December 8th, 2009

Marcos reported a slowdown in create_racer in 1.6 as compared to 1.4. lvb_torture and write_torture were fine.

create_racer is a mpi enabled app that does file creates from nodes in a round-robin manner. The remaining nodes access() the new file. The test ran with 40000 iterations (one create and lookup per iteration). The output was stored in a common outlog in another ocfs2 volume. Have asked Marcos to rerun with a local outlog to separate out the create and the datawrite traffic.
