[GSLL-devel] Loading Foreign Libraries in MacOSX
by David Hodge 01 Apr '13

01 Apr '13

Hi I am using SBCL on MacOSX and when I try to load the latest GSLL it can't find the foreign libraries for libgslcblas and libgsl. Looking at the source from an earlier version I see that the "lib/"prefix has been omitted from the library names. One possible workaround would be to use "gsl-config --libs" and extract the library directory from that. if you are interested I can supply a patch. cheers

[GSLL-devel] CFFI release 0.11.0
by Liam Healy 03 Mar '13

03 Mar '13

CFFI 0.11.0 was released last week. This includes cffi-libffi, which makes FSBV obsolete. The new versions of Antik and GSLL now use cffi-libffi instead of FSBV. For most users of these systems, this is an internal detail and unimportant. However, for the past 6 months at least, I have been using and updating these versions and not the FSBV version. So, with these branches merged into the master branch, a number of patches and fixes have made there way into the master branch. I expect in the March update to quicklisp, all these changes will be in the new dist. Waiting for CFFI to be finalized blocked a number of projects. One is to split up Antik into different systems instead of making one system that loads everything (grid, physical quantities, etc.). Another is dataflow definitions (and coordination with org-mode) that I am just starting on. In GSLL, I've started to look at the definition of physical constants. I don't know when I'll have time to work on these or when they'll be complete, but I'll update when I have something. Liam

Did you review that list, Akshay? I think I've looked at the webpage that was put up by Mark on Berkeley's site. I think the tensor branch sort of satisfies all of them (except perhaps for the LAPACK bits?). Please though take a look at the code.

Hi Akshay, Thank you for your work and your email. I think a lot of people have had very similar thoughts to yours, and have started down the road meeting the needs of users they've identified. There are a lot of good and partially overlapping ideas within this loosely organized group of people. There was a similar discussion started in the context of common lisp stats (which I'm not a member of) a few months ago. Where I was participating, I cc'ed the antik-devel mailing list; see for example http://lists.common-lisp.net/pipermail/antik-devel/2012q4/000019.html and the archives in general http://lists.common-lisp.net/pipermail/antik-devel/2012q4/thread.html with the subject "numerical lisp". My feeling is that we need to break the desired functions into relatively narrow, compatible libraries. I started Antik as a split out of GSLL to handle "grids" (generalized arrays) to start down that road. It needs to be split up further, because it now includes other things such as calculations with physical dimensions. I've started that further split, but haven't done any work on it recently. I am interested in the work you've done; it's been a while since I looked at Matlisp. At the time, it did not meet my needs, but it seems you have done significant work on it and has a lot of potential to be part of the compatible family of libraries as I've described. I think a good first step is to identify the different areas (for example, generalized arrays as I've indicated, or statistics functions) and canvas the current state of software for features and capabilities. I've added Tamas Papp and Mirko Vukovic onto this email because they've been very active in thinking about these things. Also I've added the Antik and GSLL mailing lists for good measure.

[GSLL-devel] Physics-constants library?
by Mirko Vukovic 26 Feb '13

26 Feb '13

I did not find a library with physics constants on cliki or quicklisp. There is one available from within GSLL, but loading GSLL just for physics constants is an overkill. Are there any other ones? I have one of my own (somewhat incomplete) that works for me, and I can clean it up and push it to quicklisp if nothing meaningful is out there. Mirko

[GSLL-devel] added basic fft to my dataframes
by Mirko Vukovic 14 Jan '13

14 Jan '13

In preparation for experiments that start tomorrow, I added today real-array fft and power spectrum capabilities to my dataframe code. It uses GSLL's fft functions (search for file fft.lisp). The classes, generic functions, and methods are still a bit rough, and will be refined. You can read more about it: https://github.com/mirkov/data-table/blob/master/user/example1/README.org That same directory contains examples-w-fft.lisp that shows the code usage. I annotated the code. The png files show sunspot data and two power spectra. The example shows how I create one data-table with raw data, and then another one with slightly massaged data. I do the fft on the latter one. The example also shows that the current syntax is `functional' vs `declarative'. I explicitly build the second data table, instead of declaring its dependency on the first table. I think that the latter approach is preferable from a user's point of view. But I will refrain from trying to design and implement this declarative approach. I need more real-world experience before trying to do this. I may add windowing capability to the fft code later on. Mirko

[GSLL-devel] Error installing GSLL
by Patrick M. Groulx 02 Jan '13

02 Jan '13

Hi all, I have been trying to install GSLL for the past couple of days on Ubuntu and Debian, both running SBCL, and I keep encountering the same problem. I install Quicklisp without any difficulty but when I attempt to install GSLL I get the output that I have included below. It appears that the error is in static-vectors and the use of the component "CFFI-GROVEL-FILE." I'm not seeing where in the source files that I have the component defined anywhere, so I am at a loss as to what it does. I have included the output of (list-all-packages) at the very bottom in case I am missing something. I'm hoping that someone with a more in-depth understanding of the different components can help me out.

[GSLL-devel] FLAME and possible next library ports using grids
by Liam Healy 08 Dec '12

08 Dec '12

On this and other mailing lists, there have been recent discussions of "numerical lisp" which in one aspect or another has been the vision of many of us, some for many years. My approach is to write libraries I think will form a piece of the overall solution, with the hope that others will join in and write compatible libraries that form another piece. So, I initially wrote GSLL and then split the grid part out into Antik (which has other features I adapted from my personal libraries). The grid functions can use enhancement, but they are usable now for developing library ports. I have thought about and had discussions with others about what would be a good candidate library for the next port. These thoughts have revolved mainly around an FFT library (like fftw) or a linear algebra library (like *lapack) because those are widely used and, since GSL already provides some of that capability, offers a good opportunity to compare features and make a unified interface. Recently, I came across the FLAME linear algebra library (http://z.cs.utexas.edu/wiki/flame.wiki/FrontPage). It is designed with an intriguing modularity concept. I think it would be a good library to port to grid/Antik. Unfortunately, I don't have the time to work on this, but if anyone (particularly someone who needs linear algebra capability like this) wants to take it up, I encourage that and will help as much as I can. A big challenge I foresee in any foreign library interface is the allocation of arrays. If it is a "closed box," it makes it hard to use e.g. static-vectors and therefore the arrays have to be copied back and forth between the foreign side and the CL side. GSL has the advantage that there are functions that allow building GSL arrays out of supplied C arrays, so regular CL arrays can be allocated with a C pointer passed to these functions to wrap them with GSL metadata. I'm not sure many other libraries are that flexible; many (e.g. C++ libraries) consider it a virtue to seal off the raw storage (C arrays) from the user, and force you to go through a foreign interface to do the allocation. Since there are almost no CLs that permit construction of CL arrays using foreign data, copying is the only option left. So, if anyone has thoughts on FLAME or any other library, I'll be happy to contribute my ideas if it will help. Liam
