hashcat Forum

Running on a small cluster with two nodes with centos 7. One node has a Nvidia K20 and the other a K80. I know these are are terrible for password cracking but this is the hardware config. The error I'm having is in regard to no locks being available. I've killed all hashcat instances with a kill -9. I've tried a clean installation of cuda and drivers. Also, hashcat runs perfectly fine on the node with the K20.
Below is the command and hashcat output:

./hashcat -m 500 -a 3 newMD5.2.txt

ERROR: Failed acquiring write lock: No locks available

Please upgrade to latest beta and retry

Error is resolved. It had to deal with a locality issue. Probably should've mentioned that I have a shared file system with NFS mount. Had to do a local install of hashcat onto each node that has a GPU.
