Meeting VIII - New mini cluster with 64 bit Fedora 12 DVD
Today's Aim: more g++, where fore art thou, g++?
Tonight's Reading: Building Parallel Programs, Chapter 8
This Week's Research: new mini Fedora 12 DVD cluster
Attending Tues: ALL
This Tuesday we will again take stock of what we've done and what needs to be done. For example, we got a Hello World program (hello.c) working over our Fedora based cluster using openMPI and gcc. This is a great accomplishment!
However, when we tried to do this with C++ (hello.cc) we found that g++ was not installed! I did not realize that the 64-bit Fedora 11 CD we used for installation had GNU GCC with only gcc installed. Usually, GNU GCC has gcc, g++, gf77, etc. A lot of room on the CD is taken up with GNOME and Compiz. So, we tried to yum install gcc but found the mirrors were down or missing or blocked? Some of our nodes have some strange networking issues, so yum is fubarred on some.
