This is my first time using high performance machine. Although the machine is only for student, and of course, it is not good as those pro machines, it is still a good experience for me. ssh remote machin, returns:

GCC version 4.3 c,c++,fortran and java module load gcc PGI version 7.2 & 8.0, 64 bit compilers (C,C++,F77,F95,HPF) module load pgi Intel version 10.1 & 11.1, 64 bit compilers (C,C++,Fortran) module load intel MPI, OpenMPI libraries, default 1.2.9, 1.3 available module load pgi openmpi module load gcc openmpi mpicc or mpif90 to compile mpirun to execute. qsub -pe dmp8 16, to submit a 16 slot mpi job openMP is available in pgi, intel and gcc QUEUES and PEs: os: 160 slots main queue (overbooked) -pe dmp NN, distributed on nodes, 16 slots per node (4 cores) -pe smp NN, shared memory, 1 single node for up to 16 threads (4 cores) User Limits: The login nodes are intended for short test runs only, max cputime is 30min INTERACTIVE: Use qsh to request a interactive job and recive a xterm. e.g. qsh -l h_rt=01:00:20 **NB qlogin dont work at the moment use qsh** (Use qlogin to execute an interactive session without starting a xterm. ) NB X-forwarding is working! (If you have logged in with "ssh -X os.uppmax.uu.se" !!!) Dont forget to request h_rt * * * News: 2009-11-20 os6 restarted due to system problems 2009-10-7/8 Service stop New file server "bubo" introduced for all uppmax storage. Your home directory is now in /bubo/home/h?/user. Refer to this using "$HOME" in your programs. To ease the transition we have defined symbolic links so that the old directory names are usable for a short time. 2009-07-07 Compilers: PGI is updated to 9.0, default is kept as 8.0 If you want the latest version use "module load pgi/9.0" Intel is updated to 11.1 (build 038), 11.0 (build 084) is kept as default If you want the latest version use "module load intel/11.1" 2009-03-17 Infiniband removed from openmpi due to stability problems\n 2008-11-28 OS-kluster is reinstalled with SL 5.2 R is now a module to run R please load the module first "module load R" Sun Grid Engine updated to 6.2 I use bold font to indicate hardware.
