Accessing ScaLAPACK
mpiCC [options] file ... /opt/mlib/lib/[pa2.0|pa20_64]/libscalapack.a −lcl −lm
Replace libscalapack.a with libscalapack.sl on your compiler command line
if you want to link the shared library on a PA-based system.
3. Use the −lscalapack option on the compiler command line that links your
program, preceded by:
−Wl,–aarchive_shared,−L/opt/mlib/lib/[pa2.0|pa20_64]
For example, the command lines in Method 2 for PA could be written:
mpif90 [options] file ... −Wl,–aarchive_shared,−L/opt/mlib/lib/[pa2.0|
pa20_64]
−lscalapack
mpicc
[options] file ... −Wl,–aarchive_shared,−L/opt/mlib/lib/[pa2.0|pa20_64]
−lscalapack −lcl −lm
mpiCC
[options] file ... −Wl,–aarchive_shared,−L/opt/mlib/lib/[pa2.0|
pa20_64]
−lscalapack −lcl −lm
4. Set the LDOPTS environment variable to include:
–aarchive_shared,−L/opt/mlib/lib/[pa2.0|pa20_64]
For example:
setenv LDOPTS “–aarchive_shared,–L/opt/mlib/lib/pa2.0”
Then use the −lscalapack option on the compiler command line that links
your program:
mpif90 [options] file ... −lscalapack
mpicc
[options] file ... −lscalapack −lcl −lm
mpiCC
[options] file ... −lscalapack −lcl −lm
NOTE An LDOPTS specification takes precedence over using -Wl on the
compiler command line. That is, if you use the LDOPTS environment
variable to specify a library path, you cannot override that specification
with a -Wl option on your compiler command line.
5. To link with the ScaLAPACK8 libraries on a PA-based system, use the
+DA2.0W option to specify memory addresses are 64-bit.
Compile Fortran applications with the +i8, +autodbl, or +autodbl4 option
where:
• +i8 promotes 4-byte integer of logical constants, intrinsics, and user
variables (declared as integer or logical) to 8-byte quantities.
• +autodbl promotes all integer, logical, and real items to 8 bytes, and all
double-precision and complex items to 16 bytes.
