Nvidia Titan V is said to give incorrect calculation results

In December last year, it was time for the architecture Volta to find out to consumers in the form of Titan V. The architecture was previously found in Nvidia’s calculation card Quadro, but these were not intended for consumers. The end result was the most expensive Titan card to date with the price tag of SEK 31,500 and a circuit of 815 mm².

Now The Register reports that the graphics card in some applications gives incorrect calculation results. Specifically, these are scientific models and simulations where the circuit must perform complex calculations.

A research team working on interactions between proteins and enzymes claims that Titan V gives numerically incorrect results in about ten percent of the simulations. It is worth mentioning that this applies to completely identical simulations that have been repeated over and over again, and which should give the same result every time.

An anonymous engineer involved in the project also states that four different Titan Vs were used to exclude incorrect copies. The result was the same for all four. Previous generations of Nvidia’s graphics cards gave accurate results instead. However, the problem is not said to affect game-related calculations.

Nvidia has been notified of the bug and is said to be aware of it. A representative of the company stated that the Amber software is affected by the problem, and that users should report such problems directly to the graphics maker upon emergence.
