This post is gathers information about OpenFOAM 2.0.x build times, using the gcc version that comes with Ubuntu 10.10, namely 4.4.5.

_____________ This was initially posted here: _____________

Since I was curious about using N+1 processes, I've built OpenFOAM 3 times on my machine that has 8GB of DDR2 800MHz and one AMD 1055T X6, using Ubuntu 10.10 with its original gcc version:
  • 1st build with 6 processes;
  • 2nd

Trying to include glibc in my build-gcc scripts...

If you don't know what I mean by build-gcc, read this first: Automated scripts for building gcc 4.4.x and 4.5.x for using with OpenFOAM 1.7 series

Sometime ago, a problem was detected when using one of my build-gcc scripts (see OpenFoam 1.7.0 on RHEL 4.6 post #3) about no valid being found during the build procedure. This was later fixed by adding the proper lib folder path to LD_LIBRARY_PATH (read post #9 on that thread).
