- Remove hdp and ipc pointers from BlockHandle, align RO stats with RO contexts - Add run commands for `rocshmem_g` and `rocshmem_p` API tests in driver.sh - Allocate rocshmem API return buffers based on number of device contexts. - Associate status flag address with blocking calls and remove threadId dependency - Associated the status flag address with each blocking call request to notify the GPU thread. - Removed dependency on threadId for determining the appropriate status flag index. - Move status flag buffer allocation to backend. - Initialize allocated memeory to zero
