Linking to BLAS and Pardiso

Rawlins__David — Tue, 24 Feb 2009 01:02:32 GMT

I'm having problems linking to the BLAS and Pardiso on a linux IA64. Here is my compile command (I've added some carriage returns to make it legible):

____________________________________________________

icpc -o febio.alt -DLINUX -DPSLDLT -DSUPERLU -DPARDISO
-I/home/sci/rawlins/Projects/SuperLU_3.1/SRC/ -I.. *.cpp -O3
../lib/fecore_altix.a
/home/sci/rawlins/Projects/SuperLU_3.1/lib/libsuperlu_3.1_altix.a

/usr/sci/LinuxIA64/intel/mkl/lib/64/libiomp5.a
-lpthread -L/usr/lib -lscs_mp -mp
_____________________________________________________

And here is a sample of the errors I'm getting:
______________________________________________________

/usr/sci/LinuxIA64/intel/mkl/lib/64/libmkl_core.a(blklu_unsym_ooc_lp64.o)(.text+0x37f2): In function `mkl_pds_lp64_blklu_unsym_ooc_pardiso':

: undefined reference to `mkl_blas_lp64_dgemm'

Any help would be appreciated.

Thanks,

please try to use the following linking line:
ifort myprog.f -L$MKLPATH -I$MKLINCLUDE -lmkl_solver_lp64
-Wl,--start-group $MKLPATH/libmkl_intel_lp64.a
$MKLPATH/libmkl_intel_thread.a $MKLPATH/libmkl_core.a -Wl,--end-group
-liomp5 lpthread
Where, for example,$MKLPATH=/opt/intel/mkl/10.1/lib/64

Gennady,

Thanks for the quick reply. What should MKLINCLUDE point to?

Thanks, I think the grouping did the trick.

Using your suggestion below worked a couple of weeks ago, but I'm running into similar problems again. Here is my compile command and a sample of the errors I am getting:

I tried to repeat the issue without succes.All is ok on my side.
I uploaded to this tread makefile and pardiso.f i used for reproducing the issue.
You can try to use these files as well.
please let me know mkl's Package IDinstalled ( see ../doc/mklsupport.txt file )

The package ID is l_mkl_p_10.1.1.019. I've been preoccupied with other projects, but I still have not been able to get this to compile.

Gennady,

I played around a bit more with your instructions and got things working. Thanks again for your help.
