[PIERRE GIVE THE PATH] + It is now possible to build platforms with specific routing + mechanism (Full/Dijkstra/DijkstraCache/Floyd) and to easily + connect several platforms together. We will try to provide soon + set of realistic platforms exploiting these properties (have a + look at examples/platforms/ for the moment). + * Add a new routing scheme (rule-based) using regular expressions. It + enables to have an extremely low memory footprint when the + underlying routing is simple and can be compactly described. You + need to have libpcre4-dev (perl regular expressions) installed if + you want to use this routing scheme. + * Revive the cluster TAG and allow to easily and efficiently (both in + term of memory and speed) connect clusters together. Have a look + at teshsuite/simdag/platforms/ to see how this can be done. With + this tag, you can create clusters with thousands of tasks at no + cost (have a look at examples/platforms/). + * Add new callbacks to the CPU & netwok models to create resources no need to pass through the parser callbacks to do so. - * add new function to create routes table via the routing model - * add generic functions in the public interface - that allows the user to call SURF 'create_resource' methods from a lua script. - SIMIX : - * New function: SIMIX_process_set_function() - called by MSG_set_function - SimDag + * Add new function to create routes table via the routing model + * Add generic functions in the public interface that allows the user to + call SURF 'create_resource' methods from a lua script. + * Add a new model (enabled through command line --cfg=network/model:SMPI) + that uses a piecewise linear approximation to produce better + results when exchanging small messages. + * Add a new parameter to handle correctly full duplex link and account + for interferences between uplink and downlink communications + (activate with --cfg=fullduplex:1). + + SIMIX + * New function: SIMIX_process_set_function() called by MSG_set_function + * Change the underlying waiting queue in semaphores so that a process + can wait on several of them simultaneously (as in waitany). + * Fix the way to handle tokens in semaphores so that all access patterns + work: {acquire, acquire_timeout, waitany} / {release, release_forever}. + + SIMDAG + * Fix a bug in the management of tasks of size 0 in the surf network + models.
