@Bob Where I live, Apple 5S is more expensive than Nokia 1020.

Bob

@Boris_yo and? isn't that what I just said?

Boris_yo

@Bob My mistake. I meant Apple here is... Where is that article... I forgot. Bottom line is that person saying it told that Apple and Samsung will come cheaper and you will be left with change in your pockets.

Bob

...quite the opposite

both Apple and Samsung flagships are more expensive than the 1020

Hm, the S4 might be cheaper in some places. But it's close (within $50).

Boris_yo

@Bob Here Samsung Galaxy 4S (16GB) is $200 cheaper than iPhone 5S (16GB) while Lumia 1020 (32GB) is on par with iPhone price.

Lumia 920 is like 2x cheaper than Samsung Galaxy S4.

How much bytes are accessed in one burst from ram ?

Mr. White

14:34

Hi!!

Everyone

Just asked a question over in SU Mod;

Would SU be the correct forum to ask - Is an unused, or written optical disc more reflective?

Mr. White

Anyone knows what is the rule that drops reset packets to specific port?

iptables?

Braiam

@Everyone remember we are not a discussion forum but Q&A

Everyone

@Braiam Yep. It's a straight yes/no question though I'm not sure whether the question as it stands is a fit

Braiam

ha! this is ridiculous, the antispam ip-based system that I have in my forum is blocking myself from posting...

Journeyman Geek

14:39

@Everyone: unused.

Ash

@Braiam lol :) did it just became self aware ?

Journeyman Geek

what's the practical point of asking that tho? ;p

Everyone

@JourneymanGeek That's what I thought too. Constructing a solar collector (+: I'd guess the difference between a well-preserved used/unused disc would be relevant

Braiam

@Ash nah, is my stupid country that has dynamic ip and the databases are from 2009-2011...

Everyone

@JourneymanGeek Didn't I see you over in The Pod Bay the other day?

Journeyman Geek

14:42

pod bay?

Ash

sounds like med bay in elysium

Journeyman Geek

I don't think so.

Everyone

No worries

heh. The Pod Bay is the chat room for SEx.SE

Journeyman Geek

Bob

@Everyone maybe Home Improvement?

o.o

That's its name?

Everyone

@Bob For the optical disc question?

Bob

(I always knew it as diy)

Journeyman Geek

lol

I'd rather have it asked and answered in chat

its one of those things that dosen't fit too well anywhere ;p

Bob

14:48

true

but if the goal is to build a solar collector...

Everyone

I think I've just been insulted q+:

Journeyman Geek

>_>

@Everyone: hope it wasn't me

Everyone

No no no. The target is to construct a collector; the goal is to try to cook food (+:

Bob

yea, sounds like material for diy.se

Everyone

haha @Journ no worries

Journeyman Geek

14:50

lol

the specific question though... ;p

Bob

but not the optical disc question as it is :P

Journeyman Geek

We're talking about computer hardware, in a non computer setting.

Everyone

lol

Is an optical disc even computer hard-ware? (+:

Journeyman Geek

lol

I consider it as such

Braiam

err... I think it fits in "peripheral"?

Ash

14:51

what about "physics" ?

Braiam

"data storage"?

Bob

I just found a 64MB stick of RAM \o/

@Braiam more like media

as in storage medium

Everyone

@Braiam Something like that (+: it's not really a good fit anywhere I know. But SU seemed a better option than SO, or some of the other stacks

Bob

@Ash depends how you phrase it

Journeyman Geek

@Everyone: least on SU, we use chat for those outliers

Bob

14:53

@Everyone wants to build a solar collector

Braiam

well, CD first worked in players (as music) then someone got the great idea to store data... no?

Journeyman Geek

I can tell you I know this from the time I had to burn 200 cds at once...

and forgot which stack was which

Bob

Asking on Physics.se would be more for the theoretical reason

which is immaterial here

again: ask according to your goal, don't make it an XY question

Everyone

@JourneymanGeek We're trying to do that over on SEx too; use chat to filter a bit. Hardtly have the amount of traffic there that you have here

Journeyman Geek

lol

we have a few chatty regulars, mainly

Bob

14:54

@JourneymanGeek would depend on the specific dyes used

Braiam

wait, wasn't SEx dropped?

Bob

and more/less reflective would be hard to determine for the IR spectrum, too...

Everyone

Eh? No!

Ash

why not use mirrors instead ?

Everyone

@Bob That would be a factor, but given a set of CD-R/DVD-R from the pack ...

Bob

14:55

@Ash do you know how hard it is to get mirrors for specific sizes without spending a small fortune?

Everyone

@Ash (+; I have like a few quintillion coasters

Bob

@Everyone and then CDs and DVDs would be different, too

too many factors

just flip a coin and pick one :P

they're all close enough anyway

and again factory pressed discs would be different from dye-based burnable

and the dye fades under UV anyway

argh

package arrived in Sydney 10am friday

Everyone

@bob that's what i'll hae to do. The weirdest thing is the refraction off the edges at 180. Red tinged light

Bob

have to wait till Mon or maybe Wed for delivery -_-

so annoyed

Journeyman Geek

@Everyone: in this case I'd just use burnt ones

they do scatter the light a little more, but its just more practical

Everyone

14:58

@Bob The trouble will be getting them all to focus over a particular area; I need a frame of sorts ...

Braiam

there are 2 files because one is from all users and other is from your user profile

Braiam

@Boris_yo one for "all users/public" and another for your user

Boris_yo

@Braiam How can 2 files exist with similar names?

