CUDA Driver API vs. CUDA runtime

as seen on Stack Overflow - Search for 'Stack Overflow'
When writing CUDA applications, you can either work at the driver level or at the runtime level as illustrated on this image (The libraries are CUFFT and CUBLAS for advanced math): I assume the tradeoff between the two are increased performance for the low-evel API but at the cost of increased… >>> More

I'm currently using CUDA.NET library by GASS. I need to initialize cuda arrays (actually cublas vectors, but it doesn't matters) in one CPU thread and use them in other CPU thread. But CUDA context which holding all initialized arrays and loaded functions, can be attached to only one CPU thread. There… >>> More

Using Taylor Series to Avoid Loss of Precision

as seen on Stack Overflow - Search for 'Stack Overflow'
I'm trying to use Taylor series to develop a numerically sound algorithm for solving a function. I've been at it for quite a while, but haven't had any luck yet. I'm not sure what I'm doing wrong. The function is f(x)=1 + x - sin(x)/ln(1+x) x~0 Also: why does loss of precision even occur in… >>> More

I have a TDateTime variable which is assigned a value at runtime of 40510.416667. When I extract the time to a TTime type variable using the Frac function, it sets it to 0.41666666666. Why has it changed the precision of the value and is there a workround to retain the precision from the original… >>> More

Why don't computers store decimal numbers as a second whole number?

as seen on Programmers - Search for 'Programmers'
Computers have trouble storing fractional numbers where the denominator is something other than a solution to 2^x. This is because the first digit after the decimal is worth 1/2, the second 1/4 (or 1/(2^1) and 1/(2^2)) etc. Why deal with all sorts of rounding errors when the computer could have… >>> More
