Subject: [parsec-users] Blackscholes TBB Version: err_chk uses wrong tolerance
as I noticed here
The error treshold for "err_chk" in blackscholes has been changed from "1e-5" to "1e-4" in Parsec 2 or 2.1.
Yet the TBB version of the blackscholes benchmark still uses the old treshold which leads to errors on large datasets using "float".
In the attachment is a patch that fixes the tolerance, bringing it in line with the other blackscholes variants.
