Add the otf library. Modification of the interface console to take care

of 
otf traces. Modification of the parsers to have the otf one, beginning 
of it (containers are printed), adding a new statistics on counters.

New macros in the main_ressource.hpp for the ViTE version (major, minor, 
and a string one).

Modification of the configure script to handle all the changes, you 
should have to restart the script to be able to compile (make distclean 
&& ./configure && make should work).

src/general/otf/ChangeLog

+1.0
+	- initial version
+	
+1.1.1
+	- OTF_Reader now considers the return values of the handlers
+	- added OTF_VERBOSE, OTF_DEBUG macro for error treatment
+	- introduced 'UnknownRecord' handler which allows to catch
+	  unknown record types
+
+1.1.2
+	- inverted return value of call-back handlers: 
+	  '0' is non-error, '!= 0' is regarded as an error, now!
+	  (this makes OTF conform with the VTF3 scheme.)
+
+1.1.3
+	- fixed a minor bug in otfaux
+
+1.1.4
+	- fixed a bug in OTF_Reader which might have caused the very first 
+	  time stamp of a trace to be not properly sorted
+	- introduced '--snapshots' and '--statistics' switches to do only 
+	  snapshots or statistics. for statistics a selective mode is allowed
+	  which regards only some streams. By this means statistics can be created
+	  in parallel by calling otfaux multiple times.
+
+1.1.5
+	- have UnknownRecord report handle incomplete records or additional bytes at 
+	the end of a file.
+
+1.2
+	- introduce transparent zlib compression
+
+1.2.1
+	- added progress functions using read bytes instead of timestamps
+
+1.2.2
+	- important bugfix: definitionstream 0 was ignored since version 1.2
+
+1.2.3
+	- bugfix: provided copy handlers returned wrong value
+
+1.2.4
+	- bugfix: zlib compression bug, wrong sanity check fixed
+
+1.2.5
+	- bugfix: correctly handle process groups with more than 1000 entries
+
+1.2.6
+	- support shared libraries
+1.2.7
+	- added progress functions to OTF_RStream
+	- added a progress counter to otfmerge
+1.2.8
+	- allow suffix '.dylib' for zlib library file (from Mac OS X)
+	- removed configure warning
+
+1.2.9
+	- changeable zlevel
+	- changeable zbuffersize
+
+1.2.10
+	- bugfix: otfmerge does no longer accept traces with local streams
+
+1.2.11
+	- changed OTF_RETURN*( 0=success, !0 = error )
+	- added these macros to all internal functions and tools for better
+	  consistency
+	- fixed various memoryleaks in otf and otfmerge
+	- added otfconfig to tools. otfconfig shows installationparameters
+	  important for developers
+	- updated documentation
+	
+1.2.12
+	- removed intel compiler warnings in otfmerge
+	- removed debug output
+	- fixed 64bit issue
+
+1.2.13
+	- removed intel compiler warnings
+	- changed OTF_FILETYPE_*-macros
+	- fixed issues with OTF_getFilename()
+
+1.2.14
+	- do not linke with '-lz' if '--with-zlibsymbols' was specified
+	- added zlib include line to otflib/Makefile.am
+
+1.2.15
+	- 3 new records introduced (NOTE: these are experimental):
+	- DefFile
+	  - DefFileGroup
+	  - FileOperation
+1.2.16
+	- fixed a problem with comments in otfmerge
+	- 2 new records introduced (NOTE: these are experimental):
+	  - OpenFileSnapshot
+	  - FileOperationSummary
+1.2.17
+	- bugfixed parser (wrong treatment of unknown records)
+	- added FileGroupOperationSummary record
+	- changed FileOperation-, OpenFileSnapshot- and FileOperationSummary- record
+	  NOTE: these records are still experimental
+	- included file operation records into all tools
+	  NOTE: some parameters were added/changed
+	- the byte-parameter in the FileOperation record does now contain the
+	  new position in the file file after the seek operation
+	- bugfixed otfmerge
+
+1.2.18
+	- added fwrite check for writting less bytes than expected
+	- re-write of otfdump. Now, it uses OTF read lib instead of plain scanf. 
+	  It produces nicer output and numbers records in read order.
+
+1.2.19
+	- finished otfdump
+	- removed debug output in OTF_Reader.c
+	- re-introduced DefVersion record as read only
+
+1.2.20
+	- added own inttypes definitions in case there is no on the platform 
+	  (necessary on NEC SX6)
+
+1.2.21
+	- fixed "--with-zlib-symbols"-bug
+
+1.2.22
+	- fixed inttypes/stdint bug
+
+1.2.23
+	- removed libtool from autoconf to make configure much faster, 
+	  libtool was not used by automake anyhow
+	- removed some autoconf-generated files from CVS, 
+	  you might need to re-run 'sh bootstrap' yourself
+
+1.2.24
+	- minor change in otf[de|un]compress
+	- strictly avoid writing of unsorted time stamps. Now, there will be an
+	  error message and the corresponding buffer/stream will be disabled for
+	  further writing. The write routines provide an invlaid return code but
