Performance Metrics
CryoSPARC Live is built and tuned for high performance pre-processing and streaming reconstruction of single particle data, and can use multiple concurrent GPUs for to maximize throughput.
CryoSPARC Live preprocessing includes four steps: (1) motion correction, (2) CTF estimation, (3) particle picking and (4) extraction.
CryoSPARC Live can sustain a throughput of 450 or more exposures per hour, per GPU, for K3 data. On a 4-GPU machine, that can scale to 1800+ exposures per hour! For K2 or Falcon data, performance can be even higher, upwards of 650 exposures per hour per GPU.
Depending on your hardware configuration (particularly raw data storage disk access speed), each preprocessing worker can sustain a throughput of at least one movie every 30 seconds, which is equal to ~2,500 movies per day per GPU.
In our internal tests, we have seen performance on well-tuned systems (like the testing hardware below) reaching up to 8,000 movies per GPU per day. See the Hardware Configurations used for Benchmarking section to see details on what hardware was used to run the benchmarks.
All 3D renderings were captured in ChimeraX from maps created by cryoSPARC Live.
All pre-processing timings were measured with Configuration 1, unless otherwise noted.
