Timeline


Annual proactive maintenance

Friday, 17th April 2015 @ 9:30 am

In order to ensure that Superior and Portage continue to operate consistently at a high level, IT will be performing proactive maintenance work starting at 8 am on Tuesday, 5th May 2014.

All nodes -- including the front end, login and storage nodes -- will need to be powered down. Any running simulation at that time will be automatically terminated without further notice.

As such, researchers are requested to complete (or at least checkpoint) their simulations, and transfer any necessary data to a local workstation so that analysis, visualization, and manuscript preparation work can still be continued.

Superior and Portage should be accessible as before starting at 8 am on Friday, 8th May 2014.

MuSTI adds 64 more processors

Thursday, 8th May 2014 @ 2:01 pm

Multi-Scale Technologies Institute (MuSTI) has added four more CPU based compute nodes to Superior, forming musti.q (a higher priority queue for MuSTI researchers with a lower priority access to everyone else) and taking the overall compute capacity to nearly 31 TFLOPS.

Multi-scale technologies are those that bring together functional elements to form systems where the relative size of components within the system spans from the nano through the micro and into the macro domain. The systems focus of the MuSTI emphasizes the challenges associated with integrating technologies that have relative feature sizes orders of magnitude apart and operating characteristics that are size dependent. This presents many problems that must be addressed by interdisciplinary teams of researchers using specialized equipment.

Research focuses on engineered systems and components such as nanoelectronics, nanosensors and systems, and associated materials. MuSTI is home to interdisciplinary nano- and micro-technologies education programs -- such as an interdisciplinary minor in Nanoscale Science and Engineering. The establishment of MuSTI is based on Michigan Tech's focus on applied research, established practices of interdisciplinary research, capabilities in testing, and strong engineering and science programs.

While pre-compiled software suites might continue to run as before, researchers will experience errors when attempting to compile newer (versions of) software suites.

Monday, 23rd December 2013 @ 5:10 pm:
Intel compilers are available as before.






A message from CTO

Friday, 20th December 2013 @ 3:00 pm

A number of computers on campus have been compromised; as a result, some username/password combinations have been recorded and sent off campus. If you have received notification that you need to reset your password please proceed immediately to login.mtu.edu and do so.

If you have used the same password for other sites you should reset those as well. Please note that this compromise involved a number of Linux servers and that SSH (secure shell) access to them may be temporary blocked or rerouted as those machines are being secured.

Detailed information is here.






qresources

Thursday, 31st October 2013 @ 9:45 pm

Researchers may use this utility from within qgenscript or by itself to get real time information about the number of licenses (total, in use and available) for each software suite.






Custom serial jobs via qgenscript

Monday, 28th October 2013 @ 7:30 pm

qgenscript now generates the necessary job submission script to run any custom program in serial fashion. It does not, however, support the Array Jobs feature yet.






BASH and Python via qgenscript

Tuesday, 22nd October 2013 @ 3:30 pm

qgenscript now provides an option to generate the necessary job submission script for BASH and Python (version 3.3.2). These do not, however, support the Array Jobs feature yet.

This is intended to help submit post-processing tasks (especially the ones that take longer than 4 hours and as such, do not fit within qlogin session) to the queue, akin to any other simulation.






Array Jobs

Wednesday, 29th May 2013 @ 5:05 pm

qgenscript now offers a new but optional feature with which users submit a large number of jobs (say few tens, hundreds or even thousands) via one batch submission script. The need for this feature and its advantages are described in the Array Jobs section.

As of now, this feature is only available and has been tested successfully for the following software suites: all versions of LAMMPS, serial version of MATLAB and, R. Users are strongly encouraged to test this feature for smaller/test cases before proceeding ahead to run real ones.

If users need more information about this feature and/or if the scenario is more complex than the simple one described in the Array Jobs section, please contact Information Technology Services.






LAMMPS 2013.05.23

Thursday, 23rd May 2013 @ 5:20 pm

Newest version of LAMMPS (marked 2013.05.23 in qgenscript) is now available for use.

qgenscript now also lists all previous versions of LAMMPS. As such, users are encouraged to be cautious in selecting the appropriate one.






Exclusive Compute Node Access

Monday, 13th May 2013 @ 3:10 pm

qgenscript now offers a new but optional feature with which users may request exclusive access to a compute node (for any job with up to a maximum of 8 processors).

Advantage: If chosen, a job will be sent to a compute node that is completely free, and no other job will be assigned to that node until that given job is completed. This feature will satisfactorily handle CPU and/or memory intensive jobs.

Disadvantage: If chosen, a job will very likely wait in qw mode for longer than usual while the queuing system finds a node that is completely free. This feature, for normal jobs (i.e., not CPU and/or memory intensive), will hog the entire node and prevent it from being used by other normal jobs. If chosen for a job with more than 8 processors, it will never run and stay in qw mode forever.






Mathematica 9.0.1

Wednesday, 8th May 2013 @ 2:29 pm

Mathematica 9.0.1 is now available for use. Users may run qgenscript to generate the required SGE script.






Power Outage

Tuesday, 30th April 2013 @ 1:50 pm

Please note that facilities will be performing a high voltage switchgear inspection and repair on campus (more information). In light of this work, the cluster will need to be shut down gracefully to avoid potential damage to the hardware.

As such, users are requested to checkpoint any/all simulations and stop them (use qdel JOBID command) by 11 am on Sunday, 5th May 2013. The cluster is expected to be inaccessible until noon on Wednesday, 8th May 2013.

Should the aforementioned inspection and repair work take longer than expected, users will be informed via the cluster's mailing list.






Smarter qgenscript

Thursday, 4th April 2013 @ 1:31 pm

Please note that qgenscript will not henceforth be prompting to choose a specific compute node in case of parallel computations.

Based on the usage statistics gathered so far,an overwhelming majority of jobs have used 8 or less processors. As such, qgenscript now offers a maximum of 8 processors for any parallel job.

It has been made smart enough to not spread a parallel job across multiple physical nodes - especially for those computational suites for which scratch files/folders have been localized (to reduce communication overhead and improve the overall performance).






Two Factor Authentication

Thursday, 28th March 2013 @ 12:16 pm

Looking for volunteers to test the Two Factor Authentication set up on wigner. The set up expects that the user has a smart phone (Android or iPhone) with Google Authenticator app installed. The app is free and may be downloaded/installed using the following links:

If willing to help test this set up, please reply to the email message sent to the wigner mailing list to receive further information.






Power Outage

Tuesday, 12th February 2013 @ 4:00 pm

You will be notified as and when the facility is powered on and becomes available for use.






NAS Node

Wednesday, 18th April 2012 @ 6:43 pm

A network area storage (NAS) node, worth about 2 TB, has been added to wigner.it - /state/partition2/research/ from the NAS node is mounted across the cluster [front end, login and compute nodes] at /research/.   Users are strongly suggested to run any/all I/O intensive computations from their respective research folders, found under /research/$USER/.






pauli.phy --> wigner.it

Monday, 9th April 2012 @ 9:22 pm

pauli.phy (along with its compute nodes) has been retired and replaced with wigner.it - in its current form, it includes a front end (wigner.it), a login node (wigner-login.it), 8 compute nodes (each with 8 CPU cores and 8 GB RAM).   Users' data on pauli.phy has been moved over to wigner.it as is - users will need to SSH into wigner-login.it.mtu.edu and may use the cluster as they did pauli.phy.
