Department of Fisheries Oceanography "Linking Knowledge to Action for Climate Ready and Resilient fisheries the Gulf of Maine" Jocelyn Runnebaum, Marine Scientist, The Nature Conservancy Wednesday, October 23, 2024 3pm-4pm SMAST E 101-102 and via Zoom Abstract: Climate change is already and will continue to have far-reaching and multiscale impacts on fisheries, fisheries management, and fishing communities in the Gulf of Maine. Ocean temperatures are warming two to three times faster than the average global rate and commercial landings are near the lowest levels observed for this ecosystem, with several species experiencing historically low population levels. To understand New England harvester's perceptions of the impacts of climate change on themselves, their communities, the ecosystem, and commercially important species in the region we conducted a survey from Maine to Connecticut in 2020. We found that respondents wanted climate change and harvester observations to be considered in fisheries management. We also found that those that believe in climate change see themselves as more vulnerable to its impacts. Calls for fisheries to be climate-ready and climate-resilient have become almost ubiquitous across the fishery management system to with an aim to improve the adaptive capacity of harvesters and to sustain the resilience of changing ecosystems. However, it seems like the scientific information on climate change is not making its way into the fisheries management process in a timely manner. Through an evaluation of the fisheries management process, it is possible to identify how to link knowledge to action for achieving climate ready fisheries management. This includes understanding where specific onramps for climate information and place-based knowledge are in the current process and specific actions at each onramp for how to utilize climate and ecosystem information and diverse knowledge types to inform decision making. This will be a personal, policy, and scientific journey on striving for meaningful outcomes for the Gulf of Maine. For additional information, please contact Callie Rumbut at c.rumbut@umassd.edu

College of Engineering Computer & Information Science CIS Master's Thesis Defense by Dante Broggi Date & Time: Monday October 28, 2024 at 3:30 pm Thesis Advisor: Dr. Adnan El-Nasan Committee Members: Dr. Firas Khatib and Professor Clinton Rogers Join Zoom Meeting https://umassd.zoom.us/j/5039281530?pwd=Qnp6dGNlQVFPam5saHJWb3YyQ3dBQT09 Meeting ID: 503 928 1530 Passcode: 582509 Abstract: Many common programming languages (C, C++, Rust, Swift) provide an API to enable programmers to access atomic operations for use by multithreaded algorithms such as parallelized searches and to provide access to data structures such as concurrent linked lists. We investigated atomic operations in Rust and added wide pointer atomic support to mitigate the ABA problem in a way that is based on the solution supported in the Pony runtime. The ABA problem is a general problem scenario in which a function falsely assumes that atomically loading bitwise equivalent values means nothing relevant has changed between the loads. This can occur due to an algorithm failure, or due to object allocation reuse for logically distinct objects. We added experimental support for wide pointers with a 64-bit counter alongside the 64-bit pointer. This circumvents the ambiguity of having 2 or more pointers that point to the same address but are semantically different. Such pointers can occur, for example, when one is created in such a way that permits reading a whole array while the other is intended to read or write only the first element, or one was recently deallocated (these additional semantic differences are called the pointers provenance data). Rust extensively uses pointer provenance data to optimize its reference types by implementing their documented exclusivity and immutability guarantees. We implemented the standard atomic operations of load, store, and compare and swap (CAS) on Rust-wide pointers, both in the Rust intermediate representation interpreter Miri and in the LLVM backend, in a way that preserves provenance without hindering later optimization by exposing it unnecessarily. This implementation was assessed using several individual-operation correctness tests and an analysis of how our solution changes the result of a case of the ABA problem in a stack. We also tested the API design against that desired by our preceding attempt at translating the Pony runtime into Rust [1], where this or similar API is one of the blockers to further progress. We found that the proposed API is satisfactory, and the implementation passes the correctness tests and avoids internal ABA problems in all test cases.
