It’s the Little Things
Several very sophisticated tools can be used to manage HPC systems, but it’s the little things that make them hum. Here are a few favorites.
Resource Monitoring For Remote Applications
Remora combines profiling and system monitoring to help you get to the root of application problems by revealing its use of resources.
Multiprocessing in Python with Fortran and OpenMP
Creating Python modules with Fortran OpenMP code makes all available cores accessible to Python functions.
ClusterHAT
Inexpensive, small, portable, low-power clusters are fantastic for many HPC applications. One of the coolest small clusters is the ClusterHAT for Raspberry Pi.
SquashFS
If you are an intensive, or even a typical, computer user, you store an amazing amount of data on your personal systems, servers, and HPC systems that you rarely touch. SquashFS is an underestimated filesystem that can address that needed, but little used, data.
Parallel I/O for HPC
In the last of three articles on HDF5, we explore performing parallel I/O with the use of HDF5 files.
How Old Is That Data?
The explosion of data is a storage burden that all system administrators bear. The agedu tool lets you discover what data is being used.
Hierarchical Data Storage for HPC
HDF5 is a data model, library, and file format used primarily for scientific computing to store and manage data.
Modern Fortran for Today and Tomorrow
Fortran development is still progressing, with a new version scheduled to release in 2018. In this article, we look at Fortran 2008 and the upcoming Fortran 2015.
