Hub Counter README ------------------ Files: README.md - Instructions and explanantion of md interface README.io - Instructions and explanantion of io interface mdperfTest.c - simple example code of how to get some md counts ioperfTest.c - simple example code of how to get some io counts iobatch.c - More complicated test program showing how to extract io counts, good to examine for flexibility of interface, and some more examples all_iocount.txt - output of iobatch for 4 - node machine while monitoring all nodes node0_iocounts.txt - output of iobatch for 4 - node machine while monitoring node 0 Makefile - Shows what #defines are necessary hwperftypes.h - The offsets, includes, return values and other goodies to use the interface. Notes: 1) The code will not compile on any kernel but the one I have built, since I haven't checked it in. It is just there for reference. 2) The overflow bug in md should be fixed now. If there are any questions or problems please e-mail me at mhr@engr.sgi.com Also if anyone has a program that is using the ioctl interface please tell me so I can test it out with my changes. mhr
