Since the file system is full, we would be running a script on 20th April 2015 in Virgo, which would clear all the files and folders in the scratch except the directory of the current running job. So make sure you don't keep any useful data in the scratch.
Note : There is no backup for scratch folders by HPCE team.

License registration process will be started for intel.
20th March, 2015
This is a survey which would facilitate Computer Center to get information about the users using institute's licenses for executing any of the pre/post/solver of the commercial software (wherever applicable). This will help CC to plan Renewal/Purchase of licenses.
All license usage will be on 80:20 basis.(80% from the departments and 20% from Computer Center).
Form needs to be submitted on or before 20/3/2015.
Only on registration, licenses will be made available by the license server and without registration licenses will not be available for Institute's commercial software running in Computer Centre.
Those who have already registered for intel compilers, need not register again for the same.
All the users of the commercial applications listed in the registration form are requested to register in the link below

As you may have observed the file systems on Virgo have been rather unstable. We have been in touch with IBM to sort out this issue. IBM claims that they have identified the problem with GPFS and will start working on it from Tuesday the 15th of January onwards. They expect to complete the task by the end of the week.
Virgo will not be available to the users during this period from 15th to 20th of Janaury 2013.
Inconvenience caused is regretted.

The IB Network of the Virgo cluster has Some problem & IBM is working on this.
As soon as the system is ready we will inform you.
The problem is temporarily solved. But the cause of the problem is not known and the system is under observation.
Duration of availability cannot be guaranteed till the cause is known and solved.
There is some filesystem issuse, IBM Engineers are working on it and it should be shorted out shortly.
We will upated you the status, once the issue is resolved.
Inconvenience caused is regretted.

Happy to announce that the new IBM cluster VIRGO will be available to the users from Tuesday, 16-10-2012.
Please ssh to virgo.iitm.ac.in to access this machine. Since this is a new system there may still be some issues that need to be addressed and the machine may need reboot at short notice. The users are therefore requested to submit only short jobs for the first two weeks.
IBM is still working on the scheduler and will take some more days to complete it.Hence we have powered on the IB Cluster of Vega and will run it for 10 days.All queues except high memory queues will be allowed in IB Cluster.
This is just a temporary arrangement .
Once Virgo is ready, it will be released to users.
