Presented on June 12, 2025, at Sigmetric 2025 (Stony Brook, New York, USA), this work shows that UINTRs enable inter-processor interrupts to be handled directly in user mode, without kernel intervention. The results demonstrate a significant improvement in the responsiveness of inter-process communications, with time quanta in the order of microseconds\u2014an asset for distributed systems and real-time applications, which are at the heart of the challenges of the DiVa project.<\/p>\n\n\n\n<p class=\"has-text-align-left\"><strong><em>The paper is available on <a rel=\"noreferrer noopener\" href=\"https:\/\/hal.science\/hal-05115268\" target=\"_blank\">HAL\u00a0<\/a><\/em><\/strong><\/p>\n\n\n\n<p><strong><em>Page on <a rel=\"noreferrer noopener\" href=\"https:\/\/dl.acm.org\/doi\/10.1145\/3727132\" target=\"_blank\">ACM DL<\/a><\/em><\/strong><\/p>","protected":false},"excerpt":{"rendered":"<p>New publication on Intel user interrupts: a step forward for the DiVa project The KrakOS (Louis Duval, Renaud Lachaize, Alain Tchana) and SEPIA (Yves Kone, Daniel Hagimont) teams, in collaboration with Pascal Felber (University of Neuch\u00e2tel), have just published a major study as part of the DiVa project.
