• A FORTRAN77 code won't compile because the following statement is not understood:
  

  open(35,file='/home/npast/SHOCK/MEANFLOW/RUN_Mp0.72_Tp2.14_Ms1.36/interp_info.dat')
  

  The path to the file interp_info.dat is too long. However (!), if I have a similar statement inside a FORTRAN90 code, it will compile and run fine. Also, if I shorten the above line to, say,
  

  open(35,file='/home/npast/SHOCK/MEANFLOW/interp_info.dat')
  

  it will compile and run fine again.

• If you have been trying to use SGE from the command line (ie qsub, qstat etc) and it doesn't work, it is because your PATH is trying to use the commands in the directory
  

  /usr/local/bin
  

  For some reason the commands in this directory don't work, and instead you need to use the commands located in
  

  /opt/gridengine/bin/lx26-amd64
  

  These ones will work. I have just rearranged my PATH variable in my .login file so that it looks in this directory first, before looking in /usr/local/bin.
  Here is the way I have set my PATH variable in my .login file:
  

  /bin:/usr/bin:/usr/X11R6/bin:/usr/local/pgi/linux86-64/6.2/bin:/opt/gridengine/bin/lx26-amd64:/ opt/openmpi/pgi/bin:/usr/local/bin:/usr/local/tecplot360/bin:.

• A FORTRAN code compiled as:
  
  pgf90 -Mfree -mp -o main_omp.out -O2 subn_omp.f main_omp.f
  
  The computation blows up in Aster. Had to reduce time step to stablize the computation. The same code runs with no problem on IBM SP4.

• Connect to aster by:
  
  ssh -X pamd.scs.fsu.edu
  ssh -X aster
  
  Then launch Tecplot. It works. But after a while, if I relaunch tecplot, it shows 'Err: Cannot open display ', and Tecplot doesn't show up. Have to quit the connection and reconnect to aster again. (Ju)
