Central Ancillary Program
(CAP)
Generate your own ancillary files
March 2014
• Ancillary files are in UM format – use xconv to inspect content
• Where can you find ancillary files?
– Met Office (via CMS)
– National HPC service - for example in $UMDIR/vnX.Y/ancil
– For vn6.1

• Standard ancillary files (to run LAM typically)
– use CAP hosted by NCAS-CMS

CAP architecture
Web server
PUMA
serves ancillary files
User browser
request
Local compute
generates data
Local compute polls the Web server every 15 mins
Files remain on PUMA for 7 days

NCAS-CMS CAP – not the very latest version, but we are constantly upgrading
CAP runs on MONSooN and HECToR but neither have the web interface –
note you consume AUs running the CAP on HECToR (very little need for
parallel processing, memory is more of an issue).
Willie McGinty is developing the CAP to run on the supercomputer – better
for code maintenance and management
CAP also runs on the Large Memory Server (LMS) attached to HECToR (free)
again no web interface
NCAS-CMS CAP interface does not expose all the capabilities of the CAP
