Hi ink,
Since we're now able to ship all needed CUDA tools and libraries with the 10.0 compilers, you no longer need to create a sitenvrc file.
My best guess as the cause of the gfec error is a mismatch in CUDA versions and that you should remove the sitenvrc file from your 10.0 installation.
Did NVDEBUG help in determining where the hang occurs?

it turned out that sitenvrc still needs to be setup manually and i forgot about it. (it is a bit strange that even small incremental updates eg from 9.0-3 to 9.0-4 could not pick it up automatically).
moving on. i'm getting now
gfec: error: unrecognized option `-TARG:abi=n64'
without sitenvrc the code can be compiled but hangs (even if sitenvrc is created after the code was compiled)
with sitenvrc i'm getting the error |
A PGI expert confirmed me that sitenvrc doesn't need anymore with PGI v10.0 |

well, it could be the cards on the two nodes that i used were in some bad state. i'm not quite sure. i removed sitenvrc, rebooted the nodes and also tried another node. i can compile my code with 10.0 and run it but it runs a few times slower than the 9.0-4 binary
if i set NVDEBUG=1 i see
__pgi_cu_init() found 4 devices
__pgi_cu_init() will use device 0 (V1.3)
__pgi_cu_init() compute context created
etc
so the card seems to be used |
