Our Story
A Drive Toward Sustainable Integrated Open Source Software
Trenza Synergy team members have decades of experience in High Performance Computing with prior history at Cray Inc. and SGI and involvement in DOE NNSA HPC performance analysis tool development and deployment.
Our development of proprietary performance analysis tools began with Open|SpeedShop (O|SS), designed for deep analysis of an applications resource use on a large HPC system (product is still supported). We originally conceived of the Survey framework while working on O|SS. The DOE NNSA laboratories were looking for lightweight performance collectors that had low overhead but broad metric collection. This concept of a summary tool morphed into the Survey framework. It was a couple of years in the making and has been further enhanced and hardened through recent development contracts with the DOE. We are now helping teams integrate the Survey framework into their daily processes, from development teams utilizing continuous integration (CI) to system support teams looking to ensure that their system resource offerings remain healthy through upgrades and changes.
Our model for sustainability was to find the balance between open source and proprietary, per-node licensed software products. We decided to use a flexible subscription model that provides a substantial portion of the value to support integration troubleshooting and assistance for system and development teams. We want to ensure you have the support to receive value from our tools and in turn learn from you what you need to be successful.
Our expert team provides support to development teams to deliver the metrics to insight conversion that can help them further their plans. Close collaboration with our clients’ teams have been invaluable in developing our own product roadmap; using our Survey framework to support other teams provides us with insight to make our tools better.

Our Team
David Montoya
Founder & President
David has over two decades of experience in High Performance Computing (HPC) software environments, tools and collaborative development. Trenza was created to build on experiences, tools, and collaborative opportunities in HPC and other compute intensive markets to optimize utilization. The company is small but focused on working with customers to refine the products and services that will help them in the long run. Prior to establishing Trenza, he held positions at Los Alamos National Laboratory in support of HPC software strategy and support, workload and workflow characterization, and was the software deployment lead for the DOE Exascale Computing Project.
Jim Galarowicz
Founding Member, Operational Lead
Jim has over four decades in High Performance Computing (HPC) in tool development, deployment, and project leadership. Prior to Trenza, he led, developed, and was key in the deployment of the Open|SpeedShop performance tool development effort through The Krell Institute in support of the DOE NNSA laboratories. Earlier, he also worked on compilers, debuggers, and performance tool development effort at both Cray and SGI.
Donald Maghrak
Founding Member, Development Lead
Donald has over three decades in High Performance Computing (HPC) in tool development. Prior to Trenza, he was the core developer for performance collectors and infrastructure in the Open|SpeedShop performance tool development effort through The Krell Institute in support of the DOE NNSA laboratories. Earlier, he also worked on compilers, debuggers, and performance tool development effort at both Cray and SGI.
Kristina Frye
Founding Member, Analytics Lead
Kristina is key in supporting efforts to translate performance data into insight and analysis. A researcher at heart, she provides a perspective of state of the art external efforts that add to Trenza offerings. She is a recent Portland State University alum and has served on internships at Los Alamos National Laboratory and the New Mexico Consortium.
Mahesh Rajan
Performance Study Lead
Before retiring from Sandia National Labs in 2017, he was a Distinguished Member of the Technical Staff (DMTS) working on DOE-NNSA Tri-Lab HPC procurements and as acceptance tests lead, focusing on scalability and application performance. Before Sandia he had held a tenured faculty position and also served as HPC application specialist for a number of HPC companies: HP, IBM, Intel, MasPar, Supercomputing Solutions, Inc.
