ftp access to the data storage system disabled
Due to changes in the security policy the port 21 (ftp) has been disabled on the computer cluster. The scp access is available for data copying to and from the cluster, as well as the WWW access
GNU Multiple Precision Arithmetic Library now available
GMP library is now available at the cluster. GMP (the GNU Multiple Precision Arithmetic Library) is the free open source library for arbitrary precision arithmetic, operating on signed integers, rational numbers, and floating point numbers. GMP is part of the GNU project and is distributed under the GNU LGPL. The main target applications for GMP are cryptography applications and research, Internet security applications, algebra systems, computational algebra research, etc.
User guide for Git (version control system) available
Section "For users" now contains the short user guide for the version control system Git
WWW access to the data storage system
WWW interface to the data storage system is now available in the test mode at http://82.196.66.9/websds/
New resource manager SLURM
In order to make the resources of the cluster more available, the resource manager has been changed. User guide for SLURM (in Russian) can be found in the "For users" section. For troubleshooting please contact the support service:cluster@krc.karelia.ru.
Limits on the number of launched tasks
Beginning from 02.02.2011 each user can launch not more than 3 tasks, occupying in total not more than 8 nodes; additionally, each user can launch 8 single-processor tasks.
Students that study parallel programming and use the cluster for practice can launch not more than 3 tasks under the time limit of 5 hours. These tasks in total cannot occupy more than 2 nodes (16 processors).
New IP address of the computer cluster
