3869* Purpose
3870* =======
3871*
3872* PILAENV returns the logical computational block size to be used by
3873* the PBLAS routines during testing and timing. This is a special ver-
3874* sion to be used only as part of the testing or timing PBLAS programs
3875* for testing different values of logical computational block sizes for
3876* the PBLAS routines. It is called by the PBLAS routines to retrieve a
3877* logical computational block size value.
3878*
3879* Arguments
3880* =========
3881*
3882* ICTXT (local input) INTEGER
3883* On entry, ICTXT specifies the BLACS context handle, indica-
3884* ting the global context of the operation. The context itself
3885* is global, but the value of ICTXT is local.
3886*
3887* PREC (dummy input) CHARACTER*1
3888* On entry, PREC is a dummy argument.
