Binary File Family Member Size
Binary file family member size
In D3PLOT 8.0 onwards the determination of binary file family member size is automatic by default. D3PLOT takes the actual size of files, rounded up to the nearest Mbyte, as being the effective size for a given family and no further intervention by the user is required.
| This can be overridden by giving an explicit size when the file is opened, or subsequently, or by setting the environment variable FAM_SIZE to an explicit size in MB. For example on a UNIX system: | |
| setenv FAM_SIZE 1 | (1MByte family, C shell syntax) |
| FAM_SIZE=9, export FAM_SIZE |
(9MByte family, Bourne shell syntax) |
Any family size is legal, but it is suggested that it be a multiple of 1MByte on single precision machines. On machines generating double precision (64 bit) output files the same numbers (ie 1 and 9 in the examples above) should be used, but the actual file sizes will be 2 and 18 MBytes respectively. This is covered in more detail in Setting the family member size of database files
