From d48231502a067b4a6f8e50e62b6b3328c44fca44 Mon Sep 17 00:00:00 2001 From: Sandro Wenzel Date: Thu, 24 Sep 2026 22:41:13 +0200 Subject: [PATCH 01/28] Write tracked V0s, cascades and 3-bodies in collision order (#15838) * Write tracked V0s, cascades and 3-bodies in collision order This fixes the row order of the tracked strangeness tables written by the AOD producer. - The tracked V0, cascade and 3-body rows were written in strangeness-tracker order, which is not always collision order. - Analyses slicing them by collision then abort with "TraCascIndices index fIndexCollisions is not sorted". - The rows are now written in the per-collision order already built in prepareStrangenessTracking. - The track index of a row no longer comes from a running counter, so a skipped strange track cannot shift the rows after it. https://its.cern.ch/jira/browse/O2-7197 * Keep strange tracks in decay order also with one vertexer thread This makes the order of the tracked strangeness tables within a collision the same in MC as in data. - SVertexer sorted the strange tracks by decay only when running with more than one thread; MC reconstruction runs it with one. - The strange tracks are now sorted by decay in all cases. - The AOD producer groups them by collision with a stable sort, so the decay order within a collision is kept. https://its.cern.ch/jira/browse/O2-7197 Co-Authored-By:

The processing settings block in GPUSettingsList.h is skipped for OpenCL because it declares std::string and std::vector members, which GPUSettings.h explicitly does not include for device code. Metal needs the same exclusion. These configs are host-side only: GPUParam carries GPUSettingsRec and GPUSettingsParam, and the processing settings appear only as pointer arguments to host methods, so nothing transferred changes shape. GPUCommonBitSet already carries an extra constructor for OpenCL's __constant. Metal needs the opposite: MSL will not use a user-declared copy constructor to build an object in the constant address space, which is where GPUconstexpr() arrays of bitset live, and leaving the copy constructor implicit makes them constructible again. That one line accounted for 84 of the remaining diagnostics, across DetID and GlobalTrackID. Metal translation unit: 136 errors to 27. --- GPU/GPUTracking/Definitions/GPUSettingsList.h | 4 ++-- GPU/Utils/GPUCommonBitSet.h | 5 +++++ 2 files changed, 7 insertions(+), 2 deletions(-) diff --git a/GPU/GPUTracking/Definitions/GPUSettingsList.h b/GPU/GPUTracking/Definitions/GPUSettingsList.h index 4e3e0cd32d752..81949f0b8ed2a 100644 --- a/GPU/GPUTracking/Definitions/GPUSettingsList.h +++ b/GPU/GPUTracking/Definitions/GPUSettingsList.h @@ -221,7 +221,7 @@ AddSubConfig(GPUSettingsRecDynamic, dyn) AddHelp("help", 'h') EndConfig() -#ifndef __OPENCL__ +#if !defined(__OPENCL__) && !defined(__METAL__) // these use std::string / std::vector, which device code does not have // Parameters that might affect the RTC code (if these change, the cache cannot be used) BeginSubConfig(GPUSettingsProcessingRTC, rtc, configStandalone.proc, "RTC", 0, "Processing settings", proc_rtc) AddOption(cacheOutput, bool, false, "", 0, "Cache RTC compilation results") @@ -428,7 +428,7 @@ AddSubConfig(GPUSettingsProcessingNNclusterizer, nn) AddSubConfig(GPUSettingsProcessingScaling, scaling) AddHelp("help", 'h') EndConfig() -#endif // __OPENCL__ +#endif // !__OPENCL__ && !__METAL__ #ifndef GPUCA_GPUCODE_DEVICE // Light settings concerning the event display (can be changed without rebuilding vertices) diff --git a/GPU/Utils/GPUCommonBitSet.h b/GPU/Utils/GPUCommonBitSet.h index 302334e01e29d..e35587ab60c7b 100644 --- a/GPU/Utils/GPUCommonBitSet.h +++ b/GPU/Utils/GPUCommonBitSet.h @@ -37,7 +37,12 @@ class bitset public: GPUdDefault() constexpr bitset() = default; +#ifndef __METAL__ + // MSL will not use a user-declared copy constructor to build an object in the + // constant address space, where GPUconstexpr() arrays of bitset live.

only deltaIntersection does, and it stays at 1e-5 mm. - minimumEpsilon controls the long steps; relaxing it to 1e-4 moves nothing in the barrel, but it would move MCH positions, so YOUT1, DDIP and YOUT2 keep the tight values. - G4LocalFieldConstruction attaches the global field to every volume given its own parameters with /mcDet/createMagFieldParameters, so that the /mcMagField// settings take effect. - A volume whose subtree contains zero-field media is refused, since Geant4 VMC forces a local field onto all daughters. - This saves about 10% of the transport CPU time in pp. https://its.cern.ch/jira/browse/O2-7198 https://alice.its.cern.ch/jira/browse/ALIROOT-7121 Co-Authored-By: Claude Opus 5.5 --- Detectors/gconfig/CMakeLists.txt | 2 +- Detectors/gconfig/g4Config.C | 5 +- Detectors/gconfig/g4config.in | 29 ++++++- .../SimSetup/G4LocalFieldConstruction.h | 37 ++++++++ .../include/SimSetup/G4RunConfiguration.h | 2 +- .../gconfig/src/G4LocalFieldConstruction.cxx | 87 +++++++++++++++++++ Detectors/gconfig/src/G4RunConfiguration.cxx | 3 +- 7 files changed, 155 insertions(+), 10 deletions(-) create mode 100644 Detectors/gconfig/include/SimSetup/G4LocalFieldConstruction.h create mode 100644 Detectors/gconfig/src/G4LocalFieldConstruction.cxx diff --git a/Detectors/gconfig/CMakeLists.txt b/Detectors/gconfig/CMakeLists.txt index d4f446f0c43be..a1a2b426f2bb4 100644 --- a/Detectors/gconfig/CMakeLists.txt +++ b/Detectors/gconfig/CMakeLists.txt @@ -15,7 +15,7 @@ o2_add_library(G3Setup ) o2_add_library(G4Setup - SOURCES src/G4Config.cxx src/G4RunConfiguration.cxx + SOURCES src/G4Config.cxx src/G4RunConfiguration.cxx src/G4LocalFieldConstruction.cxx PUBLIC_LINK_LIBRARIES MC::Geant4VMC MC::Geant4 FairRoot::Base O2::SimulationDataFormat O2::Generators O2::SimSetup O2::FastSim ) diff --git a/Detectors/gconfig/g4Config.C b/Detectors/gconfig/g4Config.C index 17f28c7369e67..83a932e674e5b 100644 --- a/Detectors/gconfig/g4Config.C +++ b/Detectors/gconfig/g4Config.C @@ -119,9 +119,8 @@ void Config() LOG(fatal) << "Unsupported geometry navigation mode";