Braiam

they are not in the same directory...

one is in the c:\users\public\desktop and the other is in the %homeuser%\desktop

I only have a /dev/lava when my CPU is under full load.

133 Watt of room heating. ;-)

Maybe I should fire a cooling LASER at it.

Boris_yo

@Hennes Can laser cooling be possible for CPU?

Hennes

No.

The first paragraph (on wikipedia) is actually quite easy to understand.

Usually it goes overmy head when I dive into deep physics, but this one is clear.

Doug_Ivison

18:47

Welllllll.... talk about a LONG shot... anybody out there been a user of the MEGA (Molecular Evolutionary Genetics Analysis) software? It's running very slowly, and we're trying running MULTIPLE INSTANCES of it, to save time... but we wish we knew whether it's ok to do that.

Question already posted on Stack Exchange's stats site: stats.stackexchange.com/questions/78966/…

Hennes

Generally, laser cooling has been only used on the atomic level to cool down elements. This may soon change, as a new breakthrough in the technology has successfully cooled a macro-scale object to near absolute zero.[2] In 2011, a team from the California Institute of Technology and the University of Vienna became the first to use a laser to cool a miniature mechanical object to its quantum ground state.

@Doug_Ivison Is the software multi-treaded?

If it is not then running one instance per (real) core might improve or even double performance. If it is MT, then you are likely slowing things down.

Doug_Ivison

We didn't develop it, and don't have access to the source. And thank you: that's a good question for us to pose to the professors / developers, who originated it... (though we may not get a response until tomorrow, and don't want to lose a processing day).

Thx.

Hennes

You can test it. Start one instance on a dual (or more) core host.
Go to the task-manager (windows) , start `top` (unix), or whatever your favourite tools is.

If it already uses multiple cores then starting a second instance is not likely to speed it up.

If you see one core at max and the rest at idle then starting a second instance might double speed. (assuming you do not run into new limits, such as filling all the memory, maxing out the disk, etc etc)

Or, in non-computer terms:
See it as reading and translating a book.
You have one person (say a secretary, or a CPU core) doing that.
If you read use multiple book (program instance) and multiple secretaries (cores) then things will be faster.
However you add more simultanious translationsthen there are secretaries (cores) then the secretary will have to switch a lot between books. Putting book A way. Reading a page from book B, translate it. Put book B away, get book A, translate from book A, put book A away, ... Much less efficient.

Doug_Ivison

Yes: with 2 concurrent runs, so far, the run times are comparable (maybe a bit slower for a single instance), and the CPU usage has not changed (still about 12%), and we can see in Task Manager that the CPU % spike is alternating it's "jump up", between the two processes.

Our big question (probably for someone who knows the app) is whether concurrent runs on the same machine pose any problem for the data / results.

Understood -- thanks. We're ok if both processes running separately took 30 mins apiece, and together do not finish for 45 mins, because the total run time would have decreased from 60 mins.

Hennes

I only see a few solutions:
1) Get access to a faster machine. (which may not be possible)
2) Run on a few machines (one instance each)>
3) Start earlier. (which is nice for future things, but useless for you right now)
4) Reduce the dataset

As for 4). This kind of problem sounds like something which uses a lot of memory, which means it might be memory bound. So use an appropriate CPU (Ancient opterons will do, or modern core iX intels. Not a core2 or earlier Intel)

Doug_Ivison

18:59

Actually doing all but 1, already. (The totally loaded workstation that we started on was probably the fastest -- running faster than the 2 servers we are now also running it on.)

Hennes

There might be other users on those servers.

Using part of its power.

Do you have access to multiple workstations?

Doug_Ivison

We wanted to process 30 sets, but at this point, will be lucky if 5 are done.

They're development servers I manage, and nobody else is on them. (This is all helping my daughter with her project :) ...she's got the problem, and I've got servers nobody's using this weekend.)

The other two grad student in this project have (1) a mac -- won't run it, and (2) a way old windows laptop, that doesn't have the disc space for it.

Hennes

If you had enough time (doubtful) I would start by analysing why things are slow? To much data, need a lot of CPU calculations? Needs lots of work space (RAM), etc etc. Then select the best computers for the task.

But at deadline minus a day that is a tad late for that.

Doug_Ivison

Thanks much for this dialog.

Agreed.

Based on my daughter's explanation today, the nature of this kind of DNA statistical analysis is that you start out with the most pertinent sequence (like for traits you're trying to find the evolution of), and compare strands of possibly-related organisms/samples, and use the statistics to come up with a probability of relationship.

Then, if you're not close enough to 100%, you add more data (more strands from organism A and organism B), and, as long as the probability of relationship is continuing to go up, you keep adding data until you get to 100%.

So, you don't always know how much data will be required.

Doug_Ivison

19:21

The deadline is Thursday, but she estimates it would have taken 33 days to process all the data, on her workstation alone... so now we're targeting 1/6th the data, on these multiple machines.

allquixotic

19:40

all that sounds super interesting, but I'm on the clock (on Sunday :() and have to get this coding done ... damn I'd love to sink my teeth into that, sounds very interesting, performance, big data, and DNA all at once :D

Hennes

True. However I find the ask to ask more polite.

allquixotic

20:12

@Hennes in technical communities, politeness is often less important than not wasting others' time

2

not to say that we intentionally try to be impolite (except for people like Linus Torvalds who can get away with it while maintaining his position), but when politeness really just makes things take longer, and serves no other purpose, it's of secondary concern

there's a difference between being impolite and offensive, though... it's very possible to drop the politeness while still not being offensive, by just focusing on the technical issue at hand and ignoring all interpersonal issues (don't even mention them, or process them when other people mix them in)
