When I type charmrun, it says:
you must set BL_HOME environment variable.
Setting BL_HOME to any value including
/bgl/BlueLight/ppcfloor/, the result changed to:
charmrun: line 39: [: -nt: unary operator expected
Running on 1 processors:
charmrun: line 47: /BlueLight/bin/CIORUN: No such file
or directory
charmrun: line 47: /BlueLight/bin/CIORUN: cannot
execute: No such file or directory
I googled CIORUN, it seems belong to BGLsim. Since I
am running program on real BG/L, why should it still
try to use CIORUN?
NAMD compilation is finished after removing -ldl from
BlueGeneL.tcl and using fftw within machine. (Newly
compiled fftw gives an error: undefined reference to
`__ctype_b_loc') Howerver, when I test with just
typing namd2, it tells me: illegal instruction.
Will this comilation be really useable?
