CUDA

Spent Sunday attempting to get CUDA - somehow didnt install
- one page reckoned that CUDA gave only a 2x speedup below 4kbits
Then I tried to get GMP, despite it having no claim to use CUDA
- got tangled in the usual Linux gcc Crapola ... Linux prissy purists insist on handing you the "source" which you have to compile with gcc
but windows gcc is itself fraught with crapola and pils of anxious (outdated?) complaints about it all
..


So the free arena is Crapola, I need to buy mathematica? ...MatLab has nifty pages on CUDA .. but you have to register to see the price !? (Thousands"??

a Quote:

. I do not think SciLab and Octave are viable alternatives to MATLAB for me. I think Python is a viable alternative for me. There is not much that I can do in MATLAB that I cannot do in Python. There is no question that if I was just starting out I would use Python instead of MATLAB. MATLAB, however, is cheap for me compared to the cost of porting my existing code to Python.

Maybe the best way to get bigint/cuda might be to sign up with one of the global shared computation efforts, one assumes that they will download simply...



Meanwhile: notes on OpenCL (I cant determine if OponCL is a rival of CUDA, or an older obselescant device)

It just so happens that Radeon cards are quick with integer calculations so they were the perfect tool for the job increasing the hash rate by magnitudes of 100+. M
Radeon 5770 is not the fastest card around but packs way more punch than a traditional CPU. It also looks like Radeon cards are faster than their Nvidia counterparts especially when it comes to password brute forcing and the latest Radeon 6990 graphic card should be several times faster than my Radeon 5770 and should make ANY 8 character password obsolete.

he University of Georgia was experimenting with this last year.

They were able to gang GPU’s to achieve staggering results, even 12 character passwords are crackable in a sort amount of time.

Radeon HD 5970 can execute 3200 32-bit instructions per clock (using its 3200 ALUs or shaders


$350 for the HD5970
AMD Radeon HD 6990: 3072 ALUs x 830 MHz = 2550 billion 32-bit instruction per second

...if you’re the pioneering (sic) type who likes to swap smartphone batteries in the field: The battery that comes with the stock Galaxy Nexus includes an NFC antenna inside of it (..like Android Beam, for instance). ..So unless you’re swapping that battery cell out for similar one, don’t expect to be waving your Google Wallet around anytime soon.

Google ... integrate Google Wallet into mobile web payments.
.....probably would not make sense yet..... with Fandango.com and MovieTickets.com to offer Google Wallet as a payment option for their mobile web checkout.
...users won't have to try to type their 16-digit credit card number plus the expiration date and security code on their phone.. Typing on mobile phones is a notorious hassle, and mobile Web users often abandon their online shopping carts when they reach the point of entering payment information.

[OK EMV NFC, we have the technology... we can read the CCNumber,ExpDate (but not the 3digit
...Card Security Code (CSC) ... Card Verification Value (CVV) or Card Verfication Code (CVC)]

.. also offer their own apps for iPhone, Android, ...
It's unclear whether Google Wallet will be offered as a payment option for in-app purchases -- but ..."if Google decided to offer this ability, it might "pull the rug out from underneath Apple's 30% tax on in-app purchases."

Auckland Transport's announcement calls the new card an "integrated smartcard," which is, as I've observed before, rather gilding the lily. The service is hardly all that smart, nor very integrated. It's just an electronic cash substitute that can deduct a fare from your card.
...A fully integrated system would include a zonal charging system where passengers were levied for the distance travelled regardless of changes of transport mode on the way.
Even when the new "integrated card" comes in, swapping from bus to train, for example, will incur a new fare.
In a letter to transport committee chairman Mike Lee in August, Mark Lambert, Auckland Transport's manager, public transport operations, outlined how the organisation planned to implement the "integrated public transport network" model over the next three or four years. He painted a four-tiered network of routes, the backbone being a rapid transit network of electrified rail and dedicated busways, interlinked with a secondary grid of bus services.
But absent in this three to four-year plan is any mention of a simplified fare system. One that doesn't punish the commuter for changing modes mid-journey. The new $87 million "integrated ticketing system" is capable [sic] of doing these calculations. When will it be asked to is the question.
