Msieve failed to polyselect
 

Since I have updated my drivers, my Msieve ( wich worked before) fail to work with this message

[code]
error (sort_engine.cu:163) a PTX JIT compilation failed
[/code]I use a Geforce 750 Ti (compute capability 5.0).
I tried rollnack the drivers, update my cuda toolkit, , re-update the drivers, to no avail.
Any idea?

Is this on Windows or Linux?
Driver/ CUDA toolkit version?
Msieve version?

I think that cuda got more picky on compute capabilities.
You can try the following patch.

Ouch, the compile times are going to balloon if we have to separately compile for every single compute version out there.
