Padding my SVN stats before the end of the year. Also should be fixing the
failing regression tests which would pass without the -exact flag.

this a run time configurable option.

Pruning the "don't reset the grid option", not used in years, but responsible
for consuming trillions of floating point operations. Also cleaned up some
compiler warnings.

Fixed warnings, removed a slug of deprecated code related to the so-called
"momentum form" which never seemed to give better answers than the standard
form. Cleaning up to make way for code that might be more useful, XPIC(2).

jbhooper 2016-12-14 12:39 Rev.: 56104

Rework the reaction/diffusion component to:

1) More clearly dilineate which code file does what
2) Implement a standardized ScalarDiffusionModel interface (not to be confused with a particle's diffusion interface) that must be provided for any standardized diffusion model

Both of these aid in the implementation of the Bazant diffusion/kinetics model

Interpolators now return the number of entries that need to be looped over
in the code that calls them. Currently, this number is the same as the d_size
for all of the interpolators except the fastCPDI. fastCPDI previously only allo
wed the hash function to reach 27, but now it can go as high as 64, but it
usually will not. This commit doesn't change any answers in MPM, IMPM or
MPMICE.

The main changes in this commit only effect a simulation when <outputNthProc> is
set (> 1) in the .ups file.

This commit allows for PIDX output on every process for a time step
output, while using every Nth process (if so specified) for UDA
checkpoint output. Eventually the need for this Nth Proc changing
hack (and Nth proc output itself) should go away when PIDX fully takes
over I/O.

Note, when using "Nth Process Output", both a checkpoint and a time step save
CANNOT occur on the same time step. Therefore the time step output is postponed
for one time step.

On a slightly different note, we use the term proc badly... we should use process,
or perhaps better yet, rank... as proc is usually taken to mean "processor", but
in MPI's case, means process - and the term MPI uses for process is rank.

D CCA/Ports/LoadBalancer.cc
D CCA/Ports/LoadBalancer.h
A + CCA/Ports/LoadBalancerPort.cc
A + CCA/Ports/LoadBalancerPort.h

- Renamed from LoadBalancer to LoadBalancerPort to avoid confusion with the LoadBalancer itself.
- Added "setNthProc()" so that the SimulationController can change the value as needed.

M CCA/Components/DataArchiver/DataArchiver.h
M CCA/Components/DataArchiver/DataArchiver.cc

- Added postponeNextOutputTimestep(). This pushes off the output of a time step by one
time step. (This occurs if using Nth Process Output and a checkpoint and a time step
where to occur on the same time step.)
- Added savingAsPIDX() boolean query function so that the SimulationController
can avoid doing all of this hack when we are not using PIDX.
- Removed "getCurrentTimestep()" and "getCurrentTime()", as, per the documentation on them,
they should not be used anyway; you should get this info from the shared state. Note,
the DataArchiver name (getCurrentTime()) is different from the shared state name
(getElapsedTime()) which was also confusing.
- Pass const string parameters by reference.
- White space cleanup / alignments.

- If the input file has no <save> labels, but specifies an output interval, throw an exception.
- If the 'logname' is not available when running a simulation, put 'unknown' instead of ignoring.
Should probably find a better fix then 'unknown', but that will have to wait for another day.
- Swat some evil endls. :)
- Don't calculate 'currsecs' on every process, just on rank 0.
- Removed all calls to usingMPI() as Alan deprecated it in a recent commit.
- procOnLevel is (I hope) a boolean array... so declare and use it as such.
- Don't name a variable with a single letter. n -> var_cnt

- Did I mention white space cleanups... Please for the sake of older eyes...

"1 process output" (for time steps) when running with PIDX (and nth process is > 1).

Reorganize the way we include MPI. Previously files were including the mpi_defs.h (configure generated file) to get mpi.h. Now they
include UintahMPI.h (from Core/Parallel/).

Note: MPI is now required (though for all intents and purposes it already was). You can still run a serial version of the code,
you just must compile/link with MPI first.

