We do, there's known versions that have bugs returning incorrect results or
simply crashes.

Re: [boinc_dev] Bug - BOINC 7.8.4 truncates CUDA driver version number

2018-01-15 Thread David Anderson 
BOINC encodes the driver number into an integer in a way that assumes the minor 
number is < 100.


This is bad, of course - BOINC has no business encoding other peoples' version 
numbers -
but fixing it is not easy.
That's because the plan classes used by projects refer to
driver version numbers using these encoded integers.
If we change the representation of version it might break these projects.

Projects: do you in fact have plan classes that use nvidia driver version?

[boinc_dev] Bug - BOINC 7.8.4 truncates CUDA driver version number

2018-01-13 Thread TarotApprentice 
 The CUDA device driver version number is being truncated.
Background: Nvidia released CUDA driver 384.111 (for Linux) to resolve one of 
the Spectre variants. The minor version number of 111 is being truncated to two 
digits (ie 11). The OpenCL detection seems to get it right though.
