My sketch is large. Global variable byte count is exceed by 13%. But I have very few GVs. program byte count is 48% of maximum.
How does the compile determine Global vairable byte count? What suggestions is there to alleviate this difficulty?

There you go. All your UNO's memory consumed in one variable.
Show us your code. Use [ code ] tags. (The button looks like </> in the "reply" editor, not "quick-reply".)
Got large unchanging arrays? Lot of Serial.print statements of unchanging messages? Both can be moved to flash to free up SRAM.
Post (Attach) your code, other suggestions can be made. Worse case, move to a 1284P processor with 128K flash, 16K SRAM, 32 IO. I offer boards in several form factors, such as this Uno-like board, see my website for others:

I was trusting that another board (Mega?)with greater SRAM space would be the fix. I will visit your website...
