yesterday, one of my hosts with a GTX750ti inside picked up the task
gpcrmd_4zj8_complex_withNA_rep_1-GIANNI_CPXB-1-10-RND4538_0

What worries me is that GPU-Z shows an increasing GPU memory load. Yesterday evening the value about 1400MB, this morning about 1600MB, and now, at noon, it is at 1816MB.
The memory size of the card is 2048GB.
Given that only 54% of the task is done so far, I guess that some time around this evening or so the limit will be reached, and the task will fail.

What seems interesting is that a similar GIANNI task running on one of my GTX980ti needs about 780MB GPU memory, this value staying pretty much stable all the time.

Anyone any idea what's happening?
