Error running latter

[zhqingg]

Hi @johnjmar
Can you let me know if you've run into error with Memory/Latter
Build the binaries of stream and lat_mem_rd as the instruction. When executed latter.sh, the process stuck in this line “lat_mem_rd 5i3000 128 0 0 72”.
analysis the usage of lat_men_rd

Usage: ./lat_mem_rd [-P <parallelism>] [-W <warmup>] [-N <repetitions>] [-t] len [stride...]

So the _ARGS for lat_men_rd is wrong I think
So we should Modify some part

And the usage of lat_mem_rd do not support to choose chip.maybe,the source code need to modify again.

@zhqingg you're correct. This is indeed a bug.
For the time being would you please replace function LTlat_mem_rd in the original script with the one below in the included file?
latter.tmp.txt

Also, you are correct in that the the ARGs should be changed to lat_mem_rd ${LT_BUFSIZE} ${LT_STRIDESIZE}

FYI, the owner of the benchmark in no longer in the company and the script may require more work.
