6.10.1 Resource Requirements
Support for RADEON graphics requires the following system-wide resources:
• 2 global sections
• 296 KB of global memory
In addition, each RADEON card requires the following:
• 3 global sections
• 16 MB plus 1 page of global memory
• 16 MB plus 1 page of buffer object space (32-bit System Space Windows)
The global sections are charged against the GBLSECTIONS system resource, and
the 16+ megabytes of global memory are charged against the GBLPAGES and
GBLPAGFIL resources.
For example, a single RADEON card requires the following:
• 5 global sections
• 16MB+8KB+296KBglobal memory
These numbers equate to the following values:
GBLSECTIONS 5
GBLPAGES 33376 (GBLPAGES is in units of 512-byte pagelets.)
GBLPAGFIL 2086 (GBLPAGFIL is in units of 8192-byte Alpha pages.)
A 4-card configuration requires the following:
• 14 global sections
• 296 KB + 4*16 MB + 4*8 KB = 64 MB + 328 KB global memory
These numbers equate to the following values:
GBLSECTIONS 14
GBLPAGES 131728 (GBLPAGES is in units of 512-byte pagelets.)
