Hi everyone, Sorry if this is a FAQ, or is unrelated to this group, it's the ONLY cray group that I can find and I'm new to the Cray world. Our group is thinking about porting code to a Cray supercomputer and I need to find out whether the Cray supports C++. If anyone is experienced with this or can help, I would greatly appreciate it!

The system is based on AT&T CFront which translates the code to C. Then, SCC compiles the code. This works out quite well for the Cray as C++ programs are able to take advantage of SCC's optimization capabilities. In particular, all loops in one of our codes vectorize. CRI has apparently started officially supporting C++ (with version 3.0 of CFront). This is a good news-bad news thing: the good news is that they've added some fairly useful extensions and pragmas; the bad news is that they are now charging a hefty price for the compiler.
