These commands report the current state of LaGriT's dynamic memory allocation. LaGriT arrays are referenced by memory management by a two part name, block name and partition name. It is allocated in integer or real blocks(real is implemented as real*8). Each memory block is preceeded by a header and terminated by a trailer. Different platforms will have different values for integer and real word lengths. LaGriT developers read more on LaGriT memory management at Memory Manager

The following memory keywords are recognized:
memory / verify  
verify the integerity of LaGriT memory manager storage by checking that the known blocks have not been overwritten. If corruption is detected, an array map will be printed. Nothing is printed if there memory is successfully verified.

memory / print  
print an address map of the LaGriT managed arrays. For each array the following is printed; index, length, type, memory address, associated name, and partition. The partition is the grouping of arrays by usage. Common partitions include the mesh object (by name), global memory, and temporary memory for work arrays.

 Sizeof char    (type 3) =  1 bytes      Sizeof long        =   4 bytes
 Sizeof real*8  (type 2) =  8 bytes      Sizeof pointer     =   4 bytes
 Sizeof integer (type 1) =  4 bytes      Sizeof INT_PTRSIZE =   4 bytes

memory / maxmalloc  
Report estimate of possible amount of memory available for allocation by LaGriT. This test will make incremental calls to internal LaGriT memory allocation (mmgetblk) until failure. The report will include the total Megabytes where allocation succeeded, and amount at which allocation failed. This command will also print a map of the memory manager storage.

The 64 bit version for memory routines will look slightly different:
 Sizeof char    (type 3) =  1 bytes      Sizeof long        =   8 bytes
 Sizeof real*8  (type 2) =  8 bytes      Sizeof pointer     =   8 bytes
