Distributed parallel programming in Python : MPI4PY
Author: Akshay Pai •
Tags: programming •
Comments: 1 MPI stands for Message passing interface. An implementation of MPI such as MPICH" or OpenMPI is used to create a platform to write parallel programs in a distributed system such as a Linux cluster with distributed memory. Generally the platform built allows programming in C using the MPI standard. So in order to run Parallel programs in this environment in python, we need to make use of a module called MPI4py which means "MPI for Python". This module provides standard functions to do tasks such as get the rank of processors, send and receive messages/ data from various nodes in the clusters.

Comments: 2 How to setup Single Sign On with OTP using simpleSAMLphp and privacyIDEA This howto will deal with Single Sign On to web pages. Maybe you know OpenID. Similar to Kerberos a "Ticket" is granted to the user to authenticate at other services using the ticket and not the credentials anymore. In this howto we will use SAML (Security Assertion Markup Language) which is more sophisticated than the simple OpenID. SAML can be used to setup trust relations between several entities. This is why it is used between companies and organizations, why online service are using it.

How to run your own Git server with GitlabHQ on Ubuntu 14.04

Comments: 5 How to run your own Git server with GitlabHQ on Ubuntu 14.04 This document describes how to install and configure Git and GitHub. These are great tools to manage and administer a whole host of Git repositories and the associated permissions. So, these remain true blessings for users writing open source software, however, when writing a closed source software may not be comfortable in trusting the code to a third party server. To gain the much-needed flexibility and control on stuff like Github/BitBucket without hosting the git repositories on servers that lie external to the control of users, GitLab remains a Godsend!