M configure
M configure.ac

- Fix check for xml2-config.
- Fix check for mpi.h location when using 'built-in' (fixes issue with non-mpich MPIs).
- Check to see if MPI handles const correctly.
- Fix some indentation.
- No longer define HAVE_MPI or HAVE_MPICH as we require MPI now.
- Added defines for MPI_CONST_WORKS, and MPI_MAX_THREADS and MPI3_ENABLED (thought the last 2 are hard-coded and need
to have configure tests written for them).

M include/sci_defs/mpi_testdefs.h.in

- Added MPI_CONST_WORKS, MPI_MAX_THREADS, and MPI3_ENABLED #defines.
- Moved the MPI wrappers into UintahMPI.h (thus out of this configure generated file).

D include/sci_mpi.h

- Removed sci_mpi.h as it is not used and its only purpose was to allow for compilation without MPI. This
is no-longer allowed (and probably hadn't worked in a long time).

A Core/Parallel/UintahMPI.h

- Added the new file UintahMPI.h which is used to #include <mpi.h> and wrap the MPI calls.
- These wrappers were in mpi_testdefs.h.
- Replaced most of the "const" with MPICONST so that on non-const-compliant MPIs they
can be turned off (this is done through a configure check).
- Grouped a lot of the UINTAH_ENABLE_MPI3 sections into single #if's instead of having a #if for each line.

M CCA/Components/Arches/fortran/sub.mk

- Remove tabs from where they are not supposed to be.

M StandAlone/tools/mpi_test/mpi_hang.cc
M StandAlone/tools/mpi_test/mpi_test.cc
M StandAlone/tools/fsspeed/fsspeed.cc

- Proper indentation.
- Replaced mpi_defs.h with UintahMPI.h.
- Use <> for includes and not "" per Uintah conding standard.
- Added comment for the #endif of the #ifndef compiler guard for the .h file.
Moved some #ifndef .h compiler guards to the very top of the file.

M testprograms/Malloc/test11.cc
M testprograms/Malloc/test12.cc
M testprograms/Malloc/test13.cc

- Fix indentation.
- "__linux" doesn't exist on some systems, so added "__linux__".
Probably could remove the __linux, but not sure so I didn't.

M VisIt/libsim/visit_libsim.cc

- Use #include <>.

M StandAlone/sus.cc

- Remove the code for old MPI versions. We don't support MPI v1 any more.

Redirect all MPI calls through the lightweight wrapper (header only)

This allows for standardized error checking and easy collection of runtime stats. All MPI funtions can be called from the wrapper by replacing:

MPI_ with Uintah::MPI::
e.g.
Uintah::MPI::Isend(...)
Uintah::MPI::Reduce(...)

Also enables MPI3 wrappers when MPI3 is available and protects against these when not. Will want MPI3 for non-blocking collectives. MPI3 is availalbe on Mira but not Titan yet.

* Note src/scripts/wrap_mpi_calls.sh has been added to the src tree. This has the sed foo to do this replacement src tree-wide.

* Have tested this with OpenMPI, MPICH, IntelMPI and also built on Titan and Mira.

ahumphrey 2016-06-07 09:19 Rev.: 55420

Removal of src/Core/Thread and related refactoring throughout the code-base.

This is the first step in a series of infrastrucutre overhauls to modernize Uintah. Though this all passes local RT (both CPU and GPU tests), I expect some fallout we haven't considered and will be standing by to deal with any issues. Once the dust settles, we will move to replacing Core/Malloc with jemalloc.

* We are now using the standard library for all multi-threading needs within the infrastructure, e.g. std::atomic, std::thread, std::mutex, etc.

* The Unified Scheduler is now the only multi-threaded scheduler, e.g. ThreadedMPIScheduler no longer exists (though the source will soon be placed into an attic).

* Threads spawned by the Unified Scheduler are detached by default (not joinable), allowing for easy, clean and independent execution. There are no longer ConditionVariables used to signal worker threads, just a simple enum for thread-state.

* What was Core/Thread/Time.* is now Core/Util/Time.* - a next step will be to migrate all internal timers, etc to use std::chrono.

* NOTE: Though much cleanup has occurred with this commit, there is still significant cleanup and formatting to be done. The scope of this commit neccessitates a more incremental approach.
