By "vendor" I meant graphics card vendors, not cluster or HPC vendors. 
My interest in this sort of diagnostic arose in relation to an
inexpensive graphics card bought at Newegg.  I was asking here
specifically because it seemed likely that HPC vendors _would_ have
the sort of GPU diagnostic I was seeking, and might be willing to share
it.  (As opposed to the tool Joe referred to, which seems not to be
generally available.)
