| - | ===== Changes in the release sep91.1 ===== | ||
| - | |||
| - | ------------------------------ | ||
| - | |||
| - | * 1- libraries the library libsep.a has been split into a library libsep.a ( should be renamed libcube.a , but for backward compatibility we kept libsep.a ) which contains only the functions which handle header and data cubes and a second library libmath.a which contains all math functions ( complex function and ffts ). libmath.a also contains some functions from libpete.a .The libraries libpete.a and libpaul.a have been removed from this release , a small part of their contents ( ftlib1.f utelib.r ) has been moved to libmath.a and libutil.a .The libray libFPSF continues to be a part of this release , since a lot of programs are using it . Now it is portable . | ||
| - | * 2- programs The release sep91.1 contains only a selection of programs ( statisticaly the most used ones ) from the original sep distribution . | ||
| - | * 3- self documentation Self documentation has been written in a man style .An environment variable SEP_DOC_PATH ( MANPATH style ) has been introduced to make the self documentation independent from the fullpath of the sources . the self documentation path is defined at the compile time by a relative path ( see SRC_DIR in the makefiles ). Sep programs look for the name of the root directory of the self documentation path in all directories in the SEP_DOC_PATH variable . | ||
| - | * 4- data format\\ | ||
| - | * 1- add to the each data file the data format description : this information is kept in the header files as the value of a new protected keyword data_format : \\ | ||
| - | * data_format=xdr_float or native_float | ||
| - | * =xdr_long native_long | ||
| - | * =xdr_short native_short | ||
| - | * =xdr_char native_char | ||
| - | * esize=0 data_format=native_char | ||
| - | * esize=4,8 data_format=native_float | ||
| - | * 2- modify sreed to decode xdr data format if necessary according the data_format parameter . \\ | ||
| - | * 3- modify srite to encode xdr data format . This should be the default in order to make encoding automatic and therefore xdr the default data format . \\ | ||
| - | * 4- modify the sep programs that use reed and rite ( or worse read and write ) . I made some statistics about the use of reed and rite , it seems that very few programs use these functions . \\ - running sep programs across the network \\ if the xdr data format is the default for all output data files , running programs across the network will be straightforward . \\ - performance \\ -why encode and decode data when pipes are used . It is possible to avoid this overhead by making sreed and srite use native format if the data file is a pipe , in which case pipes across network won't work ( there is no way to know if the pipe is across the network or not ) . I propose to let the user decide : \\ on the same machine \\ Prog1 < input.h | Prog2 > output.h \\ xdr data format is used for ios in the pipe . It may cost a little . ( I made a small benchmark on a sparc station , it is negligible compared to ios ) ( I wonder if it is a real test , native data format on a sparc station is already ieee ( xdr ) ) . Anyway the , performance of xdr is probably machine dependent . \\ Prog1 data_format=native_float < input.h | Prog2 > output.h \\ the user forces the programs to use native data format for ios in the pipe across the network\\ | ||
| - | * Implementation\\ | ||
| - | * tagstream : to init xdr stream | ||
| - | * sreed : to decode xdr format | ||
| - | * srite : to encode xdr format | ||
| - | * input : to get data_format parameter from input header | ||
| - | * output : to set data_format in output header | ||
| - | * ./ | ||
| - | * ./ | ||
| - | * ./ | ||
| - | * Cabs, | ||
| - | * Clip, | ||
| - | * Conj, | ||
| - | * Spike : have been converted to xdr format . | ||
| - | * Add, | ||
| - | * Dd, | ||
| - | * Disfil : should be completely modified . | ||
| - | * Arcy : converts data from ibm to native format | ||
| - | * Swab : is already a data format conversion program | ||
| - | * Cat, | ||
| - | * In, | ||
| - | * Ls, | ||
| - | * Merge, | ||
| - | * Mv, | ||
| - | * Reverse, | ||
| - | * Rm, | ||
| - | * Pad, | ||
| - | * Cmplx, | ||
| - | * Real, | ||
| - | * Imag, | ||
| - | * Rtoc, | ||
| - | * Window : don't need to know about data format . The programs Pad Cmplx Real Imag Rtoc may not work on machine with words of 8 bytes length ( this will be the case of many sep programs since most of then use 4 as the size of floats ) . | ||
| - | * ./ | ||
| - | |||
| - | * 5- Graphics\\ | ||

| - | ===== Changes in the release sep92.1 ===== | ||
| - | |||

| - | |||
| - | ===== Release 3.0 ===== | ||
| - | |||
| - | Rickmovie \\ Rick Ottolini has provied a new version of X11movie that is truly amazing. Much improved controls and display options are available. \\ New and improved platform support SEP has acquired two new platforms in the past year an SGI Power Challenge and a number of PCs running Linux. Thanks to Martin Karrenbach, Paul Hargrove, and Stew Levin SEP as added support for: | ||
| - | |||
| - | * SGI64 - for the SGI Power Challenge running IRIX 6.1 and above | ||
| - | * SGI32 - for the SGI Power Challenge 6.1+, 32 bit version that allows libraries and object files compiled on 32 bit SGI machines to be linked with SEPLIB | ||
| - | * LINUX - for LINUX 1.5.3 and above, tested exclusively on 586 PCs | ||
| - | |||
| - | In addition, thanks to Mickael Kern the DecAlpha (ALPHA) platform has been further debugged. | ||

| - | |||
| - | Chevron compression software Chevron has allowed SEP to distribute its decompression library which can compress to ratios of 50-100 with minimal data loss. The current distribution provides the decompression library for SUN4, SGI, SGI32, and HP700 platforms. | ||
