UKy HPC - README FIRST

High Performance Computing

May 13, 2008

03/30/07 : Per previous announcements, the SDX/XC systems are no longer available. Old SDX accounts and files have been migrated to the new IBM system ( BCX ).

The IBM cluster login nodes can be accessed at: bcx.uky.edu
In order to authenticate (login) to the new IBM Intel commodity cluster (bcx.uky.edu) you must use your Link-Blue (aka e-Dir) password. Note: your HPC and Link-Blue account name must match! If they don't match, contact the Help address below. Once you login the first time, you may set up an ssh public key to authenticate from then on if you desire (or continue to use your Link-Blue passwd). Please change your default password with the passwd command.
The BCX (commodity cluster) nodes have 8GB of memory (each); ie 2GB per core. If your memory requirements for non-distributed code exceeds that, you will have to port your code to the P-series (PowerPC) SMP machines.

To see important system related notices, use the sysstatus command when on the system.

BCX - Intel commodity cluster

To compile Fortran (F90), use ifort (Intel Fortran).
To compile for OpenMPI use mpif90,mpicc
BLAS and LAPACK functions are available via the Intel MKL libraries.
To link with Intel MKL, use -L$(INTEL_MKL_LIBS) in your makefile along with: -lmkl
To link LAPACK, link MKL above along with: -lmkl_lapack
Intel MKL docs here: /share/cluster/SLES9/x86_64/apps/intel/mkl_docs.d

P-series - large SMP

Note: LSF is no longer the batch software; LSF has been replaced by Moab+SLURM ; see the examples above.
bjobs (LSF command) is not currently available; use showq or squeue to check jobs.
To kill a job:

The HP VED editor is no longer available; the closest replacement we have at this time is NEdit.
