Sun HPC Campus Ambassador @ CESUP/UFRGS Glaucio Souza

Wanting to learn about Solaris and OpenSolaris? The Tech Outreach team at Sun has created a great new Solaris online training course entitled, Introduction to Solaris and opensolaris.org.

The course covers an introduction to opensolaris, Java Desktop System, Service Management Framework, Solaris Containers, ZFS and DTrace. I believe that with this course you can have an good idea of what Solaris can offers to improve your computing experience.

The course is located at: http://sunstudentcourses.com

NetBeans 6.1 Beta Supports Tighter MySQL Integration

March 17, 2008 - Sun announced the immediate availability of NetBeans 6.1 integrated development environment (IDE) Beta. NetBeans 6.1 Beta adds features for JavaScript technology development, a key component for delivering Ajax web applications and tighter integration of MySQL database functionality.

Read the NetBeans 6.1 Beta Press Release.

From Monday 10th to Thursday 13th, CESUP (National Center of SuperComputing) at the Federal University of Rio Grande do Sul, where I work as Campus Ambassador, hosted a course of OpenMP. Our fellow ambassadors Maria Cecilia and Joseanderson, traveled long seven hours from Maceió to Porto Alegre and presented us a magnificent course.

This course was not a normal talk for it was a recorded one, designed to be a online course avaliable at the web-learning plataform hosted by CESUP.

After four days of hard work, they finished the recordings and the fine adjustments. We even had time for a little happy hour at Lima e Silva, a famous local street for its bars.

And of course we had to take some pictures:

If you updated your SGE installation from a version prior to 6.1, you may have noticed that when you use the qstat command, only your jobs are shown. This is the new behavior of the qstat command.

In case you want to view all jobs, just add "-u *" (without the quotes) to the $SGE_ROOT/$SGE_CELL/common/sge_qstat file, which will change qstat behavior for all your cluster or to do the modification for a specific user, create a $HOME/.sge_qstat file for that user, adding the same content.

That will produce the same result as execute the qstat -u "*" command.

You can learn more at sun.docs.com and at DanT's GridBlog, from where I've found that information.

Other day, I was trying to install a software that I've downloaded and oops, it was an iso file. As I didn't wanted to burn a cd, I tried to mount the file. But how can I do that on Solaris?

After questioning the oracle (Google) I found an answer! Use the “lofiadm” command to create a block device for the image and then use “mount” to mount it as a filesystem, as the following:

Make the block device with “lofiadm”:
lofiadm -a /path/to/your/image.iso /dev/lofi/block_device_number

Mount the image as a read-only filesystem:
mount -F hsfs -o ro /dev/lofi/block_device_number /mountpoint

It's important that you use the full path to both the iso file and the mount point, otherwise it won't work.
