Please note that INTJ is unable to provide contractors to Australian government agencies. INTJ only provides contractors to Australian corporate clients.
Our HPC Contractors provide HPC technical support to Australian corporations via skype, in person visits, via the telephone, via email or any other communication medium which is suitable for you. We can be engaged on a short term paid hourly basis to help fill in the gaps in your HPC technical support services. INTJ's contractors are already employed full time and provide services to you via INTJ outside of normal 9-5 business hours. This means for all practical purposes that we will engage with you mostly during lunch breaks, after 5:00 pm and for those big problems you face that require more time and effort to resolve - on Saturdays and Sundays.
When dealing with INTJ you are dealing with a team of technical experts who will go the extra mile to help you to solve the technical issues you are experiencing in the HPC area. Our HPC experts have a minimum of a Bachelors Degree in Computer Science, Software Engineering, High Performance Computing or equivalent as well as extensive skills and hands on experience supporting High Performance Computing Systems. Our people have significant, hands on experience with Linux. We have extensive programming skills developing linux shell scripts as well as additional experience administering Git, Subversion and Artifactory repositories. Some of our contractors also have an excellent understanding of Computational Fluid Dynamics as well as experience supporting scientists who use Fluent, OpenFOAM, Pointwise, Tecplot and Fieldview to solve and analyse problems that involve fluid flows.
Our people have extensive skills in Linux System Administration and Scientific Software Support and have been personally hand selected by Clarke Towson who has a background in Computer Science and is a full time HPC System Administrator with 16 years of experience in technical support and scientific computing. Clarke is not a recruiter so you can be confident that INTJ's people are of a very high technical caliber and did not win their place on Clarke's team by salesmanship or people skills. They won their place by technical merit. Our people are not 'suits'. We are "nerds nerds" so to speak and grew up with and developed an obsession with technology.
Our HPC contractors can provide System Administrative Activities like installing Linux operating systems, adding users and groups, configuring yum repositories, installing and configuring multimedia packages on CentOS, partitioning hard drives, configuring RAID arrays, adding storage and other desktop Linux support activities. Administration and maintenance of GIT, Subversion, Artifactory and other code repositories to ensure effective management of the HPC code environment. Downloading, installing, configuring, compiling and licensing scientific applications. Updating scientific applications on lab Linux PC's and on HPC global file systems.
Additional services we can provide including administration and support of HPC queueing systems including Torque, PBS, Maui, Moab and SLURM. Installing the Flexnet licence manager, installing and updating licence files for OpenFOAM, Pointwise, Tecplot & Fieldview and updating licence management software. Logging HPC related system support calls with Cray and HP Enterprise. Packaging up and returning faulty compute nodes back to Cray and HP, liaising with Cray and HPE support technicians and HPC management on outstanding technical issues, monitoring compute nodes, rebooting compute nodes as required, rebooting entire clusters as required, startup and shutdown of clusters on a scheduled basis, monitoring of scientists HPC jobs, investigation of job logs to determine causes of job crashes and other faults, administration and monitoring of HPC systems using Cray ACE Management or HP cluster management software.
We can help you to monitor HPC infiniband networks, bring networking systems up and down as required, investigate networking faults that cause jobs to fail, replace faulty infiniband cables, install and configure as required Mellanox switches as well as perform monitoring of storage space on cluster storage arrays, licence servers and individual lab Linux PC's, partitioning hard drives of lab PC's, configuring RAID arrays, adding storage, updating firmware on storage array hardware. Support of parallel file systems (Lustre, some GPFS / Spectrum file system testing for research activities) as well as writing effective and clearly understood documentation detailing HPC system administration and support.
Our HPC contractors can provide Programming Activities like writing shell scripts to support HPC activities, PBS queue monitoring scripts, operating system and application monitoring scripts in order to extend and monitor open source vendor applications. Writing scripts to work around bugs in open source vendor supplied applications as well as OpenMPI programming for support of scientific job scripts particularly for OpenFOAM and ANSYS Fluent job scripts.
INTJ's Contractors can also help you to resolve difficult and complex problems which crop up from time to time with cluster queueing systems and other complex problems which require significant investigation, analysis and innovative solutions.
