Hi Naveen,
The OpenSHMEM (1.3) specification document (page 58) states that:
"The pWrk argument must have the same data type as dest. In C/C++, this contains
max(nreduce/2 + 1, SHMEM_REDUCE_MIN_WRKDATA_SIZE) elements."
http://www.openshmem.org/site/sites/default/site_files/OpenSHMEM-1.3.pdf
The osu_oshm_reduce benchmark in OMB is following the OpenSHMEM standard. Further, the collective benchmarks in OpenSHMEM report number of elements instead of bytes as max_msg_size is 4M that corresponds to 1M float elements.
Please let us know if there is any other issue.
Thanks
Jahanzeb
