"Grid Confinement" - A Physicist perspective

Image
The following post should not be taken too seriously!

If GridComputing is so good but what we see practically is a complete chaos in the Data Center then there must exist an Anti-Grid that cancels all its benefits.
If one tries to make an order and to split the Data Center into two separate sites then immediately Grid - Anti-Grid pairs are produced out of the vacuum and chaos is being restored.

Social Networks and Grid Computing - Some similarities

There are some similarities between Social Networks, e.g. Facebook and Grid Computing.
In the table below I mention a few.

Mounting a memory stick under Linux

A short reminder for myself and for all those who are lost when no auto mount works:

1. Verify that the device is recognized in 'dmesg', write down the device name. e.g. /dev/sdb
2. mkdir /disk_on_key
3. mount -t vfat /dev/sdb /disk_on_key
4. at the end un-mount by: umount /disk_on_key

Good luck!

GSS authentication failure - A question to the gt-users mailing list

I posted today the following question:

I installed Globus version gt4.0.4-x86_64_rhas_4-installer on an Opteron node running CentOS 4.4.
output of uname -a is:
2.6.9-55.0.2.ELsmp #1 SMP Tue Jun 26 14:14:47 EDT 2007 x86_64 x86_64 x86_64 GNU/Linux

In the globus-gatekeeper.log there is the following error message:

TIME: Thu Oct 25 18:16:50 2007
PID: 14589 -- Notice: 6: globus-gatekeeper pid=14589 starting at Thu Oct 25 18:16:50 2007

GSS authentication failure
GSS Major Status: General failure

PID: 14589 -- Failure: GSS failed Major:000d0000 Minor:00000002 Token:00000000

I would appreciate any help resolving this problem
