The latest stable version is NetPIPE-3.7.1.tar.gz here, or follow this link for a list of old versions. We have added an InfiniBand module for the Mellanox VAPI, incorporated an integrity check option (-i), added the ability to test with and without cache effects, allowed offsets of the source and destination buffers, and fixed problems with the streaming mode.
Jimmy Hill contributed a uDAPL module for version 3.6.2 that you can download from the old versions directory. He is planning to contribute a uDAPL version for NetPIPE 4.x too, which will be integrated into the official distribution. A version of NetPIPE for Java is also available, based on the NetPIPE 2.4 C code.
NOTE: Version 3.6.2 fixes the bug causing segfaults in Red Hat Enterprise Linux systems (and most likely other distributions as well). Additionally, a number of portability issues with 64-bit architectures have been fixed.
NOTE: Version 3.6.1 fixes a bug in the InfiniBand module that arose from changes in the Mellanox VAPI code.
