…on test benchmark ?

Can you beat the simplicity of use of its parallel library?

Take any compiled test you want

and compare your CUDA speed with Intel/AMD multi-core CPUs.

Test - the solution of sparse band system of equations.

1 cpu 2.46s

2 cpu 1.22s

3 cpu 0.83s

4 cpu 0.67s

5 cpu 0.58s

6 cpu 0.50s

Is there any source code available for the benchmark? Otherwise trying to perform a similar test under CUDA might be really difficult…

Also, is there any price for a CUDA implementation that beats the CPU?

Prize of course… where has the edit function gone?

Can this solve linear equations ? like:

constant * variable + constant * variable + constant * variable <= 1000;

If so can you give an example of how the input would look like ?

In general

x = 2y

y = x + 4

Or even

x/y = 2

y - x = 4

Of course, there can be more variables…

However, because they are linear you will never see

x = y^2
