Q&A

Q-1 Not enable PBS option in job script
A-1Not enable "#PBS" in PBS's job script after program and command.

bad exmaple
[sgiadm@ismaltx template]$ #!/bin/csh
#PBS -q q8
cd /home0/sgi/prog1
Below all comment(Not enable "#PBS")
#PBS -N job_name
#PBS -j oe
#PBS -m ae
#PBS -l ncpus=1
./a.out

good exmaple
[sgiadm@ismaltx template]$
#!/bin/csh
#PBS -q q8
#PBS -N job_name
#PBS -j oe
#PBS -m ae
#PBS -l ncpus=1

cd /home0/sgi/prog1
./a.out

Q-2 Greeking in the SJIS code file
A-2 Please change SJIS code to EUC. Command : nkf -e file-name
Q-3 Not compile automated parallelization with Intel Compiler automated parallelization option(-parallel).
A-3 Sometime not compile automated parallelization with Intel Compiler. Automated parallelization is depended program. In terms of automated parallelization, VAST/toOpenMP may be even better than Intel Compiler.
Q-4 Then submit job with qsub command, job status(qstat) is 'E' and output is noting.
A-4 This problem often is occuerd mistake configuration file(.cshrc .tcshrc .profile .login etc). Try "mv configuration file".
exmaple
[sgiadm@ismaltx]$ mv .cshrc .cshrc.org
Q-5 Display "Warning", after use SCSL Library(LAPACK) with C.
A-5 Because of SCSL's LAPACK can't support C/C++ interface, FOTRAN's interface directly call. Therefore, not problem and ignore this Warning
Q-6 Job killed without realizing on ismaltx
A-6 ismaltx is limited 2hours(CPU TIME). Therefore, aggressively use Batch system(PBS).
Q-7 How to link MPI Program with SCSL Library
A-7 Link SCSL
MPI Program --> -lscs
OpenMP Program --> -lscs_mp
Q-8 How to check batch program's standard output and standard error output
A-8 Use redirect for program in job script.