+	  currently there is no way to "repair" the buffer/stream after an unsorted
+	  time stamp has been issued.
+
+1.3
+	- integrated libtool for shared and static linkage to otf
+	- removed the possibility to include zlib symbols into otf
+	- fixed warning which appeared when not using zlib
+	- added python bindings to the otf library
+
+1.3.1
+	- if an fopen() call fails an error is now printed out every time
+	- OTF_READ_ERROR was introduced as an error return value for all
+	  OTF_Reader_readXXX and OTF_RStream_readXXX functions. So (uint64_t)-1 is
+	  now a reserved value, thus cannot be used as record limit.
+	  The record limit always has to be smaller than or equal to
+	  OTF_READ_MAXRECORDS.
+	- fixed issue in otfmerge, when using many streams
+
+1.3.2
+	- added small functions to convert various variable types to common 
+	  counter type uint64_t. By this means, other types can be transported 
+	  as uint64_t and re-casted during reading.
+	  This requires type information as additional counter property flags!
+
+1.3.3
+	- fixed configure bug when searching for zlib on mac
+	- fixed bug in otfmerge, where the parameter "-n 0" caused an error
+	- added macros for specifing the data type of the counter
+	  (OTF_COUNTER_VARTYPE_*)
+	- fixed otfconfig help text
+	- fixed bugs when using make dist
+	- python bindings disabled by default
+	- fixed configure bug, when using python bindings
+	- updated python bindings to support user defined counters
+
+1.3.4
+	- bug fix in otfmerge: missing handling of DefCollectiveOperation
+	- bugfix in the documentation: overview.eps was broken
+
+1.3.5
+	- added doxygen html documentation (docu/doxygen/html/index.html)
+	- fixed issue, where newlines were forbidden in def, stats and snaps
+	- added missing const to OTF_WStream_writeDefProcessGroup()
+
+1.3.6
+	- OTF_{Keywords.h,Parse.h,Platform.h} will no longer be installed
+	- added a compile time assert making sure the correct sizes of the
+	  integer types ([u]int*_T)
+	- OTF is now Windows Visual Studio compatible
+
+1.3.7
+	- added example for using OTF_MasterControl to the doxygen documentation
+	- general improvement of the documentation
+	- improved autoconf's m4 scripts for cross buildings
+
+1.3.8
+	- generate OTF_inttypes.h during configuring which provides
+	  the integer types like int64_t, int8_t,...
+	- shared OTF library will be linked with zlib, thus additionally
+	  linking with zlib is not necessary
+	- bugfix in otf2vtf: correctly handle function leave records with id 0
+
+1.3.9
+	- fixed a portability bug: use own implementation of function
+	  'strdup()'
+	- install a symbolic link 'otfdecompress' which is a synonym for
+	  'otfcompress -d'
+
+1.3.10
+	- added configure option '--[enable|disable]-binaries' to control
+	  building of binaries (useful for multi-lib installations)
+
+1.4
+	- added tool 'otfprofile' which can be used to generate CSV/Latex-
+	  summaries about functions and P2P-messages of a trace
+	- build/install tool 'otfdump' by default
+	- install documentation
+
+1.4.1
+	- bugfix: removed included system headers inside 'extern "C" {}'
+	- bugfix: added configure check for functions 'fseeko()' and 'ftello()'
+	  (these functions are not available on NEC SX platforms)
+	- bugfix in otfprofile: fixed infinite loop while drawing the
+	  statistics for "top 50 of counters"
+
+1.5
+	- added file operation begin/end records
+	- added file operation types OTF_FILEOP_UNLINK, OTF_FILEOP_RENAME,
+	  and OTF_FILEOP_OTHER
+	- use part of fileop for I/O flags (e.g. async, coll.)
+	- added collective operation begin/end records
+	- added remote memory access (RMA) operation records
+	- added marker records
+
+1.5.1dolphin
+	- corrected package preparation for libtool
+	- build shared OTF library by default
+	- added version information to shared OTF library
+
+1.5.2dolphin
+	- adapted python bindings to the current API (related to new record
+	  types)
+	- if possible, otfprofile creates a PS-file
+	- fixed VPATH issue, when using python bindings
+	- fixed infinite recursion in python wrappers
+	  pyOTF_COUNTER_VARTYPE_ISSIGNED and pyOTF_COUNTER_VARTYPE_ISUNSIGNED
+
+1.6stingray
+	- added tool 'otfshrink' which can be used to reduce a trace to
+	  specified processes
+	- introduced an error variable (otf_errno, otf_strerr) that indicates
+	  whether an error occurred or not
+	- fixed build dependencies of otfprofile
+	- added file operation types OTF_FILEOP_DUP, OTF_FILEOP_SYNC,
+	  OTF_FILEOP_LOCK, and OTF_FILEOP_UNLOCK
+	- changed datatype for sent/received data volume of collective
+	  operation begin/end records from 'uint32_t' to 'uint64_t'
+	- replaced usage of PATH_MAX by VT_PATH_MAX to avoid compile errors

