+Introduction to the oneAPI Language SIG
+----------------------------------------
+
+Ruyman Reyes Castro (RRC)
+
+* oneAPI Language SIG Introduction
+
+  * OneAPI Language SIG is evolution from oneAPI Language TAB
+  * Main focus is feedback into SYCL language and C++ ISO interaction
+  * Looking into ideas from other languages and how they apply to
+    SYCL/C++
+  * Please send topics, suggested agendas
+
+Juan Jose Fumero (JJF): "TornadoVM: Multi Backend Hardware
+Acceleration Framework for Java"
+
+* `Slides <presentations/2023-03-14-TornadoVM.pdf>`__
+* TornadoVM is a programming model and API for accelerator offloading
+* Supports multiple backends, including Level Zero, OpenCL and CUDA
+* Relies on Graal and Graal IR for compiler and bytecode optimization
+* Defines a common IR format that then is lowered to target IR (PTX,
+  SPIR-V, OpenCL C)
+* Long list of feedback for Level Zero API design based on experience
+  interacting with level zero via JNI
+* RRC: That feedback is better directed to the HW SIG where the right
+  Level Zero and Unified Runtime people is, but many thanks.
+* Q&A:
+
+  * GS: Do you support other targets beyond SPIRV?
+  * JJF: We support SPIRV on Level Zero API. We use a third party
+    JAVA library to generate the SPIRV. We support OpenCL but not
+    SPIR-V. OpenCL SPIR-V should work.
+  * RRC: Your matrix multiplication slide shows you only add
+    annotation but you perform loop swap optimization, do you have
+    enough semantic information to trigger that optimization from
+    the Java IR?
+  * JJF: It is not highligted on the slides but we use a custom type
+    for the matrix type so we know is a 2D and we control the layout
+  * RRC: Your Task Graph API is similar to what is being designed
+    for SYCL-Graphs, so would be good to have your feedback there,
+    will conntect you to the right people
+  * JJF: I am not aware of the SYCL-Graph approach but happy to
+    collborate
+
+Post-meeting actions:
+
+* RRC connected JJF with oneAPI HW SIG to pass on the feedback
+* RRC connected JJF with team working on SYCL Graphs to discuss ideas
+  for the proposal
