SimGrid (2.95) unstable; urgency=low
+ XBT
+ * Steal some nice code to GNU pth to fix context detection and usage [AL]
+ * Cleanup in the xbt_config API; add configuration callbacks. [MQ]
+ * Cleanup in the initialization API: the unused "defaultlog" is dead. [MQ]
+
MSG
- * Implement MSG_get_msgload [MQ]
+ * Implement MSG_get_msgload [MQ, AL]
SURF
* Bugfix: Allow absolute paths for platform description files [MQ]
-
- GRAS
+ * Bugfix: do free the variables after use. Leads to drastic performance
+ improvement [AL]
+
+ GRAS (new features)
+ * Implement measurement sockets. You can now get the bandwidth between two
+ hosts thanks to AMOK (see below). [MQ]
+ * gras_datadesc_dynar() builds a dynar type descriptor, allowing to send
+ dynar over the network (yeah) [MQ]
+ * Real (even if simplistic) implementation of gras_os_myname() on RL [MQ]
+ * simple/static token-ring example. [Alexandre Colucci and MQ]
+
+ GRAS (bug fixes)
+ * Differentiate the types "char[22]" and "unsigned char[22]" in automatic
+ type parsing. "short" and "long" modifiers were also ignored; other
+ modifier (such as reference level) are still ignored. [MQ]
+ * Embeed the buffer size within the buffer itself on SG. [MQ]
+ That way, send() are atomic and cannot get intermixed anymore (at least
+ the ones which are less than 100k; bigger messages still have the issue)
+ * Array size pushed by the field, not by the field type (or each
+ and every long int will push stuff to the cbps) [MQ]
+ * use select() to sleep since it allows to portably sleep less than one
+ second. [MQ]
+
+ GRAS (minor cleanups)
* <project>.Makefile.local (generated from gras_stub_generator) |MQ]:
- Do clean .o files
- Compile with -g
- * bugfix in automatic type parsing: differentiate the types "char[22]"
- and "unsigned char[22]". "short" and "long" modifiers were also ignored;
- other modifier (such as reference level) are still ignored. [MQ]
- * Real (even if simplistic) implementation of gras_os_myname() on RL [MQ]
+ * Type Callbacks now receive the gras_datadesc_type_t they work on as argument.
+ * type category 'ignored' killed as it was never used and were difficult
+ to transmit.
+ * whether a type can cycle or not is now a flag, leaving room for more
+ flags (as "ignored", if we feel the need one day ;)
+ * Rename raw sockets to measurement sockets since "raw" has another
+ meaning in networking community.
+ AMOK
+ * Advanced Metacomputing Overlay Kit introduction. It is based over GRAS
+ and offers features not belonging to GRAS but that most applications
+ need. One day, it may be a set of plugins loadable at runtime.
+ * New module: bandwidth
+ bandwidth measurement between arbitrary nodes running this module. [MQ]
