Total Wave Size limit > 20 GB

Share icon

Hello,

I am wondering is it possible to lift this limit somehow in a future release?
Although it might sound ridiculous, in our data acquisition waves can grow really huge easily.
In some cases, with 20 GB of wave size limit the data acquisition cannot be longer than 20s. (Every 20s we will have to stop the acquisition, process and delete or dump the raw data to drive).

I don't know much about the memory management of OS so I can't really tell if this is a fundamental technical issue so it would be great if anyone can provide some insights about it.

I would say that this is not technical limitation rather than a "most users will not need more"-limit.

Just out of curiosity. How much RAM does your machine has if you routinely work with 20GB waves?

At the moment we don't really have much more than that, the lab computers are from 32 to 64 GB of RAM, and only a certain applications can utilize that much.
But for the acquisition I think we may get up to 128 GB RAM, they are now pretty cheap with DDR4, though recently the NAND prices went up a bit.

If you need the wave limit to be increased I would contact the WaveMetrics support directly.
