With h5dump you can specify which datasets you want to dump. I am sure nobody is going to use awk, grep and wc to process terabytes of data. As for sanity check

With h5dump you can specify which datasets you want to dump. I am sure nobody is going to use awk, grep and wc to process terabytes of data. As for sanity checks, like checking that probabilities stored in a dataset sum up to 1.0 and things like that, dumping one dataset and processing it with awk should be ok.

This example is working on gigabytes rather than terabytes of data, but memory utilization is basically limited to just buffers, so you could definitely scale that to terabytes without a problem. http://aadrake.com/command-line-tools-can-be-235x-faster-than-your-hadoop-cluster.html http://aadrake.com/command-line-tools-can-be-235x-faster-tha...
