Using Workspaces to Develop Simulation Tools

Learn how to use workspaces to develop simulation tools and collaborate with other researchers. Accessible from any web browser, workspaces provide a full-featured Linux desktop and access to grid resources. Close your browser and your workspace will still be running, allowing you to pick up where you left off. Easily manage files, resize your screen, and share your workspace with others.

  2. Getting into a Workspace

  3. local clusters File server What is a workspace? • Full-featured Linux desktop • For tool developers • For researchers • Accessible from any web browser • Still running after you close your browser • Access to Grid resources • File storage provided by the hub

  4. Close the browser Still running, and listed under “my sessions” Accessing running workspaces

  5. Close the workspace Closes the session Closing workspaces OR

  6. Click and drag Type in a new size Press Tab Resize the screen

  7. Pop out as a separate window Get rid of this header and see more of the workspace Solve problem of mouse trails e.g., MacOSX/Firefox

  8. Pop out as a separate window Click Popout again to pop back in This area goes blank. Closing this window also closes the popup.

  9. See same screen at same time Check this if you don’t want to share control Enter the login for your friend Share your screen myfriend

  10. Linux Cheat Sheet ls patternlist files in the current directory ls list all files ls *.xml list files ending with .xml mkdir namemake a new directory called name mkdir assmt3make a new directory calledassmt3 cd namechange working directory cd assmt3 change to directory assmt3 cd .. change to parent directory cd change back to home directory (good if you get lost) cp from tocopy filefromto fileto cp /apps/rappture/current/examples/zoo/number/tool.xml . cp ../assmt3/tool.xml newtool.xml gedit fileedit the specified file rappture run Rappture (loads tool.xml by default) rappture -tool foo.xml / = separates directories . = current directory .. = parent directory * = matches anything ? = matches single char

  11. Editors “Start” menu

  12. Other utilities xloadimage file view image file xpdf file PDF viewer gimp & image editor dx & scientific data explorer octave & MATLAB clone xcalc & calculator

  13. Developing tools • See instructions: • in your project area at wiki/GettingStarted • Subversion tutorial • Rappture tutorial • Use Subversion to check out project source code • svn checkout https://yourhub.org/tools/yourtool/svn/trunk yourtool • Edit, compile, test • cd src • make install • cd ../rappture • vi tool.xml • rappture

  14. Downloading Files • Easy way to download files: • exportfile tool.xml • exportfile examples/*

  15. Uploading files • Easy way to upload files: • importfile src.tgz

  16. Uploading files • Easy way to upload files: • importfile src.tgz • importfile mesh.dat doping.dat

  17. Other ways to transfer files Secure FTP (sftp) sftp client, such as PUTTY http://www.putty.org/ yourlogin@sftp.yourhub.org Drag & drop on the desktop (webdav) • On Microsoft Windows: • Go to My Network Places • Click Add a network place • Internet or network address:https://nanohub.org/webdav

  18. Accessing the Grid spice3 local clusters Launch jobs on the grid If you would have typed… spice3 –b indeck > out.dat …then submit the job to the grid as: submit spice3 –b indeck > out.dat submit --venue steele spice3 –b indeck > out.dat

  19. Exercise #1: Using Workspaces • Log in and launch a workspace • Bring up your favorite editor and create a file called hello.txt with thetext: Hello, World! • Export the file to your desktop • Import another file back into your workspace Hint: look at commands… exportfile --help importfile --help
