Do I need2 flelm running, one in a unix computer and one in a windows computer or can I just have 1 installed in a windows computer for both UNIX fortran and Windows fortran.
You need seperate licenses for the Intel Visual Fortran Compiler Professional Edition for Windows* and Intel Fortran Compiler Professional Edition for Linux* , they are sold as seperate products. More info at http://software.intel.com/en-us/intel-compilers/
In case you have purchased two floating point license for these two products and you want to use the same Flexlm server that is possible. It can be Windows* or Linux* server. You still need a seperate license for the Windows* and the Linux* product.
