When performing a hardware event-based sampling collection with the

Intel® VTune™

Profiler

or configuring the result directory for analysis on a mounted share, temporary data files are written to the system global temporary directory. Typically the global temporary directory is

/tmp

.

Depending on the length of the

VTune

Profiler

analysis and data collected, significant temporary disk space may be required. The temporary data may exceed the current allocated or available global temporary storage space. If the system global temporary space is exceeded, the

VTune

Profiler

analysis may fail with a warning similar to the following:

Warning: Cannot load data file `/home/user/r001hs/data.0/tbs0123456789.tb6' (tbrw call…..) failed: Invalid sample file (24)

. Note that the

VTune

Profiler

temporary files may no longer be in the temporary storage location, giving you the false impression that there is plenty of space available. In this case, you may wish to check the temporary storage usage while the analysis is running. If the usage of system temporary storage reaches 100%, this may be the root cause of the error.

If the cause of the error is insufficient temporary disk space, you may set up an alternative temporary directory for collected data.

VTune

Profiler

may still keep writing some scratch files of insignificant size (for example, the socket file

sep_ipc_socket_0

) to the system global temporary directory. However, it will utilize the defined alternative temporary location for the larger files such as those beginning with

lwp

(for example,

lwp28478__wallclock.tb7

,

lwp28478_user.mrk

,

lwp28478_7.txt

). When the

VTune

Profiler

completes finalization, all temporary scratch files are automatically removed.
