Syntax
FLUSH-PREFIX <directory name>
Variable
VT_FLUSH_PREFIX
Default
Content of environment variables or
/tmp
Description
Specifies the directory of the flush file. It can be an absolute or relative pathname; in the latter case, it is interpreted relative to the current working directory of the process writing it.
On Unix* systems, the flush file of each process is created and immediately removed while the processes keep their file open. This has two effects:
  1. if processes get killed prematurely, flush files do not clutter the file system
  2. during flushing, the remaining space on the file systems gets less although the file which grows is not visible anymore
The file name is
VT-flush-<program name>_<rank>-<pid>.dat
, with
<rank>
being the rank of the process in
MPI_COMM_WORLD
and
<pid>
the Unix process id.
A good default directory is searched for among the candidates listed below in this order:
  1. first folder with more than 512MB
  2. failing that, folder with most available space
Candidates (in this order) are the directories referred to with these environment variables and hard-coded directory names:
  1. BIGTEMP
  2. FASTTEMP
  3. TMPDIR
  4. TMP
  5. TMPVAR
  6. /work
  7. /scratch
  8. /tmp

Product and Performance Information

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
