...The integral is computed within a C-function called Denom by use of function qags from the gsl library. Here is a piece of R-code: denom<-try(.C("Denom",as.double(x),as.integer(n), as.integer(p), as.double(param), as.double(delta),res=as.double(results))) denomres=if (class(denom)=="try-error") NA else denom$res Sometimes, it happens that the integration process fails with the follwoing error message gsl: qags.c:553: ERROR: bad integrand behavior found in the integration interval Default GSL error handler invoked. and the whole simulation...

...bject file adds a static constructor that sets the DAZ and FTZ bits of the MXCSR register. I expect that it has analogous behavior for other architectures when it is available. This object file is typically available on Linux systems, possibly also with things like MinGW. If it isn't found, the denomral control flags will be left in their default state. There is also a CUDA-specific option, -f[no-]cuda-flush-denormals-to-zero. I don't know how this is implemented, but the documentation says it is specific to CUDA device mode. Finally, there is an OpenCL-specific option, -cl-denorms-are-zer...