src/general/otf/README

+ Open Trace Format (OTF)
+
+Detailed program analysis of massively parallel programs requires the recording of event based performance data during run-time and its visualisation with appropriate software tools like the Vampir framework.
+
+The specification of a convenient and powerful trace file format has to fulfill a large number of requirements. It must allow an efficient collection of the event based performance data on a parallel program environment. On the other hand it has to provide a very fast and convenient access to the large amount of performance data and the corresponding event definitions by the analysis software tools.
+
+To improve scalability for very large and massively parallel traces the Open Trace Format (OTF) has been developed at ZIH as a successor format to the Vampir Trace Format (VTF3).
+
+The Open Trace Format makes use of a portable ASCII encoding. It distributes single traces to multiple so called streams with one or more files each. Merging of records from multiple files is done transparently by the OTF library. The number of possible streams is not limited by the number of available file handles.
+
+The provided read/write library should be used as a convenient interface for third party software. The library supports efficient parallel and distributed access to trace data and offers selective reading access regarding arbitrary time intervals, process selection and record types.
+Optional auxiliary information can assist this selective access.
+
+The software package contains additional tools for trace date conversion or preparation.
+More information can be found in the provided documentation.
+
+OTF version is available as open source software under the BSD license, see 'COPYING'. The software comes as a source code package. It can be installed by using autoconf procedures, see 'INSTALL'.

src/general/otf/TODO

+- re-design OTF's error/success return values for handlers and functions
+
+- ideas for future development
+	- add memory allocation/deallocation record types, how?
+	- have more semantics
+	- have less semantics
+	- add general purpose record types like (type/owner,key,value) with no semantics,
+		-- can be used freely, ignored if unknown, 
+		-- key/value are either uint64_t, array of uint64_t or text
+
+- add record to write wall clock time or epoch or year:month:day:hour:minute:second
+	with this, VT can record time at start and end of trace (request by Robert Henschel)
+
+- create a (graphical) tool for changing definition records:
+  - grouping functions
+  - ...
+
+- solve the problem that when only reading statistic records one cannot
+  determine the begin and end of a process !!!!!
+  You might introduce a new record for this. ( maybe like begin/endprocess
+  for events? )
+  You could also write a statistics comment record when the first event appears,
+  (in otfaux)
+
+- add new statistics record type that gives the caller-callee relation 
+	- only write this at the end of a trace run
+
+- use asynchronous write (aio_write) and maybe even read for performance 

src/general/otf/VERSION

+# This is the VERSION file for OTF, describing the precise version of OTF in
+# this distribution. The various components of the version number below are
+# combined to form a single version number string.
+
+# major, minor, and sub are generally combined in the form
+# <major>.<minor>.<sub>. If sub is zero, then it is omitted.
+
+major=1
+minor=6
+sub=0
+
+# string is used for alpha, beta, or release tags. If it is non-empty, it will
+# be appended to the version number.
+#
+# history of release tags:
+# 0.2.*        octopussy
+# 0.3.*-1.1.*  starfish
+# 1.2.*        pufferfish

+
+# library is used for the library versioning. These three numbers will be added
+# to the name of the library (e.g. libotf.so.1.2.3).
+# The meaning of these numbers is as follows (from left to right):
+#
+#   current            The number of the current API exported by the library.
+#                      That must be incremented, if the API has changed.
+#   revision           The implementation number of the most recent API
+#                      exported by the library. A value of '0' means that this
+#                      is the first implementation of the API.
+#                      If any of the source for the library has changed,
+#                      revision must be incremented.
+#   age                The number of previous additional APIs supported by the
+#                      library. If age is '2', the library can be linked into
+#                      executables built with a release of the library that
+#                      exported the current API number (current), or any of
+#                      the preceding two APIs.
+#                      If the new API is backward-compatible with the preceding
+#                      release, age must be incremented. Otherwise, reset age
