Dear all,
following the discussion at PETSc'16, I have tried to render the
TeX-based manual into HTML with latex2html [1] and pandoc [2] .
Neither attempt was successful, because of the presence of certain
external TeX packages used for rendering various custom aspects of the
manual.
There is
ed
me initially.
So my question becomes: please synchronize the output of ./configure
--help with manpages and pdf manual :)
Thanks again,
Marco

Good morning,
Does the HDF5 functionality need to be explicitly requested at
configure time? I just noticed that my default configuration on a
single-node machine does not compile any relevant symbol.
I do not have HDF5 installed on my system yet, but I assumed PETSc
includes it by default, or

presenters, but first and foremost the PETSc team, the sponsors and
our excellent host Karl.
Hoping to meet you soon again, perhaps at PETSc'17,
Kind regards,

Dear all,
I'm struggling with this statement:
"It is recommended that you call both of the above preallocation
routines [MatSeqAIJSetPreallocation and MatMPIAIJSetPreallocation] for
simplicity."

I saw that,
estimate for a compatible release of SLEPc ?
Thank you and kind regards,

Dear all,
I have a simple code with a matrix filling, assembly and output to stdout.
This in turn is wrapped within a SLEPc bracket, and that in turn in a
PETSc bracket, both called with default options
(`XInitializeNoArguments`).
I run this on my laptop, MPI comm size == 1.
Issue: _sometimes_ t
Hi Satish,
thank you for the input;
I was really looking for something that lets one abstract out "where"
the code lives, so as to possibly work both in a single-node and
cluster setting.
This is why a "container" approach sounds meaningful. Configure once, run many.

Dear all,
has anyone here tried/managed to install PETSc on e.g. Amazon AWS or
the Google Compute Engine?
I believe some extra components are needed for coordination, e.g.
Kubernetes or Mesos (in turn requiring that the library be compiled
within some sort of container, e.g. Docker), but I'm a
Dear all,
Is anyone here aware of linear program solvers, of any form, being
implemented on top of PETSc ?
Thank you in advance,
Marco
Hi Venkatesh,
it sounds like a job for the batch scheduler; again, a "bash" problem,
with some additional variables:
On a RHEL cluster, I was using Torque/PBS, which gives the `qsub`, `qstat`
commands. I would guess that Cray has analogous ones .
PETSc and SLEPc are instead toolkits for splitti
Currently, I'm re-building fblaslapack and mpich along with PETSc for both
cases, but would it be possible to share either between the two builds?
Thank you,
Marco
What construct can I use to build and keep track (i.e. map over) a
staggered index set, i.e. the dual (vertices, elements) meshes for a FEM
application.
I am looking for the equivalent, on a regular mesh, of the `sieve`
construction (

Thank you, but this is not really helping;
why are there two slots to supply the Jacobian of the same function, i.e.
Amat and J ?

The signature of SNESSetJacobian is
PetscErrorCode SNESSetJacobian(SNES snes,Mat Amat,Mat Pmat,PetscErrorCode
(*J)(SNES,Vec,Mat,Mat,void*),void *ctx)
however it would seem redundant to supply both a constant matrix and a
function to compute the Jacobian.
The manual says of J "(if NULL then SNES

Thank you for the reply;
let me improve my question: in e.g. a FEM code, we need:
*) a mesh table :: [element -> [face -> [edge -> [node] ] ] ]
*) one or more reference elements with associated basis over elements
and/or faces and Jacobians, or a quadrature rule to represent
integration over
Hello,
I'm looking for some non-optimized PETSc code; namely, I struggle a
bit with generalizing the provided examples. On one hand inlined
elementary operations help keep track of the FLOPs but make for
hard-to read code.
For instance, KSP example 2, (
