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…

I have a VS2010 project that was tested with CUDA 4.0, today I installed CUDA 4.2 and I want to update this project, the problem is that when I try to run the project it asks me for cudart32_40_17.dll, but since this is CUDA 4.2 I only have on my folders (C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v4…

I use ubuntu 12.04 64 bits with GTX560Ti.
I install CUDA by following instruction:

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…

I have got the cuda driver, toolkit and sdk installed in Ubuntu 10.04. I'm using nVidia Geforce 8600 GT card. Official website says my card is CUDA supported. But on running the deviceQuery that comes with the cuda sdk, I'm getting the following output.
./deviceQuery Starting...

I am myself surprised that I am writing this post today. I am going to present one of the very known facts of SQL Server SMALLDATETIME datatype. Even though this is a very well-known datatype, many a time, I have seen developers getting confused with precision of the SMALLDATETIME datatype.
The precision…

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…

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…

According to the entry for decimal and numeric data types in SQL Server 2008 Books Online, precision is:
p (precision)
The maximum total number of decimal digits that can be stored, both to the left and to the right of the decimal point. The precision must be a value from 1 through the maximum…

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…
