Convolutions Again

I’ve gotten my PyOpenCL convolution implementation updated. In my previous results, the overhead of PyOpenCL kept the GPU based implementation from being better than the CPU based implementation until the input array sizes grew larger than 200. Now I’ve gone in and implemented batched runs, allowing for multiple convolutions to be run in parallel on the same input.

And it works pretty well:

This figure is not directly comparable to my original PyOpenCL figure, because this is for 3d convolutions and the old one was for 2d, and there were fewer runs (10) and fewer convolutions per run (500) in this figure. However, the GPU implementation is incredibly fast now. There’s only one snag… the x axis stops at 100 because my runs at 120 were freezing up my display driver. I think it’s a memory issue, and hopefully I’ll be able to fix it up without too much trouble, but being able to quickly do (relatively) small convolutions is enough for me for now.

The shading is the standard deviation, and there’s a lot more variance in the GPU run than in my previous results. I’m guessing that’s because I’m actually using more than 10% of my GPU, so it can run into other processes using the GPU now.

Inflation is a tax.

This is required reading for every poster who claims that "taxes" on the poor will not be levied.

I love the Keynes quote at the beginning of this piece. I really do. I mean, here’s the architect of so-called quantitative easing basically saying, “By making you think your house is going to be worth more every year, your government is stealing your money. And you don’t even know it!”
Again, this isn’t Murray Rothbard, or Jim Rogers, or Peter Schiff, or Milton Friedman! This is John Maynard Keynes telling you your government is stealing from you!

Politicians are a problem; but I think we

Are failing to view current events in their historical perspective. For example, compare today's politics to the Boss Tweed days. Or compare today's corporate power to the time of the robber barrons. People like the Rockefellers, Roosevelts, Bush's, Mellons, Ford's, and Carnegies have always ran things. Now, however, they must do so behind the scenes. I guess that's some progress. So I would posit that we live in a more democratic country than at any other point in our history.
There has alway's been a tug-a-war between Wilsonian globalists & isolationists like the Republicans under Hoover. IMHO there is probably a happy middle ground we haven't found yet, but to say that we're toast because of NAFTA is I think an overly harsh analysis.

God is the new global currency

2008-01-08 17:56:40 by -

There was a time when gold was money. In today’s uncertain world, the yellow metal is back in fashion. Bullion prices rose to a record nominal high after the assassination of Benazir Bhutto in Pakistan added to nervousness about the world economy. Part of gold’s allure is its traditional status as a safe haven. It is seen as a store of value when everything else seems risky. But the bigger drivers behind the rising spot price are a depreciating dollar and the prospect of negative US real interest rates. A better way to think of gold may be as central bankers used to before America dropped the gold standard: not as a commodity, but as another currency. As long as the dollar stays weak, gold’s bull run will last.
The arguments for further gains in the gold price are compelling.
