What’s the Big Deal with CUDA and GPGPU anyway? | VizWorld.com

GPU’s are designed for pushing pixels, not crunching numbers. The fact that they can crunch numbers is almost an accidental side-product of their main purpose, discovered several years ago and only recently becoming something worth investigating.
problems

- slowest part of the system is loading your data to the GPU, and reading it back from the GPU.
- No support for Branching Operations or Conditionals
- language itself is incomprehensible
- NVidia saw this problem, and has been working for the last several years on alternatives like Cg, CUDA, and most recently OpenCL. These libraries, combined with changes to NVidia’s hardware, make writing GPU programs not much different from writing traditional programs
- first two points are still a problem, tho. Transferring data from the GPU back to Main Memory is the biggest hindrance to GPU programs
- your algorithms need to be structured in such a way that all of your data can be thrown into the GPU, let it swirl around as long as possible, then read back an answer. Algorithms that compute a number and then use that in another computation, in a Recursive fashion, simply don’t work well in a GPU
- huge refactoring of classic algorithms into new parallel-friendly means. One fun example of how many people have been working on this is a quick search for “parallel FFT” (Fast Fourier Transform, the foundation of many audio and image processing routines) that turns up 140,000 papers in Google Scholars.
- Intel has put a huge gamble that their new Larrabee chip can give them a door into the upcoming GPU-accelerated computing revolution. NVidia and ATI (now AMD) have had a long-fought duel over who will win, and only now are we beginning to see a serious third player in Intel arrive.
- OpenCL is also emerging as a standard library to provide cross-platform support for GPGPU algorithms. Currently most solutions are restricted to only a single GPU-vendor, but OpenCL promises to do for GPU-computing what OpenGL did for GPU-rendering. By providing a standard API that can be implemented and supported by multiple vendors, costs should fall for the consumer and opportunities rise for developers.

Whither the efficient-markets hypothesis?

The efficient-markets hypothesis has underpinned many of the financial industryâs models for years. After the crash, what remains of it?

Key Themes in Financial Services 2009-10
Mega-trends such as transparency, centralized exchanges, increasing specialization and disaggregation of services will rule the day,

- high-performers will be paid. But cash compensation will be capped at a fraction of the amounts previously paid out, and the stock that is awarded will have long-dated vesting and be subject to clawback for losses attributable to personal performance. I believe we'll see a $1 million cash compensation cap, 5 year cliff stock vesting and a clawback on unvested shares.
- Once dominated by the sell-side, the majority of research consumed by the buy side will be sourced from third-party providers
- leverage lightweight, flexible technologies for publishing and disseminating their research.
- expert networks" will continue to proliferate, seeking to connect those with domain experience with those in need of deep, targeted insights. Gerson Lehrman Group (GLG), the 800-pound gorilla in the field, will continue to flourish
- key to accessing research in a fragmented landscape is the discovery layer, the matching of interests with knowledge. This will continue to be a "hot button" topic as investors work to become more efficient and streamline their investment process
- Derivative contracts will migrate towards exchanges, forcing standardization across much of the derivatives industry. Interest rate swaps and options, credit derivatives, the whole lot, and not just for standardization and transparency, but for collateral management.
- largest element of the "bailout black hole" relates to counterparty risk, e.g., were AIG to have gone bankrupt, it could have dragged many of its counterparties down with it. However, had it been forced to post collateral pursuant to a centralized clearinghouse function, it couldn't have delayed its day of reckoning to a time when the problem was so large it didn't have the necessary liquidity.
- take away significant profitability from the banking sector, it could make up some of the losses through higher trading volumes due to liquifying and deepening previously opaque markets.
- Hedge Funds
  
  More regulation will come,
- Focus on risks and reporting. For hedge funds that aren't publicly traded, and whose investors are accredited, the main purpose of disclosure is for regulators to understand the concentration of risks across the financial markets, and to avoid the "too big to fail" problems we've had repeatedly ever since LTCM bit the dust in 1998.

Madoff Misled SEC in '06, Got Off - WSJ.com

finance trading stocks

Mr. Madoff personally "misled the examination staff about the nature of the strategy" used by the Fairfield funds and other hedge-fund accounts, and also "withheld from the examination staff information about certain of these customers' accounts,"
Whether the markets were up, or down, Mr. Madoff managed to clock in with steady gains of 12% or so a year, reportedly achieving that by trading a mix of stocks and stock-index options.

- Mr. Markopolos and a colleague at their Boston investment outfit tried to reconstruct Mr. Madoff's purported strategy. Their results paled in comparison, and Mr. Markopolos began suspecting possible fraud.
- turned to Daniel DiBartolomeo, a top financial mathematician in Boston. Mr. DiBartolomeo says he spent hours poring through Mr. Markopolos's data, and ultimately agreed: The strategy Mr. Madoff said he used couldn't have achieved the returns he boasted of.
- A key part of Mr. Madoff's strategy relied on buying and selling options on the Standard & Poor's 100-stock index. But Mr. Markopolos said his research showed there weren't enough S&P-100 options in existence at the time to support Mr. Madoff's stated strategy, given all the money he seemed to be managing. So something else must be going on.
- He also questioned the fact that Mr. Madoff, unlike most money managers of his stripe, didn't charge his investors a fee for handling their money. Instead, he seemed to make profits on commissions generated by the trades on investors' behalf.
- Investigators also checked out Mr. Markopolos's claim that Mr. Madoff was running a Ponzi scheme. But the billions of dollars of assets held by Mr. Madoff's asset-management unit appeared to match those that various investment firms said they had placed with Madoff, suggesting that there weren't problems.
  
  Today, it is now known that that Mr. Madoff had many more investors -- such as individuals and charities -- which weren't disclosed in regulatory filings, making it harder for investigators at that time to ascertain precisely how much money he was managing.

The Great Derivatives Smackdown

Ari Weinberg, 05.09.03,
Buffett fears that there is a lynchpin out there in the derivatives market that, when pulled, will send the financial world into a spin. Essentially, the Oracle of Omaha wants nothing to do with this hot-air market.
