OpenCL setup problem

[Tommi_T_]

Hi

I've installed latest drivers for mic and opencl-1.2-3.0.67279 but even simplest openCL test program (capsbasic) does not work, it just hangs when it tries to open device. I'm out of ideas what to try next.

 strace  ./capsbasic Intel
....

open("/dev/mic/scif", O_RDWR)           = 7
fcntl(7, F_SETFD, FD_CLOEXEC)           = 0
ioctl(7, 0xc0087303, 0x7fff5a2bda20)    = 0
futex(0x7ff8888139d0, FUTEX_WAIT, 9749, NULL) = 0
close(6)                                = 0
ioctl(5, 0xc0087303, 0x7fff5a2bdae0)    = -1 ECONNREFUSED (Connection refused)
nanosleep({0, 10000000}, NULL)          = 0
ioctl(5, 0xc0087303, 0x7fff5a2bdae0)    = -1 ECONNREFUSED (Connection refused)
nanosleep({0, 20000000}, NULL)          = 0

I don't quite know what's going wrong in your case, but I remember seeing a thread on the forums with a similar error message . http://software.intel.com/en-us/forums/topic/386577

According to this thread, the developer used a customized user management for the coprocessors and hence was missing the `micuser` during the mpssd and ofed-mic initialization. They also noted that the application would hang if they used an offloaded code or an OpenCL code. Are you doing something similar?
