The nodes for STAR's grid-related activities at BNL are as follows:

Color coding

  • Black: in production (please, do NOT modify without prior warning)
  • Green: machine was setup for testing particular component or setup
  • Red : status unknown
  • Blue: available for upgrade upon approval
Grid Machine Usage Notes Hardware Make and Model OS version,
default gcc version
Hardware  arrangement OSG base Condor
stargrid01 FROM BNL, submit grid jobs from this node   Dell PowerEdge 2950

dual quad-core Xeon E5440 (2.83 GHz/ 1.333 GHz FSB), 16 GB RAM
RHEL Client 5.11,

gcc 4.3.2

6 x 1TB SATA2:

1GB /boot (/dev/md0) is RAID 1 across all six drives

There are 3 RAID 1 arrays using pairs of disks (eg. /dev/sda2 and /dev/sdb2 are one array).  The various local mount points and swap space are logical volumes scattered across these RAIDed pairs.

There are 2.68 TB of unassigned space in the current configuration.

NIC: 2 x 1Gb/s (one in use for RACF IPMI/remote administration on private network)

OSG 3.2.25 Client software stack for job submission 8.2.8-1.4 (part of OSG install -- only for grid submission, not part of RACF condor)
stargrid02 file transfer (gridftp) server Attention: on stargrid02, the mappings *formerly* were all grid mappings (i.e. to VO group accounts: osgstar, engage, ligo, etc...)

On May 17, 2016, this was changed to map STAR VO users to individual user accounts (matching the behaviour of stargrid03 and stargrid04).
  This behavior may be changed back. (TBD)

stargrid0[234] are using the VDT-supplied gums client (version 1.2.16).
stargrid02 has a local hack in condor.pm to adjust the condor parameters for STAR users with local accounts.


All nodes have GLOBUS_TCP_PORT_RANGE=20000,30000 and matching firewall conduits for Globus and other dynamic grid service ports.
