SHADOWFAX: Meeting VII postponed due to make up week (trials and tribulations of using openMPI and g++ on a Fedora based cluster)
Today's Aim: g++, where fore art thou, g++?
Tonight's Reading: Building Parallel Programs, Chapter 7
This Week's Research: installing g++
Attending Thurs: JeremyA, SteveB, DevinB
This Thursday we will 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???
