In the second article of this three-part series, we look at simple write examples in Fortran 90 and track the output with strace to see how it affects I/O patterns and performance. ... common in HPC to illustrate these differences: C, Fortran 90, and Python (2.x series). I run the examples on a single 64-bit system with CentOS 6.2 using the default GCC compilers, GCC and GFortran (4.4.6 ...

. The simple MPI used is the classic 2D Poisson equation solver, poisson_mpi , which I procured from an online set of Fortran 90 examples. HPCCM HPC Container Maker (HPCCM) was used to create the specification
