FP-intensive Distributed Computing?

[imgod2u]

I know Prime95 stresses the integer operations of a CPU a lot. However, I'm looking for a FP-intensive stress-test to run in parallel to prime95 to really test stability. Is there any such thing? Is folding@home FP-intensive?

ECCp is floating point intensive (i.e. Athlons rule while pentium 4 cpus perform badly).

Actually, all the ECCp code I worked on was in integers.

As a matter of fact, I think Prime95 tends more toward the FPU. I know Proth ran very slow on my old Cyrix (RIP) which did badly mainly on FP operations. RC5 is a good integer test, though ECCP uses a greater variety of instructions.

As said above, prime95 is pretty much all FPU when it comes to using your processor.

It gives quite a workout to your memory also, since all the FPU calculations are constantly writing and reading results to memory. Prime95 is also very sensitive to any hardware failures, be it CPU or memory..........it errors out when most other programs would run fine. I think it's an excellent CPU test. 😀

Ken,

Opps. I assumed that ECCp was fpu intensive mainly because P4's perform so badly. I thought that the P4's integer calculations were relatively fast when compared to the Athlons...
