Summary: swift_mpi is Compute-bound in this configuration
Compute: 96.8% |=========|
MPI: 0.5% ||
I/O: 2.8% ||
This application run was Compute-bound. A breakdown of this time and advice for investigating further is in the CPU section below.
As very little time is spent in MPI calls, this code may also benefit from running at larger scales.
CPU:
A breakdown of the 96.8% CPU time:
Scalar numeric ops: 24.3% |=|
Vector numeric ops: <0.1% ||
Memory accesses: 61.8% |=====|
The per-core performance is memory-bound. Use a profiler to identify time-consuming loops and check their cache performance.
No time is spent in vectorized instructions. Check the compiler's vectorization advice to see why key loops could not be vectorized.
MPI:
A breakdown of the 0.5% MPI time:
Time in collective calls: 100.0% |=========|
Time in point-to-point calls: 0.0% |
Effective process collective rate: 919 kB/s
Effective process point-to-point rate: 0.00 bytes/s
I/O:
A breakdown of the 2.8% I/O time:
Time in reads: 16.7% |=|
Time in writes: 83.3% |=======|
Effective process read rate: 143 MB/s
Effective process write rate: 53.9 MB/s
Most of the time is spent in write operations with a low effective transfer rate. This may be caused by contention for the filesystem or inefficient access patterns. Use an I/O profiler to investigate which write calls are affected.
Threads:
A breakdown of how multiple threads were used:
Computation: 53.7% |====|
Synchronization: 46.3% |====|
Physical core utilization: 197.3% |===================|
System load: 140.2% |=============|
Significant time is spent synchronizing threads. Check which locks cause the most overhead with a profiler.
Multiple threads per physical core may be causing contention. Using fewer threads may improve performance for some codes.
Memory:
Per-process memory usage may also affect scaling:
Mean process memory usage: 394 MiB
Peak process memory usage: 442 MiB
Peak node memory usage: 0.0% |
Node memory usage metrics:
Energy:
A breakdown of how energy was used:
CPU: not supported
System: not supported
Mean node power: not supported
Peak node power: 0.00 W
Energy metrics are not available on this system.
CPU metrics are not supported (no intel_rapl module)
