Agenda
- Nexedi
- Wendelin Concept
- Wendelin Use Case in Wind Energy
- Wendelin Use Case in Civil Engineering
- Conclusion
The presentation has three parts.
First we provide some information about Nexedi.
Then we present Wendelin and show how it is used in Wind Energy.
Then we explain some of the unique features of Wendelin by providing another use case of Wendelin: Civil Engineering.
Then we summarise our presentation for Total-Eren

IT Problems
- Reliable data collection
- Scalable storage
- Parallel processing
- Out-of-core processing
- Predictive algorithms
Introducing Wendelin
Reliable data collection: Fluentd
Scalable storage: NEO
Parallel Processing: ERP5
# Initialize data
data_size = 1e6
server_count = 1000
chunk_size = data_size / server_count
data = zbigarray(data_size)
# Process data in parallel on each server (Map Reduce, Batch, etc)
for server in server_count:
data.activate().process(server*chunk_size, chunk_size)
Out-of-core processing: wendelin.core
# Numpy
np.ndarray(shape=(2,2), dtype="float")
# Out-of-core data
ZBigArray(shape=(1e18,2), dtype="float")
# Full out-of-core
ZBigArray(shape=(1e9,2e9), dtype="float")
Predictive algorithms: scikit-learn
