1. Introduces a flag for the type of buffer that now allows a user to either have a fully described or a completely non-described buffer. In the latter case, no data type descriptions are included in the buffer. This obviously limits what we can do for debugging purposes, but the intent here was to provide an optimized communications capability for those wanting it.
Note that individual buffers can be designated for either type using the orte_dss.set_buffer_type command. In other words, the buffer type can be set dynamically - it isn't a configuration setting at all. The type will default to fully described. A buffer MUST be empty to set its type - this is checked by the set_buffer_type command, and you will receive an error if you violate that rule.
IMPORTANT NOTE: ORTE 1.x actually will NOT work with non-described buffers. This capability should therefore NOT be used until we tell you it is okay. For now, it is here simply so we can begin bringing over parts of ORTE 2.0. The problem is that ORTE 1.x depends upon the transmission of non-hard-cast data types such as size_t. These "soft" types currently utilize a "peek" function to see their actual type in the buffer - obviously, without description, the system has no idea how to unpack these "soft" types. We will deal with this later - for now, please don't use the non-described buffer option.
2. Introduces the orte_std_cntr_t type. This will become the replacement for the size_t's used throughout ORTE 1.x. At the moment, it is actually typedef'd to size_t for backward compatibility.
3. Introduces the orte_dss.arith API that supports arbitrary arithmetic functions on numeric data types. Calling the function with any other data type will generate an error.
This commit was SVN r11075.
- move files out of toplevel include/ and etc/, moving it into the
sub-projects
- rather than including config headers with <project>/include,
have them as <project>
- require all headers to be included with a project prefix, with
the exception of the config headers ({opal,orte,ompi}_config.h
mpi.h, and mpif.h)
This commit was SVN r8985.
