    pFPC

    From a newsletter announcement:

    ---- QUOTE ----
    Dear FPC user,

    I wanted to let you know that a new version of FPC, called pFPC, is now available at http://users.ices.utexas.edu/~burtscher/research/pFPC/
    pFPC is designed for use in a shared-memory parallel environment but can also be run sequentially. It is faster on x86-based machines and simpler than the previous version.

    pFPC is described here: http://users.ices.utexas.edu/~burtsc...cts.html#DCC09

    A new and more detailed description of FPC is here:
    http://users.ices.utexas.edu/~burtsc...acts.html#TC09

    Kind regards,
    Martin

    PS: Please drop me a line if you are or have been using FPC for something interesting (I may place a link to your work on the FPC web page).

    Didn't work for me

    Code:
    pfpc.exe 11 2 8 < obs_info.trace.fpc > out.pfpc
    pFPC v1.0 written by Martin Burtscher
    (c) The University of Texas at Austin
    Produces a 14kb file (far too small?!?)

    Code:
    pfpc.exe 11 2 8 < out.pfpc > test.fpc
    pFPC v1.0 written by Martin Burtscher
    (c) The University of Texas at Austin
    Produces a 4kb file. Not the 8mb original.

    Could you add a usage to the program if I start it without parameters or -h? Parameter description there would be welcome too.
    Also the description of the website for the level + chunk parameter is absolutely not enough. What's the affect from where up to what is the range?

    SPDP floating-point compressor is released.
    http://cs.txstate.edu/~burtscher/res...PDPcompressor/

    My compile created archives of 793 bytes in size - does your compile work?
    example input files are here: http://cs.txstate.edu/~burtscher/res...sets/FPsingle/
    those examples need to be uncompressed first which also doesn't seem to work.

    Yes (tested on num_plasma.sp.spdp), "as always" the problem is to handle the input/output stream in binary mode instead of text mode.

    Compare: (<)SPDP_10.c (7722 bytes)
    with: (>)SPDP_10_bio.c (7819 bytes)

    > setmode(fileno(stdout), O_BINARY);
