GPUs not being utilized?

[reddingbacon]

Hi,

We have a new Fedora box with 2 GTX 690 cards (4 GPUs). We are trying to crack a single WPA hash in a .hccap file. We know the mask of the password and are running the following command but getting almost no performance from the GPUs.

./cudaHashcat-plus64.bin -m 2500 -a 3 captureTMGwpa.hccap ?l?l?l?d?l?s?l?l

Following is the output:

Hashes: 1 total, 1 unique salts, 1 unique digests
Bitmaps: 8 bits, 256 entries, 0x000000ff mask, 1024 bytes
