GnuPG (GNU Privacy Guard) is a tool for creating key-pairs, used for encrypting and signing messages. It therefore provides a means to guarantee a your identity online and protect sensitive information. A key-pair is a mechanism for asymmetric encryption. It consists of a private key and a public key. The public key is shared and is […]
As computing hardware evolves, increasing core counts mean that memory bandwidth is becoming the deciding factor in attaining peak performance of numerical methods. High-order finite element methods, such as those implemented in the spectral/hp framework Nektar++, are particularly well-suited to this environment. Unlike low-order methods that typically utilise sparse storage, matrices representing high-order operators have […]
A hybrid parallelisation technique for distributed memory systems is investigated for a coupled Fourier-\spectralhp element discretisation of domains characterised by geometric homogeneity in one or more directions. The performance of the approach is mathematically modelled in terms of operation count and communication costs for identifying the most efficient parameter choices. The model is calibrated to […]
FCGID allows PHP to run outside of the Apache process. It also allows the PHP process to run as the user who owns the scripts. This is useful for WordPress as it allows the installation of plugins and themes without the need to enter FTP credentials. To get it running is sometimes tricky as it […]
