Let the Editor Wars Begin!
Editors, particularly command-line editors, are an important tool for high-performance computing systems administrators. We point out some editor options with little to no bloodshed.
Fast Help
Quickassist technology offloads computationally intensive compression and encryption tasks to provide a performance boost for Intel processors.
Optimizing Your NFS Filesystem
NFS is probably the most widely used shared filesystem. You can turn many knobs to boost performance, ease management, and improve security.
Ceph Jewel
The Ceph object store remains a project in transition: The developers announced a new GUI, a new storage back end, and CephFS stability in the just released Ceph v10.2.x, Jewel.
A Container for HPC
Working with containers in high-performance computing can be difficult; a new container named Singularity comes to the rescue.
Finding and Recording Memory Errors
Memory errors are a silent killer of high-performance computers, but you can find and track these stealthy assassins.
Getting the Most from Your Cores
CPU utilization metrics tell you how well your applications are using your processing resources.
How Persistent Memory Will Change Computing
Persistent memory is non-volatile data storage in DIMM format. Losing power means that you won't lose data. What is it, and how can you use it?
Parallel I/O
Understanding the I/O pattern of your application is the starting point for improving its I/O performance, especially if I/O is a fairly large part of your application’s run time.
