Memory management
type: item
description: There seems to be some peculiarity in the way IDL does its memory management in the TRANSPOSE function. Running on a VAXstation 3100/76, the following statements cause the process to hang: IDL> A = FINDGEN(3,200000) IDL> A = TRANSPOSE(A) The problem can be made to disappear as the arry size is made smaller, presumably depending on one's page file quota and so forth. (On our system, using A = FINDGEN(3,100000) works fine.) The problem is definitely in IDL and not in the system: when we LINKIMAGE a functionally-equivalent transpose function written in C, it works fine with the large array. Anybody have any ideas about this? Rich Isaacman COBE Project NASA/Goddard Space Flight Center
