<div>EOD</div><div><br></div><div>1) I'm running the NASA Parallel Benchmark. It has classes A to F which determine how large the benchmark is, and the number of MPI processes to run on which is the last digit (1, 2, 4, 8...128). Out of the 43 such benchmarks, 22 gave the correct result. For the remaining either the output size is zero, half complete output or no output at all. If the run any of these failed benchmarks individually, they run correctly.</div>
<div><br></div><div>2) I've found a few bugs, have got a few log files (around 22). What is the best way to submit those?</div><div><br></div><div>Thanks</div><div>Ashish</div><div class="gmail_extra"><br><br><div class="gmail_quote">
