#176 closed defect (fixed)

GPU computing unusable on compute1

Reported by: Matthias Vogelgesang Owned by: Suren A. Chilingaryan
Priority: blocker Milestone:
Component: Infrastructure Version:
Keywords: Cc: Matthias Vogelgesang

Description

Nothing works. CUDA applications stop at cudaGetDeviceCount whereas OpenCL applications stop at calls to clCreateContext as reported by ltrace. Several cards report a significant memory consumption although no one is using them ATM.

I am increasing the priority because compute1 is necessary for me to test distributed computing.

It seems the problem is only with Card0 (GTX680). If you omit it in the CUDA_VISIBLE_DEVICES, it works at the moment. I'll check why the first device is crashing next several days.

I have updated drivers. Let me know if the problem with GTX680 is there again.
