List of revisions

• (jayesh) 1) Corrected macro definition indicating inclusion of a header file - WAS - #define *CONF_H - IS NOW -#define *CONF_H_INCLUDED 2) Creating ch3usockconf.h
• (thakur) added Fred Webb's TotalView related comments
• (thakur) added Fred Webb's Totalview-related updates
• (chan) added MPE logging instrmentation for PVFS_sys_read() and PVFS_sys_write().
• (chan) Added MPE logging instrumentation for open().
• (gropp) Added a new MPID function
• (gropp) Added a test for orphaned executables
• (gropp) Added const to constant strings
• (chan) Added global variables for MPE logging instrumentation
• (rross) added include of mpitypedefs.h to help with define of int64_t on windows.
• (gropp) Added runhalo and options for MPI RMA optimizations in the halo exchange tests
• (mercierg) Added test for ext_procs existence for network polling
• (gropp) Added test for partial comm when building a cartesian communicator
• (gropp) Added the start of PMI v2 in simple2
• (rross) blocks).
• (rross) can now successfully build a binary using these calls (which quickly crashes :)).
• (rross) committing changes from ROMIO side.
• (rross) contents_support.c no longer belongs here.
• (rross) fine tuning and performance optimization to make dataloops easier to usein ROMIO and to reduce overhead of certain operations (e.g. counting contigblocks).
• (rross) fix for bug noticed by jayesh.
• (gropp) Fix for struct ifconf with POSIX selected on OSX
• (gropp) Fix to Comm_copy for size < old size
• (gropp) Fixed formatting in file
• (thakur) fixed typo
• (rross) fixes to help with int64_t on windows.
• (thakur) Fred Webb's changes for Totalview
• (rross) handle shared library objects too.
• (rross) in ROMIO and to reduce overhead of certain operations (e.g. counting contigblocks).
• (rross) into segment_ops.c instead.
• (rross) minor sync with ROMIO version.
• (rross) Moved contents_support.c to romio_contents_support.c (also removing versionover on MPICH2 side). Added MPIO_Datatype_init_dataloop() function. Misc. cleanup.
• (rross) moving around contents support code.
• (buntinas) nemesis blocking: adding communication thread. ping-pong works
• (buntinas) nemesis blocking: more debugging
• (buntinas) nemesis: in requests, replaced ch.iov_offset with dev.iov_offset
• (rross) over on MPICH2 side). Added MPIO_Datatype_init_dataloop() function. Misc. cleanup.
• (rross) pack/unpack operations are now in segment_ops.c, and bugs have been fixed inthem.
• (chan) removed the old MPE logging calls with hardwired eventIDs. Replaced them with MPE logging calls that are compatible with MPE2. The profiled IO calls are open/close/read/write/lseek. The instrumentation can be turned on by -DADIOI_MPE_LOGGING.
• (chan) Removed the old MPE logging calls with hardwired eventIDs. Replaced with MPE logging calls that are compatible to MPE2. The instrumentation can be turned on by -DADIOI_MPE_LOGGING.
• (rross) romio-specific dataloop processing ops.
• (rross) should fix build problems on solaris.
• (rross) still working on basics before integration.
• (rross) them.
• (rross) to determine if types are N contiguous. this facility is exported now.pack/unpack operations are now in segment_ops.c, and bugs have been fixed inthem.
• (rross) typesize_support now calculates true_lb and true_ub, so that we can use theseto determine if types are N contiguous. this facility is exported now.pack/unpack operations are now in segment_ops.c, and bugs have been fixed inthem.
• (mercierg) Typos corrected
• (chan) updated cpilog_pack.c with example to do source file tracing using __func__ and __LINE__ and added Darius's sub-micro timer support with USEC_TIMING.
• (rross) updates, including moving pack/unpack functionality out of mpid_segment.c andinto segment_ops.c instead.
• (rross) use PMPI instead of MPI functions. (why is this necessary?)
