[petsc-dev] syntax for multiple libs (eg, --with-blaslapack-lib/a --with-blaslapack-lib/b)

Satish and Matt, What is the syntax multiple libraries? I have this now but need to addd more files. Thanks, Mark '--with-blaslapack-lib=/opt/intel/compilers_and_libraries_2018.1.163/linux/mkl/lib/intel64/libmkl_intel_thread.a',

Barry, sorry for the delay... but your patch solved the problem! thanks! Eric Le 18-06-21 à 16:12, Smith, Barry F. a écrit : Fixed in barry/fix-petscstrlcat/maint I also doubled the length of the work strings used in processing options so your options won't get truncated and hence

[petsc-dev] (no subject)

The problem with this code from package.py is it rejects a package for a large variety of reasons but cannot print which reason it is rejecting it! Thus we waste hours and tons of emails debugging something that doesn't need to be debugged. Barry # if user did not request option,

Re: [petsc-dev] GAMG and custom MatMults in smoothers

Thanks for the MWE. But it behaves exactly as I would anticipate, see log. I think that naming the event differently for each rank is not good but fortunately PETSc just ignores this for rank > 0. Important is the event id which is the same. I correctly get that the time spent in this event is

Re: [petsc-dev] GAMG and custom MatMults in smoothers

The intent was not to show you a deadlock; was to provide you evidence that the PetscLogEvent model is meant to have the same event created collectively (hopefully at class registration) on all processes. See also PetscLogViewDefault 2018-07-02 18:45 GMT+03:00 Vaclav Hapla : > Thanks for the

Re: [petsc-dev] GAMG and custom MatMults in smoothers

OK, now I got you. So I think it's actually not that important when they are created but whether and in which order they are registered on different ranks (see attached edited MWE). Yes, that's a relevant concern I must admit, mainly for things working with subcomms.ThanksVaclav[0] event1
