Has anyone used the PGI compilers with the latest version (qd-2.3.14) of DD and QD package from Berkeley?

If so, would someone kindly share with me their Makefile.

Thanks.

Hi Mat. In a paper on using Cuda 5.0, Brent Leback used as an example the generation of DD values. Would you mind asking him for a copy of his Makefile - particularly any parts related to invoking qd-2.3.14, and then either post it or email it to me.

Thanks.

Hi Malcolm,

I asked Brent about this. He just use a few functions from the ddfun90 package since they are written in Fortran, making it easier to convert to CUDA Fortran. He didn't use QD since it's written in C++. Also, he didn't use a makefile, though all the code examples are available from links in the article.

For those interested in using DD precision the following commands are useful for generating compiler flags and linker flags:

"dd-config --fcflags"
"qd-config --fclibs"
