compile issues with undefined references to mkl commands (that appear in the relevant folders)

[dgrin1]

I'm trying to install ctf on a linux box, first loading my openmpi module, then running this config command ./configure CXX=mpicxx --build-scalapack --build-hptt --with-hptt --with-scalapack --with-lapack 'LD_LIB_PATH=-L/opt/intel/compilers_and_libraries_2019.5.281/linux/mkl/lib/intel64 -Wl,--no-as-needed' 'LD_LIBS=-lmkl_scalapack_lp64 -lmkl_gf_lp64 -lmkl_intel_thread -lmkl_core -lmkl_blacs_intelmpi_lp64 -lmkl_def -liomp5 -lpthread -lm -ldl' --install-dir=~/lib/

Then removing all -ipo commands (they were causing compiling issues), then running make, and then make install. This all works, fine, but when I try to run make test or make testpython, the compiler crashes and gives errors liek these: erbla': pxerbla.f:(.text+0x66): undefined reference to for_write_seq_fmt' pxerbla.f:(.text+0x7f): undefined reference tofor_write_seq_fmt_xmit' pxerbla.f:(.text+0x9a): undefined reference to for_write_seq_fmt_xmit' pxerbla.f:(.text+0xb3): undefined reference tofor_write_seq_fmtxmit' /home/dgrin/ctf/scalapack/build/lib/libscalapack.a(pjlaenv.f.o): In function `pjlaenv': pjlaenv.f:(.text+0x3e): undefined reference to `for_cpystr'

I was able to get much further on my OS laptop, but the svd tests would not work there. Any tips?

This looks like an issue with scalapack symbols. Running configure with --build-scalapack will download and build ScaLAPACK at configure time, but you are also providing MKL ScaLAPACK symbols. One or the other should be workable but not both together. I also cannot comment on the specific list of MKL symbols needed, as these are architecture dependent (would recommend MKL link line advisor, likely you are already using that). Also configuring with --no-static or --no-dynamic will build only dynamic (necessary for Python) or only static (sufficient for C++ without dynamic linking) libraries, which may simpplify things and avoid errors.

[dgrin1]

Thanks, that seems to help, but then this error message rears its head,

/Users/dgrin/ctf/scalapack/BLACS/SRC/igsum2d_.c:153:7: error: implicit declaration of function 'BI_imvcopy' is invalid in C99 [-Werror,-Wimplicit-function-declaration] BI_imvcopy(Mpval(m), Mpval(n), A, tlda, bp->Buff);

I'm guessing this is a simple swap to a different compiler, but I'm not sure how to proceed.

[solomonik]

I would recommend to make sure ScaLAPACK built correctly when CTF's configure executed and to try to run some of the tests included in the ScaLAPACK package. There may be issues with missing libraries or the BLAS/MKL/OpenBLAS library ScaLAPACK is trying to use. You may ultimately need to build it separately (or can try the MKL ScaLAPACK). CTF also builds without ScaLAPACK, but will not include functionality related to interfacing to ScaLAPACK routines for solving systems of equations and eigenvalue computations, all sparse/dense tensor contraction functions should work without it.

[dgrin1]

I was able to avoid this problem by running configure after installing fresh lapack, openblas, and scalapack, and leaving scalapack build off the configure. I was then able to run make, and make install. Now when I run my python calculation that uses ctf it behaves until I try to an SVD, at which point it seg faults (with an 8X8 matrix and no nans in it).

When I try to generate make test, make python_test, or make svd, I get lots warnings about "Undefined symbols for architecture arm64: "_Cblacs_barrier", referenced from: CTF_SCALAPACK::cblacs_barrier(int, char*) in libctf.a(lapack_symbs.o)" (many like it).

Ultimately, these makes crash of the form, clang: error: linker command failed with exit code 1 (use -v to see invocation) make[1]: *** [/Users/dgrin/ctf/bin/test_suite]

I think somehow the libraries are only partially pluigged in at this point.

Thoughts?

[solomonik]

This is expected, using SVD requires Scalapack.

[dgrin1]

Sorry if I was unclear - what I meant to say was that I built scalapack, separately but still included it via --with-scalapack in the config run. So in principle, SVD should work, no?

[solomonik]

I see, then yes, understood your post as leaving off scalapack altogether. Please send output from configure and make python_test.

(accidentally clicked close and post, reopened)

[dgrin1]

I tried two approaches -- A) Approach A - local build of scalapack

./configure CXX=mpicxx --build-scalapack --with-scalapack --with-lapack --install-dir=~/lib/

Then the configure gave the output

and successful make and make install commands

After that I tried make python, which generated many of these warnings, ipo: warning #11012: unable to find -l-mkl mpicxx -pthread -shared -Wl,-z,relro -Wl,-z,now -g -Wl,-z,relro -Wl,-z,now -g -L/home/dgrin/ctf/lib_shared /home/dgrin/ctf/lib_python/ctf/term.o -L/usr/lib64 -lctf -lscalapack -l-mkl -lpython3.6m -o /home/dgrin/ctf/lib_python/ctf/term.cpython-36m-x86_64-linux-gnu.so -L/home/dgrin/ctf/lib_shared -qopenmp -O3 -ipo -L/home/dgrin/ctf/scalapack/build/lib -Wl,-rpath=/home/dgrin/ctf/scalapack/build/lib ipo: warning #11012: unable to find -l-mkl ld: cannot find -l-mkl ld: cannot find -l-mkl ld: cannot find -l-mkl ld: cannot find -l-mkl error: command 'mpicxx' failed with exit status 1
