Subject: sha512crypt-opencl format fails in xeon phi coprocesor
I'm trying to use the sha512crypt-opencl kernel with a xeon phi coprocesor.
When using the host device, it works smoothly, but using the MIC
(coprocesor) it fails to build the kernel cryptsha512_kernel_DEFAULT.cl.
This is the output:
[john-1.7.9-jumbo-7]$ LWS=32 GWS=5120 STEP=256 $J/run/john --test
--format=sha512crypt-opencl --device=1
OpenCL platform 0: Intel(R) OpenCL, 2 device(s).
Using device 1: Intel(R) Many Integrated Core Acceleration Card
Building the kernel ($JOHN/cryptsha512_kernel_DEFAULT.cl), this could take a
while
1 warning generated.
