Current Status


DMCS Remote Service Request Functions
dmcs_async_rsrX RSR with an X argument handler where X = {0,1,2,3,4}
dmcs_async_rsrN RSR with a handler taking a variable size buffer
DMCS Remote Memory Manipulation Functions
dmcs_malloc allocate memory on a remote processor
dmcs_free free memory on a remote processor
dmcs_put copy a data buffer to a remote processor
dmcs_put_op copy a data buffer to a remote processor; the remote processor then returns with a dmcs_async_rsr1
dmcs_get retreive a data buffer from a remote processor
dmcs_get_op requests a dmcs_put_op be executed on a remote processor
DMCS Environmental Functions
dmcs_init & shutdown initialize and shutdown DMCS
dmcs_my_proc the relative process ID of the calling process
dmcs_num_procs the number of running processes
dmcs_register_rsrX_handlers registers rsrX type handlers where X = {0,1,2,3,4,N}
