Add Boris recipe #141

Closed henry2004y closed 4 months ago

henry2004y commented 5 months ago

This PR now becomes a major rework of the native Boris method types and the TestParticleMakie recipe. See more in #142.

This will close #142.

While developing this part, I also encountered the bug which will be fixed by https://github.com/SciML/DiffEqBase.jl/pull/1004.

An empty cell means that the value was zero. | ID | time | GC time | memory | allocations | |-----------------------------------------------------|---------------:|--------:|---------------:|------------:| | `["trace", "analytic field", "in place"]` | 8.897 μs (5%) | | 10.56 KiB (1%) | 114 | | `["trace", "analytic field", "out of place"]` | 5.665 μs (5%) | | 8.72 KiB (1%) | 88 | | `["trace", "numerical field", "Boris ensemble"]` | 3.138 μs (5%) | | 880 bytes (1%) | 16 | | `["trace", "numerical field", "Boris"]` | 1.607 μs (5%) | | 672 bytes (1%) | 13 | | `["trace", "numerical field", "in place"]` | 23.093 μs (5%) | | 12.81 KiB (1%) | 114 | | `["trace", "numerical field", "out of place"]` | 14.507 μs (5%) | | 9.92 KiB (1%) | 88 | | `["trace", "time-dependent field", "in place"]` | 9.247 μs (5%) | | 11.31 KiB (1%) | 123 | | `["trace", "time-dependent field", "out of place"]` | 6.858 μs (5%) | | 9.50 KiB (1%) | 97 | ## Benchmark Group List Here's a list of all the benchmark groups executed by this job: - `["trace", "analytic field"]` - `["trace", "numerical field"]` - `["trace", "time-dependent field"]` ## Julia versioninfo ``` Julia Version 1.10.0 Commit 3120989f39b (2023-12-25 18:01 UTC) Build Info: Official https://julialang.org/ release Platform Info: OS: Linux (x86_64-linux-gnu) Ubuntu 22.04.3 LTS uname: Linux 6.2.0-1019-azure #19~22.04.1-Ubuntu SMP Wed Jan 10 22:57:03 UTC 2024 x86_64 x86_64 CPU: AMD EPYC 7763 64-Core Processor: speed user nice sys idle irq #1 2766 MHz 2631 s 0 s 178 s 3218 s 0 s #2 3363 MHz 2795 s 0 s 160 s 3073 s 0 s #3 3345 MHz 2120 s 0 s 175 s 3720 s 0 s #4 2445 MHz 1701 s 0 s 176 s 4136 s 0 s Memory: 15.60690689086914 GB (13717.046875 MB free) Uptime: 605.18 sec Load Avg: 1.04 1.38 0.87 WORD_SIZE: 64 LIBM: libopenlibm LLVM: libLLVM-15.0.7 (ORCJIT, znver3) Threads: 1 on 4 virtual cores ``` --- # Runtime information | Runtime Info | | |:--|:--| | BLAS #threads | 2 | | `BLAS.vendor()` | `lbt` | | `Sys.CPU_THREADS` | 4 | `lscpu` output: Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Address sizes: 48 bits physical, 48 bits virtual Byte Order: Little Endian CPU(s): 4 On-line CPU(s) list: 0-3 Vendor ID: AuthenticAMD Model name: AMD EPYC 7763 64-Core Processor CPU family: 25 Model: 1 Thread(s) per core: 2 Core(s) per socket: 2 Socket(s): 1 Stepping: 1 BogoMIPS: 4890.84 Flags: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt pdpe1gb rdtscp lm constant_tsc rep_good nopl tsc_reliable nonstop_tsc cpuid extd_apicid aperfmperf pni pclmulqdq ssse3 fma cx16 pcid sse4_1 sse4_2 movbe popcnt aes xsave avx f16c rdrand hypervisor lahf_lm cmp_legacy svm cr8_legacy abm sse4a misalignsse 3dnowprefetch osvw topoext invpcid_single vmmcall fsgsbase bmi1 avx2 smep bmi2 erms invpcid rdseed adx smap clflushopt clwb sha_ni xsaveopt xsavec xgetbv1 xsaves clzero xsaveerptr rdpru arat npt nrip_save tsc_scale vmcb_clean flushbyasid decodeassists pausefilter pfthreshold v_vmsave_vmload umip vaes vpclmulqdq rdpid fsrm Virtualization: AMD-V Hypervisor vendor: Microsoft Virtualization type: full L1d cache: 64 KiB (2 instances) L1i cache: 64 KiB (2 instances) L2 cache: 1 MiB (2 instances) L3 cache: 32 MiB (1 instance) NUMA node(s): 1 NUMA node0 CPU(s): 0-3 Vulnerability Gather data sampling: Not affected Vulnerability Itlb multihit: Not affected Vulnerability L1tf: Not affected Vulnerability Mds: Not affected Vulnerability Meltdown: Not affected Vulnerability Mmio stale data: Not affected Vulnerability Retbleed: Not affected Vulnerability Spec rstack overflow: Mitigation; safe RET, no microcode Vulnerability Spec store bypass: Vulnerable Vulnerability Spectre v1: Mitigation; usercopy/swapgs barriers and __user pointer sanitization Vulnerability Spectre v2: Mitigation; Retpolines, STIBP disabled, RSB filling, PBRSB-eIBRS Not affected Vulnerability Srbds: Not affected Vulnerability Tsx async abort: Not affected | Cpu Property | Value | |:------------------ |:---------------------------------------------------------- | | Brand | AMD EPYC 7763 64-Core Processor | | Vendor | :AMD | | Architecture | :Unknown | | Model | Family: 0xaf, Model: 0x01, Stepping: 0x01, Type: 0x00 | | Cores | 16 physical cores, 16 logical cores (on executing CPU) | | | No Hyperthreading hardware capability detected | | Clock Frequencies | Not supported by CPU | | Data Cache | Level 1:3 : (32, 512, 32768) kbytes | | | 64 byte cache line size | | Address Size | 48 bits virtual, 48 bits physical | | SIMD | 256 bit = 32 byte max.
