About Altera OpenCL Compilation

Hello everyone, I am just wondering if anyone know the difference between compiling kernels in Linux or Windows (in term of run-time performance and total compilation time). I know i could use ...

I have another question regarding numerical accuracy. I noticed that when operating on the same set of data repeatedly (ie. running a iterative algorithm), the difference between CPU and FPGA's result gets quite big when the problem size and number of iteration is large. When not using -fp-releaxed nor -fpc flag during compilation, the difference gets smaller but is still significant. Is this due to Altera implemented floating point arithmetic differently then Intel? I thought that they both conform to IEEE 754 stardand?
