considered
in modern computer performance.

Well, I have read your two posts and your words make your lips sound
like a flapping flat tire. Not sure what your expertise is but one
thing I know is that you do not have any more of an investment in GW
Micro than anyone else on this list so why do you think you are so
special as to feel an entitlement. The software business is not an
easy one and I feel you and a few others on this list have no idea
of how difficult things can be in this bad economic time. And to
your point about 32 bit verses 64 bit and what GW micro did or
didn't do. Gw Micro realized that many of its users didn't have,
and probably wouldn't have, 64 hardware when they had to make a
decision about which way to go. They also realize like many other
software vendors, that you can't just break the whole user base that
you have built. Even Microsoft had to make the same decision when
they decided to release Vista. And, just in case you don't know,
and I would bet you don't, even Sun Microsystems did not have 64 bit
Java when We was released. It has only been abailble for a couple
of months. And, for your assertion that 64 bit software runs so
much faster than 32 bit software, I can tell you that the machine on
which i am writing is a 32 bit machine and my brother-in-law has one
almost exactly like this one but with the 64 bit OS and 4 verses 2
GB, and I can tel you that you can't tell the difference for most
applications. Most applications that you run are probably not
compute bound. I worked in the computer business for over 32 years
and I would bet you again that you have no idea of what a compute
bound program is and I can further tell you without knowing anything
else about your blow away system that there is nothing on it or even
my system that is a compute bound application. So, I would
suggest that you change that flapping tire and if you don't
understand me, I'l be more clear, button your lip unless you know
what you are talking about.

Whoops, got a cheer-leader mad, sorry.
Nope, not a programmer, never said I was, what I meant to say was
that porting from xp to 32 bit vista was easier than porting to 64
bit so that's why gwmicro decided to do the easy code instead of
tackling 64 bit, you know the immediate gratification thing.
But the easy path isn't always the best one because 64 bit is gonna
be a much bigger player than 32 bit vista or windows 7 and we're
seeing that now.
I just looked at what I wrote, and I can maybe see why you might
have gotten that confused,
but taking things in context and what I wrote afterwords, it seems
pretty clear to me what I was saying.
Maybe that's a limitation of the programming mind 'grin'.
But no offense intended, all the cheer-leaders can sit down, and if
it weren't for people like me pushing the envelope, and expecting
the highest for our hard-earned money, these guys would get fat and
lazy and really get behind.
I have to keep up to be competitive in my field of expertise, so I
expect the best tools for the job.
As long as I've got money invested in gwmicro, I have a right to
expect the best, just as my clients I do work for have the right to
expect the best from me and believe me, they do, they keep me on my toes.
So, my email was a compliment to the company in fact,
maybe not a cheer-leader style, because the way it goes on these
lists is that you tote the party line and don't say anything bad
and then appologize when you do ask for something or mention
something that needs to be done, or that should have been done.
I won't do that, I tell it like it is.
I'll do it respectfully, and some times I might pull a chain or be
a little cheeky, but that's just how I am, people that don't like
my posts can hit the delete key 'grin'.
I know this is hard work but if your going to be the best and say
your the best, then deliver the best.
It doesn't matter now, we've got 64 bit.
I just think in retrospect that gwmicro would have served
themselves better if 64 bit had been a priority earlier rather than
32 bit vista.
But yes, I do indeed understand that that would have been the
harder thing to do.
Regards.

Chris, what programming expertise do you have to warrant such a statement?

Actually, our guys came through and weren't lagging too far
behind the competition on this one, makes me proud.
We indeed have 64 bit.
I mentioned to the fine folks about some time ago, or some such
when vista 32 had just come out and that was probably the easy code to do.
I said 64 bit was gonna be the big thing, and they were starting
to become more and more on systems even then.
I got spanked for mentioning such a thing 'grin',
because gw were patting themselves on the back for vista 32 release,
but serious attention could and should have been implemented then
because some of us could see which way the pig was running.
And sure enough, 64 bit is taking over now and how nice if we'd
been first because vista 32 isn't that big a deal and I believe
in my heart that 64 bit flavor of vista, and most likely 64 bit
windows 7 will be the winner like xp is.
Vista 32 was a big flop in the industry and everybody knows it.
Hmmm, let's see 4 gig architectural limit, but more over-head for
the os equals less memory for the programs, equals doggy performance.
So atleast now because I don't have a 64 bit version of jaws, if
I want to slap 64 bit sonar on this fine dual core machine and
not cripple it with a 32 bit os, and really get in to high gear,
even with no scripts and such, I might have some chance at access
because all the versions of sonar since version 5 will do 64 bit.
So thanks guys for not making me wait too long 'grin'.

Hi,
Does WE support 64 bit OS yet? I'm asking because I placed a order on
Monday for a new desktop system from Dell and I just found out that it's a
64 bit system. I really hope it is one because I haven't been around in a
while.
