Information on all weekly change summaries is available.

List of revisions

• (chan) A serial merge of clog2 files whether they are local, or finalized logfiles of individual MPI_COMM_WORLD of a MPI-2 multiple comm_worlds program.
• (gropp) Added a test suggested by Intel
• (chan) Added boolean value to show if the logfile is local or finalized. Added file offset location to the CLOG_CommSet_t's table[] at the end of logfile. Added copy() function for CLOG_Preamble_t, a sync() function which is between a pair of CLOG_Preamble_ts is used by serial clog_join.
• (gropp) added comment about test for -genvlist reported by Intel
• (chan) Added configure template for fixed size integer types.
• (gropp) Added some missing function prototypes
• (chan) Added support for newly added headers, clog_inttypes.h and clog_const.h.
• (chan) Added support of CLOG_BOOL_T and a real-time detection of endianness.
• (chan) Added support of CLOG_int32_t and i32fmt to CLOG_Uuid_t.
• (chan) Added support of boolean variable to indicate if the file is local or finalized.Added support for a file pointer to indicate the location of CLOG_CommSet_t's table[] in the logfile. Added support of Maximum CommWorldSize.
• (chan) Added support of fixed size integer types and their printf format specifers, e.g. CLOG_int32_t and i32fmt, for all integers of all CLOG records written to the file. This removes ambiguity between C and Java integer types.
• (chan) added support of to patch CLOG_BlockData_t with patch_comm(), patch_time() and patch_all() which are needed by clog_repair, clog_join and MPE_Finish_log()...
• (chan) Added support to determine fixed size integer types through macros defined in ../../aclocal_inttypes.m4 and defines the include/clog_inttypes.h for use byboth src/logging, src/wrappers and MPE users....
• (chan) added support to write CLOG_CommSet_t at the end of the logfile and update CLOG_Preamble_t with file offset of CLOG_CommSet_t's location in the logfile. Updated CLOG_Buffer_t's read operation not to read pass CLOG_CommSet_t table and its accompanied error messages.
• (chan) Added the support to new serial programs, clog_join and clog_repair, and their support objects, CLOG_Cache_t, CLOG_Joiner_t.
• (chan) both src/logging, src/wrappers and MPE users....
• (chan) Changed CLOG_Buffer_init() to CLOG_Buffer_init4write() and changed reserved_block_size local function.
• (chan) Contain both a simple and an ptimized version of sort.
• (chan) cosmetic changes.
• (chan) Disabled logging before entering CLOG_CommSet_add_intercomm/interacomm() andenabling logging after exiting. This is done to avoid circular logginghappened some vendor MPI implementation. First detected on Cray X1E's MPIwhere MPI_Init and all MPI-1 communicator function are implemented withMPI functions.
• (rbutler) Empty gdba value in spawns
• (gropp) Fix APPNUM value in Fortran (make sure same behavior as in C)
• (gropp) Fix typo in CS_EXIT
• (chan) fixed install instruction for Cray X1E cross-compilation.
• (chan) Initial deposit of CLOG_Cache_t which is a simplified/serial version of CLOG_Buffer_t. Added machinery of building and manipulation of a binary linked list of CLOG_Cache_t in support sorting(in time-order of CLOG record), and support of a simple output(read) API of CLOG record from clog2 file. The API is similar to java's Iterator interface. Added read, write and readwrite support of clog2 file.
• (chan) Initial deposit of a CLOG2 repair program. Currently this added the missing CLOG_CommSet_t's table[] for the local logfile.
• (chan) Initial deposit of a serial version of CLOG_Merger_t. CLOG_Joiner_t is built based on CLOG_Cache_t in support sorting in time order using a binary linked list.Contain both a simple and an ptimized version of sort.
• (chan) Initial deposit of autoconf macros that looks for C99 intXX_t headers, macro to define fixed size integer types based on basic integer types, char, short,..., and macro that defines printf format specifiers for the fixed size integer types.
• (chan) Made reserved_block_size() local. Added support to write CLOG_CommSet_t at the end of the merged logfile and updated CLOG_Preamble_t's file offset for CLOG_CommSet_t's table[].
• (gropp) Major update for thread support
• (chan) minor changes to accompany changes in CLOG_Buffer_t and CLOG_Merger_t APIs.
• (robl) missed two spots in the "void*" to "void *" switch
• (chan) Modified configure title.
• (buntinas) nemesis lmt: moved shm lmt flags into separate cachelines
• (buntinas) nemesis: added atomics for itanium 2
• (buntinas) nemesis: fixed lmt compile errors with -O3 and --enable-fast
• (buntinas) nemesis: lmt added atomics for itanium 2
• (buntinas) nemesis: lmt fixed signedness warnings
• (rbutler) Print better err msg when no mpd present.
• (lusk) Removed obsolete -kx optionAdded discussion of MPD_PORT_RANGE environment variable
• (chan) Removed the unused AC_CHECK_SIZEOF of various integer types and void*. Added proper configure check of endianness and its cross-compilation support.
• (chan) Rewritten the print program based on the output/read iteration API of CLOG record using CLOG_Cache_t. The provides a better interface for others to process CLOG2 file.
• (chan) Split clog_const.h into clog_mem.h(memory ops) and clog_const.h.
• (chan) Standardized the operations of CLOG_CommSet_t and CLOG_CommIDs_t to be used by parallel merge of MPE_Finish_log(), and the serial merge in clog_join. Added read/write + byteswap/print APIs of CLOG_CommSet_t.
• (chan) Sync the jar files with the updated source.
• (chan) Update version ID, 2.42/2.43, and their descriptions.
• (chan) Updated version ID to 2.42 then 2.43 and theirs corresponding descriptions.
• (chan) Used the newly added MaxCommWorldSize to compute the lineID.
