86 C Particularly weird and obscure voodoo numbers
87 C lShare - This wants to be the length in
88 C [148]-byte words of the size of
89 C the address "window" that is snooped
90 C on an SMP bus. By separating elements in
91 C the global sum buffer we can avoid generating
92 C extraneous invalidate traffic between
93 C processors. The length of this window is usually
94 C a cache line i.e. small O(64 bytes).
95 C The buffer arrays are usually short arrays
96 C and are declared REAL ARRA(lShare[148],LBUFF).
97 C Setting lShare[148] to 1 is like making these arrays
98 C one dimensional.
99 INTEGER cacheLineSize
100 INTEGER lShare1
101 INTEGER lShare4
102 INTEGER lShare8
103 PARAMETER ( cacheLineSize = 256 )

118 C-- COMMON /EEPARAMS_L/ Execution environment public logical variables.
119 C eeBootError - Flag indicating error during multi-processing
120 C eeEndError initialisation/termination.
121 C fatalError - Flag used to indicate that the model is ended with
122 C an error
123 COMMON /EEPARAMS_L/ eeBootError, fatalError, eeEndError,
124 & useCubedSphereExchange
125 LOGICAL eeBootError
126 LOGICAL eeEndError

129
130 C-- COMMON /EPARAMS_I/ Execution environment public integer variables.
131 C errorMessageUnit - Fortran IO unit for error messages
132 C standardMessageUnit - Fortran IO unit for informational messages
133 C scrUnit1 - Scratch file 1 unit number
134 C scrUnit2 - Scratch file 2 unit number
135 C eeDataUnit - Unit number used for reading "execution environment" parameter file.
136 C modelDataUnit - Unit number for reading "model" parameter file.

138 C pidIO - Id of process to use for I/O.
139 C myBxLo, myBxHi - Extents of domain in blocks in X and Y
140 C myByLo, myByHi that each threads is responsble for.
141 C myProcId - My own "process" id.
142 C myPx - My X coord on the proc. grid.
143 C myPy - My Y coord on the proc. grid.
144 C myXGlobalLo - My bottom-left (south-west) x-index
145 C global domain. The x-coordinate of this
146 C point in for example m or degrees is *not*
147 C specified here. A model needs to provide a
148 C mechanism for deducing that information if it
149 C is needed.
150 C myYGlobalLo - My bottom-left (south-west) y-index in
151 C global domain. The y-coordinate of this
152 C point in for example m or degrees is *not*
153 C specified here. A model needs to provide a
154 C mechanism for deducing that information if it
155 C is needed.
156 C nThreads - No. of threads
157 C nTx - No. of threads in X
158 C nTy - No. of threads in Y
159 C This assumes a simple cartesian
160 C gridding of the threads which is not required elsewhere
161 C but that makes it easier.
162 C ioErrorCount - IO Error Counter. Set to zero initially and increased
163 C by one every time an IO error occurs.
