The recent emergence of fast, dense, nonvolatile main memory suggests that certain long-lived data might remain in its natural pointer-rich format across program runs and hardware reboots. Operations on such data must be instrumented with explicit write-back and fence instructions to ensure consistency in the wake of a crash. Techniques to minimize the cost of this instrumentation are an active topic of research. We present what we believe to be the first general-purpose approach to building

... fered durably linearizable persistent data structures, and a system, Montage, to support that approach. Montage is built on top of the Ralloc nonblocking persistent allocator. It employs a slow-ticking epoch clock, and ensures that no operation appears to span an epoch boundary. It also arranges to persist only that data minimally required to reconstruct the structure after a crash. If a crash occurs in epoch e, all work performed in epochs e and e-1 is lost, but work from prior epochs is preserved. We describe the implementation of Montage, argue its correctness, and report unprecedented throughput for persistent queues, sets/mappings, and general graphs.

Tuberculosis is such a part of our everyday lives that I have never stopped to consider the illness experience regularly lived by our patients. As a seasoned family physician in public service, I have initiated hundreds of patients on tuberculosis treatment, simply informing them of their diagnosis and advising them to go to the clinic to obtain their medication. Even with the use of a patient-centred approach and shared decision-making, I did not give much thought to understanding the

The Partitioned Global Address Space (PGAS), a memory model in which the global address space is explicitly partitioned across compute nodes in a cluster, strives to bridge the gap between shared-memory and distributed-memory programming. To further bridge this gap, there has been an adoption of global-view distributed data structures, such as 'global arrays' or 'distributed arrays'. This work demonstrates how shared-memory data structures can be modified to scale in distributed memory.

This article reports on the findings of a workshop held at the joint 5th World Organisation of Family Doctors (WONCA) Africa and 20th National Family Practitioners Conference in Tshwane, South Africa, in 2017. Postgraduate training for family medicine in Africa takes place in the clinical workspace at the bedside or next to the patient in the clinic, district hospital or regional hospital. Direct supervisor observation, exchange of reflection and feedback, and learning conversations between the

... supervisor and the registrar are central to learning and assessment processes.Objectives: The aim of the workshop was to understand how family medicine registrars (postgraduate trainees in family medicine) in Africa learn in the workplace.Methods: Thirty-five trainers and registrars from nine African countries, the United Kingdom, United States and Sweden participated. South Africa was represented by the universities of Cape Town, Limpopo, Pretoria, Sefako Makgatho, Stellenbosch, Walter Sisulu and Witwatersrand.Results: Six major themes were identified: (1) context is critical, (2) learning style of the registrar and (teaching style) of the supervisor, (3) learning portfolio is utilised, (4) interactions between registrar and supervisor, (5) giving and receiving feedback and (6) the competence of the supervisor.Conclusion: The training of family physicians across Africa shares many common themes. However, there are also big differences among the various countries and even programmes within countries. The way forward would include exploring the local contextual enablers that influence the learning conversations between trainees and their supervisors. Family medicine training institutions and organisations (such as WONCA Africa and the South African Academy of Family Physicians) have a critical role to play in supporting trainees and trainers towards developing local competencies which facilitate learning in the clinical workplace dominated by service delivery pressures.

Emergency centres (ECs) provide emergency care to people with acute trauma and illness who require the services and expertise available at a hospital. 1 However, the presenting complaints at an EC overlap considerably with those encountered at primary healthcare (PHC) level. 2 Studies suggest that one-third to two-thirds of patients attend ECs with problems that could have been managed at a PHC level.

... e) 6-7 is routinely used at George Provincial Hospital to triage patients presenting to the EC to determine their acuity level and prioritise them accordingly. The five categories are red (immediate care), orange (very urgent care), yellow (urgent care), green (routine care) and blue (dead). A retrospective descriptive study at George Hospital in May 2010 to determine the after-hours case mix and workload 8 demonstrated that 65% of patients who presented to the EC after-hours were triaged green. This demonstrated that many low-acuity patients are seen in the EC. From the perspective of service delivery this 'inappropriate' attendance is problematic, as it competes for the attention of EC staff and potentially compromises the quality of care for more serious cases needing urgent treatment. A need was identified to determine the patient-specific reasons for presenting to a secondary hospital EC with PHC problems.
