I would like to download 4-5-6 piece endgame tablebase. This exercise could take about 1.2 terabytes and close to 1 year. My suburb does not have ADSL2+.

What is the fastest way possible I can do this? What way would you do it?

might be easier to just move to a place with ADSL2+

Call Internode and ask if they can develop a custom business system for you. I'm sure they could come up with a plan and price in the range of about $1.2bil/mth.

I have no idea what you want to download but given the size surely it would be easier to contact the people that have the data and ask them to send it to you on some physical media.

Cheapest approach would be to ask a friend to post them from USA. Probably still cheaper to catch a flight to the USA and take two external hard drives.

Alternatively you could hope there is a chess fan at Internode and ask for the files to be added to the mirror server.

Sneaker net.

Send someone a few 1TB hds and get them to do a copy for you?

Is there a way of generating the table base locally? Do you need to download it or can you just download a piece of code to do it?

ROTFL Classic!
I've already sent that link on to lots of others. Thanks :-)

Where exactly is this database & who made it???

I've seen some pretty huge chess databases (20GB+ Bookup database) but that just sounds insane...

A quick Google search shows you can get a generator from here members.chello.at/cm-codeman/TB_Gen.rar

I haven't used this, so I can't say whether this works or not. Is certainly smaller than the 1.2TB you are looking at downloading :-/

make it a WP user project.
everyone downloads 4.4gig of it and posts it on DVD? ;)

Just get a Telstra Business ADSL2+ (max 20mbs download so not true ADSL2+ but close) unlimited plan. It is about $300/month

Quick google search seems to indicate most people use emule to get them.

BTW: It seems to be a chess solution set database for chess nerds (if you were as curious as I was).

OT but one more addition to sneaker net :-)

Fastest? Sneaker net, I'd suggest (as others have).

Most cost effective via the network? Probably one of Internodes' new Business Unlimited plans at 1500, which would allow > 400 Gb per month in downloads (assuming you're able to run efficiently from the source servers concerned 24x7), and hence would let you pull the lot in 3-4 months.

lol get it mirrored :)

If Simon's a chess player he might want it mirrored too!

What's the location? I want to see how many files there are. Then maybe I'll get a bunch of nerdy friends together and who knows...

Is that the correct files? If so, it's only like 7GB of data, and should be easily done on an 8Mbit connection in under a week.

Doesnt he want 4-5-6...

I can see 3-4-5-6.
Nalimov/Kadatch 3-4-5-6.

Size, 1.2TB

is the op sure its 1.2tb they need to download?

Is this what you're looking for - store.convekta.com/shop_...alog&gid=121? Surely it would be cheaper to buy these premade discs here than download the data yourself.

Looks like a location that'll be on Internet2. Know anyone who has fast access at a university (AARNet) network? You'd want to check with the right people first, but it's probably a free download for them (and would be super quick too).

That'd be right, but thats only for 3-4-5. He wants -6 as well. AFAIK, the only place with -6 that is active presently is a huge (!!) set of eMule links. Thats gonna be hard to guarantee the speed on.

To the OP: where were you going to be getting the tables from?

t

The software (C code) to generate the tables is free.

So... For about 1Mb download - generate the suckers yourself.

I'm sure your box is idle most of the time. Setup a batch job to run at low priority. It takes a while (days). Much cheaper than DL.

There's a couple of ancient pieces of C code (tbgen?), but they seem pretty ancient/inefficient :/

As inefficient as DLing 1.2TB? Vs using wasted clock cycles?

With the code I've seen, we're talking several months if not years...

Definitely better to go for the sneakernet...

What would be interesting would be an FPGA or GPU implementation of a table generator... from my limited understanding, both of these would be well suited to such calculations.

Never underestimate the bandwidth of a postpack filled with DVDs... Find someone who already owns it and send them a case of beer.

I'd suggest just posting a couple of 750GB HD's ;)

This was how I did my file sharing with friends in the Gold Coast back before I had ADSL :P

your kidding !???
POST & HDD's , in the same sentence ?!
sure hope you pack them well.

Jay Binks writes...

No?

Electrostatic bag + bubble wrap + those little foam pieces.

Still got the HD's today (Two Seagate 10GB disks)

The way storage is going we may yet have the ultimate 32 pieces EGTB.

:-)

Then we can prove 1. d2-d4 = 1-0
and 1. e2-e4 = 0-1 :-) :-)

LOL, I have no idea what that means, but it sounds funny.

I vote other. These stealth Trolls are getting more creative all the time :).

Use Bittorent.

Filled is the right word, it'd take 270 :|

Pawn to Queen 4 (1st move) wins Pawn to King 4 loses.

Some people prefer a queens pawn game and believe it is superior to the king pawn game.

You seem to have completely misread the opening post.

send them hard drives, or get them to buy some blue-rays, or something either way it would be allot quicker than downloading, Sounds like your rich, you could always buy a dedicated server in one of the data centers in aus (there a few) Download the files via that as they usually have 100mbit connections, then.... buy the hard drive off the hosting company lol. Would be quicker and probably cheaper than paying 300 a month or whatever for a business plan ^-^

I would email the University of Alabama and ask them Direct it to the Computer and Information Services Department. Just ask them how you can get access to this without downloading. The Might offer to stick it on HDDs and post them to you for a nominated fee + profit. DVDs and Blu-ray discs are way too much time and effort needed to split the files and burn them.

Email them and ask.. cant hurt..

are you insane. I am amazed at what some people do in there spare time
