Pi
Seems that By Alexander J. Yee numberworld isnt using any NVIDIA processors, just Intel CPUs to calculate 10Trillion digits of Pi.

Hes using Intel 'Xeon 5680' which is a 6 core superior to the i7 (at $1600 it oughta be)
He says he hasnt done any work on CUDA
but "v0.5.5 is faster on processors with AVX instructions."

Meanwhile, If you merely want to run other-region DVDs, get VideoLAN software
Its grand that LapTops have HDMI sockets.
Who needs a TV set?     (except: "that 70's show" isnt on Demand...)
Not So grand that I dont have a "Home Theatre"

Of Course if you live in Sydney you can get "multi-region' DVD players... they arent allowed to advertise as such, but downtown Sydney had charming "Barkers" outside stores shouting "get your unlocked DVD playes here" (is this still true?)
great for those 20-title DVDs you picked up in PatPong

Intel i5 chip seems adequate, get an i7 if you like.

If you want heavy games, better get a tower with slots for NVIDIA cards.
Never been into games much, myself, same as Steve Jobs.

Since 2007 NVIDIAs CUDA has brought super-computing to anyone with a game card...

"GeForce GT 220 packs 48 processing cores into a compact power efficient.."(< $80)   2009

 this year: NVIDIA® GeForce® GTX 550 Ti graphics processing unit (GPU) $150 "GPU called GF116,"
... Ti is a Fermi?? newegg

:The refreshed Fermi chip is large: it includes 512 stream processors, grouped in 16 stream multiprocessors clusters (each with 32 CUDA cores)," ??

The GF116 has a single Graphics Processing Cluster (GPC), with four Streaming Multiprocessors (SMs). Each SM contains 48 shader cores, four dispatch units, and eight texture units. All told, GF116 employs 192 shader cores, four Polymorph engines (one per SM), and 32 texture units.??

... and all three ROP partitions are fully functional.. similar to the uncut GF106 GPU in Nvidia's GeForce GTX 460M mobile graphics module. With each of the three ROP partitions capable of eight 32-bit integer pixels per clock, we have 24 ROPs and a cumulative 192-bit memory interface..
(24 * 32bits per clock doesnt sound all that grand .. maybe a "shader unit" can do a multiply?)


..............................................
ATI (AMD) Radeon HD 5770 features the exact core configuration of the Radeon HD 4870 and 4890: 800 SPUs, 40 TAUs (Texture Address Units) and 16 ROPs (Rasterization Operator Units).
might be better than NVIDIA, but as NVIDIA write CUDA , they might be more copasetic
"The Radeon HD 5770 features a remarkably low 18 watt idle consumption level, making it one of the most efficient graphics cards available today. When pushing the card to the extreme it will still suck up to 108 watts, but even with the increased thermal stress, noise levels were comparable to those of the Radeon HD 4770 or GeForce GTS 250 graphics cards."
...........................................
Jargon ROP Raster Operations Partition? ROP partition = ROPs + memory controllers + L2 cache .
...........................................
GeForce GTX 295 Each GPU features the full array of 240 processing cores and 80 texture filtering units. The processor cores and filtering units operate at 1242 MHz and 576 MHz respectively ($500? fits in one slot?)
There are GPU cards up to $700.




Either pay $$ for Mathematica 8 ..'Native support for Compute Unified Device Architecture (CUDA) and OpenCL GPU'
or write yr own.

Me, I'd like to set a couple of cards making Carmicheal numbers and seeing how many Miller-Rabin bases I can fox.
At 2048 bits, any more than 2 bases would be fun!



I'm assuming that GeForce work well on Integers. Surely better than AMD 8-core Bulldozers ($205-4245)
cnet


Since I dont do games, or huge monitors, most of the fun would be lost if I bought a DEsktop and a couple of GPU cards

jcuda

JCublas is a library that makes it it possible to use CUBLAS, the NVIDIA CUDA implementation of the Basic Linear Algebra Subprograms, in Java applications.

JCublas provides methods for
Vector operations (Level 1 BLAS)
Matrix-Vector operations (Level 2 BLAS)
Matrix-Matrix operations (Level 3 BLAS)

- so no Integers??
I suppose that means dusting off JNI

Thales never sleeps

16 August 2011 Thales, ... announces the world’s first software for Hardware Security Modules (HSMs) that enables mobile payment issuers to deliver their mobile payment applications to mobile handsets Over-The-Air (OTA) in a simple, efficient and secure manner.
..
Today’s mobile payments issuers have to use multiple core cryptographic function calls to build the data needed to issue a payment application and to create the secure messages required to personalize the mobile phone with the application Over-The-Air (OTA)..
Thales HSMs now provide for the first time the ability to create a secure message to personalize a payment application hosted in a GlobalPlatform Secure Element, resident in a mobile phone using a single dedicated cryptographic HSM call...

.. Intel Advanced Vector Extensions Programming Reference (June 2011)... AVX2 (256-bit integer AVX instructions) and some VEX-encoded general-purpose instruction for bit manipulation et al.

'm assuming by an 8 core Bulldozer, they are actually really referring to a physical 4 core CPU that has 8 integer cores and 4 FPU cores. I think this terminology will trick a lot of people, because in reality, it is really only a quad processor that happens to have 2 integer units per core :). The extra cost of the extra integer unit per core was apparently very minimal, so cost wise the Bulldozer should be comparable to the Sandy-Bridge, just (supposedly) a lot faster! In addition to both having AVX instructions, the Bulldozer has the additional benefit of having what was once known as SSE5, but is now FMA4, CVT16 etc, although I'm not sure whether they will be beneficial for encoding.

with tag C1 and CLA 80  C10200C5  which looks better    sequence counter (?) is C5 ???
This is said to be used to derive session keys??
In practice we use the 108100..00 derivation data, so when is this sequence counter used??
It is said that only SCP02 responds to C1,so there's a test for you...

Note the GetData CLA can be 00 or 80   80 is better.....
there is an undocumented CLA of FF which returns 2DB3BB28 irrespective of p2 .....
