While strace is often used for troubleshooting and debugging, you can also use strace to get started on examining the I/O pattern of your serial codes.

In the last installment of our Parallel Platters series, Jeff Layton looks at the next generation of parallel file systems: Object Based File Systems.

Getting the most out of your cluster is always important. But how exactly is that done? Do you really need to dissect your code and analyze every instruction to get optimal performance? Do you need to build custom kernels? Not necessarily. By testing some basic assumptions, you may be able to eke ten-node performance out of an eight-node cluster. Here’s how.
