* add "register" function to mca_base_component_t * converted coll:basic and paffinity:linux and paffinity:solaris to use this function * we'll convert the rest over time (I'll file a ticket once all this is committed) * add 32 bytes of "reserved" space to the end of mca_base_component_t and mca_base_component_data_2_0_0_t to make future upgrades [slightly] easier * new mca_base_component_t size: 196 bytes * new mca_base_component_data_2_0_0_t size: 36 bytes * MCA base version bumped to v2.0 * '''We now refuse to load components that are not MCA v2.0.x''' * all MCA frameworks versions bumped to v2.0 * be a little more explicit about version numbers in the MCA base * add big comment in mca.h about versioning philosophy This commit was SVN r19073.

* Processor affinity for Linux.
|
|
*
|
|
* Linux sucks. There are at least 3 different ways that
|
|
* sched_setaffinity is implemented.
|
|
*
|
|
* Fortunately we have an independent project called Portable Linux
|
|
* Processor Affinity (PLPA) which allows us to do processor affinity
|
|
* without knowing which flavor of afffinity is installed on the
|
|
* system a priori - PLPA does a few probes behind the scenes and
|
|
* utilizes the correct syntax to the correct system call to set
|
|
* or get processor affinity for us.
