Re: [wsjt-devel] wspr two-pass decoder status and .c2 file problem
Thanks Bill,
For what it’s worth, here a link to the VERBOSE build capture:

Here’s the CMakeCache.txt:

Looks like this is a known issue with the qt4-mac port. I'll install it
on my Mac VM and see if I can find an easy workaround.

The problem seems to be that the compiler is getting the
/opt/local/include path ahead of the stuff included via the
CMAKE_PREFIX_PATH. That shouldn't be happening.
I suggest that a fresh build tree and configure with CMake followed by a
CMake build adding ' -- VERBOSE=1' to the end of the build command.
Capture the output and post it somewhere I can have a look at it along
with the CMakeCache.txt file from the build tree root.

Thanks, John. I’ve been meaning to ask you and/or Bill for advice. I do all of
the wsprd development on my Mac, but I have never been able to get wsjt-x to
compile. I get stuck when compiling /lib/ipcomm.cpp. I have to resort to an
Ubuntu 14.04 virtual machine if I want to test wsjt-x on the mac.
I think that my problem may have to do with having qt4 installed via macports
(for gnuradio) and a separate installation of Qt5 for wsjt-x.
I’ll include the error messages below. I have Qt5 installed per the
instructions in the “INSTALL” text file. I have no idea why it is looking in my
/opt/local path. I used the following cmake command:
cmake -D CMAKE_PREFIX_PATH="~/local/qt-macx-clang;~/Builds/hamlib3.0" -D
CMAKE_INSTALL_PREFIX=~/Builds/wsjtx_install ~/Builds/wsjtx
Any suggestions would be much appreciated!

It basically boils down to how you can break the work to be done into independent chunks that can be processed in parallel. The independence is key here, if a chunk of work X can be divided into two or more completely independent chunks Y and Z, ... then there is a gain to be had if the time for splitting X, executing the longer of Y and Z, ... and recombining the results of Y and Z, ... is less than the time to execute X alone. If Y and Z are not truly independent then there is an added overhead for communication between them, usually in the form of some form of synchronization constraint. This is also where the cost of complexity can overwhelm any gains as synchronization constraints are a huge source of defects and maintenance costs. The rest is implementation detail. >>> Steve k9an >>> >> 73 >> Bill >> G4WJS. -- Monitor 25 network devices or servers for free with OpManager!

My current thinking is that spectral shape (peaks and mins) should be ignored
altogether, because almost anything can happen when two or more signals with
carrier frequencies within a few Hz of one another are superposed.

The snr_min that I’m using corresponds to -33 dB in 2.5 kHz bandwidth, or -7 dB
in the bandwidth occupied by the WSPR signal. We know from much experience
(both with real signals and with simulations) that we are not going to decode
anything weaker than this.

Re: [wsjt-devel] wspr two-pass decoder status and .c2 file problem
It is interesting to see how far we’ve come. I just analyzed my favorite .wav
file with several versions of the decoder:
1. wspr0 from python-based wspr: 7 decodes
2. current wsprd from wsjt-x 1.6: 10 decodes
3. wsprd_exp with subtraction and two-passes:16 decodes
4. no-peak-requirement modification to wsprd_exp: 19 decodes

Re: [wsjt-devel] wspr two-pass decoder status and .c2 file problem
I'm curious...can you test what happens if you make it a one-sided test? That
would eliminate local minimums.
if((smspec[j]>smspec[j-1]) || (smspec[j]>smspec[j+1]) && (npk<200))
{
Also...what's the distribution of the snr values for the successful vs
unsuccessful decodes? Maybe there's a better value to be had there.

Joe,
Frequency-sorting has now been committed.
It dawned on me that it is no longer really appropriate to insist that a
decoding candidate correspond to a local maximum in the average spectrum. I
tried this simple change:
$ diff wsprd_exp.c ~/Builds/wsjtx/lib/wsprd/wsprd_exp.c

On my 20m wav files it gives us another 10% over the current wsprd_exp with
subtraction and two-passes, or a whopping 47% improvement over the current
default wsprd:
Default wsprd: 1315 in 163s
wsprd_exp: 1758 in 270s
no peak requirement: 1934 in 1487s
With this change, a case that yields 16 decodes from the current wsprd_exp now
yields 19 decodes from one .wav file!
It is dog-slow as it stands. But I’m sure that there are things that we can do
to speed it up significantly. This might be a good application for openmpi, no?

On Mac we don't have a C++ OpenMP (OpenMPI is a different tool for message passing) implementation available. To get the current Fortran OpenMP code working on Mac we have had to take some liberties with mixing gfortran OpenMP code with C & C++ code compiled with Apple clang & clang++ which have no OpenMP support. We must use Apple clang++ on Mac since that is the only fully supported C++ compiler with Qt on that platform. I would strongly suggest using threading probably supported by the Qt framework if we wish to obtain parallelism in our C++ code. > > Steve k9an > 73 Bill G4WJS. -- Monitor 25 network devices or servers for free with OpManager!

Please be aware that the best email reflectors for such "wish list" suggestions for any of the WSJT programs are wsjtgr...@yahoogroups.com or wsjt-devel@lists.sourceforge.net. I have been reading the wsjt_ss_is...@yahoogroups.com list, however, so your wish to see ISCAT as a part of WSJT-X has been duly noted. You should know that for a long time the following sentence has appeared in the WSJT Home Page in a short section titled WSJT-X: http://www.physics.princeton.edu/pulsar/K1JT/index.html "Plans call for the eventual inclusion of other popular modes now supported in WSJT." On the more detailed web page devoted to WSJT-X, you'll find the following: http://www.physics.princeton.edu/pulsar/K1JT/wsjtx.html "*Future plans*" "Future versions of WSJT-X will include other popular modes from WSJT and its sister programs, starting with WSPR and JT4." WSPR and JT4 are already implemented in WSJT-X v1.6.0, our code-development branch. Many users are building this version of the program for themselves, using tools we developed that make this task reasonably painless for non-programmers. These users have been a great help to us in debugging and otherwise improving the program. We have not yet started work toward implementing any of the WSJT "fast modes" (JTMS, FSK441, ISCAT, JT6M) in WSJT-X. As a group these modes have a major distinction from any of the slow modes: the protocols do not include forward error correction. Decoding strategy is rather different, and more dependence is placed on operator decisions and discretion. I have not even thought about what JTAlert (or other cooperating programs) might do with decodes from the fast modes. Logging should be OK, though. Fair warning: at various times we have thought it might be better to support the WSJT fast modes in a separate program, distinct from WSJT-X. Maybe yes, maybe no; maybe even "try it and see".

Under Windows and Ubuntu Linux I see no such bad behavior. All WSJT modes run as expected, over long times and with no evident memory leaks. Perhaps you can make some tests to isolate the code leading to a memory leak on your system.
