Trestles big picture
Trestles - Big Picture

  • Proposed as a high-productivity system for modest-scale/gateway users

    • Tailored to user/science needs

    • Establish policies and queues to maintain good throughput times – continuous tuning of allocations/utilization/scheduling

    • Also plan a queue for long-running jobs

  • Will be operated in parallel with Gordon

  • Nominal schedule

    • 10/1/10 – Two test nodes

    • 11/1/10 – Onsite build of production system starts

    • 12/1/10 – Friendly users begin

    • 01/1/11 –Full production

    • Operations till Dec 2013

Trestles configuring for productivity
Trestles - Configuring for productivity

  • Plan to allocate ~70% of the theoretically available SUs

    • The common practice is to allocate 80% (or more), which can result in high wait times. A 70% maximum will allow the scheduler to better satisfy a mix of scheduling modes, provide an opportunity to assess the impact of the other changes, and may be revised upward as we collect more data.

  • Cap allocation per project at 1.5M SUs/year (~2.5% of annual total).

    • Because projects with large percentage allocations dominate resource consumption and drive up queue waits, this cap not only creates room for more users, but also should reduce queue waits across the board.

  • Allow new users to request up to 50,000 SUs in startup allocations, and front-load the SUs offered during the first few allocations cycles.

    • This should foster expanding the user community from the outset and accelerate the frequently slow start-up for new systems.

  • Configure the job queues and resource schedulers for lower expansion factors and generally faster turnaround.

    • System data and user feedback will be used to make adjustments to these in order to achieve the optimum performance for each of the job classes

Sdsc summer high school research program
SDSC Summer High School Research Program

  • Six-week paid internships to help increase awareness of the life science industry and related fields of research to students in the San Diego region

  • Students gained exposure to career options, hands-on laboratory experience, work readiness skills, and mentoring by a company or research scientists

  • The success of the program has led to plans for future internships

  • 23 students participated at SDSC

  • Ended with a student poster presentation and reception August 12
