About CDF and SILO

CDF

CDF (CDF) - Common Data Format - NASA-standard format for multidimensional scientific data. Best for space physics, heliophysics, and planetary science data.

SILO

SILO (SILO) - Silo - LLNL mesh and field data format for large-scale scientific simulations. Ideal for petascale simulation data, hydrodynamics, hpc visualization.

FAQs

Is converting CDF to SILO free?

Yes, GoConvertFile offers free conversion of CDF to SILO for files up to 100MB. No registration required.

How long does it take to convert CDF to SILO?

Most CDF to SILO conversions complete within seconds for standard-sized files. Larger files may take longer depending on the conversion complexity.

What is SILO best used for?

SILO is ideal for petascale simulation data, hydrodynamics, hpc visualization. Silo - LLNL mesh and field data format for large-scale scientific simulations

Does converting CDF to SILO lose quality?

Yes, converting CDF to SILO uses lossy compression, which reduces file size by discarding some visual data. Set quality to 85-95% for a good balance of quality and file size.

What file size should I expect after converting CDF to SILO?

SILO files are typically 50-80% smaller than CDF files because SILO uses efficient lossy compression. The exact reduction depends on quality settings.

What is CDF?

CDF (Common Data Format) is a NASA-standard, self-describing format for the storage and manipulation of scalar and multidimensional data in space and earth science.

What is SILO?

SILO is a portable file format developed at Lawrence Livermore National Laboratory for storing multi-dimensional mesh and field data, supporting structured grids, unstructured meshes, and point data for large-scale scientific simulations.

When Should You Use CDF vs SILO?

Use CDF When...

Reach for CDF when your priority is space physics, heliophysics, and planetary science data — its uncompromising quality ensures every detail is preserved.

Use SILO When...

Reach for SILO when your priority is petascale simulation data, hydrodynamics, hpc visualization — its efficient compression makes sharing fast and storage minimal.

CDF vs SILO: Key Differences

  • •The core technical difference: CDF relies on lossless compression whereas SILO uses lossy compression.
  • •Converting from CDF to SILO changes compression type: lossy source becomes smaller but with some quality tradeoff.
  • •Transparency: N/A - binary HDF5-based format — converting from CDF will merge transparency into a solid background
  • •CDF files are typically MB to GB for mission data while SILO files range 100MB to tens of GB per simulation step
  • •Use case fit: CDF targets space physics, heliophysics, and planetary science data and SILO targets petascale simulation data, hydrodynamics, hpc visualization — your choice depends on which workflow stage you are serving.

Advantages of CDF

  • ✓CDF uses lossless compression tailored for Space physics, heliophysics, and planetary science data.
  • ✓CDF is supported natively on virtually every device, browser, and operating system.
  • ✓CDF files are bit-for-bit perfect, preserving every pixel and sample for professional work.
  • ✓CDF integrates seamlessly with all major creative tools and workflows.

Advantages of SILO

  • ✓SILO compresses data using lossy methods, keeping file sizes manageable for Petascale simulation data, hydrodynamics, HPC visualization.
  • ✓Industry-wide support means SILO files open anywhere — from legacy systems to the latest devices.
  • ✓Small file sizes make SILO ideal for email, web uploads, and cloud storage.
  • ✓From professional software to open-source alternatives, SILO works out of the box.

Common Use Cases for CDF to SILO Conversion

Industry Applications

Best Practices for CDF to SILO Conversion

  • →When converting CDF to SILO: verify that variable names, units, and dimensions are preserved
  • →Preserve metadata and provenance attributes so SILO remains scientifically interpretable
  • →Check that multi-dimensional arrays (time, depth, lat, lon) map without truncation
  • →Confirm endianness and numeric precision are handled correctly for the target format output
  • →Always keep a backup of your original files before converting
  • →Choose the appropriate quality settings for your specific use case

Troubleshooting CDF to SILO Conversion

  • !SILO loses variables or dimensions converting from CDF → check that the target format supports the same rank/shape of arrays
  • !Units or scale look wrong in SILO → verify scaling factors and offset attributes were applied during CDF to SILO
  • !Metadata stripped from SILO output → preserve global and variable attributes for reproducibility
  • !CDF to SILO fails for large files → chunk the dataset or increase available memory before converting
