Developments to the imaging computing system

2007/02/06 Delayed Software Documentation

Dan has been very naughty and not documented changes he made to the load balancing software. I updated (with Matthew Brett's help) several features of the software setup. We setup the Freesurfer and MNE scripts to source Freesurfer and MNE when they balance the load. We also setup so it will pass the SUBJECTS_DIR and SUBJECT variables. In order to ensure that the FSL version differences don't affect Freesurfer (which uses FSL), I have changed the way FSL works. FSL is no longer sourced by default. Each user who wants to use FSL needs to source FSL in each terminal window via the following scripts.

fsl_3.2_setup
fsl_4.0.1_setup

I'm sure there are some other details I have left out add questions here and I will fill out the replies. [DGW]

2007/12/12 Added FSL 4.0.1

To use, type

fsl_4.0.1_setup

at the Linux prompt

2007/12/10 Tweaked load display

The load displayed when typing showload, or on launching SPM or MEG software was a bit verbose. I trimmed it. [RC]

2007/12/07 Updated MRIcro for Linux

Updated MRIcro to 1.39 build 4. Type startmricro & at Linux prompt to launch

[RC]

2007/12/05 Linux server OS version upgrade

Major upgrade. Linux servers l08-l21 upgraded to RedHat Enterprise Linux 4, and added to pool of machines used by default to run SPM 5 (under Matlab 7.3) and MEG.

Thanks very much to Rob Anthony for handling this so smoothly!

[RA]

2007/11/27 Updated load sharing back end, added load monitoring commands

New commands:

Type at Linux prompt

Description

showload

Shows load across all machines

bestmegmachine

Returns the machine currently loafing most

[RC]

2007/11/27 Control verbosity of output when starting spm or meg software

  • If you want the scripts to print less verbose output when you launch commands do
    • mkdir ~/.loadshare
    Then one of
    • touch ~/.loadshare/verbose_less
    or
    • touch ~/.loadshare/verbose_silent

[RC]

2007/11/27 MEG wrapper update

All previous Elekta commands and many new ones (e.g., maxave, maxfilter) are now called through a new wrapper. All arguments are passed straight along to the command, which will be launched on an appropriate machine. Start a new xterm to bring them into path. [RC]
