翻译 (4) FOR MULTI-PROCESS EXECUTION, THE ESTIMATED VALUE OF FLOATING POINT OPERATIONS FOR EACH PROCESS IS BASED ON AN INITIAL SCHEDULING OF OPERATIONS AND MIGHT NOT REFLECT THE ACTUAL FLOATING POINT OPERATIONS COMPLETED ON EACH PROCESS. OPERATIONS ARE DYNAMICALLY BALANCED DURING EXECUTION, SO THE ACTUAL BALANCE OF OPERATIONS BETWEEN PROCESSES IS EXPECTED TO BE BETTER THAN THE ESTIMATE PRINTED HERE. (5) THE UPPER LIMIT OF MEMORY THAT CAN BE ALLOCATED BY ABAQUS WILL IN GENERAL DEPEND ON THE VALUE OF THE "MEMORY" PARAMETER AND THE AMOUNT OF PHYSICAL MEMORY AVAILABLE ON THE MACHINE. PLEASE SEE THE "ABAQUS ANALYSIS USER'S MANUAL" FOR MORE DETAILS. THE ACTUAL USAGE OF MEMORY AND OF DISK SPACE FOR SCRATCH DATA WILL DEPEND ON THIS UPPER LIMIT AS WELL AS THE MEMORY REQUIRED TO MINIMIZE I/O. IF THE MEMORY UPPER LIMIT IS GREATER THAN THE MEMORY REQUIRED TO MINIMIZE I/O, THEN THE ACTUAL MEMORY USAGE WILL BE CLOSE TO THE ESTIMATED "MEMORY TO MINIMIZE I/O" VALUE, AND THE SCRATCH DISK USAGE WILL BE CLOSE-TO-ZERO; OTHERWISE, THE ACTUAL MEMORY USED WILL BE CLOSE TO THE PREVIOUSLY MENTIONED MEMORY LIMIT, AND THE SCRATCH DISK USAGE WILL BE ROUGHLY PROPORTIONAL TO THE DIFFERENCE BETWEEN THE ESTIMATED "MEMORY TO MINIMIZE I/O" AND THE MEMORY UPPER LIMIT. HOWEVER ACCURATE ESTIMATE OF THE SCRATCH DISK SPACE IS NOT POSSIBLE. (6) USING "*RESTART, WRITE" CAN GENERATE A LARGE AMOUNT OF DATA WRITTEN IN THE WORK DIRECTORY.

(4) 对于多进程执行,每个进程的浮点操作的估计值基于初始操作调度,可能不反映每个进程上实际完成的浮点操作。操作在执行过程中动态平衡,因此进程之间操作的实际平衡预计将比此处打印的估计更好。
(5) 可以分配给ABAQUS的内存上限通常取决于"MEMORY"参数的值和机器上可用的物理内存量。请参阅"ABAQUS分析用户手册"获取更多详细信息。内存和磁盘空间的实际使用取决于此上限以及最小化I/O所需的内存。如果内存上限大于最小化I/O所需的内存,则实际内存使用量将接近估计的"最小化I/O内存"值,并且临时磁盘使用量将接近零;否则,实际内存使用量将接近先前提到的内存限制,并且临时磁盘使用量将与估计的"最小化I/O内存"和内存上限之间的差异大致成比例。但无法精确估计临时磁盘空间。
(6) 使用"*RESTART,WRITE"可以生成大量数据写入工作目录。
