MUMPS requires more memory

[paulflang]

I just pushed c7cf5f31036030c7905d91306e05de6874514d78 to the multi_exp branch. I think the new code should correctly translate the PEtab problem specified in Disfit/tests/fixtures/G2M_copasi to a Julia JuMP problem (see DisFit/julia_code.jl). Unfortunately, when running the optimization I seem to run out of memory. @sshin23 : do you have any suggestions of how to solve this?

MUMPS returned INFO(1) = -9 and requires more memory, reallocating.  Attempt 1
  Increasing icntl[13] from 1000 to 2000.

  Increasing icntl[13] from 2000 to 4000.

Made necessary changes in jump_script.jl in a1869ba. Could you make the corresponding changes in core.py?

Also, it would be helpful to include a bash or python script for this example.

Thanks a lot. I'll make the changes to core.py.

Do you mean a script to run the translation of PEtab to JuMP?

Hi Paul,

Yes. Sorry if it was already in the repo and I wasn't finding it.

Thanks, Sungho
