Question for using NI(National Instruments) PXIe-8135 connected NI-USRP-2943R with GNU Radio

Hello readers.
I am very new at using NI-USRP RIO & NI-PXIe.
I have some questions for using GNU Radio with NI-PXIe-8135.
I know that GNU Radio is very good program for using USRP, but there’s
no information about GNU Radio and NI-PXIe.

Can I use GNU Radio in NI-PXIe-8135 connected with USRP -2943R?
If GNU Radio can be used like that, Could you give me
information(Manual, examples)?

and

What is the difference between GNU Radio and LAB Windows/CVI? and which
one is better for using PXIe and USRP?

Please give me any comments.
Thank you for your reading.
