Bear is a 12 node research computing cluster. [http://groups.haas.berkeley.edu/HCS/research_computing/research-hwsw.html The official blurb] says that bear has two sets of 5 compute nodes, one set with 64Gb of RAM per node, and one with 16Gb of RAM per node. Nodes have dual core 3Ghz Xenon processors.
To find out this information yourself (and for other reasons), you'll like to be able to shell on to a node. I currently can't (I get permission denied requests). You can dispatch a shell command to a node through bsub though!
For the record, the IP addresses are:
*Bear (login node): 128.32.67.85, 128.32.67.86, 192.168.1.42, 192.168.1.43, 10.1.1.42, 10.1.1.43
*cn-01 to 10: 10.1.1.101 to 10.1.1.110
The following commands are valuable:
free #list memory available
cat /proc/meminfo #see the memory specs
cat /proc/cpuinfo #see the chip specs
uname -a #see the system info
/sbin/ifconfig -a #see the network tables
There are three ways of using bear:
*'''cd bulk''' - change into the bulk directory
*'''cd ..''' - change up a directory
*'''top''' - look at the top processes
*'''ps -aux''' show all processes running
