In the second article of this three-part series, we look at simple write examples in Fortran 90 and track the output with strace to see how it affects I/O patterns and performance. ... the examples in this series because the I/O is so small; however, my focus is not really on the throughput itself, but on the I/O pattern.) The strace output in Figure 3F is for 500 iterations ...

-PA500B 500GB unit [2], priced around $123 at the time of writing. As a second-generation USB 3.1 device, the interconnect maxes out at 10Gbps, making external drive benchmarking a problem of the past ... We kick the tires of a Samsung 500GB SSD that promises a transfer rate of 540MBps. ... Testing the Samsung MU-PA500B 500GB SSD

. That is nearly six times the throughput of the HDD. On a more modern and faster system, that number should and would be higher: about 16 times the throughput or more. Random access I/O is where the memory device

found in HPC. It is also used as part of the IO500 [13] list. You can use it to test really large amounts of I/O and vary the I/O function payload size, as well as either read or write operations

explore how to define baselines for I/O, including the storage and network subsystems. The I/O paths are more vulnerable to performance setbacks because of system or software misconfiguration than CPU ... Defining I/O baselines helps you determine the highest performance you can expect from your system when configured properly.

] stacked under the controller's packaging, a way to smooth over the flash's garbage collection pauses I examined in this summer's column [9]. This kind of cache is an advantage of spinning media and SSD
