An empty cell means that the value was zero. | ID | time | GC time | memory | allocations | |------------------------------------------------------|----------------:|----------:|----------------:|------------:| | `["assemble", "basic bilinear", "mass matrix"]` | 16.352 ms (5%) | | 13.20 MiB (1%) | 51 | | `["assemble", "basic bilinear", "stiffness matrix"]` | 80.234 ms (5%) | | 13.20 MiB (1%) | 51 | | `["assemble", "poisson DG", "AffineFESystem"]` | 129.980 ms (5%) | 75.054 ms | 71.64 MiB (1%) | 17155 | | `["assemble", "poisson DG", "a_Γ(u, v)"]` | 38.994 ms (5%) | | 59.32 MiB (1%) | 13065 | | `["assemble", "poisson DG", "a_Γb(u, v)"]` | 7.394 ms (5%) | | 10.79 MiB (1%) | 3163 | | `["assemble", "poisson DG", "a_Ω(u, v)"]` | 7.693 ms (5%) | | 308.81 KiB (1%) | 29 | | `["assemble", "poisson DG", "l_Γb(v)"]` | 58.099 μs (5%) | | 139.38 KiB (1%) | 929 | | `["assemble", "poisson DG", "l_Ω(v)"]` | 12.354 μs (5%) | | 2.12 KiB (1%) | 1 | | `["covo", "Quad", "explicit_step"]` | 80.685 ms (5%) | | 29.25 MiB (1%) | 4398 | | `["covo", "Quad", "integral_surface"]` | 52.655 ms (5%) | | | | | `["covo", "Quad", "integral_volume"]` | 20.303 ms (5%) | | | | | `["covo", "TriQuad", "explicit_step"]` | 378.377 ms (5%) | 28.266 ms | 341.57 MiB (1%) | 1812323 | | `["covo", "TriQuad", "integral_surface"]` | 276.933 ms (5%) | | 234.44 MiB (1%) | 1424064 | | `["covo", "TriQuad", "integral_volume"]` | 61.882 ms (5%) | | 51.71 MiB (1%) | 379526 | | `["entities", "edges2nodes"]` | 1.552 ns (5%) | | | | | `["entities", "nedges"]` | 1.552 ns (5%) | | | | | `["entities", "nnodes"]` | 3.095 ns (5%) | | | | | `["entities", "nodes"]` | 1.572 ns (5%) | | | | | `["mesh", "todo"]` | 1.552 ns (5%) | | | | ## Benchmark Group List Here's a list of all the benchmark groups executed by this job: - `["assemble", "basic bilinear"]` - `["assemble", "poisson DG"]` - `["covo", "Quad"]` - `["covo", "TriQuad"]` - `["entities"]` - `["mesh"]` ## Julia versioninfo ``` Julia Version 1.10.5 Commit 6f3fdf7b362 (2024-08-27 14:19 UTC) Build Info: Official https://julialang.org/ release Platform Info: OS: Linux (x86_64-linux-gnu) Ubuntu 22.04.4 LTS uname: Linux 6.5.0-1025-azure #26~22.04.1-Ubuntu SMP Thu Jul 11 22:33:04 UTC 2024 x86_64 x86_64 CPU: AMD EPYC 7763 64-Core Processor: speed user nice sys idle irq #1 2835 MHz 2439 s 0 s 295 s 7715 s 0 s #2 3242 MHz 2611 s 0 s 264 s 7564 s 0 s #3 2445 MHz 2591 s 0 s 290 s 7578 s 0 s #4 2798 MHz 2235 s 0 s 278 s 7944 s 0 s Memory: 15.606491088867188 GB (12100.390625 MB free) Uptime: 1048.94 sec Load Avg: 1.04 1.17 0.87 WORD_SIZE: 64 LIBM: libopenlibm LLVM: libLLVM-15.0.7 (ORCJIT, znver3) Threads: 1 default, 0 interactive, 1 GC (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: 4890.86 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: Vulnerable: Safe RET, no microcode Vulnerability Spec store bypass: Vulnerable Vulnerability Spectre v1: Mitigation;
