The initial charter which instigated the activities accessible through this portal was as follows:
- Identify major IO performance bottlenecks when accessing the Lustre file-system on Red Storm.
- Propose follow-on project plan to resolve the bottlenecks.
- Generalize the performance analysis methodology for subsequent use.
- Consider applicability of other Sandia IO initiatives as work progresses.
In response to this initial charter the "Rationale and Plan for the Red Storm IO Risk Mitigation Project" was drafted. A timeline of activities can be found here. A brief description of each test follows, along with a link to detailed information in graph and textual form.
TEST1 - Single client, file-per-process, increasing stripe(transfer) size.
TEST2 - Increasing client, file-per-process, 1 stripe.
TEST3 - Increasing client, file-per-process, 2 stripe.
TEST4 - Increasing client, file-per-process, 2 stripe, limited OST's, 60:1 oversubscription.
TEST5 - Increasing client, shared-file-access, 8 stripe, limited OST's, 60:1 oversubscription.
