I am trying to run pcgamess on skif supercomputer of MSU.
I use the following distribution "Direct PC GAMESS/Firefly version 7.1.F download links, Linux MVAPICH/libibverbs, dynamically linked NPTL-based version" since its the only one MVAPICH based distribution available for download.
I run firefly using the following options:
$CONTRL SCFTYP=RHF RUNTYP=OPTIMIZE NPRINT=7 MULT=1 ICHARG=-1
MAXIT=1000 COORD=UNIQUE LOCAL=NONE $END
$SYSTEM MWORDS=256 TIMLIM=2700 $END
$P2P P2P=.TRUE. XDLB=.TRUE. $END
$STATPT NSTEP=200 OPTTOL=0.0001 $END
$STATPT METHOD=GDIIS HESS=CALC $END
$BASIS GBASIS=N31 NGAUSS=6 NDFUNC=0 NFFUNC=0 NPFUNC=0
DIFFSP=.FALSE. DIFFS=.FALSE. $END
$GUESS GUESS=HUCKEL $END
$DATA
...
$END
Firefly starts without complaints on 64 nodes. Since I use non-direct method it creates 64 folders to store the data.
The problem is that they are all almost empty - 3.7MB constantly per folder. I have no output to PUNCH file (!) and my .out file contains only first input cards echo.
Nothing seems to change during 24 hours run. In the end when duration exceeds time limit jobs hangs without any output.
What is wrong with my job? Any suggestions?
Thanks. I appreciate your time.
