The Ohio Supercomputer Center (OSC) is experiencing an email delivery problem with several types of messages from MyOSC. 

 OSC is preparing to update Slurm on its production systems to version 23.11.4 on March, 27.

On July 12th, 2016 OSC migrated its old GPFS and Lustre filesystems to new Project and Scratch services, respectively. We've moved 1.22 PB of data, and the new capacities are 3.4 PB for Project, and 1.1 PB for Scratch. If you store data on these services, there are a few important details to note.

Bowtie2 is an ultrafast and memory-efficient tool for aligning sequencing reads to long reference sequences. It is particularly good at aligning reads of about 50 up to 100s or 1,000s of characters, and particularly good at aligning to relatively long (e.g. mammalian) genomes. Bowtie 2 indexes the genome with an FM Index to keep its memory footprint small: for the human genome, its memory footprint is typically around 3.2 GB.

Octave is a high-level language, primarily intended for numerical computations. It provides a convenient command-line interface for solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with Matlab. It may also be used as a batch-oriented language.

Octave has extensive tools for solving common numerical linear algebra problems, finding the roots of nonlinear equations, integrating ordinary functions, manipulating polynomials, and integrating ordinary differential and differential-algebraic equations. It is easily extensible and customizable via user-defined functions written in Octave's own language, or using dynamically loaded modules written in C++, C, Fortran, or other languages.

While our Python installations come with many popular packages installed, you may come upon a case in which you need an additional package that is not installed. If the specific package you are looking for is available from anaconda.org (formerlly binstar.org), you can easily install it and required dependencies by using the conda package manager.

ARM HPC tools analyze how HPC software runs. It consists of three applications, ARM DDT, ARM Performance Reports and ARM MAP: 

  • ARM DDT: graphical debugger for HPC applications.
  • ARM MAP: HPC application profiler with easy-to-use GUI environment.
  • ARM Performance Reports: simple tool to generate a single-page HTML or plain text report that presents overall performance characteristics of HPC applications.

Sometimes the best way to get access to a piece of software on the HPC systems is to install it yourself as a "local install". This document will walk you through the OSC-recommended procedure for maintaining local installs in your home directory or project space. The majority of this document describes the process of "manually" building and installing your software.

miRDeep2 is a completely overhauled tool which discovers microRNA genes by analyzing sequenced RNAs. The tool reports known and hundreds of novel microRNAs with high accuracy in seven species representing the major animal clades. The low consumption of time and memory combined with user-friendly interactive graphic output makes miRDeep2 accessible for straightforward application in current reasearch.
