This way you can access the files on trillian from your client machine. Of course, you can give it a different name. You will see a new file system named 'trillian' on your machine. Sshfs -o Ciphers=arcfour -o idmap=user $HOME/trillian To do so, make sure the 'sshfs' package is installed on your machine. The lustre file system on trillian cannot be NFS mounted, but it is possible to create a mount point in 'user space' for which no root access is required. This can happen in two ways: (1) move the data using ftp, scp, or rsync (the latter is the most convenient and most efficient), or (ii) provide remote access. Since trillian is not necessarily a good platform for analysis and visualization of these data, it is often necessary to access data from workstations. Simulations on trillian will typically leave large amounts of data on the lustre file system.

That uses MPI calls to run multiple instances of the same code with different parameters. If there is a need for running many identical one-core jobs in parallel one should write a wrapper code There is a good reason for that,īecause otherwise if one allowed multiple jobs on one node, these may get into each other’s wayīy competing for resources such as memory or I/O bandwidth. The smallest allocation unit on Trillian is one node, i.e., 32 cores.

Dave is also the Cray person to ask the really tough questions. Here is a bunch of videos and a tgz with example from Dave Strensky.

all home dirs are on Lustre file and is usually 96% full or higher so be mindful of your disk space usage.

there are currently no queue limits, but users should keep #tasks < 1000 for the time being.

you need to start executables with 'aprun' even for serial codes, otherwise they run on the login node!.

do NOT use the login nodes for computation other than compiling, etc.Ĭd /home/space/jraeder/THM-DF-20120703-trillian-test01Īprun -n 178.

the batch system is PBS (qsub, qstat, qdel and friends).

GCC, CRAY, INTEL, and PGI compiler suites are available, with the typical libs (mpi, hdf5).

Trillian was installed June 11/12, 2013 and began production about a week later. Trillian was acquired through a NSF Major Research Instrumentation (MRI) grant, with cost sharing from the UNH Space Science Center, Senior Vice Provost for Research, the College of Engineering and Physical Sciences (CEPS), and the Research and Instrumentation Center (RCI). The rate was P48.70:$1 a year ago.Īt the end of June in the previous year, there was P11.16 trillion in total outstanding debt, of which P7.93 trillion sourced through domestic borrowing and P3.22 trillion from external sources.Trillian, a CRAY XE6m-200 at UNH for the simulation of space plasma and fluid flow The exchange rate used to compute the data was P54.97 to $1, which was less favorable than the P52.41 to $1 used in May. The BTr said commercial loans made up 55.4 percent of all external debt, while multilateral and bilateral loans made up 34.2 and 10.5 percent of that obligation, respectively. The bureau also noted that due to 'the impact of local currency depreciation against the USD (US dollar) amounting to P186.94 billion and the net availment of external financing amounting to P43.18 billion offsetting the P35.72 billion effect of net depreciation against the US dollar on third-currency denominated obligations,' the country's external debt widened by 5.1 percent, to P4.02 trillion from P3.83 trillion.
